VTOL EFV-4B GC

TYPE:
Single Engine Powered-Lift Personal Air Vehicle
(PAV)

DESCRIPTION:
The Springtail EFV-4B is a fourth generation single engine powered-lift (VTOL) personal air vehicle (PAV), which uses the core technology developed on earlier models.

This model is the first "non-pure research" vehicle in this configuration.

EFV-4B has significant enhancements over the "A" model, including redesigned fans and variable pitch blades.

This aircraft will be employed for flight envelope expansion and capabilities testing.

Springtail EFV-4B a single operator vehicle that supports operator/pitch in a standing position.

There is a pair of ducts, slightly more than one meter in diameter, mounted on the upper end of the airframe above the operator.

Each duct contains a fan consisting of three blades which produce thrust in the vertical direction.

The fans are counter-rotating, eliminating the torque that is normally associated with a single rotor. The ducts and fans tilt, individually, about a common axis for pitch and yaw trim.

Vanes mounted in the ducts, just below the fans are used for directional control. The power plant for the aircraft is mounted on the airframe to the rear of the operator. The vehicle is operated by an advanced computer control system.
