A kind of adaptive Inertia particle separator
Technical field
The present invention relates to helicopter manufacturing technology field, especially a kind of adaptive Inertia particle separator.
Background technology
Helicopter has the characteristics that maneuverability, good concealment, survival ability are strong, can undertake other vehicles and be difficult to very To being irrealizable task, irreplaceable effect is all served in military combat, domestic life.For example helicopter can With on extemporal place, mountain area or desert floor, the tasks such as lifting, transport, rescue or investigation and motivation are performed, 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.
In order to realize foregoing invention purpose, the present invention provides following technical scheme:
A kind of adaptive Inertia particle separator, including shell, runner and cylinder,
The runner is arranged on the enclosure, and the cylinder is installed on the housing, the drive link of the cylinder It is connected through the shell with the flow path wall, the flow path wall is deformable structure.
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.

Position behind the position of runner inner wall and runner outer wall after the deformation of where the dotted line signifies that runner, and control-rod retraction The position of splitter,
Label 12 is the runner outer wall after change in location;Label 13 is the runner inner wall after change in location.
Embodiment
The present invention will be described in detail below in conjunction with the accompanying drawings, and the description of this part is only exemplary and explanatory, should not There is any restriction effect to protection scope of the present invention.
A kind of adaptive Inertia particle separator as Figure 1-3, including shell, runner 3 and cylinder,
Runner 3 is set inside the housing, and flow path wall edge is fixedly connected with shell, and other positions separate with shell, Cylinder is arranged on shell, and the drive link of cylinder is connected through shell with flow path wall, and flow path wall is deformable structure, can be flexibility Structure, it can be made up of deformable material.
Flow path wall includes runner inner wall 7 and runner outer wall 2 and is runner 3, runner inner wall 7 and runner outer wall 2 therebetween It is oppositely arranged in shell, runner inner wall 7 is connected with the first cylinder 8, and runner outer wall 2 is connected with the second cylinder 4.
