In the such scheme, the most advanced and sophisticated line face that plane, water inlet place and described cutwater are split is in the same plane or place the place ahead of most advanced and sophisticated line face.
In the such scheme, described water brake device is with respect to described cutwater splitter end line symmetry.
In the such scheme, the rocket of described conduit pipe outside sled car body front end is provided with fiaring cone.
Beneficial effect of the present invention is:
1. because the water brake device is arranged on the front portion of rocket sled car body, and can place in the rocket sled car body and car body fusion design, when the water brake device bumps against tank, can be so that water brake device and car body bear the substantial load of current all directions jointly, this structure makes the brake load of rocket sledge braking section have short, the most direct power transmission route, and the additional bending moment of its generation is minimized, brake speed can reach 1.85 Mach.
2. the water brake device is arranged on rocket sled Vehicular body front, can not cause a devastating effect to body construction even the water brake device destroys to some extent, and this water brake device is relatively independent, and has good portability.
3, the rocket of described conduit pipe outside sled car body front end is provided with fiaring cone, and fiaring cone can reduce aerodynamic drag to carrying out rectification, and effect is more obvious in the supersonic speed test.
