SIBAC stands for Scot Interior Ballistics Analysis Code. SIBAC is composed of several major subroutines that address the physics described in the section, Essential Physics in CAD/PAD and ECS. The subroutines are mainly written in Fortran 90. SIBAC uses a text-based input file which contains the vital parameters of the device that is to be analyzed such as the propellants used, the internal volume, the surface area for heat loss, external forces, damping mechanism, flow passage information, and etc... The input file can easily be modified. The modular construction of SIBAC allows for an easy adaptation for various applications with different design approaches and device configurations. The outputs of SIBAC can also easily be used in other tools such as Finite Element Analysis codes (COSMOS or NASTRAN for example) or CTH for further investigation of the physics that are more suited for such tools. The following example shows the use of COSMOS in predicting stresses in the gas-generating component of BRU-44 B/A ejector used in B2 airplane.
