A snowmaking machine for aircraft testing

Abstract

The invention discloses a snowmaking machine for aircraft testing, which relates to the technical field of aircraft testing, including a snowmaking mechanism, a pitching mechanism, a swing mechanism and a control cabinet. The pitching angle of the snowmaking machine is realized by an electric push rod and a first angular displacement sensor. The automatic adjustment of the pitch angle control is high, and the automatic adjustment of the swing angle of the snow machine is realized by installing the motor, slewing support, electromagnetic clutch and the second angular displacement sensor. The control precision of the swing angle is high and the adjustment is convenient; the electrical control of the snow machine The system and various structures and mechanisms adopt an integrated design, and the integration degree of the snow machine is higher; by setting multiple installation holes on the water nozzle, the amount of sprayed water droplets can be increased, thereby increasing the amount of snowmaking and improving the uniformity of snowfall sex.

Description

Technical field [0001] The present invention relates to testing of aircraft technology, and particularly relates to an aircraft test snowmaking machines. Background technique [0002] At present, my country in aircraft development and testing process, through field tests on aircraft snowfall environmental adaptability test examination, but environmental conditions, field trials can not be controlled, to an operating test support equipment, test monitoring and measurement equipment, and test personnel to bring a lot of problems and challenges, in order to avoid the difficulties field trials arise, and to ensure that environmental conditions are met snowfall, snow aircraft can be tested in the laboratory. [0003] Aircraft climate laboratory test is to simulate the aircraft snowfall snowfall environment through artificial snow way, without geographical and seasonal restrictions, compared to the use of natural snowfall tested more convenient and efficient; snowfall test aircraft hav...

Problems solved by technology

[0004] At present, there are similar snowmaking machine solutions on the market: the patent application with the publication number CN208595736U discloses a snowmaking machine, which uses the atomization nozzle and ice source nozzle in the snowmaking cylinder to cooperate with the fan to realize snowmaking, and connects the snowmaking cylinder The hydraulic rod realizes the adjustment of the pitch angle of the snow-making tube; the pitching angle of the snow-making tube of the snow machine is adjusted by manually adjusting the working state of the hydraulic rod up and down, the pitch angle is difficult to adjust quickly, and the control accuracy is low; the snow-making tube It cannot swing left and right, and the snow formed is concentrated in front of the snow-making tube, which cannot simulate uniform snowfall; without anti-freezing measures, nozzles and pipelines are prone to freezing blockage, which affects the development of the test; the patent application with the publication number CN208595736U discloses a cannon The snow-making machine, the support frame of the snow-making part is rotated and installed on the traveling frame through a rotating device, and the snow-making part can be horizontally rotated to the corresponding angle and locked according to the needs of use. The rotating device of the gun-type snow-making machine It is a purely mechanical structure, and the rotation of the snowmaking part can only be adjusted manually. On the one hand, it is difficult to precisely control the rotation angle; The snow gun also has no anti-freeze measures, and the nozzles and pipelines are prone to freeze blockage, which affects the development of the test

[0005] None of the above-mentioned prior art solutions can automatically and accurately control the pitch angle and swing angle of the snow-making tube or snow-making part of the snow-making machine. If used for a long time at low temperature in the laboratory, the nozzle and supporting pipes will be easily blocked by freezing, which will affect the test process
