Technology Maturation, Risk Reduction, Test, and Evaluation of Hybrid Electric Aircraft Propulsion Systems

Electra Aero Inc. (“Electra”) is developing hybrid electric powertrain, power, and propulsion systems for hybrid electric aircraft. Electra is currently flight testing a hybrid electric propulsion system on its 2-passenger prototype aircraft and intends to conduct additional test and analysis to incorporate on its 9-passenger production aircraft in development. In this document Electra proposes a statement of work intended to address all six sub-fields of the Army’s Hybrid Electric Powertrain, Power and Propulsion Systems (HEPPS) Open Topic Direct to Phase II solicitation which will contribute to the development of operational aircraft. Key capabilities of these hybrid electric aircraft include the ability to take off and land within 300 ft via distributed electric propulsion, self-deployment from Forward Arming and Refueling Points (FARPs), and mobile power generation, which may be of interest to the U.S. Army. Additionally, Electra’s propulsion development activities are widely applicable to other vehicle configurations, including Group 4/5 uncrewed systems, rotorcraft, and tiltrotors.
