Abstract

1,068,280. Turbine blades. ROLLSROYCE Ltd. Dec. 10, 1965, No. 52633/65. Addition to 1, 034, 260. Heading F1T. In a modification of the blade for a gas turbine engine described in Specification 1,034,260, a baffle plate 40 is welded to the sleeve 23 mounted within the blade so as to reduce the flow of cooling air in the space 31 between the sleeve and the blade wall 32 to a low pressure region at the radially inner portion of the blade. The air in space 31 exhausts through a radially extending aperture 33 at the blade trailing edge. Air is directed to the interior of sleeve 23 from an annular dilution air duct (19), Fig. 1 (not shown) by scoops (27, 28), the blade forming a turbine nozzle guide blade in an annular combustion chamber (12). Part of this air flows through apertures (30) Fig. 2 (not shown), in sleeve 23 to enter space 31 and the remainder flows through radially spaced stub pipes (35) from the interior of the sleeve to the exterior of the blade wall 32 to act as dilution air for the combustion products. A partition 24 divides the interior of the sleeve. The blade may also be used in a steam turbine.
