Abstract

The invention provides a double-bent-section and semi-blocking type cargo space door of a civil airplane. The double-bent-section and semi-blocking type cargo space door of the civil airplane has the structure as follows: a handle shaft in a cargo space door is connected with an outer handle mechanism; a ventilation opening mechanism is linked with a handle shaft; locking mechanisms are arranged at the left and right ends of the handle shaft; each locking mechanism is provided with a visual investigation mechanism capable of checking a rotary position of the handle shaft; the handle shaft is linked with a latch shaft; latch mechanisms are arranged at the two ends of the latch shaft; the handle shaft is further linked with an opening mechanism; the opening mechanism comprises a crank II hinged to the cargo space door and an opening mechanism connecting rod connected with a suspension arm; and the cargo space door is linked to do up and down movement relative to a machine body structure. The cargo space door is at a convergence section of the machine body, is a double-bent-section cargo space door and has the advantages of high safety, strong operability and high commonality.

Description

technical field [0001] The invention relates to a cargo compartment door of a civil aircraft, in particular to a large-opening semi-blocking hazardous cargo compartment door located in a hyperbolic section of the fuselage, which is applied to a civil aircraft. Background technique [0002] Civil aircraft doors can be divided into two types: blocked doors and non-blocked doors. Among them, the blocked hatch is divided into full blocked and half blocked hatch. [0003] The initial movement direction of the fully blocked cargo door is inward relative to the average pressure plane. After opening, the door structure is inside the fuselage. After being fully opened, it occupies the cabin space and has a great impact on the net opening. It has been adopted in the design of civil aircraft cargo doors today. Rarely used. The initial movement direction of the non-blocking door is outward relative to the average pressure plane, and the reliability and safety are not high. In addition...
