CED prides in its expertise in providing optimum solutions for mechanical devices and systems for a wide range of applications, especially those utilizing pyrotechnic and/or pneumatic power sources – often referred to CAD/PAD (Cartridge Activated Device/Propellant Activated Device) or ECS (Energetic Components and Systems). CED understands that the proper design methodology of such devices or systems must incorporate careful understanding of the physics involving the thermo-fluid aspects as well as the structural aspects that are simultaneously present in pyrotechnic/pneumatic devices. Due to the multi-physics nature, pyrotechnic science has often been considered an “art” and the applications heavily relied on experimental iterations. However, it is not only possible, but also crucial to establish a good analytical model that captures the essential processes involved in a pyrotechnic event for optimum design and manufacturing of such devices.
CED’s proprietary ballistics software, called CIBAC (CED Internal Ballistics Analysis Code), provides the analytical tools to model and simulate pyrotechnic events including the combustion, thermodynamics, fluid mechanics, heat transfer, and solid mechanic aspects of pyrotechnics. Using carefully trained engineers, CIBAC is used routinely at CED and has been proven to successfully predict and simulate performances of numerous pyrotechnic and pneumatic devices. This analytical tool allows CED to be both cost and time-efficient in design and production. CIBAC, along with CED engineering’s vast industry experience, offers a comprehensive tool for failure investigation, test fixture design, risk analysis, and system integration.
Additionally, CED uses multiple analytical and simulation tools including:
- Computer Aided Design (CAD) – Creo 2.0 w/ Windchill 11.2 and AutoCAD 2015
- Electrical Computer Aided Design (ECAD) – Altium Designer, OrCAD and P-SPICE
- Finite Element Analysis (FEA) – ANSYS Workbench Version 16 and Creo Simulate
- Data Analysis – DADiSP, Matlab
- Shock Physics/ Explicit Hydrocode – ALE3D and CTH
- Thermal Chemical Equilibrium Code – NASA CEA and PEP
