The traditional helicopter drivetrain involves an array of components including transmissions, gearboxes, drive shafts, long tail booms, and counter-torque mechanisms. This complexity introduces multiple potential points of failure within the system.
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.

PROPULSION SYSTEM
PROPULSIVE EFFICIENCY
Jet thrust is directly converted into rotor shaft power
Reduces weight, power loss, complexity and points of failure created by the conventional helicopter transmission and tail rotor.
This small and lightweight turbojet engine delivers a high volume of thrust at low pressure through the velocity stack positioned at the inlet of the thrust tube. The thrust tube channels airflow several feet outward from the rotor shaft before it passes through a 90-degree elbow. The thrust then exits the elbow, generating the torque required to drive the rotor shaft.
Thrust Drive LLC thrustdrive.com Introduction The Thrust Drive System represents a significant advancement in helicopter propulsion technology, offering notable improvements in safety, performance, and operational efficiency. By reimagining traditional helicopter mechanics, this system addresses longstanding challenges associated with conventional drive systems.
This illustrates the outlet where jet thrust exits the airfoil-shaped fairing, generating rotational torque to drive the rotor shaft.
