Lift Reinvented: Propeller Slipstream Repurposed

PropWings harnesses propeller slipstream energy to generate increased lift. By utilizing this available energy source, PropWings technology enables eVTOL aircraft to more rapidly transition to horizontal flight and generate lift from their main wings, fixed or tiltable, once the rotors have initiated vertical take-off.

The very large power demand required for vertical take-off and transition to forward flight is a major challenge for eVTOL viability. PropWings’ propulsive lift technology doesn't eliminate the power demand, but provides a significant energy offset by accelerating the transition to more efficient main wing lift.

Since main wing forward flight is more energy-efficient than helicopter-rotor forward flight, shortening the transition phase conserves battery energy. And PropWings generates lift during cruise, providing a continuous efficiency boost. As a result, battery energy is saved in both transition and cruise phases, extending flying range.
