Unmanned aerial vehicle angular reorientation

摘要

A system comprising an unmanned aerial vehicle (UAV) having wing elements and tail elements configured to roll to angularly orient the UAV by rolling so as to align a longitudinal plane of the UAV, in its late terminal phase, with a target. A method of UAV body re-orientation comprising: (a) determining by a processor a boresight angle error correction value bases on distance between a target point and a boresight point of a body-fixed frame; and (b) effecting a UAV maneuver comprising an angular role rate component translating the target point to a re-oriented target point in the body-fixed frame, to maintain the offset angle via the offset angle correction value.

1. An unmanned aerial vehicle (UAV) comprising:
a processor having addressable memory, the processor configured to:
determine a body roll angle error based on a target location in a body reference frame and an orientation of the UAV in the body reference frame; anddetermine one or more aileron actuator commands based on the determined body roll angle error;wherein the processor of the UAV is further configured to bank-to-turn, and to transition to reorient in attitude based on an estimated range-to-go and an angular position of the target relative to the UAV.
