Title : Studying operations of adjustable-blade hydraulic turbines
with closed draft tube gate
Periodical: Gidr. stroi., no-3, .30-33, 1955
Abstract This report is a mathematical analysis of tests made with
various hydraulic turbines of the adjustable blade type
equipped with a gate at the outlet of the draft tube.
Results showed that a Past closing of the gate produces
the raising of the rotor, -the pressure in the draft tube
exceeds the pressure In the spiral chamber, and the rpm
in turbines should be determined considering a number
of additional factors.

TITLE: Operation of Kaplan Hydroturbines With Closed High-Speed Shutter in
Suction Pipe (Rabota povorotnolopastnykh gidroturbin pri zakrytii
bystrodeyovuyushchego zatvora v otsasyvayushchey trube)

Engineering Institute), 1956;jpp 93-110

ABSTRACT: High-speed shutters in suction pipes are used to prevent runaway of a
hydrogenerator set. However, actual experience with these shutters revealed
a possibility of unfavorable phenomena such as a considerable pressure rise in
the suction pipe and lifting of the turbine rotor caused by the reversal of the
axial force on it. In a laboratory of the Chair of Utilization of Hydropower,
MISI imeni Kuybyshev, studies of the,phen:omena occurring when the shutters
are closed were conductedjon a model turbine with a 180-mm rotor diameter);
an application of a graphical method of calculating. turbine operation was tried.
The above studies consisted of two stages: (1) operation of the turbine-

of Kaplan- Hydr oturbinem With,Closed-High-Speed Shutter-in.Suction Pipe,
generator'set under st'eady-state conditions at various positions- of the shutter;
(2) dynamic phenomena accompanying the closing of the shutter, with continu-
oua oscillographic recording of the torque, axial force, rpmo pressure in the
auction pipe, and shutter travel. In static tests, torque and axial force were
determined as functions of rpms at various positions of the shutter. The re-
sults of these tests were used for graphical calculation of conditions produced
by the closure of the *shutter. A juxtaposition was made between the results of
the above graphical calculation and the results of later dynamic tests conducted
on the same model and with the same initial parameters. The graphical
method is based on the application of finite differences by means of breaking up
of the process into time elements. In the course of calculations, the head is
considered constant and the time charactieriatic of closing the shutter known.
An example of calculations is given for the turbine of 9-meter diameter, 57-Mw
capacity with 18-meter head. In those cases where experimental data for vari-
ous positions of the shutter are unavailable, use of approximate character stics
is recommended. Torque characteristics for a higher speed range are assumed
linear; the flow through the opening of the gate is calculated from a formula;

Operation of Kaplan Hydroturbines With -Closed High-Speed Shutter in Suction Pipe
head differential at the gate is taken into account. Am example of calculations
for such a case is also presented. A comparison is also given of the above
findings (torqud, axial force, drop, maximum rpms) with a graphic calculation
according to the authors' recommendations. The discrepancy with the results
of graphic calculation is insignificant. A comparison of the results of dynamic
tests with those of graphic calculation reveals a fairly good agreement between
them, except at the point of extrame values of torque and axial force (deviation
about 50%). which could have been caused by the peculiarities of the experimen-
tal installation. The above method of calculation will be verified during the
coming tests at an actual hydroelectric station. Bibliography: Three items.

PERIODICAL: Avtomobillnaya promyshlennost', 1958, Nr 7, PP 13-15 (USSR)
ABSTRACT: The angle of camber and tow-in of the front wheels of auto-
mobiles iB an important factor on the wear of the tires and
thus to the car's road resistance. Relevant calculations were
confirmed by tests carried out in the Moscow Automechanical
Institute by the authors. The results of tests on 5.00-16 tires
put on a "Moskvich" car of model 400 - 420 at normal 1.8 kg/
square .-.m tire pressure, a vertical load of 500 kg and 10 to
30 km/h motion speed, are shown on graph 5 and demonstrate
that theoretical and experimental data must be obtained for
various types of tires, to find the best possible angle of
camber and tow-in for front wheels.
