Definitions
- the present invention relates to a projectile for simulating a bird strike.
- Patent Document 1 discloses a related technique.
- the test with a simulated projectile is useful as a collision test for a member facing forward in an aircraft, such as a member that directly strikes a bird, such as a wing leading edge or an engine fan.
- a member facing forward in an aircraft such as a member that directly strikes a bird, such as a wing leading edge or an engine fan.
- a member behind these for example, an outlet guide vane or a low-pressure compressor located behind the engine fan
- the load profile immediately after the collision is far from the actual state, and it is severe. It became clear that the test would be too much.
- the present invention has been made in view of the above-described problems, and a projecting body capable of simulating an appropriate bird strike even for a member that does not directly collide with a bird such as an outlet guide vane or a low-pressure compressor.
- the purpose is to provide.
- a projectile for simulating a bird strike has a cylindrical outer contour having a front end and a rear end, an opening opened at the front end, and from the opening toward the rear end.
- a projectile capable of simulating an appropriate bird strike even for a member that does not directly collide with a bird such as an outlet guide vane or a low-pressure compressor is provided.
- FIG. 1 is a schematic load profile curve immediately after a collision.
- FIG. 2A is a plan sectional view of a projecting body according to a first comparative example.
- FIG. 2B is a plan sectional view of a projecting body according to a second comparative example.
- FIG. 3A is a plan sectional view of a projecting body according to an embodiment of the present invention.
- FIG. 3B is a plan sectional view of a projecting body according to a modification of the present embodiment.
- FIG. 3C is a plan sectional view of a projecting body according to another modification.
- FIG. 4A is a cross-sectional plan view of a projecting body according to another embodiment.
- FIG. 4B is a plan sectional view of a projecting body according to a modification of the present embodiment.
- FIG. 4C is a plan sectional view of a projecting body according to another modification.
- FIG. 5A is an elevation view schematically illustrating a mode immediately before the projection body is ejected.
- FIG. 5B is an elevation view schematically representing a mode in which the projectile is ejected.
- the horizontal axis represents the time T from the collision
- the vertical axis represents the load L. That is, the increase in load immediately after the collision is relatively gradual, and the load peak lasts for a relatively long time while repeating the fluctuation.
- Equation (2) the time for which the load is applied is estimated by Equation (2).
- L is the length of the projectile.
- the front end contacts the collision target, and the mass is applied to the collision target. Then, the subsequent portion is sequentially collapsed from the front end and applies the mass to the target.
- the projecting body is a cylinder or a shape similar to a cylinder
- the cross-sectional area A is constant from the front end to the rear end of the projecting body, and the velocity v is large immediately after the collision. It can be seen that a load is applied to the collision target. That is, it is clear that the load increase immediately after the collision becomes steeper.
- the conventional test using a projection body close to a cylinder or a cylinder is a test that is too harsh as a collision test for an outlet guide vane or a low-pressure compressor.
- the inventors examined the shape of the projectile that can simulate a collision with a member located behind the fan as follows.
- the projecting body 1 includes a cylindrical main body 3 and a tapered portion 5 that is a tapered cone toward the front end.
- the apex angle of the taper part 5 is 90 °, and the density ⁇ is equal to that of gelatin.
- the projecting body 1 ′ has a shorter main body 3 ′ and a longer taper portion 5 ′ than the projecting body 1, and the density ⁇ is the same as that of the projecting body 1.
- a load profile as shown by line a in FIG. 1 is obtained. The increase in load immediately after the collision is excessively mitigated and still not approximate to the line s.
- the outer contour of the projectile deviates from the cylindrical shape makes it difficult to support by the sabot during injection, as will be described later.
- the outer contour is preferably approximate to a cylinder, or any other shape considering the convenience of injection.
- the projecting body 10 includes a cylindrical outer contour having a front end and a rear end, an opening opened at the front end, and a rear end from the opening, as shown in FIG. 3A.
- a solid body 13 having a cavity 15 extending toward the surface.
- the solid body 13 is made of a gel or jelly substance such as gelatin.
- the outer contour can be a cylinder, for example.
- the cylindrical shape is advantageous for being supported by a sabot.
- any other shape taking into account the convenience of injection, such as a prism, may be used.
- the rear end of the solid body 13 may be a surface perpendicular to the axial direction, or may be a hemisphere or other shape suitable for injection.
- the cavity 15 has, for example, a tapered shape that tapers toward the rear end.
- the cross section of the solid body 13 is a circular shape in which the solid portion remains only in the vicinity of the circular outer contour from the front end to the rear end of the cavity 15. With such a shape, the overall volume can be maintained to a considerable extent while reducing the cross-sectional area at the foremost end.
- the tapered shape described above can be a cone.
- the tapered shape may be a pyramid.
- the taper shape can be determined according to the overall shape of the solid body 13.
- the entire solid body 13 is made of a gel or jelly substance.
- An example of such a material is gelatin.
- Gelatin has a density that approximates that of a bird's muscle, and its viscoelasticity also approximates, so it is suitable as a material for a projectile.
- the entire solid body 13 may have a uniform density, or may have a density gradient.
- the support 17 may close it. Further, as shown in FIG. 3C, the support 17 ′ may extend over substantially the entire cavity 15.
- a material having an appropriate rigidity and a lower density than the material of the solid body 13 is applied to the supports 17 and 17 ′.
- a resin such as urethane foam can be exemplified.
- the shape of the cavity 15 can be variously modified. For example, as shown in FIG. 4A, the cavity 15 'may extend over almost the entire length of the solid body 13, or conversely, may be limited to a limited range near the front end. If the cavity is long, the increase in load immediately after the collision is moderated. The length of the cavity can be determined according to the desired load profile.
- the diameter may be uniform or nearly uniform over the entire length.
- a hemispherical shape 15b or other shapes can be applied to the end of the cavity. With such a shape, the increase in load immediately after the collision is not uniform, and a multistage load profile can be obtained.
- a more complicated shape such as a cavity 15c shown in FIG. 4C can be adopted.
- the density is not limited to be uniform, and a density gradient may be given to the solid body 13. More load profiles can be designed by combining shape and density gradient.
- a load profile obtained by performing the same numerical calculation as described above based on the example of FIG. 3A is as shown by a line c in FIG.
- the degree of approximation to the line s is relatively good in the part where the load increases immediately after the collision and the plateau-like part where the load continues.
- These parts in the load profile curve are the most important parts for quality in simulating a collision. Since the degree of approximation is high in these portions, the projectile according to the present embodiment enables simulation of an appropriate bird strike for a member such as an outlet guide vane or a low-pressure compressor that does not directly collide with a bird. It can be said that.
- the projectile 10 according to the present embodiment is ejected by a gas gun 100 as shown in FIGS. 5A and 5B.
- the gas gun 100 is generally composed of a main body 102 that is a cylinder with an open front end, and a sabo 104 loaded therein.
- the sabot 104 has, for example, a cylindrical recess, and the projecting body 10 is loaded in the recess.
- a space inside the main body 102 and behind the sabot 104 is filled with compressed gas.
- the gas gun 100 also includes locking means for temporarily holding the sabot 104 in the initial position shown in FIG. 5A, and further includes stopping means for stopping the sabot 104 so as not to jump out from the front end.
- the entire gas gun 100 and the test body 110 loaded with the projecting body 10 are introduced into a vacuum chamber and placed under a vacuum of about several tens of Pa. Or the state nearer atmospheric pressure may be sufficient. Under reduced pressure, the air resistance is remarkably reduced, so that injection at a high speed close to subsonic speed is easy, and deformation of the projectile due to air resistance can be ignored.
- the locking means is released, and the sabot 104 is accelerated forward by the compressed gas pressure. Since the sabot 104 is stopped at the front end of the gas gun 100 by the stopping means, only the projectile 10 is ejected.
- the ejected projectile 10 collides with the test body 110 as shown in FIG. 5B.
- the projecting body 10 Since the projecting body 10 has a cylindrical outer contour suitable for being supported by the concave portion of the sabo 104, it is suitable for injection by a gas gun. In addition, the projecting body 10 has a cavity 15 inside, so that the cross-sectional profile is adjusted, so that an appropriate bird strike simulation can be performed on a member that does not directly collide with a bird such as an outlet guide vane or a low-pressure compressor. It is possible.
- a projectile capable of simulating an appropriate bird strike even for a member that does not directly collide with a bird such as an outlet guide vane or a low-pressure compressor is provided.
