A new type of crew air emergency hatch

Abstract

The invention belongs to the design technology of an aircraft emergency hatch, and proposes a brand-new design scheme for an emergency hatch for aircrew skydiving. A windshield door cover, the passage door includes a passage door cover, two bolt lock lock holes are respectively arranged on both sides of the passage door cover, two spring bolt locks are respectively arranged at the corresponding fuselage door frames on both sides of the passage door cover, and the spring bolt lock Correspondingly installed with the lock hole, the channel door cover is fixed on the fuselage; four steel cables are connected to the tail ends of the four spring bolt locks, and the four steel cables are respectively connected to one end of a sector wheel fixed on the fuselage. The other end of the first fan-shaped wheel is connected with four steel cables and connected with two pulley blocks, and the pulley blocks are connected on the handle by steel cables. The invention satisfies the emergency opening of hatches in various flight attitudes, is purely mechanical and manual, and is safe and reliable; the principle of the mechanism is simple and clear; and the scheme has strong expansibility.

Description

technical field [0001] The invention belongs to the design technology of an emergency cabin door of an aircraft, and proposes a design scheme of an emergency cabin door for a crew air parachuting. Background technique [0002] For high-speed (greater than 400 kilometers per hour) skydiving of crew members, the method that the main hydraulic system of the aircraft drives the hatch door actuator to open the hatch against the wind as the windshield device is currently used at home and abroad, which belongs to the electronically controlled hydraulic control method. Typical Such as the Il-76 aircraft, this kind of emergency hatch has strict restrictions on skydiving. First, the system is not allowed to fail, which cannot meet the high reliability lifesaving requirements; Straight-line flight, that is to say, is basically limited to the use of the aircraft in the event of a fire that cannot be extinguished. Contents of the invention [0003] Purpose of the present invention: de...

[0002] For high-speed (greater than 400 kilometers per hour) skydiving of crew members, the method that the main hydraulic system of the aircraft drives the hatch door actuator to open the hatch against the wind as the windshield device is currently used at home and abroad, which belongs to the electronically controlled hydraulic control method. Typical Such as the Il-76 aircraft, this kind of emergency hatch has strict restrictions on skydiving. First, the system is not allowed to fail, which cannot meet the high reliability lifesaving requirements; Flying in a straight line, that is to say, basically restricting the use of the aircraft in the event of a fire that cannot be extinguished
