Measuring device for simulated assembly of engine thrust reverser

Abstract

The invention discloses a simulation assembly measuring device for an engine thrust reverser. The device comprises a basic frame, side supports arranged at the two ends of the basic frame, an airplane girder simulation assembly installed at the two ends of the two side supports, an engine nacelle simulation assembly, an engine hood simulation assembly, an air guide hole detection assembly, an airplane hanging simulation assembly and a pre-cooling hole detection assembly, wherein the engine nacelle simulation assembly, the engine hood simulation assembly and the air guide hole detection assembly are installed on the vertical surface of the first side support; the airplane hanging simulation assembly is installed on the lower side of a beam of the airplane girder simulation assembly; the pre-cooling hole detection assembly is arranged on the lower side of the airplane hanging simulation assembly. When the engine thrust reverser is simulated, assembled and measured by means of the simulation assembly measuring device, whether the assembly size and assembly relations of the thrust reverser are qualified can be conveniently detected, and the problem that the thrust reverser can not be detected as a whole is solved.

Description

technical field [0001] The invention belongs to the field of space structure size and assembly relationship measuring instruments, and in particular relates to an assembly size and assembly relationship measuring device of an aircraft engine thrust reverser. Background technique [0002] The aircraft engine thrust reverser is mainly composed of left and right C-shaped petals, and the left and right C-shaped petals are riveted by sheet metal parts, composite parts, machined parts, etc. (attached Figure 8 , attached Figure 9 ). After the assembly is completed, it is necessary to check whether the assembly size and assembly relationship with the engine nacelle, aircraft suspension, engine guard and other related components are correct. Design requirements to ensure that the thrust reverser can be successfully mounted on the aircraft. Since the thrust reverser has the characteristics of complex shape, large diameter, many parts, and easy deformation, its size and assembly re...
