Comet Customer Presents New Project Results at SPIE Optics+Photonics Conference

Dr. David Thomas, senior project engineer at The Aerospace Corporation, presented how the Comet™ workspace streamlined their interdisciplinary analysis process to achieve significant cost and time savings at the SPIE conference at the San Diego Convention Center on August 6, 2009.

Dr. Thomas’ paper “Collaborative Design and Analysis of Electro-Optical Sensors” details how complex products are best developed in a collaborative design environment where engineering data and CAD/CAE results are shared across engineering discipline boundaries. His paper and presentation describes how Comet’s performance engineering workspace allowed Electro-Optical (EO) sensors to be developed in a streamlined manner by rapidly conducting integrated Structural/Thermal/Optical (STOP) analyses of a critical lens subassembly in a flight payload.

Comet software brought a template-based approach to the multi-disciplinary team of engineers which was used to drive existing structural, thermal and optical software tools for the validation of an unconventional thermal control approach for maintaining focus of the visible channel of a flight payload over its expected thermal environment. This integrated analysis process provided superior physical insight into how the thermal control approach actually works.

Dr. Thomas’ team was able to perform interdisciplinary system level analysis in a single day using Comet’s integrated STOP process – using their old process this same complex analysis would take several days or weeks to complete. The use of templates allowed rapid turnaround of each analysis, providing near real-time support of the thermal-vacuum tests being conducted. Additional savings will be achieved when the template is updated and reused for future analysis work on this project and on other, similar projects.
