A Summary of Results from Phase 2 Dynamic Drop Testing of Energy Storage Systems for electric Vertical Take-off and Landing (eVTOL) VehiclesAdvanced Air Mobility (AAM) vehicles will soon be joining the fleets of current aircraft and rotorcraft as
new forms of transportation within airspaces around the world. These new types of vehicles have features
that are unlike current fleets, which often contain new materials and manufacturing methods and are
designed with non-traditional propulsion systems. These new aircraft are designed to be capable of
providing services for a variety of uncrewed missions including package delivery, medical transport,
disaster relief and firefighting, as well as passenger carrying missions such as air taxi. The business use
case for these types of aircraft requires frequent operation with high utilization rates, operations in the urban
environment, and for taxi carrying services, price-points comparable to traditional methods of
transportation currently available for use. The market is poised to begin test flights with a handful of
vehicles currently undergoing flight testing, making this changing landscape closer to reality.
