Embodiment Construction

[0019] figure 1 It is a dedicated microwave power source of the present invention. The controllable autotransformer B1 provides the anode voltage of the magnetron M after bridge rectification, and the transformer B2 provides the filament voltage of the magnetron M. The control circuit consists of a time relay J SA 、J SS , composed of button switch K and foot switch TK. It has an automatic protection function: that is, J SA Provide magnetron M high-voltage time-delay protection; and J SS Provide magnetron M adjustable time-delay circuit breaker protection, which controls the working time of magnetron M, and is prompted by buzzer FM with sound signal. The magnetron M is the core component, and the frequency of microwave radiation is determined by it. In order to facilitate field repair, a continuous microwave oscillator with a transmission power of 200W and an operating frequency of 2450MHZ is used. Or 915MHZ, when it is less than 200W, the coaxial cable output is used, whe...

Abstract

The present invention relates to the repair of damaged aircraft structure and first aid repair of war damage technology. The fast repair apparatus includes one microwave power source comprising controllable autotransformer, rectifier circuit, control circuit and magnetron and one microwave applying unit comprising converter, coaxial cable and radiation antenna. The fast repair apparatus can heat the damaged part of aircraft in very short time and has no effect on the peripheral parts, so as to repair the damaged part fast and effectively.

Description

technical field [0001] The aircraft structure damage composite material microwave rapid repair technology and equipment of the invention belong to the aircraft structure damage repair and war damage emergency repair technology. Background technique [0002] Due to stress corrosion and fatigue, as well as the impact of foreign objects, cracks and damage are prone to occur on active metal aircraft. At present, the commonly used repair methods in China's outfield are to replace the damaged structure or use metal reinforcement plates to rivet, weld or glue to the damaged part. The disadvantage of this traditional repair method that has been used for many years is that the weight of the structure is increased and the connection efficiency is greatly reduced. When screwing or riveting is used, a new stress concentration area will be formed, and it is difficult to achieve effective repair of the damaged structure. The more serious disadvantages are that the repairing operation...
