Which is the smallest jet in the world?

LCA is the first domestically developed modern supersonic fighter developed by India, and it is also the world's smallest jet multirole fighter. Recently, the Aviation Development Agency under the Ministry of Defense of India officially announced that the first modernized multi-role supersonic fighter (LCA) will be delivered to the Air Force in mid-2007. At that time, the LCA will become one of the very few domestically produced advanced fighters in the air forces of Asian countries, and it will also be the smallest modern multi-role jet fighter in the air forces of Asian countries.

The German "little viper" in World War II was not actually an airplane, but a rocket launcher piloted by a human, and the German "crow" in World War II was the smallest jet fighter.

China's J-12, known as the "Li Xiangyang in the air", is small and flexible.

The entrance of the Beijing Museum of Aeronautics and Astronautics is a real machine, which is too small for many people to think is a model.

It's a pity that it is not very practical and is not mass-produced.

German Viper.

It was the era of World War II.

Not an Indian LCA fighter at all.

The landlord will know this by looking at this.

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.

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.

On August 27, 1939, the world's first jet aircraft, the HE178, took to the skies.

August 27, 1939, a hot summer day. Pilot Flüg Capitan Erich Vasitz arrived on the tarmac as usual, where a newly built Heinkel airplane was parked. Unlike the usual aircraft, the aircraft, known as the HE178, was equipped with a HES3B turbojet with a thrust of 838 lbs (380 kg) developed by von O'Hain.

Vasitz boarded the plane, activated the accelerator, and with the huge roar of the engine, the world's first jet plane soared into the blue sky, and the deafening sound announced the arrival of the jet age.

It appeared during World War II, in the United Kingdom.

In 1949, the first jet airliner made its first flight of the British Comet.

The world's first truly practical jet aircraft is widely believed to have been the first successful test flight of the Heinkel He 178 in Nazi Germany on August 27, 1939.
