Problems solved by technology
At present, there are two ground test methods for aircraft windshield and wiper systems: rain and wind tunnel, which can simulate a more realistic natural climate environment, but due to the limitations of the size of the wind tunnel and auxiliary equipment, only component-level windshield and wiper tests can be carried out, making The working platform of the windshield and wiper lacks authenticity; the outdoor rain test is adopted, and the extreme weather environment with mixed wind and rain is limited by season, region and time, which makes the test period long and the cost increases

The invention discloses a wind tunnel comprising an inlet section, a power section, a transition section, an equal-straight section, and a contraction section which are sequentially connected to eachother. Four single wind turbine power sections arranged in two rows and two columns are arranged in the power section; a gas collection section, a first cowl, a motor, a second cowl, and a third cowlare sequentially arranged on each single wind turbine power section along an air inlet direction; the gas collection section is in a bell mouth shape, and is arranged at the air inlet of the single wind turbine power sections; the inner wall of the single wind turbine power sections are connected to the first cowl through a supporting piece; blades are connected to the output shaft of a motor; andthe inner wall of the single wind turbine power sections are connected to the second cowl through a rotation stopping piece. According to the wind tunnel and the wind tunnel test device, the wind tunnel and wind tunnel test system are not limited by seasons, regions and time; the test period is short and the cost is low; the climate environment conditions can be accurately controlled; the test can be performed repeatedly; and the test result is reliable.
Description
technical field [0001] The invention belongs to the technical field of fluid mechanics, and in particular relates to a wind tunnel and a wind tunnel test system. Background technique [0002] In the prior art, it is required to carry out ground test verification for the function and performance of the rain and snow removal equipment in the windshield area of the aircraft. At present, there are two ground test methods for aircraft windshield and wiper systems: rain and wind tunnel, which can simulate a more realistic natural climate environment, but due to the limitations of the size of the wind tunnel and auxiliary equipment, only component-level windshield and wiper tests can be carried out, making The working platform of the windshield wiper lacks authenticity; the outdoor rain test is adopted, and the extreme climate environment with mixed wind and rain is limited by season, region and time, which makes the test period long and the cost increases. [0003] Therefore, a...
