摘要： An aircraft control system for an unmanned aircraft comprising a forward propulsion system comprising a forward thrust engine and a vertical propulsion system comprising a vertical thrust engine. The aircraft control system may include a controller comprising an input coupled to receive a velocity signal indicating a determined amount of forward velocity and being configured to generate a pitch angle command associated with the determined amount of forward velocity; a splitting block comprising an input to receive the pitch angle command and being configured to generate a second pitch angle command and a forward thrust engine throttle command based on a bounded pitch angle for the unmanned aircraft; and an output coupled to provide the second pitch angle command to the vertical propulsion system and the forward thrust engine throttle command to the forward propulsion system.

摘要： A method of controlling forward thrust of an aircraft includes receiving a first pitch angle command; generating a second pitch angle command and a forward thrust engine throttle command based on a bounded pitch angle for the aircraft; comparing a determined bounded pitch angle for the aircraft to the pitch angle corresponding to the first pitch angle command; generating a reduced pitch angle command so the resultant aircraft pitch angle does not exceed the bounded pitch angle; and generating the forward thrust engine throttle command based on the reduced pitch angle command.

摘要： A vertical take-off and landing aircraft includes a fixed wing airframe having opposed left and right wings extending from left and right sides, respectively, of a fuselage having opposed leading and trailing extremities and an empennage located behind the trailing extremity. Four fixed, open and horizontal, vertical take-off and landing (VTOL) thrust rotors are mounted to the airframe in a quadrotor pattern for providing vertical lift to the aircraft, and a vertical, forward thrust rotor is mounted to the trailing extremity of the fuselage between the trailing extremity of the fuselage and the empennage for providing forward thrust to the aircraft. The four VTOL thrust rotors are coplanar being and operating in a common plane that is parallel relative to, and being level with, top surfaces of the left and right wings in and around a region of each of the four VTOL thrust rotors.

摘要： An aircraft, such as an unmanned aircraft, can include a forward propulsion system comprising one or more engines and one or more rotors coupled to a corresponding engine; a vertical propulsion system comprising one or more vertical propulsion engines and one or more corresponding rotors coupled thereto; a sensor package comprising one or more sensors to detect an operating parameter of the aircraft. It may further include an automatic recovery system that includes an input coupled to the sensor package; an output coupled to an aircraft controller; a processor to monitor one or more operating parameters of the aircraft, detect a failure of the forward propulsion system based on the operating parameters, and transition the aircraft to the vertical propulsion system for landing.
