Patent number: 10351225Abstract: A method for position hold override control of an aircraft includes determining, by a processor, that a position hold mode is enabled to hold the aircraft at a substantially fixed position with respect to a target. The processor receives a control input indicative of a commanded change in acceleration of the aircraft as an override of the position hold mode. The processor determines an acceleration command based on the commanded change in acceleration. The acceleration command is adjusted as an adjusted acceleration command responsive to a non-linear scheduled translational rate command based on feedback of a commanded velocity of the aircraft. An update to the commanded velocity of the aircraft is generated based on the adjusted acceleration command.Type: GrantFiled: March 4, 2016Date of Patent: July 16, 2019Assignee: SIKORSKY AIRCRAFT CORPORATIONInventors: Steven E. Spoldi, Alex Faynberg, Stephen Kubik, Donald T. Ream, John Rucci, Stephen C. McCulley, Christiaan Corry

Patent number: 7742846Abstract: A method of transitioning from a complex response flight state to a ground operation control state. Pilot intent is determined through collective position information to control the transition. An independent cockpit switch activates an emergency surface contact transition function for use with a fly-by-wire (FBW) flight control system. Once the surface contact transition function is active, FBW control laws transition from a fully augmented flight state, through an augmentation deactivation state and into the surface contact state.Type: GrantFiled: June 2, 2006Date of Patent: June 22, 2010Assignee: Sikorsky Aircraft CorporationInventors: Todd M. Fanciullo, Paul Morphy, Lorren Stiles, Alex Faynberg
