20080234881 | VERTICAL SPEED AND FLIGHT PATH COMMAND ALGORITHM FOR DISPLACEMENT COLLECTIVE UTILIZING TACTILE CUEING AND TACTILE FEEDBACK - A flight control system includes a collective position command algorithm for a lift axis (collective pitch) which, in combination with an active collective system, provides a force feedback such that a pilot may seamlessly command vertical speed, flight path angle or directly change collective blade pitch. The collective position command algorithm utilizes displacement of the collective controller to command direct collective blade pitch change, while a constant force application to the collective controller within a “level flight” detent commands vertical velocity or flight path angle. The “level flight” detent provides a tactile cue for collective position to reference the aircraft level flight attitude without the pilot having to refer to the instruments and without excessive collective controller movement. | 09-25-2008 |
20080249672 | ALTITUDE AND ACCELERATION COMMAND ALTITUDE HOLD ALGORITHM FOR ROTORCRAFT WITH LARGE CENTER OF GRAVITY RANGE - A flight control system includes an Acceleration and Attitude Command/Velocity Hold mode (AACVH) algorithm which blends attitude commands with acceleration commands. This blending determines a trim attitude for a given rotorcraft flight condition. | 10-09-2008 |
20080283671 | ENGINE ANTICIPATION FOR ROTARY-WING AIRCRAFT - A flight control system and method which determines an expected power required data in response to a flight control command of the at least one model following control law and utilizes the expected power required data to perform at least one action to control an engine speed. | 11-20-2008 |
20090012658 | CONTROL SURFACE FAILURE DETECTION FOR FLY-BY-WIRE AIRCRAFT - A flight control system which detects a failure of a flight control surface and performs at least one action in response to the detected failure. | 01-08-2009 |
20110168851 | AUTOMATIC TRIM SYSTEM FOR FLY-BY-WIRE AIRCRAFT WITH UNIQUE TRIM CONTROLLERS - A flight control system includes a controller which defines a controller displacement and a control surface which defines a control surface authority. A module operable to provide a displacement feel to the controller in response to a remaining portion of the controller displacement being greater than a remaining portion of the control surface authority and the module operable to re-reference a center of the controller displacement to equate the remaining portion of the controller displacement with the remaining portion of the control surface authority in response to the remaining portion of the controller displacement being less than the remaining portion of the control surface authority. | 07-14-2011 |
20130099064 | Methods And Systems For Providing Constant-Feel, Multi-Axis Tactile Cues - A system for adjusting tactile cues includes a controller having an axis and a cross-axis; an axis tactile cue generated in response to the position of the controller along the axis; a position scaling unit scaling a cross-axis controller position to generate a scaled cross-axis controller position; a force scaling unit scaling a cross-axis controller force to generate a scaled cross-axis controller force; a combiner combining the scaled cross-axis controller position and the scaled cross-axis controller force to generate an adjustment factor; and an adjuster adjusting the axis tactile cue in response to the adjustment factor to generate an adjusted axis tactile cue. | 04-25-2013 |
20130211634 | METHOD AND SYSTEM FOR PROVIDING SIDESLIP ENVELOPE PROTECTION - A system for providing sideslip envelope protection includes a processor for obtaining values of a sideslip envelope indicative of operating conditions of the aircraft along an axis and for estimating a sideslip angle along the axis from at least one operating condition; and a comparer for comparing the sideslip angle with the sideslip envelope to generate an output value, where the processor determines a maximum yaw rate from the output value and scales the maximum yaw rate to generate a scaled yaw rate. | 08-15-2013 |
20130338858 | METHOD FOR THREE DIMENSIONAL PERCEPTION PROCESSING AND CLASSIFICATION - An apparatus is described comprising at least one processor; and memory storing instructions that, when executed by the at least one processor, cause the apparatus to: organize items of raw data received from at least one sensor of a vehicle as a first data structure, organize classified data objects as a second data structure, and link at least one item of the first data structure to at least one object of the second data structure. | 12-19-2013 |
20140095001 | ALTITUDE AND ACCELERATION COMMAND ALTITUDE HOLD ALGORITHM FOR ROTORCRAFT WITH LARGE CENTER OF GRAVITY RANGE - A flight control system includes an Acceleration and Attitude Command/Velocity Hold mode (AACVH) algorithm which blends attitude commands with acceleration commands This blending determines a trim attitude for a given rotorcraft flight condition. | 04-03-2014 |
