Creo parametric cost4/6/2023 The Commercial Space Industry has seen rapid investment and growth, most famously from SpaceX, who's "Falcon Heavy" Rocket Claims to be able to get stuff in space for $1300 $/kg, which is over 1/10th the traditional cost! More recently prices have been dropping for two main reasons: Competition & Technology. This launch cost is a function of, among other things, the mass which you are lunching (moving mass burns fuel, duh!). Until now, the price of launching a satellite has been prohibitively expensive, with "typical" prices being near $22,000/kg ($10,000/lb). Commercial Space Travel Costsīefore we jump into the case study, let's recap why this is so relevant. This article walks through the process of capturing the load cases from a SpaceX Falcon Rocket, and using them to optimize an Optical Bracket on a CubeSat (similar to those shown above, courtesy of Cagri Kilic) using some of the latest tools in PTC Creo, such as Topology Optimization. However, with the advancement of hardware and software, a growing category of Structural Optimization tools are automating this computationally expensive and time consuming process. Optimization began as a manual "Designer in the Loop" process, which involved someone assessing the results of a series of analyses against their design criteria - for example, Factor of Safety. Fast forward a few generations, and now we are dependent on Computer-Aided Engineering (CAE) tools like Finite Element Analysis (FEA) an Computational Fluid Dynamics (CFD) to help us design, analyze, and optimize our designs. Not only did the "Space Race" of the 1960's launch the human race out of the grips of Earth's gravity, but it also launched Designers and Engineers out of the grips of hand calcs and slide rules and into the new, unknown world of Computational Physics.
