Direct lift, drag and heading improvement for multi-lift aircraft control system
专利汇可以提供Direct lift, drag and heading improvement for multi-lift aircraft control system专利检索，专利查询，专利分析的服务。并且A single load is suspended from vertical cables extending beneath each of two direct lift type of aircraft, the cables being separated by a spreader bar. A trailing, slave aircraft flys behind, above, and to one side of a leading, master aircraft, with the spreader bar extending at an angle to the heading of the aircraft, in a plane below them. The lead pilot control provides overall, or outer loop control of the lead aircraft, and the controls of the lead aircraft are electromechanically coupled to operate the controls of the trailing aircraft, whereby the lead pilot controls the outer loop of both aircraft. The inner or stability loop of the controls of each aircraft are modified so as to utilize inputs from the inertial system of the related aircraft and inputs relating to the manner in which the load extends below the aircraft, to both stabilize the load with respect to each aircraft, and to maintain the trail aircraft in a proper position with respect to the lead aircraft and the load. Specifically, the cables from each aircraft supporting the spreader bar are maintained substantially perpendicular with respect to the spreader bar thereby to maintain substantially equal loading of each aircraft; pitch and roll inertial sensors in each aircraft, and the angle of each cable with respect to its aircraft in both the pitch and roll directions, are utilized in the respective aircraft to stabilize that aircraft with respect to the load, thereby to prevent pendular oscillations of the load; the heading of the load itself and of each aircraft, together with desired formation inputs, are utilized to control the heading of the trailing aircraft, and to provide pitch and roll inputs to control relative position of the trailing aircraft with respect to the leading aircraft so as to maintain a desired formation in flight.，下面是Direct lift, drag and heading improvement for multi-lift aircraft control system专利的具体信息内容。
