ABSTRACT:
ornithodoros lahorenoin ticks were Infected with the
tick-borne typ1jun patl-- gen Darmacantroxenue aibiriaua
by feeding on infected guinea pigs and by introducing the
ric'kettaia directly into the body cavity. The ticks in-
fected by feeding retained the pathogen for 420 days, and
the parenterally infected ticks for 300 days (to the end
of the observation period). The infected tick* retained
the rickettsia through the subsequent stages of metamor-
and transmitped.,,t-tem by ovum to their progeny.

Parentaily-7infected ticks transmitted the rickettsia to
uninfected laboratory hosts (guinea pigs and rabbits)
1by feeding. The rickettsia were seen in the amebocytea
of tick hemolymph by the 4th to 10th day after parenteral
infection. Dermaoantroxenue sibirious can be transmitted
'idirectly from infected to uninfected ticks by parenteral

TXTLZ The Automodellike Motion of a Gas on the occasion of a Vehement
Peripheral Explosion.

Like the explosion in the symmetry center of a gas at rest, which was investi-
gated by L.I.SEDOV (Prikl.matem.i meoh.,10, faso.2 (1946)), also the auto-
modellike motion on the occasion of a vs_hs~ent peripheral explosion can be in-
vestigated. Such a peripheral explosion causes a strong shock wave to move
towards the symmetry center of the resting gas (density Q,). The pressure P1
of the resting gas is assumed to be negligibly low compared to the pressure
P, behind the shock ways. If E in the characteristic energy of the explosion,
t 9 only dimensionless variable combination of the parameters is
A _ (Z/Q,)(t2/rl+lr). Here r denotes the linear coordinate, t - time, and it
holds that Ir - 1,2 and 3 for a plane, cylindrical and spherical flow respec-
tively. On this occasion the amount of energy enclosed between the surfaces
const in constant. To the position r2 of the shock wave there corresponds
2 2 + 1,'
a certain constant value of the parameter: A 2 - (EAI)t /r2 Accordingly,
the propagation velocity o of the shook wave is:
C IL V A /(2 +V) rV12 . (2/(2 + )r)) r

towards the symmetry center of the resting gas (c > 0) corresponds to a domain
with the modification of t from - w to 0. When approaching the center, the
velocity of the shook wave increases sharply, and accordingly also the pressure
P2, the velocity Y21 and the gas temperature T2 behind the front of the shook
wave will grow too: P2" (2/(K +1 ) ) Q, c21 v 2- (2/(,V +1 ))c; "e'
it is true that T2- 1/r 2v . - The flow of the gas behind the shock wave is
described by the aforementioned solution by L.I.SEDOV. The integral curve in
the V,z plane is given (v - rV/t; Q - qjRj p - z - Xp/R). To the here inveati-
gated current there corre 8ponds the portion of the integral curve between
(V 2,z2 ) and ((2/(2+ V')),O). The same formulas are used in this case for compu-
tation as in the case of the aforementioned work by SEDOT. - Three diagrams
illustrate the results of the computation of the velocity-, density-, pressure-,
and temperature profiles for the plane, cylindrical, and spherical case at
k . 1,4. The domain of the automodellike motion is between the shock wave
and an exterior boundary with the radius rK' On the exterior boundary r. the
flow velocity of the gas and the motion velocity of the boundary are identical.
Such a flow is @.g. obtained on the occasion of the contraction of a hollow
piston in the direction towards the center. The here investigated cylindrical
flow in suited for the determination of the steady flow round a correspond-
ingly thin rotational body at high supersonic velocities.

ABSTRACT: At high supersonic speeds the shock drag coefficient is
entirely determined by the nose portion of the body.
Reference is made to previous work wherein the levelling
out of the shock drag coefficient at high supersonic speeds
was recognised. based on the similarity laws previously
discovered, simple formulae are derived (equations 8 and 9)
for the pressure distribution over the suriace of the body
in terms of the angle of rotation of the flow in "~Ihe shock
wave. In Figs.2, 3 and 4 pressure distributions so derived
are compared with values computed by the method of
characteristics for a bi-convex profile and with the test
results in the nose portion of a solid of revolution.
These results show that at high supersonic speeds the
C&rl 1/2 relative pressure over the profile is, in the first approx-
imation, proportional to the square of the sine of the

speeds. ~Cont.)
angle of slope of the profile. This property makes it
possible to obtain analytical expressions for the aero-
dynamic coefficients. Several variational problems are
considered. In plane flow, the shape of a body with the
minimum frontal drag for a given length is found to be a
wedge. The shape of a profile with a minimum shock drag
for a given moment of resistance to bending is expressed
in eq.(15). In axially symmetrical flow, the minimum drag
shape is given by eq.(17). Its drag is 0.844 times the
dra of a cone. When friction is taken into account,
eq.&O) gives the optimum shape. The flow about a body
whose profile is described by'the 0.?5 power of the chordal
coordinate is examined. Such a body has a shock drag 2?%
lower than the equivalent cone.
There are ? graphs and 15 references, 8 of which are Slavic.

ABSURACT: A non-linear theory of a "wing-body" interference in a
supersonic flight is described. A conical shape of a fuse-
lage with a triangular wing (Fig.1, a), a semi-conical fuse-
lage with a triangular wing (Fig.1, b) and a split-type
fuselage with a similar wing (Fig.1y) are considered. The
calculations are based on Refs-1-13 with the following amend-
ments: the geometric relationship of the conical fuselage
(angle 2w) is shown in Fig.l,a where:

ABSTRACT: The electrodynamic equations of maKqetohYdroq2Mamicj and
the equation for the current density j are simplified by
the assumption that the velocity and current density
component v and J0 are zero, (a cylindrical
coordinat: syspem, r ,el x is used). For meridianal flow
of an incompressible conducting fluid at constant velocity
vX = v0, if r =H0, and a further simplification can be made.
A solution for H 0 is sought in separable form as XWR(r).
To this solution a linear term in the radius is added to
satisfy the equations of motion. Boundary conditions are
derived by assuming that the cylinder which bounds the
Card 1/3 fluid is non-conducting. Similarly to the known exact

solution of the flow of a viscous incompressible fluid
it is shown that in the case of the meridianal flow of
an incompressible conducting fluid the equations of
magnetohydrodynamics permit of a class of t'automodel"
solutions (dimensional analysis is invoked). The
velocity and field components and the pressure are
expressed in terms of the non-dimensional parameter
I = x/r and the functions of this parameter which occur
are determined by the solution of four ordinary differen-
tial equations. These equations are solved by introducing
a function related to the stream function. The direction
of the current along rays passing through the origin is a
characteristic of the flows under discussion. Two
examples are discussed. One is a conical charge in an
unbounded medium. The other is a charge in a conical
channel with non-conducting walls. Finally the similarity

Experimental investigation of the interaction between

TEXT: In many types of supersonic flow, an interaction between
compression shocks and the boundary layer takes place. Typical
cases of flow with and without separation of the boundary layer
are illustrated in principle including flow past a re-entrant
angle, the reflection of an oblique shock from a wall, outflow
from a nozzle or a diffusor and flow past an aerafoil. Separation
depends upon the intensity of the compression shock and the
initial velocity profile in the boundary layer. In the case of a
turbulent boundary layer over a flat plate, the velocity profile
is independent of the Reynolds number, at least between 0.78 and
50.0 millions. Downstream of a compression shock, substantial
transverse pressure gradients can exist at the outer limit of the
Card 1/6

boundary layer. However., very near the wa'A. where the separation
begins, it is always possible to select a -igion in which the
transverse pressure gradients are substant Ily smaller than the
longitudinal pressure gradients. The sepa t:.on point is defined
by a longitudinal pressure gradient obeyinj a relationship which
contains also the velocity and static pres-si-e in the undisturbed
flow, the thickness of the boundary layer a the point of separa-
tion, the ratio of specific heats and an e.N - rimental const-.nt.
Experiments show that in the interaction of ompression shocks and
the boundary layer, the rLse of pressure al~i K the wall proceeds
over a certain length. It is shown that th ratio of this length
to the thickness of the boundary layer at ti point of separation
can only depend on the shape of the initial elocity profile in
the boundary layer of the plate and thus is idependent of the
Reynolds number. Therefore, the separation f a turbulent boundary
layer from a flat plate is mainly dependent i the pressure ratio
across the compression shock. This critAca ,regaure ratio depends
mainly on the Ma--h numter of the flow and h been thoroughly

proved to be in conflict with existing individual measurements.
The present paper is devoted to an experimental study of the
critical pressure ratio in the Mach number range between 1.0 and
1.8 (local value upstream of any compression shock). Experiments
with a flat plate were carried out in an installation with the
rectangular working portion of 90 x 120 mm cross-section, in
which a flat plate of 320 mm length and 90 mm width was set up.
An additional wedge was placed above the plate to produce a
system of compression shocks. Adjustment of the setting angle of
the wedge controlled the intensity of the system of oblique
shocks. The static pressure distribution was measured at the
plate surface by a series of holes. The two side walls of the
rectangular working section were made of a flat mirror and of
optical glass, respectively. The optical spectra of the flow
were photographed and examples are reproduced. To detect the
boundary layer, a T-shaped microprobe of 0.5 mm diameter and 5 Mm
length was placed on the plate surface. The holes in the probe
were 0.25 mm above the plate face. The pressure drop measured by
the probe indicates the flow direction near the plate. The
separation point occurs where the pressure drop is zero. The
Card 3/6

results of the measurements are plotted in the form of the
critical pressure ratio against the Mach number. Measurements
were also carried out with axially symmetrical nozzles operating
at pressure drops different from the design value. A conical
compression shock forms at the opening of the nozzle. Since the
pressure gradient near the opening is small, conditions are
similar to those over a flat plate. When the shock reaches a high
intensity, a flow separation can take place. A study was made of
the effect of the Reynolds number by varying the static pressure
behind the nozzle. The effect was negligible. The existence of a
turbulent boundary layer was proved by measurement of the
velocity profile. Throughout most of the examined range of Mach
numbers the critical pressure ratio varied between 1.6 and 1.75.
Below a Mach number ef 1.25 even a straight compression shock has
a pressure ratic under 1.6 so that the flow always remains without
separation. These results,obtained for the region of interaction
between the shock wave and the boundary layer where the pressure
gradient is zero, can be used in the analysis )f supersonic flows
with small pressure gradients such an the flov in nozzles, the
flow past profiles, the flow in an oblique no2.,.le opening and

E191/E581
others. Positive pressure gradients promote (andnegative gradients
retard) the beginning of separation. In nozzle flow, the results
obtained in the present paper yield that pressure drop through the
nozzle beyond which the flow remains without separation. It in
pointed out that, at a pressure drop below the design value, flow
separation increases the thrust of a reaction nozzle so that separa-
tion can become a favourable factor. The conditions of separation
in flow past an aerofoil section are discussed. The largest
incidence without separation is reached by a section with a flat
upper surface.. Among the symmetrical profiles which have a lower
wave drag than non-symmetrical profiles., the rhomboid reaches the
largest incidences without separation. Segmental profiles of 9%
thickness have no range of incidences without separation. The flow
in the oblique cross-sertion of a cascade of blades (for example,
the outlet annulus in a turbine stator) is examined. Featuresof the
blade profiles can be chosen, which ensure flow without separation
at supersonic outlet velocities. The main parameter is the angle
between the directicn of the outer velocity and the tangent to the
back of the profile at the outlet cross-section. This angle should
be as near zero as possible to ensure lack of separation, a narrow

motion for a body of variable mass m for N = const will be
considered. The equations of motion and energy have the form:

An expression is dorived relating the power source weight ON to the flight trajec-
tory characteristics.' In Part Two the motion of a power-limited vehicle is
idiscussed for the case of engine operation time less than the vehicle flight dura-
'!tion. The variational problem is considered under variable thrust power flow rate i
;and thrust vector conditions with the optimum combination of power-limited and ex-
1haust velocity-limited engines. It is shown that this combination yields an advan-
itage in total payload if each type of engine has the same payload before combina-
f'tion. Part Four deals with reliability in engine performance for missions of long
duration. The optimization criterion assumed here is the condition of a minimum
:in the sum of average necessary and reserve fuel weights plus the dead weight of
':t-he engine. An example is given where it is shown that in a round trip mission the,
,departure leg takes place faster than the retUrn leg of the trip, shifting the
!given eagine-time break to the beginning of the trajectory. The optimization
studles are extended to include weights in addition to the previously considered
weights'of working substance, power source, and payload. Finally, mid-cour3e
correction possibilities are studied, including corrections in velocity and posi-

flight with low thrust. Included in this problem are selection of the optimum ratios
between the weight components of the spacecraft and optimum control of the thrust
system as well as determination of the' optimum trajectories of the flight in the aggre-
gate. A relationship is established between the weight characteristics and parameters
of the engine system and the possibilities for thrust control are discussed. Optimi-

the problem of optimization for an ideal system resolves into two independent prob-

weight of the working material and 2. finding the optimum trajectories and programs
for the rocket acceleration vector. The literature covering the numerical solution
of these problems is briefly reviewed. Orig. art. has: 13 figures, 34 formulas.
