No.  50  Elaboration of high effective electrodes with multiple
increasing longevity for thermoionic converters (TIC) of heat energy
into electrical one of double purpose.

        Intensive investigation on electric current sources based on
nuclear thermoionic converters (TIC) has been carried out, designed to
obtain power in the range of 10KW-10MW relative to the needs of space
satellites for communication.  Experience has shown that increase in
longevity and effectiveness is required.  Current work on designing the
cathode of the converter in the form of a cylinder with nuclear fuel
inside has proven most effective.  The method of creating the cylinder
is unique.  The cathode  made of the alloy of tungsten and molybdenum
crystals with small additions is formed as single crystal rods, then
strips are cut off with surface thickness ~1.5 mm thick.   These strips
are twisted to form a spiral and the spiral joints are welded to form a
cylinder, followed by further treatment.  This technique practically
eliminates the difficulties formerly experienced.  The electrodes have
been called "monoside."

        The results of the present work have shown an increase in
longevity with the potential of much lower creep rate (1000 x) at high
temperatures. The target conditions are formulated to obtain 'monoside'
tubes with service of more than 105 h (with electrode spacing 0.2 mm and
conditions 2070 K, 10 MPa ) with vacuum work function ~5.2eV.

No. 230  Development of optical correlation systems for analysis of
statistical objects and optical fields.

This project purports to convert military applications for optical
information processing, including analysis of statistical field's
parameters, to the design of a new generation of rapid analysis devices
and a new generation of meteorological equipment. Extensive use of chaos
theory and fractal geometry concepts are to be used when the
applications involve large-phase inhomogeneities which require looking
for new parameters characterizing an object's structure and field 
simultaneously.

For example:
- correlation chaos dimensionality associated with harmonics whose
periods have no least common multiple; spatial field structure can be
represented using this parameter;
- fractal dimensionality characterizing self-similarity of the object
and field structure allows stand-up of low-dimensional signals against
high-dimension noise, both spatial and temporal;
- estimation of an object structure in the aspect of self-similarity.

Applications using the above possibilities allow important problems
to be solved; diagnostics of double stars in astronomy; diagnostics of
spatial and temporal structure of blood vessel currents allowing
separation of laminar and turbulent flows. The project realization will
produce equipment for real-time control of roughness parameters of
mirror and low-reflecting surfaces in the range of roughness from
0.002-0.02 mm as well as control of arbitrarily shaped surface quality. 
Plus one channel correlation monitoring systems dealing with artificial
objects and biological structures characterized by an accuracy of ~0.1
of the probing radiation wavelength.

The project is grounded on current stochastic and chaotic oscillation
theory, methods for solving of inverse problems of optics, coherent
optics, holography and electronic data processing including algorithms
of computer signal processing.

No. 235 Development of new advanced material, based on the non-metal
nitrides for the exploitation at high temperatures and in aggressive
environment, using the methods of preliminary gas-thermal activation of
precursor powders.

        By methods of preliminary gas-thermal (hydrogen) activation of
precursor powders of nonmetallic nitrides BN, AlN, Si3N4, new advanced
materials are expected to be developed.  This development allows the
transfer of military and space developed techniques used to make
measurements under extreme conditions of vacuum, in aggressive gases
and liquid environments, at high temperatures.

        The experience gained will allow the development of nonmetal
nitride-based  high temperature gauges for use in  ferrous and
non-ferrous metallurgy by the contact methods with improved service
characteristics, and production of protective ceramic covers for high-
temperature thermocouples.

        The aim of the hydrogen-thermal processing of powders is to
remove the harmful impurities, to decrease the powder particle size and
improve the powder structure.  Using such powders will improve the
technology of materials produced and allow new materials with assigned
structure and service characteristics to be developed.

No. 306 Space-Time Light Modulators with Electron Beam Addressing.

        This project features the elaboration of the physical
principles of light-modulated screens for space-time light modulators
addressed by electron beams using materials featuring electron
stimulated phase transition.  The intent is the selection of optimal
technological regimes along with the creation of thin film structures to
secure maximum sensitivity at phase and amplitude light modulation due
to phase transitions in the light-modulated layer under the effect of an
electron beam; to study the nonequilibrium process relaxations depending
on material characteristics of such structures and electron beam
parameters; to optimize the structure parameters of phase and light
modulation to secure maximum sensitivity; and to construct an
electron-beam device and to adapt its application to the physical and
chemical properties of the light modulated screens.

        The project is based on results obtained investigating
semiconductors and thin films under the effects of an electron beam. In
particular, it was found that the applied electron beam resulted in
electron stimulated metal-semiconductor phase transition accompanied by
strong changes in the optical properties of the materials.  Because
of such properties both amplitude and light modulation can be realized.
The result is space-time light modulation with high resolution and
sensitivity, unlimited reversibility and significant depth modulation.
These characteristics along with easy operation make the system
compatible with known devices.

No. 335 The Working out of a Hybrid Integral Circuit of the Microwave
Receivers on the basis HTSC Resonators and Filters Combined with
Semiconductor Active Elements for Communication System.

        The project's aim is the development of an improved receiver for
an immeasurably weak input signal, the reduction of phase noise, and
for frequency stabilization and higher frequency selection. 
Developments will include superconducting components, integration
techniques, and thermal designs for cryogenic temperatures. These
developments have become feasible due to the discovery of high
temperature superconductors (HTSC) with resultant reduction of conductor
losses and higher quality factors (Q) in microwave systems.  The result
is a power or mass saving over conventional technologies in
telecommunication satellites, where low temperatures are readily
available.

No. 356 The development of the composite materials based on refractory
borides, carbides, ceramics, as well as technologies of obtaining from
them coatings with high level of corrosion and wear-resistant by
plasma-arc and electro spark methods.

        The intent is to replace high-alloying steels for tools, by
low-alloying steels, with wear- and corrosion-resistant refractory
compounds and ceramics, as coatings through the use of plasma arc or
electrospark alloying, to give improved service at high work
temperatures (1000oC). 

        It is anticipated that this relatively simple system will lead
to improved coating bonding and lower costs.  Preliminary work has shown
that wear resistance of spring steel has increased by 25x and carbon
steel by 100x using deposition of coatings based on refractory borides. 
Several new refractory phase alloys are suggested.

No. 407 The study of regularities and kinetic peculiarities of
interaction of transition metals and alloys with atomic hydrogen for
improvement of nuclear reactor safety.

        This project tackles the problem of atomic hydrogen penetration
into metal, in particular the metals of Group IV:  Ti, Zr, Hf, which are
regarded as most promising for reactor and tokamak shielding.  Based on
the initial studies the project aim will be to suggest protective
coatings for these metal products endeavouring to limit atomic hydrogen
penetration. Hydride transition metals of the GroupIV metals will be
studied.

        By means of a new kinetic method of investigation developed by
this group, hydride forming processes in transition metals can be
studied in a special vacuum plasmochemical gravimetric installation.
High pressure hydride phases up to 27 Pa can be observed and hydrides of
homogeneous hydrogen composition and with prescribed hydrogen content
can be made. Alloys of the Group IV metals will be studied and also the
influence of electronegative impurities (O,N) in the metal volume on the
phase transformation kinetics .

No. 459 The Initial Design of Business Aircraft (Antonov-5)

        Market analyses have shown a void in the CIS countries of
business-designed aircraft of the following types:

-  6-seat passenger plane (up to 550 kg cargo transportation) with
piston engine and unpressurized fuselage;
-  6-seat passenger turboprop (up to 500 kg cargo transportation) with
pressurized fuselage; and for a
-  10-seat passenger turboprop aircraft with unpressurized fuselage
(cargo transportation up to 880 kg.)

        Engines and other items are readily available in Ukraine for
aircraft manufacture.  Avionics equipment and interior components may be
required.

        Considering that available are skilled personnel who earlier
designed military transport, and that the high demand for aircraft
expected in Ukraine and CIS countries will be determined by market
research, and that wind-tunnels are available for testing, there is a
reasonable chance of a successful industry being borne in commercial,
business and personal aircraft.  Government and private investors are
being sought.

No. 489 Research and development of technology of finishing articles
from silica-containing hard natural stones meeting the quality
requirements of world market, with the aim to organize the production of
facing tiles on the basis of optical equipment released in conversion.

        This project employs techniques formerly employed in the
"Arsenal Plant," namely, the technology of finishing small-sized facings
of tiles. Rather than conventional microcutting with the help of
polishing suspensions containing hard abrasive particles, leaving
machining marks and defects on the as-machined parts, this process is
replaced by polishing by physico-chemical action of SiO2 which is
contained in the stone, with oxides of rare-earth metals (CeO2, etc.)
entering into the composition of the polishing tools, providing a high
reflectivity of surface and releasing the idiochromatic colour of the
stone.  The project includes development of special diamond abrasive
tools for finish grinding and preparation of the surface for polishing.

        This project will use the plentiful natural resources of granite
of Ukraine for improved domestic and industrial products:  fascia, tiles
for bathrooms, for flooring, and fireplaces, etc.

        The replacement of cutting tools where the toxic waters from the
conventional polishing based on free powders of Cr2O3 and CeO2, etc.
with tools wherein the CeO2 is bonded powder improves working
conditions. The concentration of CeO2 has decreased from 200  to 8 g per
liter of water, and is thus more ecologically acceptable.
