Conceptual and detail design of HW (TN01000029/4-V1) - 100% UNIS
Original language description
The EHXX unit is designed to control the H-series aircraft engine of GE Aviation, Czech. The unit is designed as a single-channel programmable with independent over-speed protection. Control and monitoring functions are implemented by the HERCULES processor. The unit communicates with the superior system via the CAN communication interface, the CANAerospace protocol. The power supply of the unit is provided from the on-board network of the aircraft, with DC voltage from 18VDC to 32VDC. The primary task of the unit is to ensure the starting and safe operation of the aircraft engine (activation of the ignition system and setting the required fuel flow to the engine) and its shutdown, respectively. switching to backup control in case of fault detection (switching off fuel and switching to hydro mechanical backup). The unit is controlled by an input for connecting SPCL levers (Single Power Control Lever) and a set of digital inputs for setting the operating mode and activating control functions. The operating parameters of the motors are monitored by means of temperature and speed sensors, torque sensors and limit switches for the positions of electromechanical actuators. The error status is signaled by a two-state output and at the same time detailed information is sent via the CAN bus. In addition to the above functions, the unit also controls the rotation of the propeller in ALPHA and BETA mode based on predefined maps and dependencies.
