Technique of the research of characteristics of ignition of the condensed systems to variables heat flux

This paper presents a method for determining the ignition delay time of condensed systems when exposed to radiant heat flux on the sample surface. The heat flow through the focusing lens with the ability to move along the axis was applied to the sample. Changing the geometric characteristics of the optical system can be used for measurements of the ignition of samples condensed systems in a wide range of values

Dynamic Regime of Ignition of Solid Propellant

This article presents a dynamic regime of exposure of the radiant flux on the sample of gun-cotton. Obtained time the ignition of gun-cotton in the heating conditions of increasing heat flux in the range from 0.2 W/cm{2} to 22 W/cm{2}. A comparison of the delay times of the ignition when heated variable and constant heat flux

Influence of the local gas injection on the flow structure in the boundary layer

The results of an experimental and numerical study of the interaction of supersonic flow around an axisymmetric model, M = (2 [-:] 5), with a jet of gas injected locally into the boundary layer are presented

Study of heat transfer processes in the flowing part of hypersonic air-ramjet engine

The technique and results of the experimental-theoretical study of gas dynamics, heat transfer and the structure of gas flow in the flowing channel of a model hypersonic air-ramjet engine are presented for Mach numbers M (5; 6)
