|opis:||The landing of aircraft is generally divided into land forced landing and water forced landing. Land landing means landing site on land. Water landing means landing site in the sea, lakes and other water, water landing requirements as close as possible to land, water landing danger is higher than land landing. When landing in the airport, if the landing gear can not be automatically lowered or put down with hand control, such as manual invalid, then the use of gravity release, the aircraft in a smooth airflow dive to the speedometer red line, will produce 3.8G of gravitational acceleration, landing gear weight increased 3.8 times times, and then put down. If the release of gravity is not effective, then use the abdominal wipe ground landing, and as far as possible to consume light fuel, so as not to catch the plane on fire. Forced landing is generally preventive, should be acute, because of forced landing on the drop environment and aircraft performance requirements are very high, so there is also a greater risk. It is often possible to cause the destruction of the aircraft. Today, tens of millions of airliners travel to and from major airports around the world every day. Admittedly, the invention of the aircraft has brought us great convenience, but aviation accidents have also brought disaster to some people in the world. When the plane has a problem and the landing gear is damaged, it needs an emergency landing, which is more dangerous, so it is necessary to develop the aircraft carrying the landing by the unmanned vehicle.
The cart is fitted with a small sloping landing version to catch the landing plane, which is arranged intensively by highly elastic ropes to hook the landing plane so that it does not break away from the cart and slows down after the plane lands into the cart until it stops. Because the aircraft will have a great impact when forced landing, so in the small car on the four wheels installed spring, the plane after landing spring compression,
