The invention combines the use of two types of energy. It relates to an auxiliary pyrotechnic device operating in complete autonomy without using any source of energy or the control appliances of the aircraft. The device provides ultimate emergency manoeuvring in the event of complete blockage of the deployment of the landing gear. Said device is autonomous and generates a high level of hydraulic power from a reserve of hydraulic oil compatible with that of the aircraft stored at zero pressure in actuating cylinders actuated by a pyrotechnic charge stored in a gas generator. The technique of said device consists in using the force of the solid gases (propellant) to create a high hydraulic pressure that can move the cylinders and the hooks of the landing gear. The design of said device is characterised by the duplication of the components so as to reduce risk of failure. |
