Aerospace Instrument-Making Annotation << Back Hydrodynamic forces influencing the float of floating pendulum accelerometer at asymmetric leakage of liquid into butt ends С.А. Анциферов, Л.И. Могилевич The asymmetry of liquid leakage out of cylindrical slit of a working chamber into butt ends slits of floating pendulum accelerometer is investigated. It is shown that if we take into consideration simultaneous progressive and angular vibration of foundation to which accelerometer is fixed, therefore the force at angular vibration is added to the force from the liquid influencing the float at progressive vibration. In case of symmetric leakage or its absence [1 - 5] the force at angular vibration of the foundation equals zero. The law of float movement in a working chamber and foundation angular vibration influence on this movement is defined.
