Zusammenfassung:An airfoil arrangement for a gas turbine engine may include a clearance device using a shape memory alloy, the clearance device movable to provide a clearance between an airfoil and one or more other components of the gas turbine engine. The gap device may be formed as part of a fan blade. The arrangement may be configured to reduce the total weight and size of the gas turbine engine. 一种用于燃气涡轮发动机的翼型件布置可包括使用形状记忆合金的间隙装置，间隙装置可移动以在翼型件和燃气涡轮发动机的一个或多个其他部件之间提供间隙。间隙装置可以形成为风扇叶片的一部分。该布置可被构造为减少燃气涡轮发动机的总重量和尺寸。
