Abstract: In an example, a propulsion system for controlling maneuvers of a tilt rotor aircraft includes one or more processors and a non-transitory computer readable medium storing instructions that, when executed by the one or more processors, cause the propulsion system to perform functions. The functions include making a determination that changing an orientation of the tilt rotor aircraft is necessary to perform an instructed flight maneuver. The functions also include causing, in response to the determination, a rotor of the tilt rotor aircraft to provide a thrust, thereby applying a torque to the tilt rotor aircraft that changes the orientation of the tilt rotor aircraft.

Abstract: A method includes generating, in a normal mode, an aircraft power setpoint and an aircraft pitch setpoint based on a desired airspeed setpoint and a desired altitude setpoint. The method includes transitioning from the normal mode to an underpower mode when the aircraft is unable to maintain the desired airspeed setpoint. The method includes setting, in the underpower mode, the aircraft power setpoint to a full power setting, generating, in the underpower mode, the aircraft pitch setpoint based on the desired altitude setpoint, and transitioning from the underpower mode to an underspeed mode when the aircraft airspeed is less than an airspeed threshold value while the aircraft power setpoint is set to the full power setting. The method includes maintaining, in the underspeed mode, the aircraft power setpoint at the full power setting and generating, in the underspeed mode, the aircraft pitch setpoint based on the desired airspeed setpoint.

Abstract: An aircraft control system includes a longitudinal control module, an engine torque control module, and an actuator control system. The longitudinal control module is configured to generate a desired torque value and a desired elevator position value for an aircraft based on a desired airspeed value, a desired altitude value, an actual airspeed value, and an actual altitude value. The engine torque control module is configured to generate a desired power lever position value based on the desired torque value and a measured engine torque value that indicates a measured engine torque in the aircraft. The actuator control system is configured to generate a power lever position command and an elevator position command for the aircraft based on the desired power lever position value and the desired elevator position value.

Abstract: A method, apparatus, system for tracking an object, the method. A region of interest in an image pair is determined based on a bounding box determined for the object in the image pair. A mask based on the region of interest is applied to the image pair. The mask masks out portions of the image pair outside of the region of interest to form masked images. Intensity averaging is performed on the masked images to detect a set of pixels having a greatest intensity in the masked images. The set of pixels in the masked images is a set of common pixels in the masked images in which the set of common pixels is assumed to have a same location in both of the masked images. A three-dimensional position of the object is determined using the set of common pixels.
