    摘要： A method and apparatus (110) for controlling movement of an aircraft. An aerodynamic function desired for controlling the movement of the aircraft (106) at a particular altitude is identified. The aerodynamic function identified is part of a group of aerodynamic functions (122) used to control the movement of the aircraft (106) at a number of different altitudes (104). A group of inflatable blades (120) is filled with a fluid (116) to a pressure that corresponds to the aerodynamic function. The group of inflatable blades (120) at the pressure has a shape (208) and a group of dimensions (210) that provide the aerodynamic function.

    摘要： A system and method for pressure based load measurement of the blades of a wind turbine are provided. The system and method measure at least one pressure differential on an airfoil and determine at least one aerodynamic load associated with the at least one pressure differential. The determined at least one load is used to modify characteristics of the airfoil to increase efficiency and/or avoid damage. The determined at least one aerodynamic load may be further utilized to balance and/or optimize loads at the airfoil, estimate a load distribution along the airfoil used to derive other metrics about the airfoil, and/or used in a distributed control system to increase efficiency and/or reduce damage to, e.g., one or more wind turbines.

    摘要： An airflow generation device of an embodiment has a main body and a voltage application unit. The main body has a base formed of an insulating material and provided with a first electrode and a second electrode. The voltage application unit generates an airflow by applying voltage between the first electrode and the second electrode. Here, the main body is formed to include a portion which gradually decreases in thickness from a center portion to an end portion. The idea is to avoid leading edge flow separation by generating a plasma locally.
