Springtail Vehicle Specifications


Trek Aerospace's Springtail Exoskeleton Flying Vehicle is a single operator powered-lift vehicle that supports the operator/pilot in a standing position. There are a pair of ducts, approximately one meter in diameter, mounted on the upper end of the airframe above the operator. Each duct contains a fan consisting of five 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 fly-by-wire computer control system.

Springtail Exoskeleton Flying Vehicle (EFV-4A)

The Springtail EFV-4A is a fourth generation single engine powered-lift research vehicle. This craft was built for the express purpose of testing and proving our core technology. This was accomplished on November 5, 2003 when transition to forward flight was achieved. This vehicle is still in service and is being employed as a test bed for further enhancements and refinements to the technology. We are currently using this vehicle for expansion of the flight envelope.

Springtail Exoskeleton Flying Vehicle (EFV-4B)

Using the core technology developed on earlier models, the Springtail EFV-4B 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 was employed for flight envelope expansion and capabilities testing in 2005.
