Abstract

531,445. Gas turbines. AKT.-GES. BROWN, BOVERI, & CIE. July 22, 1939, No. 21366. Convention date, July 27, 1938. [Class 110 (iii)] An air channel leading from a passage 7 in the blade wheel, is formed between the leading edge of the blade proper 1 and a spaced cap blade 2, The air emerges from the slits 4 and spreads over the blade surface. The cap blade may be formed of specially hard metal. The blades are welded together from 8 to 9 in the foot portion and at the tip 10 and the channel is closed by a plate 11. The cap blade may have a foot flange 12 corresponding to the. flange 5 of the main blade. The cap blade may be formed as shown in Fig. 5, or, it may co-operate with a groove 17, Fig. 7, formed in the leading edge of the. main blade.
