METHOD AND DEVICE FOR STABILIZATION OF PRESET FLIGHT ALTITUDE OF FLYING VEHICLE Russian patent published in 1995 - IPC

FIELD: aeronautical engineering. SUBSTANCE: signal U_c(Δt) proportional to ambient temperature change Δt is shaped in temperature compensation unit. This signal is furnished through amplifier to actuating motor together with output signal of inductance pickup which is proportional to change in flight altitude of flying vehicle. Actuating motor rotates disk of pulse modulator through reduction gear whose output pulses are furnished to complementing input of pulse counter showing present flight altitude. As soon as the preset flight altitude has been attained, comparator sends signal for operation of switch which feeds power to electromagnetic clutch. As a result, voltage at potentiometer output is proportional to deviation from preset flight altitude. EFFECT: high accuracy of determination of preset altitude due to taking into account the ambient temperature. 3 cl, 2 dwg
