VSP Hangar | eV-Twin Electric

File ID#	129
Manufacuter	Georgia Tech / Navy Research Lab
Model	eV-Twin
Units	Feet
Description	Design concept based on the Navy Research Lab 'Ion Dasch' concept by Rich Foch/Aurora as a electric fuel cell technology demonstrator. This variant removes the large hydrogen tank, and uses that volume for 2 additional passengers, as well as eliminating the strakes where the fuel cells were located. The key benefit of this concept is the elimination of scrubbing drag from the fuselage by moving the electric motors to the tails, as well as the two propellers now able to be larger, for increased mass flow. The propeller efficiency improvement is significant - however, a having a blown tail is non-optimal in other ways.
