Abstract

1,101,219. Measuring altitude rate electrically. COLLINS RADIO CO. Aug. 4, 1966, No.35014/66. Heading G1N. In an aircraft control system a rate of change of altitude signal is produced at 11, Fig. 1, and supplied via a low-pass filter 14 to a mixer 16, and a vertical acceleration signal is produced at 18 and supplied via a band pass filter 25 to the mixer 16, the output of which represents the altitude rate. The uncorrected altitude rate signal from 11 is passed through a circuit 13 which removes unwanted quadrature components; and in the filter 14 are removed high frequency components arising from electrical and aerodynamic noise. The filter 14, however, removes true high frequency components of the signal and introduces some lag, and to counteract this the high frequency components are effectively reintroduced from the band pass filter 25. The band pass filter 25 removes from the acceleration signal from the accelerometer 18, low frequency components due to the earth's gravitational force, and other components due to various steady state errors in the accelerometer output. The output of the accelerometer 18 has added to it at 20 a signal from gyro-vertical transducer 21 supplied via a shaping circuit 22, to correct for errors arising from banking.
