Cause the serious consequence of fatal crass.In order to solve the above problems, scientific research personnel has spent all thought, finds out many good methods,
Such as water landing, rice field landing etc., civil aircraft handling capacity of passengers is relatively more, and the driver of aircraft is the treasure of country, flies
Machine cost is high, when aircraft breaks down, how to realize aircraft and personal security landing, is that we are thinking deeply needs solution always
Problem.
It is well known that kinetic energy during aircraft landing：W=1/2 × m × v2, quality of the m for aircraft, landing speed of the v for aircraft
Degree, is divided into horizontal sinking speed and vertical landing speed.For example, nearly hundred tons of the maximum take-off weight of airbus A320, Boeing
The maximum take-off weight of 747 airliners is nearly 400 tons, though the weight of military aircraft is light, civil aircraft, military aircraft landing
When speed, 200 kilometers/hour or so of horizontal velocity, from above-mentioned formula as can be seen that aircraft out of control when, kinetic energy is very
Greatly, conventional method is not enough to horizontal kinetic energy is reduced to zero in a short period of time, eliminates to aircraft and the wound of persons on board
Evil.It is badly in need of a kind of aircraft safety landing-gear in actual life.
