Exhaust Jet

Five processes controlling the production of soot from gaseous hydrocarbons are distinguished: gas reactions producing radical fragments on which nucleation may begin; nucleation; coagulation; growth; and oxidation. A fundamental model capable of taking into account all these processes is described. The model is applied to the conditions of a practical rocket engine, in which production of soot in the exhaust jet is governed by the rate of pyrolysis of methane in the chamber. Predictions made for these conditions agree with experimental results. The rate controlling processes and key intermediate species are identified.

The Moment

In the dynamic and quasi-static statements, the issue of non-stationary deformation and stability of the solid propellant rocket engine (SPRE) was approximately solved. It is modeled by a thin, smooth cylindrical shell, inside of which, on a part of its length, there is an elastic base corresponding to a gradually burning powder charge. A pressure wave is moving along the outer surface of the body, simulated by the running load. The deformed state of the shell is considered axisymmetric and is determined on the basis of the moment theory of the shells. For diverse variants of mounting the ends of the shell in a closed form, expressions were obtained for the critical velocity of the load. Examples were considered.
