A new propulsion system that provides added thrust for takeoff and during go-arounds promises to improve short-field takeoff and landing (STOL) capabilities for a variety of small aircraft types. Depod (distributed electric propulsion on demand) integrates an electric motor into the wings of the aircraft to enhance thrust during critical operations. Visitors to EAA AirVenture can see the Depod system at the Aeromarine exhibit in the show's main display area.
By mounting the propellers and motors into the wing of the aircraft itself, takeoff thrust is greatly improved, allowing for shorter takeoffs in a variety of aircraft. The thrust provided during takeoff can also be reversed to assist the pilot during landing on short runways. While not in use, the propellers fit into the inside of the wing to reduce drag and the Depods will only be activated again at the pilot's command. Each Depod unit has its own lightweight battery pack, and as it isn't designed to run full-time, can provide full power for 10-15 seconds during takeoff, 15 percent power for 30 seconds on approach to landing, and 5 seconds during landing.
Additionally, the system can improve roll control by adding airflow to an aircraft’s control surfaces, and in the event of an engine failure, Depods could provide additional power to help a pilot to complete a turnback to the runway safely or find a more suitable place to land off-airport. Depods can also be programmed to help counter inadvertent yaw, according to the developer, Aeromarine, and "help prevent spins such as the deadly base-to-final stall/spin event." Seaplane pilots could also use Depods for maneuvering and docking on the water.
