JETcopter Reveals New VTOL Design
Copterplane Could Fly In 18 Months

Start-up VTOL manufacturer JETcopter is proposing to build a new-design aircraft that uses a pair of top-mounted, piston-engine powered, enclosed centrifugal air, contra-rotating, high-speed turbines that then divert thrust to four vectored nozzles for directional control. The nozzles are mounted to the ends of two sets of wings that pivot to provide lift during horizontal flight.
