The focus areas includes this topic:
14. Focus Area: eVTOL/UAM (Electric Vertical Takeoff and Landing/Urban Air Mobility)
The objective of this topic is to explore potential commercial products being developed in the emerging eVTOL/UAM market for potential disaster response, humanitarian aid, and logistics missions. This sub-topic is intended survey a large scope of technologies to include: autonomy; advanced aircraft materials and manufacturing; novel acoustics techniques; subsystem, aircraft, and portfolio design tools; rapid mission planning for dense air environments and logistics efficiencies; command and control of air vehicles; robotic landing gear; large flotation devices; modular payload designs; air vehicle data networks and RF waveforms; sense and avoid architectures, algorithms, and sensors; electrical power storage, generation, charging; distributed electric propulsion control techniques.
