Abstract

The invention relates to a Safir auxiliary power device starting test simulator and a control method. The Safir auxiliary power device starting test simulator comprises a rotation speed and rotation speed time curve control circuit, a gas temperature control circuit, a starting test simulator interface circuit, a signal generation unit and an impedance matching load unit; the signal generation unit completes input signal simulation; and the impedance matching load unit completes output signal simulation. By means of the Safir auxiliary power device starting test simulator and the control method in the invention, when the test run of the starting simulator is not carried out on the ground, the purpose of completely measuring technical parameters is achieved; simultaneously, a fault part inthe Safir auxiliary power device complete system also can be located accurately; therefore, the system security is effectively ensured; the test cost is reduced; the test period is shortened; and thepilot security is ensured.

Description

technical field [0001] The invention relates to a simulator, in particular to a Safir auxiliary power unit starting test simulator. Background technique [0002] During the ground commissioning process of the Safir auxiliary power unit equipped with Mi series helicopters, the Safir auxiliary power unit starting test simulator (hereinafter referred to as "starting simulator") is used to simulate and control the starting process of the auxiliary power unit and monitor the working status in real time ; It consists of six parts including a speed signal generator, a sequential logic control circuit, a temperature simulation circuit, a display monitoring circuit and a power inverter. The field can simulate and diagnose the faults of the auxiliary power unit and the starter box without a test run, and perform fault isolation. [0003] The objective shortcoming of the prior art: it can only carry out single-piece testing on some technical parameters of various products of the Safir...
