Abstract
The method according to the invention makes it possible rapidly to accelerate a test piece in a start-up phase in accordance with a stipulated acceleration program, and subsequently to maintain the test piece at constant acceleration during an arbitrary time. The testing device for carrying out the method consists of a rotor carrying the test piece. The rotor is accelerated by a pressure medium in its start-up phase and is driven in its stationary phase by an electromotor via a toothed belt. In the start-up phase, the test piece experiences a continuous rotation from the tangential direction of the circular path (K) into the radial direction by the angle of rotation .psi. of 90.degree.. A preferred use of the device resides in testing rocket nose cones. This replaces real launching and/or expensive linear accelerators.
