Problems solved by technology

In this method, due to the complex internal structure of the hatch cover skeleton and the large internal cavity, the flow resistance and flow loss are large when the airflow passes through, and the flow and velocity of the defogging gas finally ejected from the terminal defogging nozzle are greatly reduced. Fog effects are slow and inefficient

Abstract

The invention provides a movable connecting structure of a military aircraft canopy demisting pipeline. The movable connecting structure comprises a crimping head (1), a cover ring (2), a cushion block (3) and a bowl-shaped piece (4), wherein the crimping head (1) is designed at the outlet end of an outlet pipeline (5), the bowl-shaped piece (4) is installed at the inlet end of an inlet pipeline (7), a square structure is sealed with the crimping head (1) in an attached mode, a bowl-shaped structure is arranged in the middle of the square structure, and the cover ring (2) and the cushion block(3) are arranged in the bowl-shaped structure. The designed movable connection structure of the military aircraft canopy demisting pipeline can be used for pipeline air supply connection on a motionstructure, is convenient to manufacture and install, can be applied to pipeline air supply connection on a motion structure in a tandem aircraft cabin, and is reliable in connection and good in sealing performance.

Description

technical field [0001] The invention belongs to the field of mechanical design, in particular to a structure applied to the movable connection of defogging pipelines of canopy covers of military aircraft. Background technique [0002] The cockpit of military aircraft generally adopts a tandem layout, and the hatch cover needs to be designed to open to the right or upward. During flight, the hatch glass is prone to fogging due to the large temperature difference between the inside and outside of the cockpit, so a defogging pipeline is arranged in the aircraft environmental control system. [0003] At present, the demisting air supply pipeline of the aircraft hatch cover is provided with a plurality of demisting nozzles on the hatch cover frame by means of the aircraft hatch cover frame, and the gas of the main demisting pipeline is directly passed into the hatch cover frame. In this method, due to the complex internal structure of the hatch cover skeleton and the large inter...
