2.3 I.C.S.
The
I.C.S.
(intelligent Control System) is a total system for the control of a model gas turbine
engine. Its main function is to control and regulate the fuel pump, providing the turbine engine
with the necessary amount of fuel for safe and controlled operation.
The
I.C.S.
measures the exhaust gas temperature, the relative position of the throttle stick
and the rotor speed. It monitors all of the controls necessary to guarantee that the engine
stays between the user-defined parameters of operation, also providing fail-safe shutdown of
the engine when it has detected any important anomaly. In order to make this assessment,
the
I.C.S.
has a RPM sensor, a thermocouple input, a throttle servo input, power connections
for the fuel pump, starter, glow plug, fuel and gas valves, battery and a digital (RS232) serial
port to program and read the data in real-time to a PC.
The measurements made by the I.C.S. are:
Temperature of the exhaust gas
Pump battery voltage
Width of the throttle pulses from the radio
transmitter
Engine rotor RPM
Engine run time
External analog signal
All of these measurements can be read into and displayed on the Hand Data terminal (HDT)
that is connected to the
I.C.S.
by a RJ-45 connector, or into a personal computer through a
RS232 adapter. The configuration/setup parameters are stored in the
I.C.S.
by the HDT or
the PC.

RPM input: Magnetic sensor up to 250,000 R.P.M.
