Abstract

The invention relates to an aero-engine nacelle ventilation cooling opening grating angle test device, and the device comprises a ventilation opening pedestal (1) which is provided with a ventilation opening; and the grating plate (3) is mounted in the ventilation opening of the ventilation opening base (1) in an angle-adjustable manner. The grating plate (3) is installed in the ventilation opening of the ventilation opening base (1) in an angle-adjustable mode, the air volume of the ventilation cooling opening of the nacelle can be measured by changing the angle of the grating plate (3) when grating plates with different angles are installed at the ventilation cooling opening of the nacelle, and therefore the problem that in the prior art, cost is high when independent grating exhaust port test pieces with different angles are prepared is solved.

Description

technical field [0001] The invention relates to the field of aero-engines, in particular to an aero-engine nacelle ventilation cooling opening grid angle test device. Background technique [0002] The engine nacelle includes an air inlet, a fan cover and a thrust reverser component, wherein the fan cover and the engine form a fan cabin. Various accessories and flammable liquid pipelines are arranged in the fan compartment. When the engine is running, the accessories will transfer a lot of heat into the fan compartment. If the heat cannot be dissipated in time, it will cause the temperature in the cabin to rise sharply, making the accessories unable to work normally; at the same time, when the liquid pipeline in the nacelle leaks, the liquid will form flammable vapor under the action of high temperature. Start a fire. Therefore, it is necessary to carry out ventilation and cooling design for the fan compartment of the power unit. On the one hand, the nacelle ventilation a...
