Abstract

The invention provides a water brake system for a rocket sled, which comprises a water brake arranged on a rocket sled vehicle body and a water tank arranged on a track braking section of a rocket sled track, wherein the water brake is arranged on the front part of the rocket sled vehicle body and comprises a water inlet, a water splitting wedge and two water guide channels which are arranged symmetrically on the left and right; the water inlet is arranged in the center of the front end of the rocket sled vehicle body, and the water splitting wedge separates the water inlets into left and right parts to be communicated with the two water guide channels respectively; the water outlets of the two water guide channels are arranged on the two sides of the rocket sled vehicle body respectively; and the water tank is a strip water tank made of a light and brittle material and contains water, the water tank is arranged on a water tank track which is positioned between the two rails of the rocket sled track and parallel to the rocket sled track, and the position of the cross section of the water tank relative to the rocket sled track is consistent with the position of the water inlet relative to the rocket sled track. The structure makes the brake load of the reducing section of the rocket sled have the shortest and most direct power transmission line and minimizes added bending moment generated by the brake load.

Description

technical field [0001] The invention belongs to the technical field of rocket sled slide rail testing, and in particular relates to a water braking system of a rocket sled. Background technique [0002] Traditional double-track rocket sleds usually use bucket-type water brakes installed at the lower part of the main structure of the sled body. This kind of brake not only has a heavy mass and large additional resistance characteristics, but also produces a large pitching moment when braking. Therefore, it is necessary to increase Rigidity and strength of the car body structure and increased engine thrust. Due to the structural limitations of this rocket sled and the existing power matching conditions, it is difficult for the traditional double-track rocket sled to brake at a speed exceeding Mach 1. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a water brake system that can be used at supersonic speeds and can w...
