Abstract: 719,061. Gas turbine plant; axial-flow compressors. UNITED AIRCRAFT CORPORATION. March 19, 1951 [June 21, 1950; July 27, 1950], No. 6500/51. Classes 110(1) and 110(3) In an axial-flow gas turbine plant having an air compressor with co-operating rotor and stator blades, some or all of the blades have modified end portions which increase the axial component of the gas flow near the wall or boundary of the gas flow path with respect to the axial component of the gas flow more remotely spaced therefrom. The vane shown in Fig. 2 is an inlet guide vane of the axial-flow compressor of a gas turbine plant. The mid-portion 32 of the vane is cambered so that air is directed on to the first row of rotor blades at the desired angle. The end portions 28, 30 of the vane are of substantially symmetrical cross-section as shown at 34, 36 so that air flows over these portions in an approximately axial direction. The axial component of the air flowing near the walls 16, 20 is therefore greater than that of the air flowing over the cambered part of the vane. In the embodiment shown in Fig. 3 the inlet guide vane 38 is supported solely by struts 40, 42 while in Fig. 4, the guide vane 44 is supported at one end only by a strut 46.

An arm 13 pivoted at 14 is connected to the arm 10 by a spring under tension, and the arms 10, 13 are pivoted to a rod 17 fitted with a head 18. A prong 8 is secured to the housing and is pointed at 9. The housing is completed by a cover 6. In use, the handgrip 7 is taken in the right hand, and a thumb lever 19, operated to move the head apart from the prong 8. Five thicknesses of cloth, at the outside of the bolt, are then inserted between the parts 8, 18. This preliminary operation determines which of the spaces A, B, C, &c. between the concentric circles on the scale is to be followed subsequently. The indication is given by observing during this operation, which of such spaces has its first dot on the edge of the pointer. The prong is now inserted at the core and the thickness of the whole bolt of cloth callipered, the pointer will now indicate in the space first determined the total number of folds. In a modification for ribbon rolls, four thicknesses are first measured, and with a standard core these represent one yard. The scale is therefore graduated in yards. In this form the bar 17 is guided, and is moved by a single spring-pulled arm.
