Debugging and distance measuring device for emergency lock system of aircraft canopy

Abstract

The invention discloses a debugging and distance measuring device for an emergency lock system of an aircraft canopy, relates to the technical field of aviation equipment, and can effectively measure the center distance between an emergency lock and a transmission mechanism, determine the length size of a pull rod, manufacture the pull rod with the required size, ensure the unlocking stroke of the emergency lock and other main technical parameters. And normal work of the emergency lock system is ensured. The debugging and distance measuring device comprises a fixing head, a distance measuring head, a threaded rod with a notch, a locking nut and scale marks. The end of the fixing head is fixedly connected with the emergency lock; the middle part of the fixed head is a rod with a square section; and the root part of the fixed head is fixedly connected with the notched screw rod. The end of the distance measuring head is fixedly connected with the transmission mechanism; and the middle part of the distance measuring head is a rod with a square section. The threaded rod with the notch and the distance measuring head are integrally machined and manufactured, and a plane is formed at the notch and used for manufacturing scale marks. The locking nut is a hexagonal nut and is installed on the screw rod with the notch, and the measured size is locked after the distance is measured in place.

Description

technical field [0001] The invention relates to the technical field of aviation equipment, in particular to a debugging distance measuring device for an emergency lock system of an aircraft canopy. Background technique [0002] The canopy emergency lock system of the Su-27 series aircraft is an important part of the aircraft ejection life-saving system, which directly determines whether the pilot can be ejected from the aircraft in case of distress in the air and ensures the safety of the pilot's life. [0003] When debugging the emergency lock system, it is necessary to replace the pull rods of different lengths and sizes to ensure that the main technical parameters such as the unlocking stroke of the emergency lock meet the requirements and ensure the debugging requirements of the emergency lock system. [0004] This type of aircraft is a trial repair model of the Air Force equipment system. The aircraft has entered the first overhaul period. There is no measurement plan i...

AI Technical Summary

Problems solved by technology

[0004] This type of aircraft is a trial repair model of the Air Force equipment system. The aircraft has entered the first overhaul period. There is no measurement plan in the system and industry, and it is impossible to accurately measure the center distance between the emergency lock and the transmission mechanism.

[0005] If the center distance between the emergency lock and the transmission mechanism cannot be measured, the debugging of the emergency lock cannot be carried out normally, the canopy of the aircraft cannot be repaired, and the combat effectiveness of the Air Force cannot be guaranteed.
