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.
Our thrust-vectoring technology removes the need for tilting of the fuselage or the rotor system in any of our VTOL aircraft.
This improvement to the current technology eliminates the complex transition process from vertical to forward flight while reducing the number of lifting motors and bulky components inside the wing. Less weight and drag translate to more efficiency and higher speed capability compared to an SLT or tiltrotor aircraft.
An example of this can be seen in our quadcopter designs. They fly level in forward flight allowing us to replace the round rods with wings. The lower profile wings combined with the non-tilted fuselage reduce drag while generating lift. The result is a big increase in aerodynamic efficiency. The horizontal orientation of the rotors eliminate a phenomenon called p-factor increasing lift and thrust efficiencies . For these reasons as well as others, our technology will make a quadcopter significantly faster and more efficient.
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 will address 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
