Abstract

The invention belongs to the field of wind tunnel tests, and particularly relates to a design parameter control method for transonic flutter wind tunnel model processing. The method comprises the steps that a metal beam frame is adopted for manufacturing an airplane force bearing component, a first flutter wind tunnel model is generated, and a first ground resonance test is conducted on the first flutter wind tunnel model; a balancing weight is adhered to the first flutter wind tunnel model to generate a second flutter wind tunnel model, and a second ground resonance test is performed on the second flutter wind tunnel model; accessories, embedded sensors and pasted foam fillers are mounted on the second flutter wind tunnel model; a composite material skin test piece is obtained, and a material tensile test and a composite material skin test piece resonance test are performed on the composite material skin test piece; a composite material skin is laid in the mold, the second flutter wind tunnel model is put into the composite material skin for medium-temperature curing to generate a third flutter wind tunnel model, and a third ground resonance test is performed on the third flutter wind tunnel model.

Description

technical field [0001] The application belongs to the field of wind tunnel tests, and in particular relates to a design parameter control method for transonic flutter wind tunnel model processing. Background technique [0002] The transonic flutter model test is an effective means to verify the design flutter characteristics and flutter velocity margin of the aircraft in the transonic range. The tests can be used to verify and correct flutter calculation methods used in aircraft flutter calculations and transonic unsteady aerodynamics. The focus of the design of the transonic flutter model is to accurately simulate the dynamic characteristics of the real aircraft structure. Whether the structural dynamics are proportionally similar depends on the mass distribution and the stiffness distribution. Since the transonic model is composed of aluminum alloy metal beam frame, composite material skin and foam filling, it needs to be bonded through multiple medium temperature curing...
