Method for assembly and molding of aircraft cockpit glass and cockpit special-shaped mouth frame

Abstract

The invention belongs to a method for forming an aircraft cockpit glass and a special-shaped cockpit frame, and is mainly used for the process control of replacing the new cockpit glass in the process of aircraft overhaul. This invention determines the "personalized" assembly and molding process of the glass during the aircraft overhaul process through the statistical analysis of the technical status of the cockpit frame at different overhaul intervals, and the research on the size and shape of aviation plexiglass with different shapes and thicknesses for heating and tempering compensation. As well as the needs to adapt to it, it solves the long-standing safety hazards such as poor sealing effect of the cockpit and glass stress assembly in the aircraft overhaul. The basic investment is low, the process method and process control are simple, and it has good promotion and application value in the overhaul of various military and civil aviation aircraft.

Description

technical field [0001] The invention relates to a method for assembling and forming an aircraft cockpit glass and a special-shaped cockpit hatch frame deviated from the design technical state. Background technique [0002] Every time the aircraft is used for a period of time, the aircraft body and the cockpit hatch frame will be deformed to varying degrees. The shapes of each cockpit hatch frame are different, and most of them have deviated from the design state. If the cockpit glass produced and formed according to the design drawing is directly installed on the machine, there must be a gap between the glass and the cockpit frame, resulting in the impossibility of sealing the cockpit; forced assembly in order to eliminate the gap will lead to the existence of assembly stress, which can be From a few MPa to more than ten MPa, it will directly affect the reliability and service life of the cockpit glass, and the safety hazard is very serious. [0003] In addition, the deform...

If the cockpit glass produced and formed according to the design drawing is directly installed on the machine, there must be a gap between the glass and the cockpit frame, resulting in the impossibility of sealing the cockpit; forced assembly in order to eliminate the gap will lead to the existence of assembly stress, which can be From a few MPa to more than ten MPa, it will directly affect the reliability and service life of the cockpit glass, and the safety hazard is very large.
