Abstract

Development of aviation and weapons envisages the speed characteristics enhancement of newly developed aircraft. The requirements for test bench equipment, including braking devices employed on the rocket-rail track, are being increased. Braking expands the high-speed track tests functionality, increases their efficiency and informativity, reduces the preparation time and cost due to the reuse of the retained material part. Solution to the problem of braking rocket sleds moving along a rocket track at a speed of more than 1.200 m/s envisages the development of braking devices ensuring effective and safe braking in the entire speed range. Selection of the braking type for the promising braking device on the assumption of its technical capabilities is being required.

The article describes various types of braking employed on the rocket track facilities when testing objects of aviation and rocket technology. Technical capabilities of the conventional types and means of braking are determined including their advantages and disadvantages, as well as their application scope. Analytical study on the types of braking acceptable during high-speed track tests is adduced.

In the course of the conducted research, it was determined that braking of high-speed rocket sleds is advisable to be performed not by a single type of braking, but by several ones, applying a set of braking devices. A single type of braking is effective and safe only in a limited speed range.

Achieving hypersonic speeds on the rocket-rail track requires modernization of the technological equipment, including braking devices, as well as developing new techniques for the tests conduction.

Solutions should be elaborated to ensure braking of the objects moving under conditions of a rocket-track facility at new high-speed boundaries, as well as methods of mathematical computation of operation of the braking devices being employed should be determined.
