Abstract

The invention discloses an aircraft mechanical and electrical integrated large-area flexible impact monitoring intelligent skin system and belongs to the technical field of aerospace intelligent structures. The aircraft mechanical and electrical integrated large-area flexible impact monitoring intelligent skin system comprises an integrated large-area flexible impact monitoring network system andan aircraft composite material skin structure. The integrated large-area flexible impact monitoring network system comprises a large-area flexible piezoelectric sensor network and a large-area flexible impact monitoring system which are sequentially connected and integrally designed and manufactured through a flexible circuit manufacturing technology. The large-area flexible impact monitoring network system and the aircraft composite material skin structure are integrally connected through a vacuum-thermocuring conformal coupling technology to form the mechanical and electrical integrated intelligent skin system. The aircraft mechanical and electrical integrated large-area flexible impact monitoring intelligent skin system can conduct impact monitoring on a large-area aircraft composite material structure in online and continuous modes, has the characteristics of flexibility, integration, lightweight, low power consumption and self-powering allowance, and can improve the safety and maintaining efficiency of an aircraft structure.

Description

technical field [0001] The invention relates to an intelligent skin system for large-area flexible impact monitoring of aircraft electromechanical integration, which belongs to the technical field of aerospace intelligent structures. Background technique [0002] Aircraft intelligent skin technology is a revolutionary new technology that will change the design of advanced aircraft in the future. It can greatly improve the combat flight speed, operational maneuverability, environmental perception performance and safety maintenance performance of advanced aircraft such as advanced fighter jets and unmanned combat aircraft. Reduce the number of combat take-offs and landings, extend the time in the air, and expand the combat radius. At the same time, my country is vigorously developing various types of manned spacecraft, and its environmental perception and safety performance in orbit and deep space flight also urgently need to be guaranteed by increasing the intelligence of the...
