Introducing the HopFlyt
HopFlyt Venturi is the only aircraft combining variable incidence wings & canards with channels, distributed electrical propulsion (DEP) and contra-rotating propellers in an electrical Vertical Takeoff & Landing (eVTOL) design. The use of these advanced technologies in our patent pending design will deliver superior speed & ride quality for passengers at lower battery consumption rates while reducing exhaust pollution.
Advanced Aerodynamic Design
Utilizing a canard style design, the Venturi results in higher safety & a smoother ride experience for the passengers and the pilot alike. The wings tilt up for takeoff & landing, tilt down for forward flight and vary their angle while flying; hence “variable incidence.”
By using variable incidence wings & canards with channels, Venturi achieves wing-borne lift while hovering, which significantly reduces its battery power consumption. Combining these technologies with DEP reduces mechanical complexity by removing traditional flight control surfaces (i.e. ailerons, elevators, rudder and flaps). This reduces weight, improves reliability and reduces maintenance while allowing the aircraft to takeoff and land vertically.
Wings and canards can vary angle in-flight and improve ride quality by keeping the fuselage at a level attitude during all phases of flight.
The powered channel wing design creates high levels of lift by efficiently accelerating air over the wing resulting in longer battery life. While the contra-rotating propellers produce more thrust and reduce noise.
Control of the Venturi is provided by Distributed Electrical Propulsion (DEP) and the independently variable incidence wings and canards.
Key Aerodynamic Principle
Air is drawn into the channels by the contra-rotating propellers. The channels have an aerofoil shape, which generates high levels of wing-borne lift as the air is accelerated through the channel, even when the aircraft has zero forward airspeed. These high levels of lift have been demonstrated through flight test & NASA wind tunnel data on other aircraft.
Additionally, the design reduces complexity, total parts count and aircraft weight, which further boosts the design efficiency.
Subscale Prototyping
HopFlyt has completed a prototype build of the Venturi and started early stage flight test in order to demonstrate the variable-incidence and channel wing technology. The aircraft fuselage and wing components are 3D printed from engineering drawings and skinned with carbon fiber.
