Method for assembling forming of cockpit glass and cockpit special-shaped opening frame of aircraft

Abstract

The invention belongs to a method for assembling forming of cockpit glass and a cockpit special-shaped opening frame of an aircraft. The method is mainly used for process control over replacing and mounting of brand-new cockpit glass in the overhauling process of the aircraft. Through statistic analysis of cockpit opening frame technical states at different rebuilding intervals and research on theheating tempering compensation size and appearance of aerial organic glass with different shapes and different thicknesses, a 'personalized' assembling forming technological method of the glass in the overhauling process of the aircraft and demands suitable for the 'personalized' assembling forming technological method are determined, and the problems of potential safety hazards of poor cockpit sealing effect, glass stress assembly and the like existing in overhauling of the aircraft for a long term are solved; and the method is low in basic input, technological method and process control iseasy, and the method has great application and popularization value in overhauling of all types of military and civil aviation aircrafts.

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.
