tilt rotor/SLT hybrid

The tilt rotor/SLT concept is a hybrid of two hybrids. By combining the benefits of a separate lift/thrust system with those of a tilt rotor, this airframe carries significantly less dead weight during both horizontal and vertical flight operations.

  • Vertical lift propulsion may be downsized significantly, and highly optimized for static thrust.
  • Tilting nacelle propulsion may be downsized significantly, and highly optimized for dynamic thrust.
  • Nacelles are actuated through differential thrust, eliminating the need for actuators and other mechanics, turning dead weight into propulsion weight.
  • Each nacelle contains an IMU, and is independently stabilized while working in coordination with the main body.
  • Self tilting nacelles react quickly and allow excellent control during vertical and horizontal flight, providing vectored thrust and acting as control surfaces.
  • Complete stability during transition.

no actuators.

The tilt rotor/SLT uses nacelles that are actuated by differential thrust. IMUs and/or position sensors are located within the nacelles which are independently stabilized.

The use of multiple smaller rotors on the nacelles instead of a single, larger rotor provides faster reaction time which increases stability.

distributed vertical lift points

Unlike other tilt rotors, the TR/SLT concept has vertical lift distributed along the wingspan instead of lifting the aircraft by the wingtips. This eliminates the normal structural issues while allowing the wings to be of thin and lightweight construction.
