The questions of technical realization of the dynamic bench for the research of the activity of the engine-flywheel of the attitude control system and space vehicle stabilization

The main principles of the construction of a bench of measurement of the dynamic moments of the managing director-engine-flywheel are considered. The principle of activity of the control engine-flywheel is described. The analysis of existing benches of measurement of the moment of the engine-flywheel is carried out. The description of constructive, functional schemes of the developed measuring unit of a bench, its principle of action is resulted. The characteristic equations of elements of the measuring unit are received. The block diagramme of the measuring unit is determined and its key parametres are calculated. The description of the sensor of the moment, the sensor of a corner, an elastic-viscous support is resulted. The dynamic bench is as a result developed, allowing to make measurements of the dynamic moment simultaneously from four engines-flywheels in the Nanometer range, with accuracy not less than Nanometer. The dynamic bench is capable to measure the moment directly from the engine-flywheel that supplies more exact imitation of angular motion of space vehicle in a closed loop of tests of an attitude control system and space vehicle stabilisation.
