Blainjett Says Its Variable Pitch System Gives eVTOL Developers New Propulsion Options
The Delaware-based start-up's Dynamic Variable Pitch technology is being evaluated for Horizon Aeronautics' Hoverbike and for a drone being developed by Praxis Aerospace Concepts.
Blainjett Aviation is offering eVTOL aircraft developers what it says will be a more efficient lift rotor propulsion system than currently available tilt-rotor and ducted fan designs. Its patented Dynamic Variable Pitch (DVP) technology was recently adopted by Horizon Aeronautics for its in-development Hoverbike, but the Delaware-based start-up says it could be used for larger vehicles.
According to company founder Cary Zachary, the DVP concept avoids the need to change the angle of attack of an aircraft’s rotors to support the forward thrust required for cruise flight. Instead, the system changes the pitch of the 32-inch-diameter blades using Blainjett’s proprietary cam and flexible plate mechanism.
