Embodiment 1

[0038] Such as figure 1 As shown, a snowfall environment simulation system for aviation aircraft testing includes an experimental cabin 1 for accommodating aviation aircraft, 4 groups of snowmaking machines 2 located at 4 corners inside the experimental cabin 1, and in front of each group of snowmaking machines 2. The diversion barrier 3, the snow machine 2 is a commercially available ESB-A8 snow machine;

[0039] Such as Figure 1-5As shown, the front end of the snowmaking machine 2 is provided with a movable nozzle 21, and the diversion barrier 3 is arranged in an arc shape. The middle part of the diversion barrier 3 is provided with an opening 31 corresponding to the front end of the nozzle 21. 31 Rotate and slide the guide cover 4, the guide cover 4 is a cylinder formed by splicing several guide blades 41, the upper and lower sides of the guide cover 4 are respectively provided with a set of limit blocks 42 for fixing the guide blades 41, each set A group of rotating sha...

Embodiment 2

[0050] This embodiment is basically the same as Embodiment 1, except that the sound-absorbing baffle 5 and the diversion barrier 3 are set at an angle of 15°, and the experimental parameters in steps S1 and S2 are different.

[0051] S1: Place the aircraft to be tested in the middle of the experimental cabin 1, and arrange the snow machine 2 around the aircraft. The snow machine 2 should leave a sufficient safe distance from the wall of the experimental cabin 1 and the aircraft. The safe distance is 3m from the snow machine 2 to the wall. And the snow gun 2 is 20m away from the aircraft;

[0052] S2: According to the type of snowfall required, set the target temperature of the experiment to -20°C, and start to cool down at a rate of 3°C / h.

Embodiment 3

[0054] This embodiment is basically the same as Embodiment 1, except that the sound-absorbing baffle 5 and the diversion barrier 3 are set at an angle of 30°, and the experimental parameters in steps S1 and S2 are different.

[0055] S1: Place the aircraft to be tested in the middle of the experimental cabin 1, and arrange the snow machine 2 around the aircraft. The snow machine 2 should leave a sufficient safe distance from the wall of the experimental cabin 1 and the aircraft. The safe distance is 3m from the snow machine 2 to the wall. And the snow gun 2 is 15m away from the aircraft;

[0056] S2: According to the type of snowfall required, set the target temperature of the experiment as 5°C, and start to cool down at a rate of 1°C / h.

[0057] In embodiment 1-3, according to the snowfall temperature condition that the present invention provides and cooling speed select suitable safety distance, when temperature condition is lower, cooling speed is accelerated correspondingl...

Abstract

The invention discloses a snowfall environment simulation system and method for aviation aircraft testing, which belongs to the technical field of aircraft testing. The simulation system includes an experimental cabin for accommodating aviation aircraft, 4 sets of snowmaking machines located at four corners inside the experimental cabin, and The diversion barrier located in front of each group of snow guns, the middle part of the diversion barrier is provided with an opening corresponding to the front end of the nozzle, and the inside of the opening is provided with a diversion cover that can rotate and slide along the opening. Noise-absorbing baffles, and two sets of collection bins for collecting snowflakes are arranged in the middle of the inner surface of the diversion barrier. The simulation methods include: S1 to arrange the system; S2 to adjust the temperature; S3 to adjust the amount of snow; S4 to adjust the water content; S5 to adjust the visibility and snow particle size; S6 to evaluate the snowfall intensity. In the snowfall environment simulation method of the present invention, the snowfall environment parameters are stable and controllable, the environment parameters can be adjusted in a wide range, and the simulation can be repeated, which is not affected by natural conditions and saves experiment costs.

Description

technical field [0001] The invention relates to the technical field of aircraft testing, in particular to a snowfall environment simulation system and method for aviation aircraft testing. Background technique [0002] Aviation is a complex and strategic human activity, which refers to the flight (navigation) of aircraft in the earth's atmosphere (air space). Aviation aircraft is the most common aircraft, occupying an important role in the fields of public transportation, aviation sports, national defense and military affairs. important position. [0003] The testing and research of aviation aircraft has been continuously carried out, and the dedicated climate laboratory is an important prerequisite for carrying out aviation aircraft experiments. The purpose of testing the performance of aviation aircraft is achieved by simulating various climatic and environmental conditions through the dedicated climate laboratory. . [0004] Civil aircraft is the most widely used aircra...
