Patent number: 11661952Abstract: An aircraft includes an airframe, ducted fans, and ducts for carrying pressurized air for lift and thrust supplied by the fans. The ducts form part of the airframe and carry static and dynamic loads applied to the airframe. Ducting members supply lift and thrust and transmit them to other airframe components. The ducts also carry the ducted air to exits set distant from the fans to permit flight control of the aircraft. Ducting members also form airfoils creating lift for the aircraft.Type: GrantFiled: September 21, 2020Date of Patent: May 30, 2023Inventor: Thomas G. Stephens

Publication number: 20120049530Abstract: A wind driven generator includes a rotor disposed in a cylindrical duct and supported by a frame for rotation in response to wind flowing through the duct. The rotor includes plural circumferentially spaced paralleled rotor blades supported for rotation about a generally horizontal axis. Each blade is supported for pivotal movement to change blade pitch, angle of attack or camber as the rotor rotates. A pitch or camber control motor, self-governing wind vane mechanism, or governing mechanism is operable to move a circular cam to vary blade pitch or camber to control rotor speed. The duct is mounted on a mast having a base supported on a foundation for pivotal movement to face the wind for maximizing air flow through the duct. Electric power generators are connected to opposite ends of the rotor at respective power output or drive shafts.Type: ApplicationFiled: March 21, 2011Publication date: March 1, 2012Inventors: Thomas G. Stephens, Stephen C. Else
