Abstract

359,350. Gas turbines. SKODA WORKS, PLZEN, 37N, Jungmannova, Prague, and KALABEK, V., 15, Namesti Ceskych Bratri, Pilsen, both in Czecho- Slovakia. Feb. 20, 1931, No. 5461. Convention date, March 3, 1930. [Class 110 (iii).] The discs 1, 2 forming a gas turbine rotor are connected at the periphery by members, such as the roots of the blades 3, having projections 4, 9 locking into grooves in the discs. The discs are not perforated to take securing bolts or rivets. The discs may also be connected by members 12 at the hub. Cooling fluid is passed through the channel 7 to the hollow blades 3. In a modification the blade roots are serrated, and in a further modification the blade spacers comprise the locking means.
