How it works
Engines channel thrust through tubes, which is then expelled from nozzles to generate the torque required to power the rotor blades. This system removes the need for transmissions, gearboxes, driveshafts, long tail booms, and counter-torque devices.
Our patented system (US 11,753,155B2 and European EP3774532) leverages micro-turbojet engine thrust generated near the helicopter rotor shaft, delivered by specialized ducting to expelling nozzles positioned sufficiently far from the rotor shaft to provide the necessary torque for helicopter propulsion. This innovative power train is isolated from the fuselage by bearings, thereby eliminating the need for anti-torque mechanisms such as tail rotors and related hardware. This revolutionary design removes gearboxes, tail rotors, tail booms, and drive shafts, along with the associated weight, manufacturing, and maintenance costs of these accident-prone mechanisms.
Supplies fuel and electrical connections to engines through the rotor shaft.
Yaw Control
Our innovative solid-state yaw control motor operates on the rotor shaft to manage yaw, eliminating the need for air-driven tail assembly yaw control devices used in previous reaction drive helicopters.
