Combustion chamber thermal performance

The performance of propints is a unique function of the temp of the hot reaction products, their compn and their pressure. The pro-pint bums at constant pressure and forms a set of products which are in thermal and chemical equilibrium with each other. The multiplicity of the reaction products requires that the combustion chamber conditions be calcd from the solution of simultaneous equations of pressure and energy balances. This calcn is best performed by computer, although the manual scheme has been described well by Sutton (Ref 14) and Barr re et al (Ref 10). The chamber conditions determine the condition in the nozzle which in turn characterizes the rocket engine performance in terms of specific impulse and characteristic exhaust velocity...

With the nanotechnology, using nanoparticles or nanostructures, it is possible to obtain further improvement of the rocket performance. In particular, the combustion of nano-sized elements gives a significant increase of the thermal spatial gradient in the combustion chamber, with a consequent increase of...
