Snowmaker for aircraft testing

Abstract

The invention discloses a snowmaker for aircraft testing, and relates to the technical field of aircraft testing, the snowmaker comprises a snowmaking mechanism, a pitching mechanism, a swing mechanism and a control cabinet, automatic adjustment of the pitching angle of the snowmaker is realized through an electric push rod and a first angular displacement sensor, the control precision of the pitching angle is high, the swing angle of the snowmaker is automatically adjusted by installing a motor, a rotary support, an electromagnetic clutch and a second angular displacement sensor, the swing angle control precision is high, and adjustment is convenient; the electrical control system of the snowmaker is integrally designed with all structures and mechanisms so that the integration degree of the snowmaker is higher; the water nozzle is provided with a plurality of mounting holes so that the spraying amount of water drops can be increased, the snowmaking amount is increased, and meanwhile, the snowfall uniformity is improved.

Description

technical field [0001] The invention relates to the technical field of aircraft testing, in particular to a snowmaking machine for aircraft testing. Background technique [0002] At present, in the process of aircraft development and testing in my country, the field test is used to test and assess the adaptability of the aircraft system to the snowfall environment. However, the environmental conditions of the field test are uncontrollable, which brings difficulties to the operation of test support equipment, test monitoring and measurement equipment, and test personnel. There are many problems and challenges. In order to avoid various difficulties in the field test and ensure that the snowfall environmental conditions are met, the aircraft snowfall test can be carried out in the laboratory. [0003] The aircraft snowfall test in the aircraft climate laboratory simulates the snowfall environment through artificial snowfall, which is not restricted by region and season. Compare...

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
