A new injector head based on a new mixing element proposed by Energomash's engineers provides an increase of the process stability in the jet engines RD-107, RD-108, comparing to a prototype engine. New technological improvements are tested on the jet engines. An increase of thermoresistance of camera inner walls and injectors ensures reliable work of engine in different modes of operation. These jet engines have been already exploited as the component in RN "Soyus FG" in the both variants - load carrying and piloted.

BASIC CHARACTERISTICS AND STRUCTURE OF INTRINSIC QUASISTATIC MICROACCELERATIONS OF A SATELLITE
The residual quasistatic intrinsic to a spaceship field of microaccelerations are a principal characteristics of an exploited satellite intended to carry out physical experiments such as melting, crystallization, sedimentation, etc. The structure of microaccelerations vector field is analyzed in order to determine characteristics of microaccelerations field in terms of location of instantaneous pole, dimensions and orientation of the isograviellipsoids. In the case of constant orientation of the satellite with respect to the orbital co-ordinate system the effect of compensation of different microaccelerations components is described.

TURBULENT STRUCTURE OF A TWO-PHASE FUEL JET. FRACTAL DIMENSION OF AN EMISSION PLUME
The problem of working out of new approaches and methods of quality control of nozzle units in internal-combustion engine is studied. Fractal dimension of an emission plume of the two-phase fuel jet intended to use as a quality criterion of mixture forming is discriminated. The results of experimental research are presented.
