Annotations languages:

In the article the use is considered signal-parametric approach to diagnosing of the functional state of electromechanics block of space vehicle. In theory and it is experimentally shown that without a change the construction of object of diagnosing, on the supervision of output signal of sensor of angular speed of rotation of engine of fly-wheel on transient behaviors it is possible to distinguish refusals, caused the change of coefficients of passing to of sensor speed, electronic chart of engine management, and also by the change of moment of resistance the rotation of engine-fly-wheel. The use of programmatic imitators of refusals is offered for debugging and adjusting the diagnostic providing.
