【Abstract】 The rotational speed characteristics of the inside turbine machinery is the key factor to relieving the safety device at a fixed distance for mechanical contact fuze. A test system for trajectory simulation, and measurement of the rotational speed characteristics of the turbine machinery is established in this paper. Using laser reflecting method, a non contact measurement system is achieved. By this way, the rotational speed to wind speed distributing regulation and the rotational speed to time distributing regulation are achieved. The test results are agree with the results of shooting practice, which provide scientific basis for the design of the mechnical contact fuze. This test system has significant value on the design of the mechnical contact fuze and on the supervision of the quality of all fuze products.更多还原
