TITLE: Cement Models for the Manufacture of Dies
PERIODICAL:. Mashinostroltell, 1960, No. 12, pl. 36
TEU: Generally the complex profile of the working surface of forging dies
for blades is machined on copying milling machines according to wooden model
templets. These models lose their geometrical i3hape rather quick because of
temperature fluctuations and the effects,of air moisture In the storing rooms.
Instead of having model sets for forging dies made of wood, the manufacture of
which takes a model maker of the 6th grade some seven days, the Leningradskly
metallicheskiy zavod (Leningrad Metallicheskly 'Plant) produces 'there models from
cement. The templets used for the cement-model makirA serve also for the checking
of the die shape during the milling operation and fitting work. At the beginning
a frame work is manufactured from templets, distance sleeves and gaging pins.
Braces are mounted on the sides of the framework, tightened by wedges and cramps.
Then diluted construction gypsum is filled into the framework, the side walls of
which are removed after the solidification of the gypsum. The profile of the die

model is then shaped subsequently between every pair of neighboring templets, the
surplus gypsum being cut away flush with the templet profile. Those parts of the
profile for which the framework does not provide a templet is done by surface
gaging. The ready gypsum mold is covered with a thin nitro-lacquer coating and
greased with stearin diluted with kerosene in order to prevent the gypsum from
sticking to the cement. Side walls are mounted to the ready mold and the cement
is poured in. The process of the cement model setting takes 3-4 days. The cast
cement model-templet has a smoother and better surface than the wooden ones, while
its manufaoture costs by 2-2.5 times less than that of wooden model-templets.

TITLE: Methods of Increasing the Efficiency of Turb4e Stages
with Short Blades
PERIODICAL: Teploenergetika, 1960, Nr 2, pp 18-24 (USSR)
ABSTRACT: The efficiency of the high-pressure parts of large
turbines having fixed and runner blades or improved
profiles and provided with good internal glands and seals
reaches 78 to 80%. 'Further improvements in profiling
are not likely to give much better efficiency, as
modern blades already have very low profile-losses,
However, the efficiency of intermediate high-pressure
stages can be appreciably increased by special profiling
of the fixed blades in the meridioaal plane and by
using runner blades with diffuser channels. Meridianal
profiling isnow being developed to give stages of
constant reaction. In high-pressure stages this problem
is best solved by trying to reduce the end losses. In
order to reduce the end :LoSBes in fixed blades, it is
Card 1/6 necessary to reduce the velocity on sections of maximum

channel curvature where secondary flows are most marked.
This ensures turbulent I-low and so reduces the thickness
of boundary layers on the backs of the blading and on
the upper and lower walls of the channel. This is
accomplished by profiling the channels along their height
(profiling in the meridional plane). The profiling may
be symmetrical with strfLight or curved faces or
asymmetrical with straight or curved generating lines.
Asy=etrical profiling Eiakes it possible both to reduce
the end losses and to reduce the radial pressure gradient.
The present article givos test results on blading with
asymmetrical profiling over the height, both with the
blades mounted in straight rows and on rotors. Fig 1
gives graphs of the loss distribution over the height
of a straight row of blades with different shapes of
the upper rim. It will be seen that the best results
are obtained with asymmetrical profiling beyond the
position where the curvature of the channel is greatest.
The reduction in fixed-'blade losses by the use of

graph of pressure distribution across the.profile given
in Fig 2. it is.al6o, pointed out that in the blading
with asymmetrical profiling the point Of minimum pressure
is displaced somewhat in the direction of flow. Hence
the length of the turbulent section and the pressure
gradients in it are somewhat reduced. This has the effect
of reducing the profile losses. The loss-coefficient
curves plotted in Vis 3 clearly show the advantages of
blades with asymmetrical profiling over the height,
particularly forshort blading. The effect of this
special profiling is greater when the blades are mounted
on a rotor-because-the losses at,the blade roots are
particularly reduced, thereby helping to.equalise the
velocity distribution. The best shape of profiling is
then,considered. 'Graphs of loss reduction as a function
of profiling compression, plotted in Fig 4, indicate
that the optimum amount of compression depends on the
blade length. The shape of the compression curve may
be based on calculation of the flow potential in the

different degrees of-~compression is given in Fig 5, and
calculated and experimental velocity distributions over
a straight arrangement of blading caps TS-2A is given
in Fig 6. It will be seen that agreement between theory
and experiment is good. Tests on intermediate-stage
fixed blades with diffuser inlets showed that under
static conditions their use does not; influence the
effect of asymmetrical profiling over the height. Test
results are plotted in Fig 7 and it is considered that
the use of fixed blades with a complicated shape of
outer rimincrea8es the efficiency of intermediate
stages with short blades, Further information about
the use of fixed blades with asymmetrical profiling
was obtained by testing groups of stages in the experi-
mental steam turbinti of the Moscow Power Institute.
All stages have the same mean diameter of 400 mm; the
other dimensions are) tabulated. Tests were made on
six stages of various blade lengths. Some were made
with fixed blades profiled over the height and some

Methods of Increasing the Eff4

The tests covered a fairly wide range of velocity ratio
and heat-drop. The results, plotted in Fig 8, indicate
that at optimum velocity ratio the stage with profiled
blades has,2% highe3~ efficiency with a blade length of
25 mm, and 3% higher with a length of 15 mm. The
relative increase in efficiency by the use of
asymmetrical profiling is 2.5% and 3.7 to 4% respectively.
Asymmetrically-profiled blades continue to offer
advantages when operation is not at the designed
conditions as is explained by reference to other
curves on kig 8.. Important results were obtained on
measuring the reaction in the blade root and tip
sections. The use of asymmetrical -profiling reduces
the variations in static pressure distribution over the
pitch in the sections. As will be seen from the graphs
plotted in Fig 9 there was also a marked reduction in
the difference between the reactions at the root and tip.
The value of the outlet area of the guide vanes may be
calculated from formula (1). An approximate method is
Card 5/6 given for calculating the asymmetrical profiling,, using

Eq (2). It is conaluded that asymmetrical profiling of
the fixed blades aC;rOSB the haight helps to give stages
with constant reaction over the radius,, In stages
with very short blading any profiling of the channels
over the height undertaken to reduce the difference in
reaction should also be designed to reduce the end
losses. The method. of asymmetrical profiling that is
proposed in this article solves these two problems.

PERIODICAL: Teploenergetika, 196o~ Nr 8, PP 51-56 (uss
ABSTRACTs Work published in Teploenergetika, 1956, Nr 6, and by
Nippert in Germany in 1929 has shown that if the angle
through which a flow turns in a channel is great and the
static pressures at inlet and outlet are not very
different, the losses due to secondary flow in curved.
ducts and in short blades are not minimum when the flow
is steadily constricted. Nippert showed that when the
flow is turned through a large angle, the use of
expansion followed by constriction of tbe ducts between
the blades greatly reduces the terminal losses. The
theoretical problem is very complicated and it is best
to determine the optimum velocity distribution by
experiments. Tests were made on the Moscow Power

different shapes with blade type TR-2A are shown
in Fig 1. The results are discussed and it is
concluded that there are three causes of the reduced
terminal losses in blades with expanding and constricting
channels, namelyl the direction of the flow is altered
at the lower mean speed; at the outlet section where
secondary flows are intensified, the channel is
constricted so that longitudinal pressure gradients
are increasedi in cross-section the length of the
expanding section of the chanz 'iel on the back of the
blade Is reduced as the point of minimum pressure is
displaced in the dire-:~tion of the flow, As will be seen
from Fig 2. absolute values of loss factors in blades
with channels of this type are reduced and, moreover,
the distribution of losses over the height and pitch is
more uniform. Gxaphz showing the relationship between
the loss factor of the blading, the height and the angle
of inlet are shoum in Fig 3 for various kinds of blade.

height are shown in Fig 4; curves of the relationship
between the loss factoro the pitch and the ratio of
the maximum to the inlet section are shown in Fig 5.
Optimum geometrical parameters for blades of group Ak
are given in Table 3. It will be seen from Fig 5 and
Table 3 that small variations in the ratio of the
maximum to the inlet section do not appreciably affect
the losses, the comparatively marked i-acrease in
losses at low relative pitch occ;urs because the channel
Is of less suitable shape. The influenr-e of flow
conditions on the efficiency of class Ak blading may
be assessed from the graphs of Fig 6 and Fig 7.
Fig 6 shows the influence of inlet angle.1 it will be
seen that although the inlet losses do not vary much
with inlet angle ranging from 25 to 35t the losses are
less with blades- Ak than with blades A. The influence
of compressibility and Reynolds number on losses in the
two types of blading is shown in Fig ? and it is shown
Card 4/6 that compressIbility does not have an appre-,iable

influence.on the losses up to Mach 1. Tests made
with blades B and Bk ar 'e shown in Fig 7b and it
will be seen that at slightly supersonic speeds the
presence of an expanding section beyond the inlet has
a favourable effect on the losses. it is concluded
that in blades where the flow is turned through large
angles, the terminal losses may be appreciably reduced
by using blades group Ak and Bk with expanding and
constricting channels. The simplest way of making these
blades is to cut back the concave surfaces of blades A
and B which are widely used in turbines. The best
amount of expansion of the inlet section depends mainly
on the angle through which the flow is turned and the
relative height of the blading. Blading of the type
described should.be.used with relative heights less than
2 to 3 and wher. the flow is turned through angles
greater than 120 to 125*. The use of these blades
together with guide vanes type Am (having asymmetrical

"discharge edges of blades". It is assumed that change in cu
across the width of the blade B is linear over the centre line of
the channel, The law of change of the radius of curvature of the
current lines in the gap may be determined approximately in the
general case by solution of the equations of continuity written for
three sections; before the guide vanes, in the gap, and beyond the
stage. It is shown that foir turbine-stages In which clu is
considerably greater than elz the influence of the curvature of

For compressor stages which are not profiled for constant

The coefficient K depands on many factors and mainly on the
gradient of static presaure along the radius and height of the
blade. For long blades- K is nearly unity, when d/f> 8,
K - 1.3 - I.4, and for jitages with d/e less than 8, K = 1.5-1.7-
Further correction in thesevalues may be required when
experimental data are accumulated. Values calculated by formula
(17) have been compared with experimental data for certain types of
stages with meridianal profiling and sloping edges and it will be
seen that agreement is particularly good for stages for which
d/4'> 8.4. Another important matter is the correct selection of
blade twist. The effectiveness of root and peripheral sections of
guide and runner blades of stages with low values of d/f is low.
Accordingly it is advisable to select the smallest possible
discharge angle al in the blade root and peripheral sections, so
as to reduce the flow in these sections. In stages with low values
of d/.e and high super--critical pressure-drops it is of interest A/
to use blades with sloping discharge edges. However, it is not
desirable fully to equalise the reaction over the blade height,
because it is then practically impossible to achieve axial flow
discharge beyond the stage and so the di3charge velocity losses rise.

On the design of turbine stages with... E194/E155
On the other hand, large angles of slope cause considerable increase
in profile losses and losses in peripheral sections. This point is
discussed in relation to certain test results. As the angle of
slope of the blades is increased, the difference between the
reactions at the blade tip and at the root is much reduced. With
the particular stage geometry considered, it falls to zero when
Y = 25-300. It is concluded that by allowing for the three
factors; curvature of the flow lines, expansion of the flow path
and slope of the discharge edges; and also by introducing an
experimental coefficient into Eq. (17), the accuracy of
calculation of stage parameters with long blades is appreciably
increased.

TITLE: The influence of blade height on certain
characteristics of single-row turbine stages
PERIODICAL: Energomashinostroyenlye, no.1, 1962, 6-9
TEXT: This article deiscribes work done in the Kafedra parovykh i
gazovykh turbin (Steam- and Ciao-Turbine Department) of the MEI.
The notation used in the article is shown in Fig.l. The stages
tested had'a mean diameter dc*p= 400 mm and the value of the height
Ll ranged from 48 to 11) mm, The clearances had the following
valuess 61, 1.2 to 1.5 mm; 62, 3 mml 63, 0.6 to 0.8 mm;
64, 1.5 mm. There were no equalizing holes in the disc. The
stages were built up by combining a number of different types of
runter and nozzle bladea so that the effective blade length and
other characteristics-could be altered. Curves are plotted of
stage efficiency and reaction as functions of the velocity ratio of

u/co for stages having different blade lengths. The influence of
blade to nozzle area F2/Fl on efficiency and the influence of the
enclosed axial clearance 62 and of the Reynolds number with
different blade lengths are also plotted. It is concluded that
meridianal profiling of nozzle blading in stages with a height of
10 to 25 mm gives an appreciable increase in stage efficiency, of
the order of 2 to 396. In stages with this kind of profiling, there
is almost no difference between the reaction at the blade tip and
that at the blade roo t. When the blades are short, the efficiency
falls off more rapidly than is the case with long blades if the
velocity ratio is not of the optimum value, within the range of
U/cc. = 0.4 to 0.58. Other things being equal, the mean stage
reaction depends very much on the height of the bladts, and it
increases as the blades become shorter. When the blades are short
the area ratio F2/Fl has less influence on the stage efficiency
than when they are long. The magnitude of the optimum relative
enclosed axial clearance 62 diminishes as the blades are
shortened. The Reynolds number was found to have an influence on
the optimum value of this clearance for stages with short blades.

a rotor diameter of 130 rr,,m, a rotor width of 12 mm and a flow

Energy losses in 16 cross-:sections around the periphery were
ineasured togetherwith the flow angles and static pressures. The
static pressures were also measured in the entry sock6t and along
the mean volute line. Conclusions: the design procedute put
forward permits the determination of the volute geometry and the
behaviour of the volute flow under non-design conditions. The flow
exit angle from the bladeless assembly depends on the flow
velocity even at sub-critical heat transfer conditions. The
e-fficiencies of bladeless and bladed assemblies (with well
developed entry sockets) are equal. The vdlute,.-must be accurately

TITLE: The design j'f steam turbine stages, from the results of

TEXT: Two methods are in common use for designing the flow paths
of steata turbines. One L9 based on the use of generalized graphs
obtained from the tests on stages. With this method the
calculations are simple and reliable for the given type of blading,,
and various generalized graphs have been produced. The second
is based on the use of the energy loss factor and flow factors in
guide and runner blades, either derived from static tests or
calculated from the velocity triangle. This method is also
useful, particularly with new types of blade. A wealth of test
results is now being obtained on blades in straight bundles, giving

factors. An atlas of rational blade profiles has been built up
from these tests. Over a number of years, the Kafedra parovylch
i gazovykh turbin (Departmont of Steam and Gas Turbines) of MEI
has made studies of flow in turbine blades, using both flat
bundles and annular stationary models. Moreover, the blades
tested were run in experimental turbines to obtain
relationships between efficiency and velocity ratio, using both
superheated steam and air. The results so obtained can bridge
the gap between the losses determined in static tests and the
efficiency of actual stages running on steam. A number of loss
curves obtained with variOI;Ls kinds of stage with different kinds
Of test ZLre plotted and compared, and results are also given for aL
section of a turbine consisting of three stages. The results-
lead to the following conclusions. When the design of single-row
stages is based on the results of static blowing tests on flat
bundles of blades with an irregular velocity distribution and in
the presence of overlap, there is satisfactory agreement with
tests in experimental turbines in the region of low velocity V
ratio u/co. For optimum values of u/co the divergence between
Card 2/4
s/o96/62/000/003/001/008
The design of steam turbine ... E194/E455
test and calculated values is 1.5 to 3%. Generally, a
satisfactorily reliable result can be obtained by multiplying the
calculated efficiency by a correction factor of 0.98 to 0.97.
When calculating the stage efficiency from the loss factors given
in the atlas of blade profiles, the correction factor is 0.97 to
0.95 in the zone of optimum velocity ratio. For wheels with two
rows of blades the correction factor is 0-97 to 0.95 when the
calculations are made from tests carried out with allowance for
irregularity of velocity dintribution and for overlaps. When the
loss factors given in the atlas are used, the correction factor
should be 0.95 to 0.92. The least divergence between test and
calculated data is obtained in stages with long blades,urhich
indicates that end losses in the blades are not being sufficiently
allowed for. Correction factors for relating the result of tests
on stages in experimental turbines to calculated values from static,
blowing tests are valid for stages manufactured with welded
diaphragms. The results given in this article are only a first
step in relating the resultc of static tests to total losses -
determined in an experimental turbine. Further material must be

ABSTRACT: The.results of investigations carried out on four groups of turbine stages
with cylindrical and curved blades w~ h relative heights of 0.3-0.7 are presented..
It was found that the efficien _ - ~e turbine flow section between the inlet and
exit depends aa the conditions of flow transition from one stage to another. The
coefficient characterizing the utilization of the exit velocity was approximately
equal to 0.86~, it decreased sharply at relative velocities of 0.30-0.55. Recommen-
dations for obtaining economical relative velocities and blade cascades as well as
formulas for calculating the efficiency of individual 'turbine stages or blade cascadej
are SLven. Orig. art. has*. 7 figures, 16 formulas, and 1 table.

cling respectively to two possible P 8 of the
system. According to the experimental data two variants
of the values of the scattering length are possible.
A quailitative estimpte mde by the authors, based on the

=6.2 x 1o-3 cm, and al/2 = 0.8 x 1o-3 cm.

ABSTRACT: Yor the purpose of simplification the authors here investigate
even-even atomic nuclei. In the generalized model of the nucleus
the nucleons located outside the nuolous are described by means of
the one-partiole approximation, and the nucleons within the complete-
ly filled-up Shells (nucleus trunk) are noticeable only by their
collective properties. As collective coordinates the authors here
selected the three EULER angles as well as the variables 8 and r-,
which characterize the deviation of the nucleus from the spherical
shape. In adiabatic approximation inv%~stigation of the motion of the
outer nucleons in the field of a nucleus trunk with fixed shape can
be carried out., The energy of the interaction of the outer nucleons
with the nucleus,trunk (which are averaged over the state of
> - AScos of the nucleons) will depend upon the
motion
