Method for omnidirectionally preventing flying bird from collision of turbine jet plane

Abstract

The invention relates to a method for avoiding bird to impact turbine injection plane, wherein it fixes anti-impact metal frame at the front air inlet of plane; the metal frame has not lower parameters than the plane; its appearance is taper; when landing and starting, the blades of turbine engine rotate in high speed, the metal frame can confirm enough airflow and avoid bird into engine. The invention has taper shape to reduce the air resistance.

Description

Technical field

[0001] The invention relates to a turbojet aircraft, in particular to a method for preventing airborne birds from colliding and inhaling the turbojet power machine turbojet of the aircraft. Background technique

[0002] The gas turbine propeller used by jet aircraft, the impeller of the turbine engine of the propeller rotates at high speed during take-off and flight to generate a strong negative pressure, and a high-speed intake airflow is formed at the air inlet at the front end of the turbine engine, which has a strong impact on the oncoming birds The strong suction force will impact the turbine engine once the birds inhale it, causing damage to the blades of the turbine engine, engine flameout and other mechanical accidents. It is certain that the air intake at the front end of the turbine engine is the most critical and weak point in a bird strike.

[0003] Since the birth of jet aircraft, the accidents caused by birds hitting aircraft turbine engines ha...

Examples

Embodiment Construction

[0012] Due to the large number of jet aircraft models, the position of the gas turbine propeller is different for each type of aircraft, and the shape of the air inlet at the front end of each propeller is different. The specific implementation needs to be based on the location of the gas turbine propeller of the jet aircraft. The position and the shape of the air inlet at the front end of the propeller determine the shape of the metal mesh cover. Airplanes with compact inlets on the left, right or below the fuselage can be fixed with trapezoidal metal grilles installed at the air inlets at the front of the fuselage and propellers. The technical indicators of the material used for the metal mesh cover must not be lower than the requirements for the surface metal of the aircraft itself. The conical metal mesh cover has more than 2 times the ventilation area and will not reduce the air circulation area; the metal mesh cover is conical or trapezoidal semi-conical streamlined acco...
