Description:ROCket Combustor Interactive Design (ROCCID) provides a standardized methodology using state-of-the-art codes and procedures for the analysis of a liquid rocket engine combustor's steady state combustion performance and combustion stability. ROCCID also includes an interactive design capability for liquid propellant combustors. |

ROCCID is currently capable of analyzing mixed element injector patterns containing impinging like doublet or unlike triplet, showerhead, shear coaxial and swirl coaxial elements as long as only one element type exists in each injector core, baffle, or barrier zone. Real propellant properties of oxygen, hydrogen, methane, propane, RP-1, ethylene, and space storables are included in ROCCID. The properties of other propellants can be easily added. |
| The analysis models in ROCCID can account for the influences of acoustic cavities, helmholtz resonators and radial thrust chamber baffles on combustion stability. ROCCID also contains the logic to interactively create a combustor design that will meet input performance and stability goals. |

A preliminary design results from the application of
historical correlations to the input design requirements. The steady state performance and
combustion stability of this design is evaluated using the analysis models, and ROCCID
guides the user as to the design changes required to satisfy the user's performance and
stability goals, including the design of stability aids. Output from ROCCID includes a formatted input file for the standardized JANNAF engine performance prediction procedure. Sierra Engineering is currently selling our proprietary ROCCID 2006 version, which includes numerous enhancements and improvements over the original verions of ROCCID, and integrated EXCEL plotting. ROCCID 2006 also includes the capability to analyze the stability characteristics of some rectangular cross-section combustors. |
