ABSTRACT: It has been known that maximum aerodynamic stresses occur in the
irppeller stages next to ii diffuserless scroll. In the past four years of operating
suIperchargers with such stages, -cases of shaft and web breaks, and cracks in the
cover disks are on record. Also, rivet-head crumbling has been observed.-
Metal fatigue has been mainly responsible for, those damages. Thepresent
article reports the results of tensometric tests of impellers conducted directly at
compressor'\stations. The aerodynamic stresses in, the impeller were measured

in the entire range of the compressor output, at 20, 30, 35, and 44 atm, and
7,950 rpm. An attempt was made to assess the rivet stresses by tensodetectors
mounted inside the rivet. These conclusions are reported: (1) The poor quality
of shafts and web-fittin-r surfaces is one of the reasons for shaft breakage;
I Ij
(Z) Under max output and minimum output conditions, considerable stresses are
set up in the impeller which may result in breakage due to fatigue; (3) The canti-
lever stiffness of the principal disk (web) has an important bearing on the dynamic
strength of the disk, rivets, and cover disk; (4) Cuts in the cover disk result in
an essential reduction of the aerodynamic forces acting an the Impeller. Orig.
art. has: 5 figures and 2 formulae.

ABSTRACT: Severa.11 orntrifugal compressor wheels have been subjected to tests with
peripheral speeds ..,f 290-300 m/~ec under simultaneous action of an air jet
(combined static dynamic stresses). It was found that the wheels tested failed--
in the same manner as the wheels in actual operation. The cracks I
