摘要： A vane includes a composite airfoil having a dovetail root extending chordwise between or near leading and trailing edges of the airfoil. The root is connected to the airfoil and is slidably received in a dovetail slot in an inner vane mount. The dovetail slot has a triangular slot cross section and a flat slot bottom and flat slot pressure and suction side crush faces corresponding to pressure and suction sides of the airfoil. The root has a triangular root cross section, a flat root bottom, and flat dovetail root pressure and suction side crush faces. A biasing means urges the root bottom of the dovetail root away from the slot bottom and presses and preloads the dovetail root pressure and suction side crush faces against the slot pressure and suction side slot crush faces.

摘要： A vane includes a composite airfoil having chordwise spaced apart forward and aft dovetail feet at or near leading and trailing edges of the airfoil. Each foot includes a shank connecting a dovetail root to an airfoil base and each root is slidably received in a dovetail slot in an inner vane mount. The dovetail slot has a triangular slot cross section and a flat slot bottom and flat slot pressure and suction side crush faces corresponding to pressure and suction sides of the airfoil. The dovetail root having a triangular root cross section and a flat root bottom and flat dovetail root pressure and suction side crush faces. A biasing means urges the root bottom of the dovetail roots away from the slot bottom and presses and preloads the dovetail root pressure and suction side crush faces against the slot pressure and suction side slot crush faces.

摘要： A vane includes a composite airfoil having a single dovetail root extending chordwise between or near leading and trailing edges of the airfoil. The root is connected to the airfoil and is slidably received in a dovetail slot in an inner vane mount. The dovetail slot has a triangular slot cross section and a flat slot bottom and flat slot pressure and suction side crush faces corresponding to pressure and suction sides of the airfoil. The root has a triangular root cross section, a flat root bottom, and flat dovetail root pressure and suction side crush faces. A biasing means urges the root bottom of the dovetail root away from the slot bottom and presses and preloads the dovetail root pressure and suction side crush faces against the slot pressure and suction side slot crush faces.
