Problems solved by technology

[0005] At present, the rain simulation device is usually a dedicated rain laboratory, and the spray device and water supply pipeline are mostly integrated and fixed, and the rainfall intensity is a fixed value or the adjustment range is small, which is not suitable for the rain test requirements of large equipment; therefore , the design of the existing rain simulation device cannot be fully applied to the rain test of the large-scale comprehensive climate environment laboratory, it is necessary to design a modular rain simulation system to solve the above problems

Embodiment 1

[0078] Such as figure 1 and 2 Shown is a rain test system for aircraft testing, including: a water supply system, a water distribution system, a sprinkler system, a rain collection system, and a water return system;

[0079] The water supply system includes the first pool for storing water in the rain test, the water supply pump and pressure tank for water supply, and the metal filter for filtering the water in the rain test; The water supply pump is combined with the small flow pressure tank for water supply; the filtration accuracy of the metal filter is 100 mesh / square inch;

[0080] The water distribution system includes a first water divider for primary water division of the rain test water in the first pool, and multiple sets of second water dividers for secondary water division of each branch of the first water divider. The water outlet of each first water separator is equipped with an electric regulating valve for adjusting the water supply flow of the second water s...

Embodiment 2

[0087] This embodiment is basically the same as Embodiment 1, the difference is that, as Figure 5-8 As shown, the spray rack of the spray system adopts the folding spray rack 4, the water supply pipeline adopts the second water supply pipe 5 and the third water supply pipe 6, and the nozzle adopts the rotating nozzle 7;

[0088] Such as Figure 5-8 As shown, the foldable shower frame 4 includes a first frame body 41 for carrying four sets of second water supply pipes 5, and a second frame body 42 for carrying four groups of third water supply pipes 6. The first frame body 41 1. The second frame body 42 is an aluminum alloy frame composed of aluminum alloy rods arranged horizontally and vertically. Each aluminum alloy rod at the junction of the first frame body 41 and the second frame body 42 is provided with a bar magnet 44 for docking and positioning by means of magnetic attraction; through the setting of the bar magnet 44, the first frame can be optimized The operation ex...

Abstract

The invention discloses a rain test system for aviation aircraft testing, and belongs to the technical field of aircraft testing. The rain test system comprises a water supply system, a water distribution system, a spraying system, a rainfall acquisition system and a water return system. The water supply system comprises a first water tank, a water supply pump, an air pressure tank and a metal filter; the water distribution system comprises a first water segregator and a second water segregator; the spraying system comprises a plurality of groups of spraying frames, and the plurality of groups of spraying frames are spliced according to a spraying surface to form the spraying system; the rainfall acquisition system comprises a rainfall sensor, a control cabinet and an upper computer; and the water return system comprises a second water tank, a vertical net basket filter and automatic dosing equipment. A unit modular design is adopted, full coverage of an aviation aircraft rain test can be achieved through splicing of the spraying frames of the spraying system according to the specific appearance of an aviation aircraft, and mounting, dismounting and transportation are easy.

Description

technical field [0001] The invention relates to the technical field of aircraft testing, in particular to a rain test system for aviation aircraft testing. Background technique [0002] In the aviation aircraft test engineering, the flight missions to be completed by the aircraft and its characteristics determine the characteristics of the test: ① Aircraft test is closely related to modern advanced science and technology: for example, supersonic wind tunnel experiment technology and holographic technology in the air of aircraft It has been widely used in dynamic tests; ②The scale and cost of the test are huge, the preparation time is long, and the test area is wide: for example, driving a continuous supersonic wind tunnel with a Mach number greater than 10 and a test section with a diameter of 2 to 3 meters requires consumption The power of the first space shuttle is as high as 160,000 kilowatts, and the first space shuttle has carried out a total of about 100,000 hours of w...
