Homemade flying machines. Do-it-yourself aircraft: design requirements and tips

One of the presented models of flying machines was created by Anatoly Zhukov, a resident of Bashkortostan, who has been developing improvised aircraft for 36 years. The video shows only some of his cars. Analogues of his flying machine have not yet been found.

A 40 liter tank is enough for about 2 hours. Anatoly tells what his miracle device consists of. Conventional bogie, two wings and a power plant with an engine. The experimental model requires a lot of patience and time. It takes 1.5 to 2 years to develop and manufacture.

Anatoly Zhukov has been engaged in his favorite hobby since 1976. Then he created the Deltaclub in Ufimsky aviation institute. In 1980, having the education of UGATU, he began to invent his own home-made aircraft. Then he came up with a seemingly crazy idea - to supply a hang glider with an engine. Now the inventor has more than twenty models on his account. Each time they become more versatile and safer. A. Zhukov: “At first they made three-wheeled hang gliders, I tumbled twice on them. That is, they are not very stable during takeoff and landing.”
The inventor is often visited by guests from abroad. After all, analogues of such devices cannot be found all over the world. They came from China, Abkhazia, the USA. The latest model invented by Anatoly "Zhuk-44". She has an engine from a VAZ car with a capacity of 90 horsepower. The Beetle works on regular 95th gasoline. The inventor complains: the hobby is exciting, but very costly. But on such a car you can drive 200 km (with two fuel tanks) and Anatoly has already figured out how to increase the flight range.

flight simulator

A flight simulator is a device or computer program, which displays the behavior of the aircraft (plane, glider, helicopter, etc.) in flight and its other phases. A flight simulator can be both complex and complex "computer game" as well as complex systems training of pilots, with a cockpit replica mounted on a hydraulic platform or reloading centrifuge, simulating the sensations of movement.

story

The first training simulators were created during the First World War. However, they were not widely used. In 1934 alone, the USAF acquired four communications trainers (known as "Blue Box"), which were used for instrument flight training. During the Second World War, devices of this type were already widely used for the training of Allied pilots. The first aircraft simulator used by the airline was a Curtiss-Wright Boeing 377 simulator purchased in 1948 by Pan Am.

Early flight simulators used visualization systems based on a mobile camera moving along a ground scale and transmitting an image to a monitor in front of the pilot.

Types of simulators

There are several types of flight simulators:

Full Flight Simulator (FFS) is the most technologically advanced type of flight simulator. Complete, full size and functional cockpit replica of this type, model or series of aircraft in combination with the appropriate computer system necessary to reproduce the aircraft during ground and air operations. The visualization system provides a view outside the cab, while the drive system reproduces the sensations of movement. Devices of this type are used, in particular, for the training of flight personnel in hazardous conditions flight, developing appropriate skills.

Flight Training Device (FTD) is a complete, full-size and functional copy of the instruments, equipment and control panels of this type of aircraft, in combination with the appropriate computer system necessary to reproduce the aircraft in ground and air conditions. Devices of this type should not be equipped with visualization systems and the display of motion sensations.

Flight and Navigation Procedures Instructor (FNPT) – a cockpit model, connected to an appropriate computer system, necessary to represent a given type or a given group of aircraft types during flights. Devices of this type are used, in particular, for procedural flight training and navigation.

Basic Instrument Training Device (BITD) is a device that displays aircraft (they can be displayed on a monitor screen), which allows you to teach at least the procedural aspects of instrument flight.

Many flight simulators are present in the PC game market. Here are some of them:

FlightGear is a flight simulator based on the GNU GPL. designed for many system platforms

Flying Unlimited – symulatory Lotnicze Firmy Through the Looking Glass Technology

Microsoft Flight Simulator - A series of some of the most popular civilian flight simulators

Combat Flight Simulator is a World War II aircraft simulator built on the Microsoft Flight Simulator engine

Orbiter - free space simulator

X-Plane is an airplane simulator with interesting solutions(Vector graphics)

IL-2 Sturmovik - one of the best combat flight simulators from World War II

According to experts, light aviation in Russia is living its life with an obscure prospect. Aviators have nowhere to study - pilot training centers are closing, problems with registration, maintenance and repair of aircraft.

Nevertheless, the number of amateur aviators has doubled over the past five years, although not everyone can afford to buy and maintain an aircraft. According to statistics, almost every second amateur aviator is also a self-made designer - he chooses and repairs his aircraft himself.

HELICOPTER FROM IMPROVED TOOLS

The hobby of a 75-year-old amateur aircraft designer from Baksan is not supported by his sons and wife. Time and money down the drain, they say. But despite this, the life of Safarbi Batyrgov is wonderful. He is passionate, excited and confident that he will definitely achieve his goal.

To make a dream come true, everything that is at hand is used: a diesel engine of an old foreign car, a pulley and a seat belt from washing machine. To increase the engine speed, the details of the iron bed from the 50s are perfect.

Correspondents of the program "Special Report" learned how to build their own aircraft.

He has been drawn to the sky and aviation since his school days. But life turned out so that it was necessary to help the family. After a decade, Safarbi went to work: first at construction sites, then, due to illness in his legs, he got a job as a bathhouse attendant.

His first helicopter, however, wooden, he designed right in the yard of the bathhouse. But he was not allowed to fly, and the police confiscated the helicopter for security reasons. Thirty years have passed since then. Now the iron bird has replaced the wooden one.

“The calculations are all in my head! There are no drawings. I know everything! - the designer is sure.

However, the likelihood that Safarbi's brainchild will rise at least half a meter above the ground is very low. Nevertheless, the designer intends to carry out his first flight at all costs.

FLYING TRUCK

But Andrei Sargsyan from Pyatigorsk was able to take off the ground in his helicopter by one and a half meters. It doesn't matter that this craft landed on its right side. A professional singer and musician, he works part-time at local restaurants in the evenings. I became interested in designing peculiar aircraft eight years ago. During this time, collected four helicopters.

“Only one flew, but then I had to sell its engine, because funds were needed,” Andrey admits.

Engines from motorcycles "Izh" and "Java", large homemade machines and machines for cutting metal and even a bushing from the tail rotor of the Mi-2 - in general, a pile of metal, iron, plastic and incomprehensible material for the inhabitants clogged the yard, garage and basement of the master.

In order to fly on devices of his own design, Sargsyan is trying to get a pilot's license.

WHAT IS "BEGOLET"

Professional aircraft designer Alexander Begak made his first aircraft at the age of six. It was the rocket that blew up the children's room. Six years later, Alexander built his first aircraft.

"Begolet" was invented because of our roads. You can land anywhere on it, drive for bread or provide first aid, give injections and fly away. After all, if the rain has passed, you can’t drive anywhere in Russia. This is how Begolet was born, - says Alexander Begak, General Designer, Chairman of the Discrete-Innovative Small Aviation Cluster.

Our country will not be able to do without small aircraft, the designer believes. AT Soviet time local airlines provided full coverage of both the center of Russia and Far East and Siberia. Then only the Pyatigorsk air squadron consisted of more than 350 small aircraft. Today, there are no more than three thousand such devices in the whole of Russia, and all of them are in private hands.

DIFFICULTIES OF FLIGHT

Most pilots cannot afford to repair aircraft in specialized salons. There are only a few of them throughout the country. Plus, it's expensive. Repair of a small aircraft will cost as much as new car, so the pilots try to do everything on their own.

To get a pilot's crust, now you have to pay almost 700 thousand rubles. At the same time, there is nowhere to study especially - aviation training centers almost gone. Affording the purchase of an aircraft and obtaining certification is also an expensive pleasure. There is only one aircraft check-in desk for the whole country - in Moscow.

In addition, it is necessary to renew the maintenance of the aircraft every year. The cost of the document is about 150 thousand rubles.

“The process is organized in such a way that it requires not real Maintenance, but they are forced to simply buy this piece of paper through commercial structures. It turns out that you have to buy a document, and then go to the mechanic and pay the same amount so that he does the annual maintenance, ”complains pilot Eduard Losev.

So far, all small aviation is based on the enthusiasm of those who can no longer do without the sky. There is no benefit to aviators from this - sheer pleasure.

The desire to fly never disappeared from a person. Even today, when traveling by plane to the other side of the planet is a completely common thing, I want to assemble at least the simplest aircraft with my own hands, and if you don’t fly yourself, then at least fly in the first person with the help of a camera, for this they use unmanned vehicles. We will review the most simple designs, schemes and drawings and, perhaps, we will realize our old dream ...

Requirements for ultralight aircraft

Sometimes emotions and the desire to fly can defeat common sense, and the ability to design and correctly carry out calculations and plumbing work is not taken into account at all. This approach is fundamentally wrong, and therefore, several decades ago, the Ministry of Aviation prescribed General requirements to homemade ultralight aircraft. We will not give the entire set of requirements, but will limit ourselves to only the most important ones.

  1. A self-made aircraft must be easy to operate, easy to fly on takeoff and landing, and the use of non-traditional methods and control systems of the device is strictly prohibited.
  2. In the event of an engine failure, the aircraft must remain stable and ensure safe gliding and landing.
  3. The takeoff run of the aircraft before takeoff and takeoff from the ground is not more than 250 m, and the takeoff speed is at least 1.5 m/s.
  4. The effort on the control sticks is within 15-50 kgf, depending on the maneuver being performed.
  5. Clamps of aerodynamic steering planes must withstand an overload of at least 18 units.

aircraft design requirements

Since an aircraft is a means of increased risk, the use of materials, steels, cables, hardware of components and assemblies of unknown origin is not allowed when designing an aircraft structure. If wood is used in the structure, then it must be without visible damage and knots, and those compartments and cavities in which moisture and condensate can accumulate must be equipped with drainage holes.

The use of bent pipes and rods is highly undesirable, especially in cases where they have a high compressive / tensile load. All threaded fasteners must have a lock, and movable swivel joints must be equipped with a mechanical stop. Growers and self-locking nuts are not used. Cables cannot have knots and damage to the cores and must be treated with an anti-corrosion compound.

How to build a high wing. Drawings and diagrams of models

The simplest version of a motorized aircraft is a monoplane with a pulling motor propeller. The scheme is quite old, but time-tested. The only drawback of monoplanes is that it is quite difficult to leave the cockpit in emergency conditions, the monowing interferes. But by design, these devices are very simple:

  • the wing is made of wood according to the two-spar scheme;
  • welded steel frame, some use riveted aluminum frames;
  • sheathing combined or linen completely;
  • closed cabin with a door operating according to an automobile scheme;
  • simple pyramidal chassis.

The drawing above shows a Malysh monoplane with a 30-horsepower gasoline engine, a take-off weight of 210 kg. The aircraft develops a speed of 120 km / h and has a flight range with a ten-liter tank of about 200 km.

High-wing strut design

The drawing shows a single-engine high-wing Leningradets, built by a group of St. Petersburg aircraft modellers. The design of the device is also simple and unpretentious. The wing is made of pine plywood, the fuselage is welded from steel pipe, classic linen lining. Wheels for the landing gear - from agricultural machinery in order to be able to carry out flights with a start from unprepared soils. The engine is based on the design of the MT8 motorcycle engine with 32 horsepower, and the take-off weight of the device is 260 kg.

The device proved to be excellent in terms of controllability and ease of maneuvering, and for ten years it was successfully operated and took part in rallies and competitions.

All-wood aircraft PMK3

The all-wood apparatus PMK3 also showed excellent flight qualities. The aircraft had a peculiar nose shape, a landed landing gear with small-diameter wheels, and the cockpit had an automobile-type door. The aircraft had an all-wooden fuselage with canvas skin and a single-spar wing made of pine plywood. Installed on the device outboard motor Whirlwind 3 with water cooling.

As you can see, with certain skills in design and engineering, you can not only make a working model of an aircraft or a drone, but also a completely complete simple aircraft with your own hands. Be creative and dare, successful flights!

    How to make your own flying machine

    Aeromodelling attracts both children and adults who want to create with my own hands working models of gliders and airplanes. Despite the fact that a large assortment of various aircraft models is presented in stores today, it is much more interesting to make your own model that reproduces the features of a real glider and is able to fly. We will tell you how to assemble a flying glider in this article.

    Sponsored by the placement of P&G Articles on the topic "How to make your own flying machine" How to make a model glider How to build a glider How to make a mask with your own hands

    Start making the model with a full size working drawing. For the drawing you will need big leaf paper, square, pencil and ruler. First, make a drawing of the wing. To do this, draw a straight line on paper and divide it into eight parts.

    Lay the ruler parallel to the drawn line and draw perpendiculars opposite each segment. Set aside the length of the ribs (120 mm) on the extreme perpendiculars. Connect the obtained points with another line. Then make a drawing of the stabilizer and keel.

    For the fuselage use wooden lath 70 cm long with a section of 10x6 mm. You will also need a pine board 6 cm wide and 10 mm thick for the weight, which needs to be sanded.

    For the edges of the wing, take slats 68 cm long and 4x4 mm in section. Make the roundings of the wings from aluminum wire or specially moistened with hot water and thin wooden slats bent around the cylindrical surface.

    Connect the roundings with the edges, fitting them to each other. Also make the same curved ribs for the wing. In order for them to be the same, use a block of wood to bend them, bent in the shape of the upper contour of the wing profile.

    As materials for the ribs, use thin slats 14 cm long and 3x2 mm in section. Reiki must be soaked in hot water and pulled over the wing on the machine.

    On the edges of the wing, make small sockets for installing ribs and glue them inside. After installing the ribs, the wings must be bent into a V-shape by soaking the edges in hot water, and then heating them over a candle flame. To mount the wing, make V-shaped struts from steel wire and pine plank.

    Also take two 40 cm long slats for the stabilizer, and one 40 cm long slat for the keel. Heat them up and bend them.

    To attach the stabilizer to the fuselage, use a wooden plank 11 cm long and 3 mm high. The stabilizer is tied to this bar with threads. Make nests in the bar at the edges of the stabilizer and insert the sharp ends of the keel into them.

    Assemble the whole model and cover it with tissue paper.

    How to make an aircraft?

    • Aircraft drawing
    • Aggregates
    • materials
    • Equipped workshop

    First you need to decide what type of aircraft will be manufactured. So, for example, you can make a glider and hang glider, which is perfect for small quiet solo flights, or you can build a more complex trike or aircraft for long, faster and noisier flights. It all depends on the preferences of the designer.

    The first device is recommended to be made according to the finished drawing, which has been tested by many aviation enthusiasts. It is not recommended to make your own changes, as you can break specifications aircraft, and it simply will not take off. Repetition of the recommended design will protect against many problems in the future and will give the first experience.

    You can find ready-made drawings on how to make an aircraft on the Internet. You can find freely distributed projects, or you can buy someone's individual developments. If this is the first attempt, you must use the free building plan. It has certainly been tested by many amateurs and a huge number of additions have been made to it that can improve the original design.

    When purchasing aggregates and materials for construction, you need to keep receipts, they will be needed if the device is registered for registration, otherwise there will be no opportunity to take to the air.

    It is recommended to start construction under the guidance of a more experienced fashion designer who will suggest a solution. possible problems. If there are no such acquaintances, it is recommended to register on a thematic forum where they discuss how to make a flying machine, and resolve all emerging issues on it.

    It is necessary to accustom yourself to do everything neatly and efficiently from the very beginning. Carelessness should not be anywhere - even in places that are inaccessible to the naked human eye. Otherwise, all the work may go down the drain and you will have to start all over again.

    You will also need a well-equipped room or workshop with a large assortment of hand tools and machines. Working "on the knee" to get the desired result will not work, besides, it will require much more time and effort.

  • I already wrote in the article how the guys from Germany made a multicopter from standard parts for radio-controlled models with their own hands, capable of lifting a person and lifting him into the air, that is, they made the world's first manned flight on an electric multicopter. It was in October last year. But they did not stop there, they did not begin to deal with radio-controlled models, but went further and developed a concept for the development of their project, putting their ideas into it.

    This is the official presentation of the E-Volo 2012 promotional video. At the beginning of the video, you can see the world's first manned flight of a vertical takeoff and landing aircraft, from a purely electric drive. In the second part, you will be able to see the concepts of research into the future of volocopters.

    Pioneer Aviation.

    After more than a year of work on the development of the volocopter VC1, the E-Volo team achieved its goal and on October 21, 2011, the world's first manned vertical takeoff and landing (VTOL) aircraft with a purely electric drive, made its first flight.

    What is a Volocopter?

    The E-Volo Volocopter is a brand new, vertical takeoff and landing (VTOL) manned aircraft that cannot be classified into any known category. The fact is that this model was conceived as a device with a purely electric drive, which distinguishes it from conventional aircraft.
    With the help of its many propellers, the volocopter can take off and land vertically like a helicopter. A significant advantage, besides the simple design, without complex mechanics, is the redundancy of the rotors. This allows the volocopter to land safely even if some propellers or propeller drives fail.

    How does a volocopter work?

    Control in flight is carried out with the help of a joystick, by wire and, in principle, is very easy. Unlike any other VTOL aircraft, the control operation is child's play. The car takes off and lands vertically, and the pilot pays little or no attention to the flight path angle, minimum speed, cockpit position, pitch control, and many other things that ordinary pilots do and that aircraft are so demanding on.
    The propellers generate all the upward force, and by selectively changing the speed of rotation, they simultaneously replace the rudder by changing the direction of movement. In addition, unlike a helicopter, there is no need for mechanical control of the propeller pitch at all.
    Automatic position control, and direction control, is carried out using several independent on-board computers that control the rotation speed of each propeller individually and the multicopter as a whole.
    As an option, you can use another pusher propeller, which will significantly increase the horizontal speed of flight.

    Prospects for the development of Volocopter

    Shared with network famous partners in area scientific research and industry, Volo will forge ahead on the development of volocopter technology over the next year.
    The aim of the cooperation is a two-seat volocopter that complies with safety standards, and is based on the concept of study and evolution of VC 2P, with the following performance characteristics:

    Speed ​​over 100 km/h
    minimum ceiling flight altitude 6500 feet
    takeoff weight 450 kg
    more than one hour flight time

    I understand that one cannot expect substantive comments from our public, but here is how American enthusiasts of unusual aircraft comment on this idea:

    • Absolutely amazing! Can't wait to see the first production models. Volocopter - quadcopters are the future of aviation.
    • I need one, even if it's a bad one.
    • Lots of comments about "it's safe, it's not safe" but no one remembers that a guy named La Cierva developed a very good device... about 80 years ago! Never heard of gyroscopes? Many people didn't know (and don't know now) that major piloting errors occur at low altitude. I believe that the gyroscope is the most necessary, but underestimated instrument of the aircraft. Look at beautiful video here on YouTube, which shows how the gyroscope performs the landing and takeoff of aircraft. Using gyroscopes on such a Volocopter-quadcopter, you can achieve the highest reliability of piloting.
    • It is theoretically the safest manned aircraft design ever made.
    • Ordinary helicopters, as everyone knows, are thousands of parts connected in a complex kinematic chain. Even with a fixed plane, the blades are thousands of individual moving parts. This multicopter has 18 moving parts. That's all.
    • A high degree of redundancy is security. The possibility of engine failure is always inherent, in this case it is not scary.

    What is your opinion?
