Description
Technical Field
The invention relates to the field of airplane tests, in particular to a bird bullet holder component and a bird bullet holder production method for a bird collision test.
Background
Bird strike is one of the main factors influencing the air flight safety of an aviation aircraft, and in order to ensure the flight safety of the aircraft, the aircraft must be subjected to a bird strike resistance verification test on structural components (including a nose and windshield structure, a wing leading edge and a tail wing leading edge).
At present, a bird collision test uses a poultry simulation flying bird, the bird needs to be wrapped and placed into a bullet holder, a bird bullet is shot out through an air cannon, the bird collision test is carried out, and the bullet holder can damage a test piece.
Disclosure of Invention
The invention aims to provide a bird bullet holder component and a production method of the bird bullet holder for a bird collision test.
The invention provides a bird bullet holder component, which comprises: mixing white materials and black materials according to a preset proportion;
wherein, the black material is MDI, and the white material is MSDS.
The ratio of white material to black material is related to the speed of the bird projectile.
The ratio of the white material to the black material is 1: X, and X is one number from 1 to 5.
When the ratio of white material to black material was 1:1, 150ml of white material and 150ml of black material were taken for 4 lbs of birds, and 200ml of white material and black material were taken for 8 lbs of birds.
The invention provides a method for producing a bird bullet holder for a bird collision test, which comprises the following steps:
coating a release agent on the interior of the mold;
mixing the two foaming materials, and quickly and uniformly stirring;
pouring the mixed foaming material into a mould, covering the mould and tightly pressing the mould;
taking out the prepared product after being prepared in a mold under a preset condition, and placing the product for 24 hours for use;
wherein, the mould is designed according to the weight of the bird specified by the inner diameter of the air cannon and relevant standard; the two foamed materials include: MDI and MSDS.
When the bird bullet support is not used for a long time, the bird bullet support is stored at the temperature of 18-25 ℃.
The preset conditions are as follows: keeping the temperature at 18-30 ℃ for 45 minutes.
Birds were divided into 4 pounds and 8 pounds.
The invention has the advantages that: the bullet holder produced by the method has light weight and high strength, and is not easy to break in a bore; the separation of the bullet holder and the bird bullet is easy to realize after the bird bullet is taken out of the chamber; the bullet support fragments are very light, and the test piece cannot be damaged even if the test piece is hit; the manufacturing process is simple and the cost is very low.
Detailed Description
The invention provides a method for producing a bird bullet holder for a bird collision test, which comprises the following steps:
(1) designing a mold: the size of the mould is designed according to the weight of the bird specified by the inner diameter of the air cannon and relevant standard standards, and two groups of moulds are required to be designed for two types of birds, namely 4-pound birds and 8-pound birds.
(2) Foaming material: polymethylene phenyl isocyanate MDI (black material) and combined polyether MSDS (white material), 150ml and 150ml are respectively taken from 4 pounds of birds; 200ml and 200ml of 8 pound birds were taken, respectively.
(3) Making a bullet holder: firstly, coating a release agent on the interior of a mould, then mixing the two foaming materials, quickly and uniformly stirring, pouring the mixture into the mould, covering the mould, pressing the mould tightly, keeping the mould at the temperature of between 18 and 30 ℃ for 45 minutes, taking the mould out, and standing the mould for 24 hours for use. The elastic support is stored at the temperature of 18-25 ℃ when not used for a long time.
