摘要： Provided are computer-implemented methods for autonomously controlling an aircraft with vertical take-off and landing capabilities and folding wings that includes controlling a plurality of thrust producing components of an aircraft to cause the aircraft to rise vertically when wings of the aircraft are in a first folded configuration, where when the wings of the aircraft are in the first folded configuration, a leading edge of each wing is oriented in a vertical direction setting motor controller gains based on the wings of the aircraft being in the first folded configuration, and causing the aircraft to align with a direction of airflow when the wings of the aircraft are in the first folded configuration, and controlling thrust producing components and control surfaces and internal articulation mechanisms of the aircraft to cause the aircraft to transition from folded wing configuration to unfolded wing configuration. Systems and computer program products are also provided.

摘要： An aircraft center of gravity and fuel level advisory system connected to the aircraft's fuel tank gauges and operated by an aircraft personnel. The system provides the aircraft's personnel with real time display of the aircraft's center of gravity and a signal when forward and aft center of gravity limits are approached. The system provides a means for a crew member to select a fuel level for a tank or set of tanks and when the actual fuel level approaches the selected value, the system will alert the crew member.

摘要： Aircraft weight and balance computer apparatus processes sensor outputs to generate an electrical signal that is proportional to aircraft gross weight at the time take-off thrust is initially applied to the aircraft on the runway and continually updates the weight signal when airborne to account for burn off of fuel or other weight loss and also provides a measure of the location of the aircraft center of gravity position. This is achieved by computing the aerodynamic forces on the aircraft in its longitudinal plane and the thrust generated by the engines and relating these computations to the corresponding acceleration components measured by a pair of linear accelerometers that are mounted orthogonally in this longitudinal plane.

摘要： The present application provides an unmanned aerial vehicle (UAV) for a long duration flight. An exemplary UAV may include a UAV body assembly. The UAV may also include a flight control system (FCS) coupled to the UAV body assembly. The UAV may further include a motor coupled to the UAV body assembly at one end and coupled to a propeller at the other end. The FCS is communicatively connected to the motor.

摘要： A computer-implemented method for determining center of gravity of a tiltrotor aircraft includes storing a multi-dimensional matrix mapping multiple tiltrotor aircraft parameters to a plurality of three-dimensional (3D) centers of gravity of the tiltrotor aircraft, where each 3D center of gravity includes a respective longitudinal center of gravity, lateral center of gravity, and vertical center of gravity. The method includes receiving input signals from corresponding on-board sensors, where the input signals represent characteristics of the tiltrotor aircraft, determining tiltrotor aircraft parameters from the input signals, identifying, from the multi-dimensional matrix mapping, a longitudinal center of gravity, a lateral center of gravity, and a vertical center of gravity that corresponds to the determined tiltrotor aircraft parameters, and providing the identified longitudinal center of gravity, the identified lateral center of gravity, and the identified vertical center of gravity in response to receiving the input signals.
