Abstract :
The hydraulic system of an aircraft or hydraulic power system is a system
on aircraft that uses the pressure of liquid (hydraulic) as a medium. Hydraulic
systems are used to drive the system associated with other components, such as
driving ground spoilers, flight spoilers, leanding gear, nose gear steering, trailing
edge flaps, leading edge devices, ailerons, elevators, leanding gear brakes,
rudder and thrust reversers.
The study was conducted to find out the hydraulic power produced and the
hydraulic minimum pressure needed for the flight control on TM13 aircraft. This
research was conducted using the literature study method by collecting data from
the A340 aircraft to be applied in the TM13 aircraft. Load calculation was done
on ailerons, elevators, and rudder.
The results showed that the load produced in the aileron was 36.93 KW,
elevator was 373.8 KW, and rudder was 77.27 KW. The minimum hydraulic
pressure required by the aileron actuator was 1960 psi, elevator actuator was
1964 psi, and rudder actuator was 1785 psi.
