Entrance be referred to as air inlet 1.As shown in Figure 1：During heating, high temperature and high pressure gas injection external world cryogenic gas that engine attracts
Enter from air inlet；During ventilation, drawing fan sucks outside air from air inlet.
During the flight of helicopter rainy day, if environmental control system work, raindrop under the action of drawing fan 3 or injector 2,
From air inlet it can enter environmental control system distribution circuit with ambient atmos, hence into cockpit.As shown in Figure 2：Environmental control system
Louvered water fender can be generally set outside air inlet；Or extend air inlet, and intensive mesh is opened up in air inlet bottom, when
When ambient atmosphere flows through air inlet, rainwater is fallen under gravity into mesh, flows out air inlet.
However, setting louvered water fender can dramatically increase the inspiratory resistance of fan or the injection resistance of high-pressure bleed air,
So that inlet gas flow rate reduces.Meanwhile water fender grid is hit into the air-flow of air inlet, generate impact noise.And it uses
The extended mode of air inlet can be increased into system occupied space and weight, mesh also easily blocks, and needs frequent cleaning.

It is aspirated through drawing fan, described device sucks the air of air, when rainwater is collided at the arc transition of air inlet pipe, gathers
It is flowed out after collection from funnel.
Preferably, the annular slotted is arranged on the lowest part of air inlet pipe installation condition.
Preferably, the air inlet pipe, funnel and air outlet pipe use unitary design.
Preferably, the air inlet center line of the air inlet pipe and the center line of its gas outlet have angle, and angle is more than
90 ° and less than 180 °.
Preferably, the gas outlet is provided with flange, is connect by flange with the drawing fan.
The advantageous effect of technical solutions of the utility model：Rainwater is with extraneous big when the utility model can prevent rainy day flight
Gas enters helicopter environmental control system pipeline, and effectively quickly raindrop are detached and collected from inlet air flow in shorter stroke, and
The fan and injector resistance of environmental control system will not be impacted, have it is simple in structure, light weight, it is small the features such as.
