SOLRAM - Solid Rocket Motors

Obiettivo

The goal of SOLRAM Project is to develop at CIRA competences in the field of solid rocket motors (SRM). In particular, the main objective is to develop a methodology for the analysis of combustion chambers of solid rocket motors, that allow to support the design phase of a SRM, providing reliable evaluation of heat fluxes on the internal walls of the chamber and of the phenomenon of pressure oscillations inside the chamber itself.

The development of these competences is on one side propaedeutic to the VECEP Project (inserire link al progetto), in which CIRA supports AVIO for the design of VEGA-C launcher, and on the other side allows to improve the acquired knowledge, also by using in-house CFD codes for the calculations.

 

Attività nel progetto CIRA

SOLRAM Project is fully developed internally at CIRA, and is divided in two main branches:

  • Identification of analysis methodologies of the phenomena of interest and validation by means of literature test cases
  • Applications on geometries representative of full scale motors

The phenomena of interest are initially studied from a theoretical point of view, and the numerical methods and experimental data available in literature are analysed. Successively, the selected test cases shall be performed and compared with experimental data for code validation.

At the end of this first phase, that will have a duration of 20 months, the validated numerical tools shall be applied to geometries representative of real scale motors.

The last two months shall be finally devoted to an exploitation activity and to the definition of a roadmap for future developments.
