Shows the simplicity of Thrust Drive's direct drive system vs Conventional complex and failure prone drive train.

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.

  • Eliminates transmission, tail rotor, gearboxes, drive shafts, and tail rotor structure, along with their associated weight, costs, and critical points of failure.

  • Improved power-to-weight ratio; increases payload capacity and available space.

  • Offers engine redundancy for enhanced safety.

  • Eliminates tail rotor dangers such as boom strikes and tail strikes.

  • Substantial reduction in operating, maintenance, and manufacturing costs.

  • Compatible with existing regulations, pilot skills, and takeoff/landing facilities.

  • Improved autorotation capability due to reduced friction from the elimination of the mechanical drivetrain.

  • Additional time to reduce collective pitch during autorotation due to the enhanced rotor inertia.

  • Significantly quieter and more efficient than previous reaction drive helicopters.

  • Decreases cabin noise, vibration, and heat from the engine.

  • Utilizes components based on existing and proven technologies.

  • Provides the potential for significant speed increases.

  • Scalable design, adaptable for small drones to heavy-lift helicopters.

  • Likely to result in lower insurance costs over time.

  • U.S. and European patents issued; additional patents pending.
