Ask close to ground hovering, take-off and landing, can also hover and fly on sea again.For this reason, helicopter just has
Serious more environmental impact issues than other types aircraft.
Aboard, engine is a component that is extremely important and being easily damaged, it is necessary to prevents hostile environment to it
Infringement.In various environmental effects, Sand Dust Environment is an environmental factor that can not ignore.It is general to regard 0.01mm ~ 1.0mm's
Particle is sand, and 0.0001mm ~ 0.01mm particle is dust.Dirt sand swallows caused main disastrous effect by engine:Pressure
Mechanism of qi blade is denuded and resulting engine performance deterioration, i.e. power drop, rate of fuel consumption increase, ultimately results in engine
Service life shortens.Therefore, various purification air inlets are widely used on helicopter, such as filter, barrier particle separator, rotation
Wind particle separator, tubular type particle separator, Inertia particle separator etc..Wherein, Inertia particle separator is due to the letter of its structure
The advantages that single, in light weight, flow losses are small, it is usually used in high velocity air feeder connection.
When flow channel of the fluid containing solid particles of sand by turn, particle is due to its inertia, always from bending
The position centrifugation movement of the passage center of curvature(Or moved by original rectilinear direction).In this way it is possible to streamline of jumping over, point
The dirt sand powder collection being dispersed in fluid gets up and excluded from system.
The size range for the particle that can be isolated is a highly important parameter of Inertia particle separator, and it is very
The scope that helicopter performs task is have impact in big degree.Several Inertia particle separator inner flow passage shapes main at present are all
Be fixed, only there is preferable separating effect to the dirt sand of specific dimensions scope, and in reality different geographical dirt sand particle chi
Very little difference, even the dirt sand in same place also has different Size Distributions, this adaptability to Inertia particle separator carries
Very high requirement is gone out.
The content of the invention
The present invention in view of the shortcomings of the prior art, proposes a kind of adaptive Inertia particle separator, can be according to different rings
Various sizes of dirt sand particle adjustment flow channel shape under border, improves the adaptability of helicopter, extends helicopter and perform task
Scope.

Further, the flow path wall includes runner inner wall and runner outer wall and is runner therebetween, in the runner
Wall is oppositely arranged in the shell with the runner outer wall, and the runner inner wall is connected with the first cylinder, the runner outer wall
It is connected with the second cylinder.
Further, first cylinder is interleaved in the direction that the flow channel length extends with second cylinder
's.
Further, the big convex radian of half portion thereon of the recessed radian in the shell lower half,
The runner outer wall and second cylinder are arranged on the shell first half, and the runner outer wall is convex
Its shape is corresponding with the shell first half shape when playing highest point,
The runner inner wall and first cylinder are arranged on the shell lower half, and the runner inner wall is to recessed
Enter corresponding with shell lower half shape to its shape during lowest part.
Further, in addition to control-rod and splitter,
The splitter and the control-rod are located in the runner, and the control-rod is extension type and grown along the runner
Direction extension is spent, the splitter is arranged on the control-rod close to the position of the air inlet of the runner.
Further, the tip of the splitter cross section is close to the air inlet side, and the splitter is close to the runner
Outer wall is arcwall face for plane, close to the runner inner wall.
A kind of adaptive Inertia particle separator of the present invention, it can be adjusted according to various sizes of dirt sand particle under varying environment
Rectification road shape, the adaptability of helicopter is improved, extend the scope that helicopter performs task.
