Patent number: 11900824Abstract: The aircraft threat envelope protection system employs a threat envelope data structure in a computer-readable medium that stores at least one trigger condition for each of a plurality of different types of threats associated with the aircraft, and modeled using a common schema. A processor computes plural different projected trajectories representing different possible aircraft paths through spacetime. The processor associates at least some of the plurality of the threats to specific trigger points in spacetime along each of the projected trajectories. The processor will deprecate ones of the projected trajectories when they are deemed not viable to recover from a threat. The processor initiates an aircraft protective response when all projected trajectories but one have been deprecated and the aircraft is within a predetermined proximity to the closest trigger point in spacetime along the non-deprecated trajectory.Type: GrantFiled: April 3, 2023Date of Patent: February 13, 2024Assignee: GULFSTREAM AEROSPACE CORPORATIONInventors: Kevin Prosser, Thomas Landers, Abhishek Vaidya, Alborz Sakhaei, Blake Finlayson

Patent number: 11592839Abstract: The processor supplies flight commands to the flight control system by selectively blending pilot input with control signals from the autopilot. The processor generates a projected recovery trajectory through successive iterations, each beginning at the current aircraft location and using a recovery constraint selectable by the processor to influences a degree of flight aggressiveness. A detection system that identifies and invokes a state of threat existence if a threat exists along the projected recovery trajectory. The processor during threat existence in a first iteration commands an initial soft recovery, with permitted blended pilot input. If the threat exists on subsequent iteration, the processor commands a more aggressive recovery while attenuating blended pilot input.Type: GrantFiled: August 27, 2019Date of Patent: February 28, 2023Assignee: Gulfstream Aerospace CorporationInventors: Kevin Prosser, Thomas Landers, Alborz Sakhaei, Abhishek Vaidya, Blake Finlayson
