Abstract

941,342. Shafts; bearings; controlling boundary layer flow. R. BIRMANN. Aug. 29, 1961, No. 31058/61. Headings F2A, F2R and F2U. [Also in Division F1] In the turbine-driven supercharger shown in Fig. 1, shaft extensions 70, 72 form the inner races of bearings 78, 98 and are carried in slightly tapered bores 74, 76 in the main shaft. Increasing shaft deflection causes the point of contact of each shaft extension with the corresponding tapered bore to shift outwardly, thereby rapidly increasing the deflection stiffness of the shaft. In addition, the bearings are flexibly mounted in polygonal leaf spring elements 80, 100. These two features render the rotor assembly self-balancing and eliminate critical speeds and other vibration phenomena. The turbine rotor blades 57, Fig. 7, are provided with bulbous inlet edges 120 so that the area of the flow passage between adjacent blades decreases in the direction of flow, the decrease being most rapid at the inlet edges. The resultant increase in relative velocity through the rotor 56 produces a pressure gradient which counteracts the adverse pressure gradient caused by centrifugal forces and tending to cause rapid growth of boundary layers. Specifications 941,343 and 941,344 are referred to.
