Abstract:
Hybrid electric propulsion is a promising technology to achieve excellent overall vehicle performance. Electric propulsion enables new types and configurations of rotorcraft, but the poor energy density of batteries has limited the overall performance of electrically propelled aircraft. A hybrid architecture can take advantage of the high energy density of chemical/liquid fuels; but also utilize the advantages of electric propulsion technology. This advantage of a hybrid system can only be realized if the hybrid system can be implemented with sufficient energy conversion efficiency and low enough mass. If not done in a highly optimized way, the complexity of the hybrid system can lead to it being too heavy and too inefficient - the worst of both worlds instead of the best of both worlds. LaunchPoint EPS will present design details and test results of our flightweight 35 kW hybrid electric genset system. Overall estimated vehicle mass breakdowns and estimates of vehicle performance range-payload diagrams extrapolated from genset test data will be presented. Mass breakdowns for the hybrid propulsion system will be presented showing the complexity and potential for 'ass-creep' in the aircraft weight budget. Dynamic transient performance requirements and results for the hybrid propulsion system will be presented. Lessons learned on testing and commercializing a 35 kW flight weight genset will be presented.
