Airplane surface pressure detection system

Abstract

The invention discloses an airplane surface pressure detection system and belongs to the airplane pressure detection technology field. The airplane surface pressure detection system comprises a sheath, a fiber, a sensitive diaphragm, a photoelectric coupler, a laser device, a wavelength division multiplexer and a demultiplexer, wherein the sheath comprises an outer sheath and an inner sheath, the sensitive diaphragm is arranged between the outer sheath and the inner sheath, a reflection chamber is arranged between a side face of the sensitive diaphragm close to the inner sheath and the inner sheath, one end of the fiber is connected with the laser device, the other end is connected with the photoelectric coupler, multiple branch fibers are arranged between two ends of the fiber, the other ends of the branch fibers correspond to the reflection chamber, end faces of the branch fibers corresponding to the reflection chamber are plated with reflection layers, the wavelength division multiplexer is arranged at an output end of the laser device, and the demultiplexer is arranged at an input end of the photoelectric coupler. The system is advantaged in that weight reduction of an aircraft can be facilitated, 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 pressure detection, in particular to an aircraft surface pressure 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 sensors need to be added, 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 weapon platforms with limited space, and the emerg...
