摘要： According to one implementation of the present disclosure, a method for formation flight is disclosed. The method includes: during flight, arranging for a first aircraft to fly into a proximity range of a second aircraft; and determining first aircraft positioning based on power consumption data of the first aircraft, where the first aircraft positioning corresponds to power-reducing formation flight of the first aircraft.

摘要： According to one implementation of the present disclosure, a rotorcraft includes a fuselage, an airframe, a main rotor, first and second wings, and a wing rotation system. The wing rotation system may be coupled to the first and the second wings and includes a first drive shaft, a second drive shaft, and a uniform actuator. The first drive shaft may be coupled to the first wing for rotation around a central wing axis, the second drive shaft may be coupled to the second wing for rotation around the central wing axis, and the uniform actuator may be coupled between the first drive shaft and the airframe. Also, the wing rotation system can be configured to actuate rotation of the first and the second wings from a first direction to a second direction.

摘要： In one embodiment, a method is performed by a control computer. The method includes receiving a time series of control inputs in relation to a control axis of an aircraft, where the control computer causes actuation in response to each control input in the time series as the control input is received. The method also includes determining aircraft oscillation over a sample period corresponding to the time series. The method also includes evaluating information related to the determined aircraft oscillation using engagement settings associated with a control filter. The method also includes engaging the control filter responsive to the information satisfying the engagement settings, where the engaged control filter systematically attenuates future control inputs in relation to the control axis prior to actuation responsive thereto.

摘要： A vibration control system for a rotor hub provides vibration attenuation in an aircraft by reducing the magnitude of rotor induced vibratory. The system can include a force generating device attached to a rotor hub which rotates along with the rotor at the rotational speed of the rotor. Vibratory shear force is generated by rotating unbalanced weights each about an axis non-concentric with the rotor hub axis at high speed to create large centrifugal forces. The rotational speed of the weights can be a multiple of the rotor rotational speed to create shear forces for canceling rotor induced vibrations. The amplitude of the generated shear force is controlled by indexing the positions of the unbalanced weights relative to each other, while the phase of the shear force is adjusted by equally phasing each weight relative to the rotor.
