The Concept Of Air Launch Application For Russian Launch Vehicles (pp. 3 – 18)

M.M. Kovalevsky, S.A. Lemeshevsky, S.F. Teselkin, A.D. Tokhunts, S.N. Shevchenko

The article presents the rationale for the development of space transportation systems with air launch of space launch vehicles of light, middle and heavy classes. The application of surface-effect airborne ships for air launch of space launch vehicles are treated as perspective means for the solution of issues related to drop areas of stages, up-scaling of energy performances and reusability of space launch vehicles. The adopted Russian State Program for the development of screen-effect airborne ships of new generation implies the creation of screen-effect airborne ships with payload of 1000 tons. Meanwhile namely Russian space branch can and must be one of the main users of a new generation screen-effect airborne ships.

Keywords: air launch; surface-effect airborne ship; screen-effect airborne ship; launch site of drop area; transport plane; Upper Stage; payload; cold launch; high-altitude nozzle; «zoom» maneuver.

Archimedes Model In The Single Law Of The Growth Of Large Vortexes In Atmospheric Streams
(pp. 32 – 37)

A.G. Prudnikov, A.M. Podvalnyy

The reversal model of straight-line streams in the vortex tangle is presented for determining of the vortex growth and for the extension of the free vortex layer. It depends on local parameters at the point of support. The equations of continuum mechanics are solved for a vortex and a vortex layer. The kinetic energy of a vortex tangle is given for incompressible regime.

Keywords: large vortex; reversal model; kinetic energy; vortex structure; gasdynamic parameters.

S.A. Ermakov, S.V. Konstantinov, N.V. Kryazhev, I.P. Kuznetsov, Yu.G. Obolensky

Key problems are under consideration which relate to development of control actuator multichannel (reserved) system structures of passenger airplane control actuators operating in the summarization mode of forces on the common output member, i.e. control surface.

Keywords: control actuator multichannel system of passenger airplane; aerofoil plane; interloading of actuator power channels.

The Multicavity High Pressure Single Material Bottle (pp. 52 – 59)

G.N. Ustinov, A.I. Sokolov.

As for now, practical development of hydrogen as fuel has been limited to solving special problems. One of the important ones is the making of gaseous-hydrogen storage facilities. The paper has to do with analysis of the design of the high-pressure single-material multicavity bottle, which has not a maximum ratio of the pumped gas to the construction mass, but being superior to familiar designs in this respect. The bottle can be applied to the storage of hydrogen and light gases at petrol stations and as part of vehicles. The paper is a continuation of a search for designs superior to the investigated one [1] in the maximum ratio of the pumped gas to the construction mass. These designs may have an application in aerospace technology.

Keywords: storage facilities; multicavity bottle; light gases; gaseous hydrogen; high pressure; single material.
