Airfoil Suitable For Forward And Reverse Flow
US Patent:
2002000, Jan 17, 2002
Filed:
Jun 8, 2001
Appl. No.:
09/877268
Inventors:
Jay Carter - Burkburnett TX, US
John Roncz - Elkhart IN, US
John Roncz - Elkhart IN, US
International Classification:
B64C003/00
US Classification:
244/03500R
Abstract:
An airfoil has a concave rear top surface, a concave rear bottom surface, and a rounded trailing edge to increase the lift-to-drag ratio of the airfoil at small angles of attack when air is flowing from the trailing edge to the leading edge (reverse flow), while maintaining a high lift-to-drag ratio when air is flowing from the leading edge to the trailing edge (forward flow). The airfoil design results from a performance compromise between forward and reverse airflow. For structural reasons, the thickness of the airfoil in proportion to its chord length may change along the blade radius. Thus, a family of airfoils has been designed that promote low-drag laminar flow with both forward and reverse flow, permit operation of the airfoil with reverse flow over a reasonable range of angles of attack, and achieve high lift with forward flow.
Spin Resistant Aircraft Configuration
US Patent:

International Classification:
B64C 21/00, B64C 21/10
US Classification:
2442001, 244198, 244200
Abstract:
A configuration and system for rendering an aircraft spin resistant is disclosed. Resistance of the aircraft to spinning is accomplished by constraining a stall cell to a wing region adjacent to the fuselage and distant from the wing tip. Wing features that facilitate this constraint include but are not limited to one or more cuffs, stall strips, vortex generators, wing twists, wing sweeps and horizontal stabilizers. Alone or in combination, aircraft configuration features embodied by the present invention render the aircraft spin resistant by constraining the stall cell, which allows control surfaces of the aircraft to remain operational to control the aircraft.
Spoiler System For Ground Effect Vehicles
US Patent:
5697468, Dec 16, 1997
Filed:
Sep 9, 1996
Appl. No.:
8/706747
Inventors:
William F. Russell - Westport CT
John Roncz - Elkhart IN
John Roncz - Elkhart IN
Assignee:
Flarecraft Corporation - Westport CT
International Classification:
B60V 108, B60V 111
US Classification:
180116
Abstract:
A ground effect vehicle wherein a flap coupled to a spoiler is provided on the wings in order to break lift when the craft starts to leave ground effect travel in order to avoid flight out of ground effect.
