Embodiment Construction

[0031] figure 1 The structure of the simulated ice-shaped article of the present invention is schematically shown. Specifically, the simulated ice-shaped product is a layered structure, which includes an ice-shaped body, an inner layer of glass fiber cloth, an outer layer of glass fiber cloth, and cat litter particles. Wherein, the ice-shaped main body is light in weight and has a certain rigidity, and in order to obtain the same or similar shape as the actual ice-shaped main body, the shape of the ice-shaped main body is preferably processed by a numerical control machine tool. As inner and outer reinforced panels, the materials of the inner layer of glass fiber cloth and the outer layer of glass fiber cloth can not only fit well on the inner surface and outer surface of the ice-shaped main body, but also enhance the surface strength of the ice-shaped main body and enhance the surface strength of the ice-shaped main body. Bond strength between aircraft components. Among the...

Abstract

The invention discloses an installing method of a simulated ice-shaped product. The installing method comprises the following steps of: bonding internal glass fibre cloth on an airplane skin; bonding an ice-shaped main body on the internal glass fibre cloth; and bonding external glass fibre cloth on the outside of the ice-shaped main body so that the external glass fibre cloth can cover the ice-shaped main body completely. The invention can be directly produced on the airplane skin, thus the installing method of the simulated ice-shaped products has multiple advantages of high cementing intensity and good quality stability; and as the selected materials are regular materials, the installing method also has the advantages of strong operability, short construction period, reduced test cost and on the like. The cat litter is pasted on the simulated ice-shaped outer layer to simulate the rough degree of the actual ice shape.

Description

technical field [0001] The invention relates to the field of flight test of civil aviation aircraft, in particular, to the field of flight test of aircraft with simulated ice-shaped products, wherein the flight test of aircraft with simulated ice-shaped products is an indispensable and important link in the process of civil aviation aircraft test flight certification. Background technique [0002] Since the 1980s, a series of icing flight accidents have presented new challenges to anti-icing design. The problem of flight icing has once again become the focus of attention of aircraft manufacturers and airworthiness departments. This is not only due to market pressures that require flights to fly on time regardless of weather conditions, but more importantly because the application of proven new aerodynamic design techniques brings new safety hazards. FAA statistics show that for every 100 flights, there will be 2 icing flights. [0003] my country's Yun-7 aircraft has alrea...
