RECENT DEVELOPMENTS AND CHALLENGES IN THE IGNITION AND COMBUSTION OF SOLID PROPELLANTS

ABSTRACT

It is of much interest to know (mostly from detailed experiments) the mechanisms involved in the combustion of solid propellants and as much as possible to describe them through modeling. The regimes thus investigated should be :
- ignition (reaching first decomposition and transitioning to fully developed flame),
- steady combustion (evolution with respect to pressure and initial temperature) resulting from the coupling between condensed and gaseous phases, including the behavior of added aluminium,
- response to erosive burning conditions,
- response to pressure (and velocity) oscillations,
(these last two topics being covered very briefly for the sake of space).
From such knowledge and modeling various results should be expected :
- orientations in the elaboration of new propellants for the tailoring of their combustion characteristics,
- prediction of the operation of compactly loaded motors (such as for hypervelocity missiles) which are submitted to erosive burning,
- prediction of the stability of the motor,
- prediction of the distributed combustion of aluminum, resulting in possible specific impulsion losses due to incomplete combustion, as well as in the accumulation of slag at the rear end of large boosters.
A conclusion is reached that much work has been accomplished, which has to be extended to the emerging propellants based on new ingredients, and which has to be integrated more and more, alongside the develoment of the description of the internal aerodynamics, into the prediction of the motor performance.
