摘要： The turbine expansion ratio is calculated by a dividermultiplier circuit which divides a direct current compressor discharge pressure signal of a magnitude proportional to the compressor discharge pressure by a direct current turbine exit pressure signal of a magnitude proportional to the turbine exit pressure to produce a direct current turbine expansion ratio signal of a magnitude proportional to the turbine expansion ratio. A curve generator responsive to the turbine expansion ratio signal produces the reciprocal of a K factor signal which is a function of the turbine expansion ratio signal. A direct current mass fuel flow signal of a magnitude proportional to the mass fuel flow is divided by the compressor discharge pressure signal and the quotient multiplied by the reciprocal of the K factor signal in a second divider-multiplier circuit and a direct current burner inlet temperature signal of a magnitude proportional to the burner inlet temperature is added to this product to provide a direct current signal of a magnitude proportional to the computed turbine inlet temperature.

摘要： A divider-multiplier circuit for dividing a first direct current potential signal by a second direct current potential signal and multiplying the quotient by a third direct current potential signal. During respective alternate half cycles of a series of square waveform alternating current reference signals, a dividend signal is applied through a potential sensitive switch to one input circuit of an integrating operational amplifier, which integrates this signal in a first direction, and a divisor signal is applied through another potential sensitive switch to the input circuit of the integrating operational amplifier which results in an integration thereby of the divisor signal in a second opposite direction. While the second direct current potential signal is being integrated, the third direct current potential signal is applied through a third potential sensitive switch to a direct current potential signal averaging circuit until the second direct current potential signal has been integrated to substantially zero, at which time a switching arrangement sensitive to a substantially zero output signal from the integrating operational amplifier extinguishes the third potential sensitive switch.
