streamlining a wing in subsonic gas flow, thermal condition of gas in a 
boundary layer, influence of Reynolds number on jet augmentor, gas-dynamic 
control of nozzles, and ballistics of unguided rockets. 
In the field of aeroengines, the Institute has made studies of 
flame ignition in aircraft engines, stability of gas-engine turbine-rotor 
parts, high-temperature gas turbines, ramjet engines, roller bearings in 
turbojet engines, high-pressure centrifugal compressors, heat exchangers, 
heat-exchange cooling by evaporation, turbojet engines at subsonic flow, 
turbine discs, combustion in a turbulent stream restricted by walls, direct- 
flow combustion engines, turbojet thrust, temperature of blades and gas 
surbines with air cooling, thermal input of turbine blades, gas flow in 
turbines, heat transfer of turbine blades, combustion and turbulent flow, 
internal heat exchange during transpiration cooling through porous metal, 
heat-production rate during vibrating flame propagation and combustion in 
gas turbines. 
In the area of structural properties, studies have been made of the 
fatigue and thermal fatigue of metals, plastic deformation, creep, stability 
of structures, stability of movement, thin-wall structures, thermal stresses 
in thin-wall structures, stresses in shells, thin-wall beams, vibration 
analysis, aircraft structural analysis, solution of equations for wing 
vibrations, determining elastic modulus by resonance techniques, high- 
pressure tanks and bottles, function of monolithic slabs, wings, and ribs, 
and landing-gear mechanisms. 
Instrumentation of various types has been studied, including micro- 
motors, gyroscopes, and the stability of gyroscopes, automatic control 
systems, radiospectroscopic equipment, beta emitters for the elimination of 
static charges, and storage-cell batteries. 
In the area of metallurgy, studies have been made of steel for 
bolts and connectors, the manufacture of bolts for high-temperature appli- 
cations, heat treatment of upsetting tools, and ball bearings. 
Fabrication studies have considered the cost of unit-assembly 
operations, shaping of turbine blades for subsonic flow, cold bending, 
riveting light alloys, structures, bending and stretching of profiled com- 
ponents, milling and machining (e.g., gang milling of sheets), machining 
of high-strength and heat-resistant alloys, cast iron, and anodizing, 
The Institute publishes a Trudy.
