Personal Jet VTOL under development

Pressbox (Press Release) -
VertiFan, Inc. is developing a vertical takeoff and land (VTOL) aircraft that will not only fly in the hover mode with all the agility of a helicopter, it will also trasition to aerodynamic flight and cruise at 340 knots.
The 4-place aircraft will utilize two of the new FJX-2 Williams turbofan engines being developed by Williams under the General Aviation Propulsion program. The engines will cost about the same as a piston engine and be very fuel efficient.
The engine thrust is diverted to turbine buckets on the rims of the lift fans, spinning them up to produce lift for vertical flight. This pneumatic coupling eliminates all trasmissions, drive shafts, variable pitch blades and other high maintenance mechanical parts, resulting in a safe and reliable aircraft. The lift fans produce three times the thrust of the installed engines.
To transition to forward flight, louvers under the fans vector the aircraft forward until 80 knots of speed is reached. At that point the jet thrust is directed out the tail pipe, the louvers are closed under and over the fans, and the aircraft becomes a high speed jet aircraft.
