AH-64D - Development Report

Powerplant

The detailed model of the T700-GE-701C powerplant, its Hydromechanical Unit (HMU), and Digital Electronic Control Unit (DECU) have been developed. This includes the compressor and its hydromechanical unit, compressor turbine, combustion chamber, and power-turbine. 

Calculations of the angle of attack on both the compressor and turbine blades allow us to determine dependencies between the power-turbine state (main rotor RPM rise or fall for instance) and the state of the compressor, which in turn affects the behaviour of the power-turbine. This allows our model to closely match realistic behaviour in the transition processes for speed changes, main rotor pitch changes, and anti-torque pedal routines.

The engine, DECU and main rotor characteristics modeling have achieved an accuracy error of 2-3% for documented normal flight parameters and 4-5% for emergency flight regimes and environments (high temp. from 35°? and above as well as high altitude low density regimes).

Engine, Flight and Fuel Pages

The Engine page provides important data on the aircraft's engine torque, temperatures, RPM, and main rotor speed. The Flight page includes heads-down information on the performance of the aircraft with the ability to set important mission flight data. The fuel page includes an intuitive display of the fuel storage, flow and transfer systems.
