    Growth in air traffic poses the question of how to achieve a more sustainable way of flying with a reduced amount of environmental damages and especially costs. One of the options to attain the lower cost flight is to utilize more electric power. Implementing the more electric technology in new aircraft "More Electric Aircraft (MEA)" achieves several advantage such as reducing the operation and maintenance cost and optimizing the performance:

    • Specific consumption gain
    • Total weight and volume gain
    • Increase of flight safety
    • Noise reduction
    • Enhanced performances on flight domain
    • Potential for Low Recurring Cost
    • High power-to-weight/power-to-volume system ratio

    Future aircraft will tend to use electrical power rather than hydraulic, pneumatic or mechanical power. At the core of this E-Drive are the gearbox, electric motor and power electronics inverter, with key functional issues being: high frequency operation, reliability, fault tolerance, power waveform quality, elevated temperature operation, and EMI regulation compliance.

    These innovative E-drives will enable new system technologies for more environmentally friendly aircraft, e.g.:

  • What the AEGROUP offers:
    Within future Aircrafts the associated electrical rotating machine weight increase can be a drawback for many MEA architectures. Consequently the AEGROUP aids aerospace customers to identify solutions to reduce the mass (torque/power density) of these machines by implementing:
    • Optimization/analysis of the current E-drive,
    • New integrated E-drive ideas,
    • Increase rotational SPEED, e.g. > 314 m/s
    • PM-less electrical machines,
    • Fault tolerant machines,
