摘要： A method and apparatus for varying the twist of a wing such that induced drag is minimized or reduced during cruise and lift is maximized or increased at least during takeoff and landings. In addition, variations in the twist may produce yawing and rolling moments. The twist amount is varied pursuant to the operating conditions, including those parameters used to determine the lift coefficient. The twist for reducing induced drag and/or improving lift may be employed by geometric or aerodynamic twist, including full span control surfaces used to provide roll control, high-lift and reduced induced drag. The twist may also be employed by twisting just a portion of the wing or the entire wing, either geometrically or aerodynamically.

摘要： A method and apparatus for varying the washout of a wing such that induced drag is minimized during a flight. The washout is varied pursuant to an optimized twist distribution that depends on the wing planform and an optimized twist amount which depends, at least in part, upon the operating conditions, including those parameters used to determine the lift coefficient. The optimum twist may be employed by geometric or aerodynamic twist, including full spanwise control surfaces used to simultaneously provide roll control, high-lift and minimum induced drag. The optimum twist may also be employed be twisting just a portion of the wing or the entire wing, either geometrically or aerodynamically.

摘要： A method and device for controlling and dampening undesirable vibrational movement within flexible linkage of a robot arm coupled to a movable, controlled joint and attached drive motor. The method includes the steps of providing position displacement and control in accordance with position and velocity feedback input. In addition, elastic deflection arising within the robot arm is detected and a time-dependent deflection signal proportional to the degree of elastic deflection is generated. A control algorithm develops deflection feedback signals for input to the robot arm which are approximately proportional to the deflection signal and its first two time derivatives, each multiplied by a gain whose value is selected to reduce further elastic deflection. This procedure is applied within flexible robot arm structure by incorporating elastic deflection detection components and by converting the detected deflection signal to deflection feedback signals for application to the drive system of the robot arm. Elastic deflections arising upon movement of the flexible arm structure are almost immediately nullified and the robot arm is allowed to reposition itself without interference from such undesirable forces and resultant robot arm movement.
