Problems solved by technology

[0003] During the parking period of the aircraft, in order to prevent foreign objects from entering into the pitot tube and causing blockage of the pitot tube, a protective sleeve is usually used to seal and protect the pitot tube. However, once people forget to remove the protective cover, the pitot tube will not work normally in the future, which will lead to safety accidents

Abstract

The invention provides a self-separation protective sleeve for an airspeed tube of a civil aircraft, and belongs to the technical field of aircraft protection devices. The self-separation protective sleeve comprises a pipeline, a first elastic piece, an extension head, a clamping part and a driving part; an air inlet is formed in the side wall of the pipeline, a spoiler is movably arranged in the air inlet, one end of the first elastic piece is connected with the inner wall of the pipeline, the other end of the extension head is connected with the spoiler and used for providing elastic support for the spoiler, the extension head is fixedly installed at one end of the pipeline and used for being inserted into an airspeed tube, the clamping part is arranged on the outer side of the extension head and used for fixing the extension head into the airspeed tube, and the driving part is movably arranged in the pipeline. Compared with the prior art, the self-separation protective sleeve has the advantages that in the takeoff process of an airplane, automatic separation between the airspeed tube protective sleeve and the airspeed tube can be achieved, potential safety hazards caused by manual negligence are eliminated, and normal work of the airspeed tube is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of aircraft protection devices, in particular to a self-separating protective sleeve for a civil aircraft pitot tube. Background technique [0002] Pitot tubes are also called pitot tubes, total pressure tubes, and total-static pressure tubes. They can sense the total pressure (also called total pressure) and static pressure of the airflow, and transmit the measured pressure data to the air data computer and flight instrument. device. [0003] During the parking period of the aircraft, in order to prevent foreign objects from entering into the pitot tube and causing blockage of the pitot tube, a protective sleeve is usually used to seal and protect the pitot tube. However, once people forget to remove the protective cover, the pitot tube will not work normally in the future, which will lead to safety accidents. Contents of the invention [0004] In view of the above-mentioned deficiencies in the prior ar...
