Test Set A
The Test Set ‘A’ (Model No T0113) is a ground TESTER and designed specifically to check the parameters of “Engine Speed Control Amplifiers” used with Adour Mk. 804 and Mk 811 engines used in Jaguar Aircraft. The TEST SET A facilitates to test the amplifier parameters on both static engine and running engine conditions.
The test set A performs following functions under Static engine Test
Simulates temperature signal derived from engine TGT Thermocouples in the range of 250 to 750°C. - Simulates NL speed signals derived from L.P shaft probe in the range of 25 to 110% rpm.
- Indicates current drawn by solenoid of fuel control unit (FCU) from engine control amplifier.
- Indicates the voltage fed to the solenoid of fuel control unit (FCU) from engine control amplifier.
- Measures Simulated TGT and NL speed.
The test set A performs following functions under running engine Test
- Measures the temperature produced by engine TGT thermocouples in the range of 250 to 750°C.
- Measures NL speed signal produced by the L.P. shaft speed probes over the range of 3,400 to 15,000 r.p.m (25 to 110%).
- Measures the NH signal produced by the H.P. shaft tachometer generator over the range of 6,200 to 17,000 r.p.m (40 to 110%).
- Indicates the current, produced by the engine control amplifier, to the FCU solenoid on a LCD display in the range of 0 to 0.8A, within 3% accuracy.
- Indicates the voltage, produced by the engine control amplifier, to the FCU solenoid on a LCD display in the range of 0 to 30Volts D.C within 3% accuracy.
- Testing of Redatum TGT and Redatum NL.
