Circular cross-section door opening design method of embedded compartment

Abstract

The invention belongs to the technical field of aircrafts, and in particular relates to a circular cross-section door opening design method of an embedded compartment. The method is characterized in that the section of a door of the embedded compartment is designed into a circular cross-section, and the door is opened by a sliding manner; a sliding device is arranged at a part in which the door is connected with the embedded compartment; the door moves along an arranged track of the sliding device, and the whole movement is under the driving of a driving mechanism; a single door or two doors can be designed for the embedded compartment according to specific design requirements; when one door is designed and dropping is to be performed, the door slides toward one side until a bomb dropping port is completely exposed; when two doors are designed, the two doors slide toward two opposite sides at the same time until the bomb dropping port is completely exposed; a dropping matter is dropped through a catapult; after the dropping is done, the door/ doors slide in a direction opposite to the previous direction until reaching the original position, and then the embedded compartment is closed. With the adoption of the circular cross-section design method, the precision of the driving mechanism is improved, the total mass is decreased, the mounting is convenient, and the manufacture 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 circular-section inner-buried 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 cha...
