The smallest aircraft in the world, weighing only 75 kilograms, what is such a small aircraft used f

The aircraft is used daily for aerial photography, plant protection, and sometimes for rent.

It should be used as a means of transportation for single travel, this plane is not only small, but also very cheap, about 100,000 yuan.

This small plane was invented by the Japanese and can only carry one person at the moment, and it is also very economical, mainly to replace and replace cars.

The smallest aircraft in the world, it is not used to carry goods or people, but to survey the terrain and monitor geological disasters, fires, and mudslides. It is used to prevent danger and fight disasters. Survey aircraft.

The smallest aircraft in the world is a cricket machine.

The overall weight of the cricket machine is only 75 kilograms, which is only as heavy as a stronger adult man, and its height is only meters, which is not even as tall as a 12-year-old child. However, although it is relatively small, it has many internal functions, and a person can fly very comfortably.

Originally designed by a French designer, the Cricket Machine is an ultra-small aircraft that is cheaper than the smallest car in the world, and even cheaper than a regular car. But even if it is such a small aircraft, such a cheap **, it has a lot of functions, basically ordinary aircraft have it, and it is small and lightweight, so it is very suitable for personal short-distance flight.

Wing design of a cricket machine

Cantilever rectangular lower wing, the relative thickness of the airfoil is calculated according to the chord length of 48 cm, and the maximum thickness is in cm), the reverse angle on the wing is 4 degrees, the wing root installation angle is 1 degree, the wingtip is -30 seconds, and there is no sweep angle. The wing is a single-beam box structure, the main beam is two edge strips riveted to a web, both made of AU4G aluminum, the beam has a certain twist angle along the wingspan direction, and one end is similar to the "fork tongue" on the glider, which is used to quickly connect with the fuselage (only 2 minutes).

The wing ribs are cut from klegecell, a polyurethane foam, and there are 70 pieces in total. The skin is a single AU4G aluminium sheet with a pre-formed leading edge (which is difficult to mask directly), after which it is bonded to the ribs and beams. Each wing has an aluminum rib at each end.

On the trailing edge of the wing are connected two full-length flaperons (5 degrees upwards and 30 degrees downwards when used as flaps; When used as ailerons, it is 8 degrees upward and 5 degrees down), it is a beamless monocoque structure, each block has 4 metal ribs (one at each end and two joints), the full length is filled with 20% chord length of klegecell foam, and each flaperon has a ball connection at the root to connect with the control system. With the exception of the modification with a wingtip drop tank, which had an aluminum pipe running through the wing box, no rigids or connecting rods were used to pass through.

The smallest aircraft in the world is a cricket machine, which comes from France. The plane weighs only 75 kilograms, which is not much different from some strong adult men. The height is only meters, which may not reach the height of a 12-year-old child.

Although it is small in size, it has many features inside that allow a person to enjoy flying comfortably.

At first, the cricket machine was designed by a French designer. At launch, it cost 100,000 yuan, which is cheaper than the smallest car in the world. Although it is a very small aircraft, it is also very easy to return, but it basically has all the functions of an ordinary aircraft, and it is light and compact, which is very suitable for a short flight by one person.

It may be that the cricket machine looks like a model machine from the outside, but its flight speed is not very bad, and the flight speed can reach 293 kilometers per hour. Mainly because its piston engine is 120cc and can reach 12 horsepower. Even an obese person weighing 180 pounds can still fly this plane.

And this cricket machine is very convenient to assemble. If you are a very skilled operator, it only takes about 5 minutes to assemble the whole aircraft. At the same time, according to state regulations, if you want to fly this plane, there are no very strict requirements, and you may not even need a driver's license.

After all, the aircraft weighs less than 116 kilograms, and only people with 10 hours of flying experience are required to fly.

Take the planes of the two major aircraft manufacturers that are common in China as an example, and take a look at the weight of the aircraft. First of all, the classic and more common Boeing-737, this series has four models, the approximate fuselage is about 40 tons, the maximum take-off weight is about 80 tons, this is also a relatively small and light model in civil airliners, its flight speed is relatively fast, generally used for short-distance flights.

The same very common Airbus A320 series, this series of aircraft weighs about 40 tons, the maximum take-off weight is basically not more than 80 tons, it is also an aircraft suitable for short-haul flights, and such airliners generally cannot carry too much luggage.

Most aircraft are made up of the following six main parts: wings, fuselage, tail, landing gear, control system, and power plant. Each of them has its own unique function.

The fuselage is mainly used to carry personnel, cargo, fuel, ** and on-board equipment, and through it, the wings, tail, landing gear and other components are connected into a whole. In light aircraft, fighter planes, and attack aircraft, the engine is often installed in the fuselage.

Wings usually have straight wings, swept wings, delta wings, etc. The front and rear green of the wing are basically straight and the leading edge and trailing edge of the wing are swept backward is called the swept wing;

The delta wing is called a delta wing with a triangular plane shape, the former is suitable for low-speed aircraft, and the latter two are suitable for high-speed aircraft. Recently, advanced aircraft have also adopted planar shapes such as edge strip wings and forward-swept wings.

"A380" has a maximum take-off weight of 550 tons.

The A380 "is 73 meters long, has a wingspan of 1 meter, a tail height of 1 meter (equivalent to an 8-story building), a dead weight of 240 tons, a maximum take-off weight of 550 tons, and a maximum load of 150 tons. The cabin is meters long and meters in diameter, and its internal space capacity reaches 1,100 cubic meters, which can park at least 20 double-decker buses, which can be called the "Airmaster". The "A380" has surpassed the "Boeing 747" to become the world's largest civil airliner so far, and its advent has also ended the situation of the "Boeing 747" dominating the world of large passenger aircraft for 30 years.

In order to make this behemoth fly into the sky, Airbus began in June 1994, spent 10 years, spent 10 billion euros, combined with the scientific research, design and production forces of France, Germany, Britain and Spain, and introduced the world's most advanced materials, systems and process technology.

The former Soviet Union An-225 has a maximum take-off weight of 640 tons.
