TITLE: EffDct of polarity on the physical properties of the
plasma stress of an arc generator
PERIODICAL! Zhurnal analiticheskoy khimii, v.18, no.1, 1963,' 20-23
TEAT: The same type of plasma arc generator was used as that
described by M.Margoshes and B.F.Scribner (Soectrochim Acta, 14,
no.2, 1959, 138) and Yu.K.Kravatakheli (Zavodskaya laboratoriya,
25, 1.960, 557). The d.c. source dissipating 2 kW in the arc was
employed. A spectrum was registered simultaneously on the
VICIFI-28 (ISP-28) and wcn-51 (ISP-51) spectrographs, using the
camera *34)-85 (UF-85). The diameter of the ccnatructing nozzle
was 1.8 mm. Industrial nitrogen was used for arc stabilizatiow.
The results of experimental investigations showed that the
polarity considerably influenced the performance of the arc and the
nature of the emission spectrum. With the nozzle working as an
anode, the jet was more stable and there was absence of side-
tracking channels. The current fluctuations of the discharge were
also quite negligible. However, with the nozzle acting as a

cathode, considerable jet instability and intensive side-trackings
were observed - also the brirlitness of the jet was increased.
The discharge current in the latter case dropped very rapidly,
while the arc voltage increased in such a way that the power in the
arc remained substantially constant. It was also found that the
intensity of the spectral lines derived from the nozzle material
was considerably stronger when the nozzle worked as a 'cathode.
The authors used brass and spectroscopically pure carbon as the
electrode materials. When the nozzle was made of brass and the
ro,' electrode of pure carbon, the intensity of the spectral lines
due to brass increased very markedly when the nozzle worked an a

spectrum contained a number of lines due to single-ionized copper,
and also emission bands of the molecular ion of N2 . The
temperature was also measured along the axis from the relative
intensities of tile Cu5106 and Ck,5153. The authors concluded their
work by studying the effect'of polarity on the broadening of

ABSTRACT: In view of the interest attaching to a simultaneous mea-
surement of both neutral-atom and charged-particle concentrations
in a plasma, the author investigates and demonstrates the feasi-
bility of an experimental determination of the inhomogeneity para-
meter of a source using any self-inverted pair of spectral lines, on
the basis of the theory of self inversion of spectral lines developed
by R. D. Cowan and G. H. Dieke (Rev. Mod. Phys. v. 20, 418, 1948).

:the overall half-line width was almost equal to the sum of the half-line width due

TITLE- Spectroscopic study of the properties of a S rsonic plasma Jet
SOURCE: Zhurnal prildadnoy mekhaniki i teknicheskoy. fiziki, no. 6, 1965, 47-52
TOPIC TAGS: plasma jet, plasma temperature, shock wave propagation, plasma charged
particle, spectroscopic analysis
ABSTRACT: The authors spectroqcopicany investigate the emission spectrum of a plasma jet
at wavelengths from 3800 to 5500 A. The variation of the temperature and concentration of the
charged particles along the jet was measured in relation to the polarity for a shock-wave jet
and a periodic structure jet. In the spectrum of the shock-wave jet the authors observed a
continuous spectrum at the base of the jet the intensity of which In the direction of flow notice-
ably diminishes and again increases jumplike in the shock wave and then abruptly falls off.
In the spectrum of the periodic-structure jet there Is an alternation of maxima and minima of
intensities of the continuous spectrum and of the intensity of the spectral lines corresponding
to compression and rarefaction points with a gradual weakening toward the end of the jet. The
temperature in the plasma jet was determined by the method of relative intensities with the,
use of two pairs of copper lines. The temperature was measured along the jet both for the

jet with a shock wave and for the jet with a periodic structure, at the base and in the rarefac-
tion and compression zones. The results of the measurements lay along a straight line, which
proves the feasibility of a Boltzmann distribution of the atoms with respect to the excited
levels. The concentration of charged particles in the periodic-structure jet was higher than
in the shock-wave jet. This was due to the higher temperatures and pressures in the jet.

TOPIC TAGS: discharge plasma, plasma beam, plasma jet, pulsed plasma generator, laser

ABSTRACT: A pulsed plasma generator, fired by a laser-generated vlasma is described
(see Fig. 1.) A 50-j laser pulse (,%,I msec, X = 1.06 ti) was focused by means of an
f:270 mm lens on a material embedded in brass-rod electrode 1, producing a plasma.
The plasma filled quartz-gla~s discharge chamber 3, causing discharge of artificial
line 5 (consisting of a 6-cell IM 3-100 condenser bank which generated a unipolar
Iv,300 psec current pulse) between ring 2 androd 1 brass electrodes located inside the
chamber. The resulting plasma jet consisted of plasmas of the eroded electrode and
chamber-wall materials. Under these conditions, the attendant pulsed discharge furthe
heated the laser-generated plasma, causing a sharp increase in the plasma generator
pressure (relative to the atmospheric pressure), and a quasistationary supersonic
plasma jet of a given chemical composition was emitted from the ring electrode.

The generation of the plasma jet was
observed by means of high-speed photo-
graphy and spectroscopically. The de-
pendence of tile plasma jet velocity on
the discharge voltage (at C = 600 )if)- is
shown in Table 1. Unlike in thecon-
ventionally-fired plasma generators
described by the authors elsewhere
(ZhPMTF, no. 3, 1965), where a gas is
fired to produce a plasma, the plasma
jet velocity in a laser-generated plasma
0-10 km/sec) is independent of the
electrode polarity. The plasma jet
spectra were studied by means of an
ISP-51 spectrograph with an f = 270 mm
camera in the 3800-6500 X range, with
a longitudinal focusing of the Jet on
the spectrograph slit. Qualitative
spectral analysis showed that the plasma.
jet consisted of vaporized electrode and
discharge-chamber (glass) materials.

4530.8 and 5105.5 A0. Only the temperature at the jet base could be measured ('-10,000K).

cross section nonuniformities of the jet. The charged particle concentration in a
laser-generated plasma (%5-1016 cm-3) is independent of the polarity of the ring
electrode. This indicates that a laser-fired pulsed plasma generator can be used
in spectral analysis as a high-temperature excitation source. This requires low-
voltage discharges at which the least pressure gradient occurs In tile discharge
chamber and the surrounding medium, reducing tht! jet broadening and increasing Its
uniformity. Orig. art. has: 2 tables and 3 figures. [YKI

ABSTMCT: The purpose of the investigation was to ascertain and compare the useful-

a method described earlier (ZhPs, v. 3, 201, -190) was useT-tpurpiculate the con-
stants of the quadratic Stark effect for more than 40 spectral lines of cesium. The
limiting charged-particle density that can be measured with the aid of each line was
determined. The dc arc (4 - 8 amp) was produced between carbon electrodes, with a
mixture of cesium salts with carbon pressed in one of the electrodes in different pro-
portions. The emission spectra of the cesium plasma were photographed with a DES-13
spectrograph. Eight spectral lines were chosen for the diagnostics, and their broaden
ing under different types of interactions was calculated and tabulated. The experi-
mental contours of these lines are derived and the concentrations of the charged

particles and neutral atoms are calculated for a dc arc plasma. Methods of improving
the accuracy of the results are discussed. The influence of various interactions on
the broadening of the spectral lines of cesium is evaluated (Van der Waals interactio:
Stark effect in inhomogeneous fields, resonant interaction, and Doppler broadening).
The accuracy with which the line width can be used to determine the concentration is
-30% for charged particles and -50% for neutral-atom concentrations. The results ob-
tained by different methods and with different lines were for most part in agreement.
Deviations are briefly discussed. The authors thank M. As Ellyashevic"or a dis-

action, supersonic flow
ABSTFV,CT: The authors (ZhTF, 35, 81 1965) have previously found that under certain
conditions supersonic plasma streams con be formed in a shock tube, that these streams,
have a complex structure due to wave processes, and that they can affect (and in parti-~
cular, can accelerate) the motioit of the luminous front. In the present paper they
report further experiments on plasma stronms in a shock tube,, The plasmas were pro-
duced by discharge of a capacitor between a conical electrode and an internal cylin-
drical electrode. The supersonic streams arose from expansion of the plasmas issuing
from the 4 cm diameter conical electrode into tho 6 cm diametor-glass drift tube. The
plasmas were observed by high speed cinematography and by streak photography, with
particular attention to behavior of the plasmas on reflection at the far end of the
tube. The velocity of the luminous front produced by a 2 kV dischargo increased from
about 6 km/sec, when it issued from the electrode, to 14 Irm/sec, after It had traveled

ABSTRACT: The plasmas discussed in the accompanying paper by L.I.Grechikhin and
L.Ya.Min'ko (ZhTF, 36, 1202, 1966 /-see Abstract AP60252457) were investigated spectrod
scopically in the range from 3800 'Eo 7000 A. Time integ-rated spectra were recorded
of the light from the discharge chamber, the central region of the drift tube, and thel
reflection zone. These spectra showed that the plasmas had the same composition in all.'
three regions and arose mainly from erosion of electrode and insulation materials in
the discharge chamber. Electron densities were derived from the spectra in three
different ways: from the depression at the Balmer series limit* from the linear Stark
broadening of HP, and from the quadratic Stark broadening of CII 4267 1~; Wlien two of
the techniques were simultaneously applicable they gave concordant results. The
charged particle densities were slightly higher in the reflection zone than in the

ABSTRACT: Analytical results are given of wind-tunnel tests carried out
at the Leningrad University wind tunnel by the Tsentral'nyy
nauchno-issledovatel'skiy institut morskogo flota (Central
Scientific Research Institute of the Maritime Fleet) of a series
of propeller profiles, the purpose of the tests being to refine
the logarithmic diagram which V.M. Lavrent'yev had compiled
in 1945-46 by analyzing and averaging various experimental
propeller data available at that time. Selected for these
special tests was a base series consisting of five systematic
propeller profiles with thickness ratios ranging from 2076 to
516. To clarify the influence of the profile camber, tests were
made of four propeller profiles with various amounts of cam-

thickness ratios of 10 and 7.5 percent respectively). The investigation in-
cluded a determination of the chordwise and normal-force coefficients and
the section pitching-moment coefficient of the profiles in a curved-flow
test and a determination of the pressure distribution which was done by
means of pressure orifices at 23-25 points on each of the nine models over
an angle-of-attack range up to the stall. Ultimately the Lavrent'yev dia-
gram is derived, establishing the connection between the elements of a
propeller blade and hydrodynamic characteristics of the propeller.

ABSTRACT: A method is presented for calculating the lift and power required for
raising -rhicles with air chambers and continuous annular nozzles. Both types of
vehiclesl-~xe studied. Vehicles with air chambers are structurally very simple
since they do not require air ducts. Air is forced under the dome of the vehicle
and escapes a-long its periphery. Lift is produced by the pressure increase in the
lower part of the dome. Expressions are given for calculating the rate of airflow,
lift, power required for sustaining the vehicle on the air cushion and specific
power. All these parameters are determined for circular vehicles. The basic prin-
ciples for operation of vehicles with curtain type air cushions are also discussed.
The use of this type of vehicle seems more feasible for marine operations-than

vehicles with air chambers. The region of increased pressure is much more limited
in vehicles with annular air curtains -than for those using air chambers. The air
curtain is formed by the air stream from the nozzle unit. A figure is given show-
in.- the principle of operation for this type of device. An air stream leaving the
nozzle at a given angle with respect to the vertical is deflected and disperses
along the horizontal surface. The equation of Euler is used for determining air
stream variation for every possible cross section in the case of an ideal incom-
pressible liquid. F_xpressions are given for calculating the lift of this type of
vehicle and the power required for holding it at a gived distance from the surface.
EApressions are also given for calculating the resistance encountered by vehicles
operarting on air cushions during motion. The results of the study show that the
specific power for boats operating on air cushions increases shaxply with increased
height above the operating surface. This is caused by increased air consumption
and results in additional pressure requirement on the fan. The nozzle type air
cushion is much more efficient than the air chamber type since it does not lose as
much power on lift. The results also show that an optimum angle of nozzle declina-
tion exists for each nozzle diameter and lift height with respect to given vehicle
dimensions. A graph iz given for determining this angle. Though theoretically a
circular air cushion is most efficient, experience shows that this causes power
losses expended on motion of the boat or vehicle. In designing boats operating on
air cushions it is necessary to consider these conditions and to adopt oval de-
signs. Optimum air cushion pressures increase with vehicle velocity. The proposed

ABSTRACT: The author considers a lightly loaded isolated screw propeller operating in
an infinite flow of ideal incompressible liquid assuming that the angles of attack
for the elements of the blade are vanishingly small so that the associated circulation
at each element of the blade is variable. The vortex system of an m-bladed propeller
is considered where the circulation is constant with respect to radius and varies in
time. The expressions derived are used for determining the effect which the free vor-
tex system has on the magnitude of the induced velocities during the reversal period
from the moment when the load is removed from the main engine until maximum-negative
torque is reached in the hydraulic turbine. It is found that the vortex system
shortens this period as compared with steady~-state motion. However, since practical

Abstract The post-warand present trends.in development of construction and
road building machinery are summerized. Some 600 types of construction
and road buidling equipment were produced in post-war years and the
production of heavy road-building equipment in 1954, increased 10.5
times over 1946. The follmiing equipment is described: single and
multi-bucket excavators,, scrappers., graders, rollers., derrick cranes,,.
loading cranes, tar and cement spreaders, cement mixerso and the tile
and brick presses. Illustrations.

TITLE: Working Day of an Engineer (Rabochly den, inzhenera-)
PERIODICAL: Vestnik vozdushnogo flota, 1958, Nr 3, pp 62-65 (USSR)
ABSTRACT: The article describes the working day of an engineer in
an air force unit. At the beginning of his article the
author states that one of the very difficult tasks of
technical personnel is to prepare the aircraft for flights
in cases where the same aircraft is flown by several pilots
in succession on a flying day. The aircraft equipment can
be checked only during the refueling time between the
flights. With the establishment of a seven-hour working
day, the personnel alsohave some difficulties In coping
with the amount of work that has to be performed. Among
other things, the author mentions that at the present time
aircraft equipment is checked with the aid of special mea-
suring instruments. Of interest is the fact that the repre-
sentatives of factories frequently visit the unit engineer
and discuss various problems connected with aircraft equipment

ABSTRACT: In general., defects in the equipment of supersonic fighters in the
author's unit were usually caused by cable breaks in electric circuits, break-
downs or short circuiting, changed parameters in condensers or resistances,
deranged adjustment or reguIation in various systems, incorrect operation of
feed sources, and leaky piping in air or oxygen systems. The following ni
"most interestingn defIects which occurred in that unit are discimsed in detail
in the article. (1) The dynamic-pressure piping in an airspeed inUcator leaked.
(2) a tube supplying fuel to the engine broke. (3) screws securing cables to a
unit (the latter was attached to the engine) were turning off under vibration;
impaired operation of the engine resulted. This defect was remedied by "put-
ting the screws on the paint", and by periodic checking. (4) a moisture-exclud-
ing lid, used when the aircraft was on the ground, failed to protect satisfact-
orily and as a result, a push button, controllng flaps [shchitki-zakrylkil,
became stuck by icing. This was remedied by drilling drain holes for mDisture.
(5) 7he filter In tJm cabin air-temperature regulator became dust clogged after

operating for 80-90 hre.; it resulted in a defectivie supply of air to the cabin
(in winter), with a possibility of mechanical. ela ge. Cleaning the filter screen,
by blowing compressed air through it was recommended. (6) The installatim of
the "barospeedograph" in the aircraft was a pi-iblem for aom time; finally, a
satisfaetory place for this instrwoent was found inside the 8urface, beside
the gun- (7) An improved cc%qzss is now being installed in fighters. 7he trans-
ition from the old to the new model caused certain difficulties which "rational-
izers" removed by combining the new model with some parts of the old one; some
changes an the instrawat I were alao m~. This was done only in a single
pair of aircraft. A similar alteration was carried out in -the TL-1 ground trainer.
The use of the ec"ss presents sow difficulties due to dissinilar installation
of some units making up the complete compass system in differeirb modifications
of the same aircraft. (8) The booster trunsforzvr is the most vulnerable part
of that compass. The compass gets out of senrice- when a b:reakdowr- occurrs in
the transformer. (9) The readings of the exhamst Sas thermometer drop after
the engine has run for 70 to 80 hours because the insulation covering the thermo-
couple then becomes abiarred and turns into Powder under action of beat. With a
cold engine, it is sometimes impossible to determine by means of a tester which
thermocouple went out of service. There are 3 photographs and 1 diagram.
