Spin Resistant Aircraft Configuration

View page
US Patent:
20140021302, Jan 23, 2014
Filed:
Jul 19, 2013
Appl. No.:
13/946572
Inventors:
Jon Karkow - Tehachapi CA, US
John Roncz - Elkhart IN, US
Dieter Koehler - Powell Butte OR, US
Len Fox - Bend OR, US
David Lednicer - Redmond WA, US
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.

Helicopter Blade Airfoil

View page
US Patent:
RE335894, May 14, 1991
Filed:
May 17, 1990
Appl. No.:
7/526251
Inventors:
David A. Lednicer - Redmond WA
Stephen J. Owen - Redmond WA
Assignee:
United Technologies Corporation - Hartford CT
International Classification:
B64C 2746
US Classification:
416223R
Abstract:
A family of airfoil cross sections, termed SC21xx, for use in a helicopter blade is disclosed. The airfoil (36) achieves maximum lift performance equivalent to prior art airfoil configurations without incurring increased aerodynamic drag at high velocities. The airfoil (36) was developed by thickening and drooping the leading edge region (38) of the prior art airfoil (30) improving lift in the leading edge region (38) and delaying the formation of sonic shock waves at high velocities.
