Thrust Drive System
Here is something more contemporary:
Thrust Drive System Announcing Game Changing Helicopter Drive System
Picture
The system uses a unique and powerful propulsion technique to deliver thrust through specialized aerodynamic tubes and nozzles to provide the propulsion to power the rotor blades.
Benefits of this new technology include:
- ELIMINATES TRANSMISSION, TAIL ROTOR, GEAR BOXES, DRIVE SHAFTS & TAIL ROTOR STRUCTURE ALONG WITH RELATED WEIGHT, COST, AND CRITICAL POINTS OF FAILURE
- VASTLY QUIETER AND MORE EFFICIENT THAN PRIOR REACTION DRIVE HELICOPTERS
- ADDITIONAL TIME TO LOWER COLLECTIVE PITCH DURING AUTOROTATION DUE TO THE HIGH INERTIA OF THRUST DRIVE SYSTEM
- GREATLY ENHANCED AUTOROTATION CAPABILITY DUE TO SEPARATE DECOUPLING OF ROTORS
- ELIMINATION OF TAIL ROTOR DANGER, BOOM STRIKE/TAIL STRIKE
- REDUCTION OR ELIMINATION OF VORTEX RING STATE
- COROTATING AIRFOILS QUIETER THAN CONVENTIONAL HELICOPTER
- ABSOLUTE VERTICAL TAKEOFF AND LANDING
- DECREASED ENGINE CABIN NOISE, VIBRATION & HEAT
