Description
Technical field:
The present invention relates to a kind of protective housing that is used to protect turbofan engine of aeroplane safety; it comprises that is installed in the housing that motor head is used for stopping rammer; be arranged on and be used for the gas port of conducting air above the housing; be arranged on shell end and be used for the fixing belt that is connected with motor; be arranged on the keyhole above the fixing belt, be arranged on and be used for the supporting frame of support housing in the housing.
Background technique:
Motor is the vitals of aircraft, and it provides flying power for aircraft, and its running state is vital to aircraft and personal safety.Bump owing to aerial rammer causes the accident of motor damage to happen occasionally for many years, as: the birds of flight, hail etc., its consequence is very serious.Analyze from the aircaft configuration aspect, take precautions against in the place ahead of motor is the weakest, and rammer can directly enter motor, damages the parts of motor, causes engine running unusual or shut down.If set about from this book weakness, install protective housing additional at the front end of motor, allow it bear bump and stop rammer, make rammer change movement angle, thus the protection motor, it is little and the function of sufficient air is provided for motor to make it possess resistance of air simultaneously.Increased resistance and the fuselage weight of aircraft though install protective housing additional, considered, installed protective housing additional and be very important from the angle of flight safety and personal safety to air.Below protective housing is elaborated.
Summary of the invention:
The technical problem to be solved in the present invention provides a kind of protective housing that is used to protect turbofan engine of aeroplane; it can stop to the sudden rammer of motor head; such as: aloft birds, hail; it can make rammer just change moving direction before the bump motor; thereby avoided the damage of rammer to airplane engine, the engine health running has had assurance.Though install protective housing increased aircraft resistance of air and. fuselage weight, consider that from the security standpoint of the aircraft and the person installation protective housing is very important.This protective housing only is applicable to turbofan engine.
For this reason; the invention provides a kind of protective housing of protecting turbofan engine of aeroplane safety; it comprises that is installed in the housing that motor head is used for protecting engine health; one is arranged on and is used for the gas port of conducting air above the housing; one is arranged on shell end and is used for fixing the fixing belt of housing and is arranged on keyhole above the fixing belt; be arranged on and be connected, be radial with inner walls in the housing, be used for the supporting frame of support housing.Described gas port comprises gas port 2A and gas port 2B.
Described housing: a, selection light weight, metal alloy compositions or carbon fiber composite that mechanical strength is high are made.
B, housing profile front end are that garden arc, middle part are that cone, end are Cylinders.
The integral thickness of c, housing is the same, and under the prerequisite that can bear air pressure and impact force, thickness of shell can approach.
Adopt after the said structure, reduced the resistance of housing, alleviated the weight of housing as much as possible, when stopping rammer effectively, can change the movement angle of rammer, thereby improve the ability of housing impact resistance air.
Described gas port comprises square hole or the hole, garden that is arranged on above the cone inclined-plane, housing front end and housing middle part, aperture: 1cm.Be arranged on the rectangular hole above the shell end Cylinder, the aperture: wide 2cm, long 30cm-50cm.When design, the gross area of gas port should be greater than the engine charge open area more than 1 times, and it is many that the gross area of gas port is tried one's best under the prerequisite that guarantees casing rigidity, to guarantee providing sufficient air to motor.The edge of gas port is the garden arc, the seismic wave and the resistance of air that produce during with the minimizing air flows.
Adopt after the said structure, gas port provides needed air to motor, has stopped passing through of the above rammer of diameter 1cm simultaneously, has reduced the seismic wave that produces because of air flows.
Described fixing belt is arranged on the housing least significant end, and it can be enclosed within motor head, and the band of certain width and thickness is arranged.Described keyhole is a plurality of holes, garden that are arranged on above the fixing belt.
Adopt after the said structure, make housing be securely fixed in the front end of motor.
Support frame as described above be arranged on be connected with inner walls in the housing, radial plate.
Adopt after the said structure, increased the intensity of housing.
In sum, housing has solved the technical problem that stops rammer, minimizing resistance of air and impact resistance ability of protective housing, gas port has solved protective housing provides technical problem from air to motor, fixing belt and keyhole have solved protective housing and motor is connected and fixed technical problem, supporting frame has solved the technical problem of casing rigidity, therefore the practical application of protective housing has just had the reliable technique assurance, and the flight safety for aircraft provides guarantee simultaneously.
