ABSTRACT: A method is described for the approximate calculation
of the potential flow of an incompressible fluid in
axisymmetric curvilinear channels (the intakes of
centrifugal and axial compressors, diffusers at the
exhausts of axial compressors, etc.). The calculation
is based on a generalisation of the method of calculating
plane curvilinear channels (Ref 1). There is a comparison
between the calculated results and exact solutions. Good
agreement is obtained. There are 5 figures and 1 Soviet
reference.

ABSTRACT: Available methods of designing aerodynamic gratings at high subscilic
speeds are laborious and rather inaccurate. Simpler available
methods are not accurate enough close to the inlet and Lutlet ed-,ros
of the blade. This short article describes a simple approximate
method applicable to the design of gratings with small relative
blade pitch. The design procedure is as follows: the velocity
distribution over the profile is given for an incompressible liquid
and the corresponding velocity distribution with a gas is fourd.
Calculation of the potential flow of an incompressible liquid ma, be

TITLE: New Designs of Nozzle Blading for Supersonic Speeds
PERIODICAL. Teploenergetika,, 1959, Nr 11. pp 611-68 (USSR)
ABSTRACT: There is a need for high-efficiency nozzle blading for
supersonic speeds. Expanding nozzle blade profiles
developed in recent years are of high efficiency under
designed operating conditions,, but the efficiency falls
off rapidly when the conditions are cha.-riged. This will
be seen from curve 1 of Fig 1 which gives proflie
losses as function of Mach number for e-_,manding nozzles
type TS-2V,, At the design condition of Mach 1.6 the
losses are only 10%, but at Mach 1 they become 3.1%,
Normal nozzles with contracting channels work well only
at moderate supersonic speeds; see, for example, cijxve
4 in Fig 1, Methods of reducing t-he losses at
supersonic pressure-drops may be evolved from the
formulae for the chan-e of direction of flow -;in the skew
section of the nozzles. To this end sections before and
after the nozzle are considered, as shown in Fig 2.

condition are applied to these two sections and formula
(1) is derived for the relationship beTween the flow
conditions before and after the blading, From this
formula it is easy to determine the chari,-.e of direction
of flow in the skew sccbion of t-1he rioz.,.le -at -ouperson-ic
pressuro, drops, ari(l formula i.-- deriv(--,d.,
If an experimental relationship between th,:- velocity
ratio and pressure ratio is used, formula (2) is very
accurate. The accuracy is evident from FiE 3. where
experimental values are compared with values calculated
by formula (2). It has been shown that in nozzles with
expanding channels, for example those of the Moscow
Power Institute, the mean angle of discharge does not
depend much on the operatine-
_~ cond.Lt`ons., For this case
formula (2) may be used to cJetermine r-he relationship
between the velocity coefficient ai-Ld the pressure ratio,
as seen in Eq (3). The comDarisoa of" theoretical and
experimental results given in Fig 4 confirms the good

a:rreement. This a-reement was obt-ained without detailed

SOV/96-59-11-14/22
New Designs of Nozzle Blading for Supersonic Speeds
if the blading is made in such a way that the discharge
angle does not depend on the operating conditions, then
the losses must inevitably rise when the Mach number
is decreased. In this case the losses depend only on
the loss under design conditions of operation and on
the pressure ratio. This conclusion served as a
criterion of blade shape for supersonic pressure-drops.
The blade shapes should ensure variable discharge angle
on change of pressure-ratio and, therefore, the discharge
portion of the rear of the blade should be slightly
bent so as to increase the discharge area. Such blade
profiles differ from ordinary nozzle blades with
contracting channels only in the shape of the back face
of the blades. A group of new blade profiles that meet
this requirement are shown in Figs 5 and 6. Loss as a
function of Mach number for the new profile TS-2RV is
plotted in curves 2 and 3 in Fig 1. It will be seen
that for blading of similar efficiency at 1.5 the new
blading has much lower losses at lower Mach numbers.
Blade shape TS-lRV is recommended for nozzles where the
Mach number is 1.3 and blade shape TS-2RV when the Mach
Card 3/4 number is 1.5. Blades with back3 of the new shape should

New Designs of Nozzle Blading for Supersonic Speeds
be used for guide vlanes and working blading in stages
with long blades, and in particular for the last stages
of condensing turbines which operate at high super-
critical heat-drops. In the root section of such stages,
the velocity at the outlet from the guide vanes is, as
a rule, appreciably higher than the speed of sound. The
discharge angle from runner blades is also supersonic near
the periphery. As the last stages may operate under very
variable conditions, both guide vanes and riinzier blades
should have a curved back in the skevi section, There
are 6 figures, 2 tables, and 2 Soviet references.

lar manner to the previous case. Check computations of single sta-
,ge radial turbines and compressors demonstrate that the field of
meridional projections of speeds is irregular. 'When the disc and
ring are flat then the flow in the rotor can be considered as plane
parallel, thus reducing the problem to two dimensions. Liathemati-
cal equations -are quoted for the above. In order to assess speeds
near the inlet and outlet edges, it is necessary to elongate the
boundary lines of the stream inside the flow. Using equations ob-
tained to investigite the flow in channels between blades, impor-
tant deductions can be made. In particular, it must be noted that
the effect of Coriolis forces has a different effect on flows in
radial turbines (centripetal and centrifugal). The irregularity is
increased in the first instance, but improved in the case of cen-
trifugal motions. This should be taken into consideration when pro-
filing rotor blades. There are 5 figures and 4 Soviet-bloc refe-

ABSTRACT: Existing methods of assessing the losses that occur when
the angle of attack is not as designed are seldom
accurate for all types of blading. This brief article is
concerned with deriving improved formulae. The simple
case of thin straight flat blading is first considered,
neglecting compressibility and friction losses. The
diagram of Fig 3 is used in deriving the loss formula
when the angle of attack is not the same as the angle of
installation of the flat blading. The effect of the
discrepancy corresponds to a pressure drop, which may be
calculated by expression (2.1) and expression (2.2).
The latter coincides with Carnot's formula for the loss
Card of pressure when the section of a flow is suddenly in-
1/3 creased. The parameters of flow beyond the blading may
be calculated with allowance for compressibility, and

On the Determination of Losses in Turbine Blading when the Angle
of Attack is Incorrect
Eq (3.1) is derived. Similar methods may be used to
derive a formula for determining the losses in radial
blading with thin straight blades, giving expression
(4.1) for an incompressible fluid. Real turbine blades
are then considered; since the inlet edge is rounded,
the pressure loss is less than that given by Eq (2.2).
A correction factor is then introduced, as in expression
(5.1), and an appropriate value of this factor is
recommended for modern blade profiles. Expression (5.2)
is then derived for the relationship between the velocity
factor with the designed angle of inlet and with other
angles. The practical value of formulae (5.1) and (5.2)
depends on the validity of the blading correction factor
when the angle of attach and the types of profile are
changed. Some idea of the accuracy of formula (5.2),
assuming a constant correction factor, may be obtained
Carld from Fig 5, which compares experimental and calculated
2/3 data for three blades, two active and one reactive. The
satisfactory agreement between theory and calculations ir~

PERIODICAL: Metallovedeniye i termicheskaya obrabotka metallov,
1960, Nr 6, pp 2-7 (USSR)
ABSTRACT: Use of austenitic steels for cast components of turbines
and fittings operating at 600 and 6100C is inadvisable
due to their high cost, low thermal conductivity and
relatively poor technological properties. Therefore,
intensive research work is being carried out in various
countries to develop for this purpose pearlitic class
steels and steels with 11 to 13% chromium. Investigations
showed that if properly alloyed, pearlitic steels, and
particularly stainless chromium steels of the type
lKhl3, are suitable for operation in this temperature
range. The subject of the work described in this paper
was to determine the effectiveness of small additions
of horophilic elements (barium, calcium, cerium) on the
Card 1/4 properties of type 12KhllV2NMF steel. For the purpose

of comparison, one melt (7-104) was produced without
any additions. The chemical compositions of the
commercial heats used in the experiments are entered
in Table 1. Optimum heat treatment for this steel
proved to be as followst homogenization at 1090 + 100C;
normalization at 1050 + 10OC; tempering at 700 +-10*C
followed by cooling in the furnace. It was found that
in the case of continuous cooling from the range of the
austenitic state with speeds below 250OC/hr, there will
only be pearlitic transformation, whilst for larger
cooling speeds (250 to 3000OC/hr) pearlitic and
intermediate transformations take place. The plot,

this steel at 200C for a melt containing Al-Ba-Ce
alloying additions. The plot, Fig 2, shows the changes
in the impact strength of steel as a function of the

The relatively high structural stability of the material
is evident from the data on the changes of the chemical
composition of the residue produced by electrolytic
dissolution of the steel after various ageing regimes,
Table 2. Table 3 and Fig 3 show the results of long-run
strength tests (up to 2600 hours) in the temperature
range 600 to 6?OOC; the highest values were obtained for
material containing small additions of Al-Ba-Ca. Under
all test conditions fracture of the specimens occurred
along crystallites which were intensively deformed in
the neighbourhood of the fracture,as can be seen from
the microstructure of a specimen fractlired at 6100C
after having been stressed for 1011 hcurz~ with a stress
of 15 kg/mm . Fig 5 shows a plot of the creep limit
of steel at 6100C for steel containing --_-.-aly Ca additions
and for steel containing Al-Ba-Ca additions. The
following conclusions are arrived at-
1) Introduction into the steel of a small quantity of a

about a considerable improvement of the technological
properties of the tested steel, an increase in the impact
strength and ensures a higher degree of hardening in the
original state and a less intensive process of softening
during operation.
3) Introduction into steel of small quantities of Al-Ba-Ca
alloys leads to a reduction of the nonuniformity in the
properties along the cross-section and this appears to be
due to a greater uniformity of the structure, which leads
to a reduction of the size effect.

PERIODICAL3 Teploenergetika, 196o, Nr 7, pp 56-59 (USSR)
ABSTRACT- The design of the inlet pipe influences the efficiency
of a compressor in two ways. Firstly, losses in the
inlet pipe itself directly reduce the efficiency of the
compressor. More important,. the shape of the inlet pipe
influences the velocity distribution at inlet to the
runner. If the distribution becomes unsuitable it can
appreciably reduce the efficiency of the runner because
the angles of attack at the inlet edge differ from the
required values, Despite the practical importance of
this question, little experimental work has been done
upon it. Accordingly, the present work gives the results
of the first stage of an investigation on axially-
symmetrical inlet pipes. The tests were made not on a
Card 1/5 compressor but on a special rig, illustrated in Fig 1,

which allows the influence of the runner to be excluded.
However, the outline of the duct beyond the inlet pipe
is made the same as in a normal runner in order to
obtain the required boundary conditions. Tests were
taken on 8 types of inlet pipe, 5 being axial and
3 radial. Sketches of the inlet pipes are given in
Fig 2. Combined data on the losses are also plotted in
the graphs of Fig 2 in each case as functions of
Reynolds number. Since Mach numbers were small (less
than 0.35). the test results were worked out without
allowing for compressibility. All the inlet pipes,
except type OR-80-V, have very low loss factors because
of the low values of Reynolds number and in all cases
there is an appreciable reduction in the losses as the
Reynolds number increases. As was to be expected, the
axial inlet pipe with the least losses is that in which
the ratio of the inlet diameter to the outlet section is
greatest. The greatest losses were obtained with the
cylindrical inlet pipes. The tests show the advantages
of using short cowls over the runner inlet. Data on the

inlet pipe are also presented in Fig 2. The tests were
made for various values of average speed up to
110 metres/sec but because of the very slight influence
of the Reynolds number of the velocity distribution
Fig 2 gives mean curves. In all cases, except those of
the conical and cylindrical inlet tubes, there is marked
distortion of the velocity distribution. If the runner
were designed without allowing for this distortion, there
could be substantial reduction in efficiency, In the
axial inlet tubes, the velocity distribution depends on
the length of the cowl. It is most uniform with a cowl
of medium length and comparatively uniform with a
cylindrical inlet tube; but cylindrical tubes are not to
be recommended because of their inherently high losses.
Conical inlet tubes give a uniform velocity field and have
small losses. Thus they are the most suitable of the
axial inlet tubes, provided they can be accommodated in
the overall dimensions. Their main disadvantage is
their great length which can be overcome by making a
Card 3/5 profile of the kind illustrated in Fig 3. The results

TITLE: Contribution to the determination of velocities in an
axial turbo-machine, taking into account the
curvature of the streamlines in the axial cross-section
PERIODICAL: Teploenergetika, no.7, 1962, 50-53
TEXT: The problem has been solved in principle but the solution
is laborious, requiring 2 sets of approximations. In the first
approximation, the axial velocity components are determined from
the given tangential components, ignoring the curvature of the
streamlines in the axial cross-section. The c;ntinuity equations
then yield the streamlines and their curvature. From this
curvature, another approximation of the axial components is
obtained. NASA Report No-955, 1950, contains an approximate
formula for obtaining the second approximation streamlines fr-om
the first so that a third approximation is unnecessary, but the
computations remain laborious. H. Petermann ("Konstruktion",
1, 1956) has given an approximate solution dispensing with

successive approximations.but only-for a turbine stage with
50"j' reaction and a 'small 6riation*' of the axial velocities along
the blade length. A metfiod~eliminating successive approximations
but valid in the general casl' is given by the present authors.
The simplification has been achieved at the cost of two
assumptions: 1) the shift of the streamlines is assu med to follow
a sinusoidal law; this as:umption is equivalent to an absence of a-
shift at the root and the iiptof the blade and a maximum shift in
the middle; these conditions,prevail when the blade length is
constant; 2) the distortion of the axial velocity field in the
radial direction is sniall. These assumptions are formulated
mathematically and substituLed;'into the basic equations of flow i.n
a turbo-machine. The analysis gives a straightforward
computation sequence for the abtual velocity. The case of a
multi-stage compressor designe4 with equal stages is specially
considered. In this instance, the ratio of the blade length and
the width of the stage is the parameter which governs the
curvature of the streamlines. ; A numerical example is given
together with a graph in which-the axial. velocity components,

ABSTRACT: Results of experimental investigations with blade, diffuser-type
compressors are reported. The purpose of the investigation was to study the
effect of blade geometry on compressor efficiency. The flowing section of the
compressor is given in Fig. I on the 3nclosuros. The details of the blade geo-
metries (a total of 4 different types) are givon.in tabular form.: All except
N-1-9-18 blades were profiled. The compressor was operated at 25 .000 r.p.m:. and
T = 293K. Its efficiency was defined by

varying the number of blades. The optimum number was ZH m 25-28. The efficiency
of the compressor with N-0.5-4-18 type diffuser was less than the N-0*5-4-14
diffuser by 1.~%. Analysis of the ratio a,,./a., for these two profiled diffusers
