Title:
A PARACHUTE-LANDING DEVICE OF AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2007/076725
Kind Code:
A1
Abstract:
A parachute-landing device of aircraft is provided. The device includes at least a parachute compartment (4) in aircraft (1). A parachute (2) with a pilot parachute (3) is contained within the compartment. The compartment (4) has a cover (5), which can be controlled to open or close. The parachute (2) is placed in the space formed by the compartment (4) and the cover (5). The end of a parachute sling is fixed to the compartment (4). A guide duct (11) facing to the windward side is provided in the compartment (4). The duct has an air inlet (12) at front end and an air outlet (13) at rear end. When the cover (5) is closed, the inlet (12) is enveloped by the cover (5). The outlet (13) is located in the compartment (4). The pilot parachute (3) is lied over the outlet (13). The deployment of the parachute without exterior power source improves the reliability of the opening operation, therefor the daily maintenance is omitted. Due to the design of tower type parachute and rope reel with disk spring, the pulling force between the parachute and aircraft during deployment is efficiently reduced, and the buffering power during deployment can be sufficiently afforded. Therefore the parachute landing of large-scale aircraft is enabled.
