Problems solved by technology

Through the above analysis, the design of the existing rain simulation device cannot be fully applied to the rain test in a large-scale comprehensive climate and environment laboratory. Therefore, it is necessary to design a modular rain simulation device that not only meets the parameters of the rain test in the climate and environment laboratory, but also And it can achieve a wide range of rainfall intensities, and it is easy to install and disassemble

Abstract

The invention discloses an aircraft test rain simulation device and a simulation method, belonging to the technical field of aircraft testing, comprising a modular spray frame, a plurality of water supply pipelines arranged on the modular spray frame, and a fixed water supply pipeline. Multiple pipe clamps for the pipeline, nozzles on the water supply pipeline, and balanced lifting points for hoisting the modular spray rack; in order to meet the requirements of the aircraft climate and environment laboratory, the spraying area is large, and it is easy to disassemble and install. Requirements, the present invention carries out two different modular designs to the rain simulation device. The advantage of the modular design is that it can be spliced ​​and combined according to the structural shape of the test object, and it is convenient for installation, disassembly and transportation; the present invention adopts four different The nozzles of the model are composed of seven different combinations. On the premise of not replacing the nozzles, it can realize the adjustment of the continuous rainfall intensity in a wide range and avoid the interruption of the rain test.

Description

technical field [0001] The invention relates to the technical field of aircraft testing, in particular to an aircraft test rain simulation device and a simulation method. Background technique [0002] The rain test of aviation aircraft usually uses a climate environment laboratory that can simulate various climate environments to simulate the rain environment. The climate environment laboratory means that various climate environments can be simulated in the laboratory, and the rain environment is a simulated environment. one. [0003] The rain simulation device cannot be designed in a fixed form in the laboratory, otherwise the device will also have to withstand other harsh climatic environments when the rain test is not performed, the technical difficulty will increase, and the development cost will increase. Therefore, the rain simulation device should be designed It is portable, easy to disassemble and transport. The object of the rain test in the climate and environmen...
