TVP Specifications

Open

  • Simple and light-weight single-axis vectoring through the center of thrust
  • Best for hybrid VTOLs, tilt-wings or as a retrofit for legacy vehicles
  • Pointing +/- 23˚ about the tilt axis
  • Mounting in any orientation
  • Pusher or Puller configurations
  • 3,600 RPM maximum rotational speed in either direction
  • 400 ft-lbs max torque (542 N-m)
  • Up to 40" propeller diameter (101 cm)
  • Fixed-pitch, 2-blade propeller
  • OEM propeller blade compatible

Ducted

  • Powerful single-axis vectoring through the center of thrust
  • Ideal for VTOL bicopters and multicopters
  • Pointing +/- 22˚ about the tilt axis

Nested

  • Powerful fully gimbaled vectoring through the center of thrust
  • Particularly well suited to tail-sitters and tailless aircraft
  • Pointing +/- 20˚ in any direction about the nominal thrust axis
  • Inherently quiet, improved propeller efficiency, safe around ground personnel
  • Mounting in any orientation
  • Pusher or Puller configurations
  • Accommodates off-axis engine mounting
  • 4,000 RPM maximum rotational speed in either direction
  • 510 ft-lbs max torque (691 N-m)

Notes:

Interrelated parameters may be reduced when approaching max values (ex; diameter, RPM, torque).

Flight Ready

Two flight articles are shown mounted on our VTOL test fixture. They include all the options listed above for Ducted single-axis vectoring. Each propulsor is mounted 5 degrees off its drive axis which is ground adjustable on this fixture.

At any power level the thrust vector of each propulsor can be pointed independently +/-12 degrees in less than 0.18 seconds.

The 44″ (112 cm) diameter propellers are spun at the same rotational speed, which may appear slower on video due to the wagon-wheel effect.  

The metrics measured  per propulsor are shown below.
