LIFT Project

LIFT Lightweight Innovative Generator for Future Air Transportation

The aim of LIFT is to develop innovative, lightweight, multifunctional solutions for the inactive parts of a MW-class generator to be used within future hybrid-electric aircraft architectures. The generator system will be of a high power (>1MW), high speed (>10,000rpm) and will achieve low overall mass (i.e. >25 kW/kg) through the optimized use of high-strength, light materials, combined with the exploitation of the properties of such materials for improved thermal management.

As presented within this section, from the preliminary analysis on an existing 20kW/kg generator using conventional materials, it is foreseen that with the light-weighting innovations proposed herewith the overall power density of the generator could improve by around 50% to 30kW/kg, exceeding the set target of 25kW/kg. More importantly, through the demonstrated results and achievements within this project, the case for the next generation, cleaner hybrid-electric and electric aircraft will become increasingly stronger and accelerate the wider technology realization.
