ABSTRACT:
The assistant landing device of a troubled airplane of the present invention comprises a storing chamber under the front end of the airplane, which has a freely opened door, and a strengthen network the front end of which is connected with the airplane body. When the network is expanded from the storing chamber, it will not affect the descent of the front and back landing gears. A plurality of canopy packets arranged as an array are installed on the front and back sides of the network and may be opened by controlling so that a group of canopy packets are formed on the right and left sides of the body of the airplane so that the airplane may be descended slowly. Each of the canopy packets has a large and a small canopy packets and a gas container for being quickly charged with air so that the small canopy packet may be opened. A plurality of positioning parachutes are located on the distal end of the network, which may be opened by the applied force of the wind in order that the strengthen network will be expanded uniformly below the canopy body. The present invention has further provided a network cover the end portion of which has a decoupled parachute being controlled to expand in order that the network cover can be decoupled from the network.
