Aerating device for pitot

Abstract

The invention discloses an aerating device for an pitot. The aerating device mainly comprises a total pressure connecting pipe, a middle end cover, a static pressure connecting pipe, an end cover and a sealing component. The aerating device is characterized in that air current is injected from the outside to compress the sealing component in the static pressure connecting pipe, and a rubber part of the sealing component is enabled to deform, thereby plugging the pitot needing to be tested, preventing circumferential rotation of the pitot, overcoming an acting force applied in the axial direction of the pitot, preventing axial drifting of the pitot, reducing unstable factors in the aerating process of the pitot, and facilitating the improvement on performance detection precision of relevant sensors inside the pitot and convenience and quickness of actual operation. According to the aerating device for the pitot, disclosed by the invention, a segmented adjustable structure can be realized; compared with a traditional aerating device, the aerating device disclosed by the invention has the advantages that the defects of being heavy in handling and tedious in operation and long time for replacing testing parts, and the like of the aerating device are overcome; the aerating device also has the advantages of good sealing effect, light weight, convenience in carrying and operation, high working efficiency and the like, and can adapt to multiple operation environments.

Description

technical field [0001] The invention belongs to the field of aviation devices, and more specifically relates to a pitot tube refueling device. Background technique [0002] The pitot tube is also called the Pitot tube, the total pressure tube, and the total-static pressure tube. It is a device that senses the total pressure (also known as total pressure) and static pressure of the airflow, and transmits the measured pressure data to the air data computer and flight instrument. This aviation device is mainly used to measure flight speed, but also has many other functions. When the aircraft is flying forward, the airflow rushes into the pitot tube, and the sensor at the end of the tube will sense the impact force of the airflow, that is, the dynamic pressure. The faster the plane flies, the greater the dynamic pressure. If you compare the pressure when the air is still, that is, the static pressure and the dynamic pressure, you can know how fast the air is rushing in, that ...
