Gas turbine engines generally comprise a first-stage nozzle guide vane. Temperatures in a trailing-edge area of the suction-side wall of such vanes can exceed material and coating limits. While an insert can be used to form passages for cooling air to flow along the inner surfaces of the vane walls, design constraints prevent the insert from extending beyond a certain point into the trailing edge of the vane. Accordingly, a fin is disclosed for insertion downstream of the insert. By eliminating sudden expansion beyond the downstream end of the insert and maintaining the speed of the cooling air across the trailing-edge area of the suction-side wall, the fin improves the cooling coefficient for the trailing-edge area, so as to prevent or reduce excessive temperatures in the trailing-edge area.

Golf club head

Wood-type golf club head

Putter head

A putter-type golf club head is provided having enhanced moment of inertia and alignment characteristics. The putter head includes a front body and a weight body. The weight body includes a central weight section extending rearwardly from the front body a prescribed distance to a rear weight section. The putter head is configured such that the rear weight section has a width less than the width of the front body and greater than a width of the central weight section. Thus, both the longitudinal and lateral moments of inertia are improved to offer greater forgiveness and increased accuracy during putts. The central weight section may include at least one and more preferably two elongated, high-density elements that are visible on a top surface of the sole between the front body and the rear weight section. The visibility of the elongated elements, with optional parallel markings on a top surface of the golf club head, also act as alignment aids to the golfer.
