PERIODICAL Dokl.Akad.Nauk,111, favc-5, 969-971 (1956) Issued: I / i~7_ 57 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).

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 24-6-13/24 Some pro erties of the flow around bodies at high supersonic 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. SUBMITTED: April 16, 1956. AVAILABLE: Card 2/2 !G. L.

Equalization of the Parameters of the Rotational Flow of a Viscous Fluidi PERIODICAL: Izvestiya Akademii nauk SSSR, Otdeleniye teklinicheskikh nauk, Mekhanika i mashinostroyeniye, 1960, Nr 1, pp 41-46 (USSR) I 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 69295 S/179/60/000/01/006/034 E031/E535 The Axisymmetric Meridianal Flow of a Conducting Fluid. Equalization of the Parameters of the Rotational Flow of a Viscous Fluid 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 of the above problem with that of the axisymmetric flow of Card 2/3 a viscous fluid moving with constant velocity inside a 69295 S/179/60/000/01/006/034 E031/E535 The Axisymmetric Meridianal Flow of a Conducting Fluid.

(Moscow) Experimental investigation of the interaction between compression shocks and the boundary layer in the range of Mach numbers between 1.0 and 1.8 PERIODICAL: Izvestiya Akademii nauk SSSR, Otdeleniye tekhnicheskikh nauk. Energetika i avtomatika, 1961, No.4, pp-20-31 + 2 plates 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 2764? Experimental A`nNestigation of ... S/024/61/000/004/005/025 E191/F581 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 examined by previous i-vestigators for the ge of Mach numbers above 2.0. Extrapole4ion into a range of i ller Mach numbers Card 2/6 2764T Experimental Investigatioti of S/024/61/000/004/005/025 E191/E581 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 276L41 Experimental investigation of s/o24/61/000/004/005/025 E191/E581 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 Card 4/6 27647 Experimental investigation of ... S/024/61/000/004/005/025 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 Card 5/6 27647 Experimental investigation of ,,, s/o24/61/000/004/005/025 I E191/E581 wake and therefore low total pressure losses.

Part Ono dealt with the limits of the regulating characteristics of the vehicle system. The attainable variation ranr,-e for flow rate q and exhaust,velocity V is investigated as a function oil :1-Mximum jet thrust power N The optimiLn control of the thrust vector, V and X are discussed under the coMNions 6 -~Ww (V) < NO. < V""< V (1) Car, ACCESSIOIN' NR: AP4026965 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- general 'expression is derived for the optimal correction rwmeut tion, and a distribution.
