INTRODUCING DYNAMIC-VARIABLE PITCH. 

NEVER BEFORE SEEN CAM AND AIRCRAFT TECHNOLOGY. 


Dynamic-Variable-Pitch

Bird wing dynamics

Background

Our revolutionary cam technology is inspired by the characteristics of bird and insect flight. Until now airplanes and helicopters had to rely on standard variable pitch and cyclic pitch in order to manipulate propellers and rotors. DYNAMIC  VARIABLE PITCH  is an all new approach that enables a more free-form control. Thrust vectoring and the countering of dissymmetry of lift are two separate and unique features of this technology. Because of this, many new types of aircraft with speed and efficiency benefits over the state of the art are now possible.




THRUST VECTORING

Our thrust-vectoring technology removes the need for tilting of the fuselage or the rotor system in any of our VTOL aircraft. Instead of changing the angle-of-attack of a helicopter or eVTOL rotor to create forward thrust, we change the pitch of the rotor blades through one half of the rotor arc. 

This improvement to the current technology eliminates the complex transition process from vertical to forward flight while keeping the profile of the aircraft streamlined and efficient.

In hover, our space-conscious lift-rotor configuration gives us an efficiency and power density advantage of 2-3 times over the state of the art.

COUNTERING DISSYMMETRY-OF-LIFT

Countering dissymmetry of lift (DOL) in helicopters is another unique feature of our cam. DOL and retreating blade stall are major limiting factors in the top speed of a helicopter. Our unique cam design manages this aerodynamic limitation more effectively than a helicopter swashplate by holding a higher average pitch angle in the retreating blades and a lower average pitch angle in the  advancing blades. Data from our proof of concept prototype showed a significant improvement of 75%, with a 125% improvement projected in future testing
