ABSTRACT: A conventional system of coordinates is usually established
at the beginning of the designing and construction of large
industrial constructions, hydroelectric power plants in part-
icular. The author states that it is necessary to choose
such a system in which the axis X coincides with marking
axis of the line of direction. The intersection of the
axis Y and the beginning of coordinates must be placed on
any picket of the marking axis or at the intersection of the
axis of the sluice, if there is one. This system will great-
ly simplify all following.designing operations for all kinds
of work. All the main elements of construction will then
have only positive X meanings of the coordinates. There is

ABSTRACT: This is a discussion of.proposals to introduce cer-
tain changes intothe geodetic system used in the
construction of,hydro-eleetric Bites , which is
always preceded by complex engineering research
work to determine the suitability of the terrain,
An important part of the team are the surveyors,
who on the :Instructions of the Main MVD Board for
Geodesy and Cartography usually work at scales of
1:5,000 or.1:2,000. The complicated nature of the
construction of hydro-electric sites is rendered
even more so by the presence of underground insta-
llations, which call for a high degree of accuracy
on the pc-rt of the surveyors. However, in many ca-
ses experipace has shown that the accuracy was in-
Card 1/3 sufficient for the demands of the constructors of

SOV/98-59-7-12/22
Geodetic and Surveying Work at Hydro-Blectric Sites
the pr ojeats~, and thus, at the commencement of buil-
ding operations the surveyors have now to make a
more detailed, accurate plan of the scheme (trian-
gulation of Classes II and III of city networks,
and sometimes Class 1, as in the case of the Dnepro-
project) This work requires additional funds
(2001 300,000 ;ubles) and takes 3-5 months, since
it has to be carried out by the surveying team,
which is understaffed during the organizational pe-
riod. ItAs simularly unwise to carry out under-
ground ope7~ations without a highly accurate geodetic
repor-6 first being obtained. It would therefore
seem expedient to have this work carried out, for
cheapness' sake, by the planning and research team
to satisfy the requirements of the constructors.
For large GES projects (such as the Bratsk GES) and
medium-sized ones where underground installations
are planned, the official triangulation of city net-
works Class II is recommended, while Class III is
more suitable for-average-sized plants with no under-
.Card 2/3 ground installations. Due to this method a loss of

SOV/98-59-7-12/22
Geodetic and Surveying Work at Hydro-Blectric Sites
up to 30% of the geod6tic signs is possible this
being inevitable in view of the frequent changes
that take place in the plans of GES projects. This
will somewhat raise the cost of -'--he initial research
u
(which should 'be taken into account) but since it
excludes any chance of repetition it will eventually
cover any additional initial costs. It also obvia-
tes the need for a large staff of surveyors, etc.,
during the initial period. These proposals are sta-
ted to be only valid for GES proj ats which are '-Ake-
ly to be realized in the near future.

TEXT: The development and preliminary tests are-describod
concerned with an improved design of an air-cooled gas turbine
rotor blade. The design is distinguished by the details of
joining a hollow shell constituting the external surface of the
blade to the load-carrying core, which is integral 'with the blade
.root and is itself hollow to permit the passage of air. It 'is an
essential feature of the new design that a clev~rance is maintained
all round the core between it and the sholi throughoixt the working
length of the blade. The shell is attached to the core against
the centrifugal force by a butt strap at the tip, which is welded
to the core or formed in it by stamping after the fitting o" the
shell. The cooling air is'fed through holes in the root into the
caviti of the core, from which it emerges through holes in the
leading edge of the core towards the inside of the leading edge

of the shell. Flowing in the clearance between the core and the
shell tangentially along the profile, the air is discharged into
thb main stream through apertures near the trailing edge of the
shell. In 1949, tests were carried out at the Laboratoriya
turbomashin (Turbo-Machine Laboratory) of the KAI with a similar
design of air-cooled blades, in which, however, contact was
maintained between -the shell and the embossed core along various
lines. The core took part in'the heat exchange between the shell
and the air. Effective cooling of the shell could-be obtained
bUt only at the expense of a higher core te;;iperature and a non-
uniform temperature distribution. In the new design, the lowest
core temperature is achieved and a smooth temperature distribution
prevents warping and distortions. The manufacture of the new
type of blade is easier. Moreover, the shel 1 continuously
operates under compressive stresses. Even the small gain in high-
temperature strength obtained under compressive load can greatly
add to the safety of the blade.assembly. Practical tests were
carried out to determine the structural stability of profiled
shells in compression'. Blade lengths between 50 and 200 nim and
blade chords between-30 and 40 mm were included in over 200 tests

of Shells, 0.4 - 0.5 mm thick made of several heat-rosisting,and
other ferrous materials.' It was.shoim that loss of stability
did not constitute a separate strength criterion compared with
high-temperature strength. Effective cooling of the shell-by
over 2000C could be obtained compared with the uncooled blade and
the core could be'c*ooled down to 200% (at a gas temperat ure of
800*C). There are 8 figures.

ABSTRACT: The article is in two parts: the first -deals with the derivation of the equations,
the second with an approximate method for' their solution. The coordinate axes are
Selected M* accordance with the calculation diagram (Figure 1 of the Enclosure): axis z is
in the radial direction; x coincides with the external contour of the profile. The following
fundamental differential equations are derived in the first part of the article: 1) A differ-
ential equation for the temperature state of the envelope, disregarding radiation heat and
temperature change throughout the thickness of thwenvelope; 2) An equation describing the
temperature state of the shaft core; 3 & 4) Equations describing the heating of the air in
the,first and second contours. These equations represent a olosod systom, through the

solution of which il,* is possible to deter .mine the functions of practical interest; namely, the
temperature of the ;envelope, the temperature of the shaft core (Figure 2, of the Enclosure)
'and the temperatuxies of the. air' in the first and second pontours (Figures a and 4 of the
Eiiclosuire)_. -All Ormsof the equations are complex ~aifablo fimetiofis; depending 6n 'one

no e at
in a general form is impossible through conventional mathematical techniques; however,
In the majority of cases of practical importance thdro are sufficient particular solutions
(for example, by disregarding the thermoc' Ionductance of the envelope). For more accurate
computations, when there is a need to determine the complete temperature fields of the
blade, the authors propose the following method: fiid a particular solution of th -a equations, x
on the premise that the functions change in one direction only; then find the solution for the
change of functions in the other direction. , In the present article, the authors solved the
equations for the following particular case: 1) Viermoconductivity along the profile is in-
finitely great; that is, thermoresistance is disregarded; 2) Within the sections, into which
the blade is brokeh down, the heat transfer factors from the gas and air in the second
contour, as well a's the temperatures of the gas, envelope, and air in that contour, are
considered constant; 3) A case is considered in which the air is fed (to the second contour)

through a series of apertures (this being the most convenient): 4) The effect of radiant
heat transfer Is disregarded; 6) The absence of air reflow between adjacent sections is
assumed. Th order to verify the methods developpd, calculations were made of several
test conditions of experimental blades. The results of thooomparlson indicated satis-
factory agreement of the theoretical. and cxperimental data. Orig. art. has- 6 figuros.
