A design method for the opening of a buried cabin

Abstract

The invention belongs to the technical field of aircrafts, particularly relates to a design method for opening an embedded cabin. The embedded cabin adopts a rotary mount bracket to carry arms and ammunition or throwing objects, and one or a plurality of baffle plates are connected onto a rotary shaft of the rotary mount bracket. When a plurality of baffle plates exist, the throwing objects and the baffle plates are alternatively distributed and are driven by a driving device along with the rotary shaft. The embedded cabin is not provided with a cabin door or a subsystem thereof, and the position of the original cabin door is empty to form a throwing gap. When not in throwing, the baffle plates are arranged above the gap and are sealed through a sealing device, and thereby the integrity of the appearance of the aircraft is maintained. When needing to throw, the rotary shaft rotates, the baffle plates above the gap move off to expose the throwing objects positioned in a window, and the throwing objects are thrown through an ejection device. The flying quality is high. Meanwhile, the design complexity degree of the whole embedded cabin is reduced, the needed parts are also correspondingly decreased, the precision is improved, the total weight of the embedded cabin is reduced, and the manufacturing cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of aircraft, and in particular relates to a design method for opening a built-in cabin. Background technique [0002] There are many military and civilian aircrafts that need built-in compartments to load weapons, ammunition or projectiles. [0003] There are two main ways for the aircraft to load weapons, ammunition or projectiles: the external type and the internal type. The external hanging type is to use the hanger to hang on the lower part of the wing, the lower part of the fuselage and the side of the aircraft; the embedded type is to load all the weapons, ammunition or dropped objects into the interior of the aircraft. [0004] For military aircraft, such as fighter jets, traditionally, the external method is often used to carry weapons and ammunition. At present, many countries in the world have successively started the development of the fourth-generation fighter jets. The characteristics of the n...

Problems solved by technology

[0010] The purpose of the present invention is to propose a simple and reliable built-in hatch door system in order to solve the problem of aerodynamic shape changes caused by the opening of the hatch door of the aircraft and the complex design and multiple parts of the built-in hatch door system. The design method of opening the cabin makes it possible for the aircraft to avoid opening the hatch when the built-in cabin is opened and launched, so as to obtain better flight quality
