Airplane surface temperature detection system

Abstract

The invention discloses an airplane surface temperature detection system and belongs to the airplane temperature detection technology field. The airplane surface temperature detection system comprises a sheath, a single-mode fiber, a multi-mode fiber, a hollow tube, a laser device and a photoelectric coupler, wherein one end of the single-mode fiber is connected with the laser device, one end of the multi-mode fiber is connected with the photoelectric coupler, the hollow tube is embedded in the sheath, the other end of the single-mode fiber and the other end of the multi-mode fiber are arranged in the hollow tube, end faces of the single-mode fiber and of the multi-mode fiber and the hollow tube form an enclosed chamber, the end faces of the single-mode fiber and of the multi-mode fiber are in parallel with each other in the enclosed chamber, the end faces are bonded with high reflection films, and light signals emitted by the laser device pass through the single-mode fiber, then pass through the enclosed chamber and pass through the multi-mode fiber to enter the photoelectric coupler. The airplane surface temperature detection system is advantaged in that weight of an aircraft can be reduced, the space is saved, design is simplified, and stealth and anti-electromagnetic interference of an airplane are facilitated.

Description

technical field [0001] The invention relates to the technical field of aircraft temperature detection, in particular to an aircraft surface temperature detection system. Background technique [0002] In the traditional design concept, the skin is only a structural structure that meets the requirements of aerodynamics and strength. When it is necessary to install sensors to measure the surface temperature, holes are drilled in the skin, which brings unnecessary structural and other losses, and the integration level is low. [0003] Future wars will become increasingly complex and changeable, the multi-dimensional battlefield environment will become increasingly severe and interpenetrating, and the requirements for the survivability of weapons and equipment will become higher and higher; on the other hand, the design of military aircraft will become increasingly complex, integrated, multi-functional and multi-purpose. These two pose considerable challenges to the design of air...
