Abstract

613,667. Turbine and compressor blades. ENGLISH ELECTRIC CO., Ltd., and COWLIN, F. J. June 25, 1946, No. 18974. [Class 110 (iii)] The rotor disc has a gap in its circumference for the radial insertion of straddle-type blades preparatory to shifting them circumferentially into position, and the gap is serrated to match a complementarily serrated blade adapted to be laterally inserted therein to close the row of straddle blades. The straddle blades 2, 3 next to the gap 5 are similar to the ordinary straddle blades 1, but their roots are provided with additional serrations 6, 7 identical with the serrations in the flanks of the gap. The root of the closure blade 4 extends the full width of the disc periphery without any recess for a straddle seat. To allow of the lateral insertion of the blade 4, its trailing edge 4a is cut short, so as not to overlap with the leading edge of the adjacent blade 3. ,
