Description
Technical field
The present invention relates to helicopter manufacturing technology field, especially a kind of self adaptation Inertia particle separator.
Background technology
Helicopter has the features such as maneuverability, good concealment, survival ability be strong, and can undertake other vehicles is difficult to or even irrealizable task, all serves irreplaceable effect in military combat, domestic life.Such as, helicopter on extemporal place, mountain area or desert floor, can perform lifting, transport, rescue or the task such as investigation and motivation, it is desirable to close to ground hovering, take-off and landing, it is also possible to hovering and flight on sea again.For this reason, helicopter just has the many environmental impact issues more serious than other types aircraft.
Aboard, electromotor is a component that is extremely important and that be easily damaged, it is necessary to prevent the hostile environment infringement to it.In various environmental effects, Sand Dust Environment is an environmental factors can not ignore.Being generally sand depending on the particle of 0.01mm ~ 1.0mm, the particle of 0.0001mm ~ 0.01mm is dust.Dirt sand is swallowed the main disastrous effect caused by electromotor: compressor blade abrasion and consequent engine performance deterioration, and namely power drop, rate of fuel consumption increase, and the service life ultimately resulting in electromotor shortens.Therefore, various purification air inlets are widely used on helicopter, such as filter, barrier particle separator, whirlwind particle separator, tubular type particle separator, Inertia particle separator etc..Wherein, Inertia particle separator, due to its simple in construction, the advantage such as lightweight, flow losses are little, is usually used in high velocity air feeder connection.
When the fluid containing solid particles of sand passes through the flow channel turned round, particle is due to its inertia, always centrifugal mobile (or by original rectilinear direction motion) from the position of the bending channel center of curvature.The streamline in this way it is possible to jump over, gets up the dirt sand powder collection being dispersed in fluid exclude from system.
Can the size range of isolated particle be a highly important parameter of Inertia particle separator, it have impact on helicopter to a great extent and performs the scope of task.Several Inertia particle separator inner flow passage shapes currently mainly are all fixing, only the dirt sand of specific dimensions scope there is good separating effect, and the dirt sand particle size of different geographical is different in reality, even the dirt sand in same place also has different distribution of sizes, the adaptive capacity of Inertia particle separator is proposed significantly high requirement by this.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is proposed to a kind of self adaptation Inertia particle separator, it is possible to adjust flow channel shape according to various sizes of dirt sand granule under varying environment, improve the adaptability of helicopter, extend helicopter and perform the scope of task.
In order to realize foregoing invention purpose, the present invention provides techniques below scheme:
