I recently installed and started teaching myself the Creo suite of tools. I needed a replacement for AutoDesk Inventor. I’ve posted the finished product of the tutorials for building a piston/ piston shaft. I would like to reach the same capability I previously held with Inventor. For those of you not familiar with Creo, Wikipedia offers this:
Creo Elements/Pro and Creo Parametric compete directly with CATIA, Siemens NX/Solidedge, and SolidWorks. The Creo suite of apps replace and supersede PTC’s products formerly known as Pro/ENGINEER, CoCreate, and ProductView.
I previously used AutoDesk Inventor to make the Gulfstream GV/ G550 model (Gulfstream G-V CAD). Dr. Charles O’Neill has reproduced a version of this model in CATIA. The article describing the model is here: https://charles-oneill.com/blog/gulfstream-gv-g550-cad-model/ His model is available on GrabCad: https://grabcad.com/library/gulfstream-gv-g550-low-fidelity-2
Gulfstream GV / G550 CAD Model
Engineers/pilots will notice, on my model, the abscence of wingtips and the exact airfoil is reproduced as best as possible for being lofted from drawings. This drawing was intended as low fidelity to facilitate a proposal. It meets those requirements.
Completing the Creo tutorial required some breakdown between both the text and the videos provided. Completed exercises are shown below.

Christopher R. Simpson built a rocket to pass his Level 1 (L1) certification from the National Association of Rocketry (NAR). The rocket was a kit from Madcow Rocketry; the “Frenzy,” . The RX1 used an Aerotech H550ST-14A, “Super Thunder,” motor with a total impulse of 71.9 lb-sec and a burn time of 0.57 sec. Construction of the rocket, flight, and recovery are reviewed to analyze and critique operations.

A big thank you to Karson Holmes for certifying/critiquing me and William Ledbetter for making the trip to watch the fun take off! Also, a special thanks to Alabama Rocketry for allowing me to use their adapter.

I will be giving a demonstration of FreeFlyer on Thursday, September 28 at 2:00 pm in SERC 3070. Faculty and Students feel free to drop on by! I have attached the flyer, here: FreeFlyerWithAttitude
Christopher Simpson will present a FreeFlyer demonstration, “FreeFlyer with Attitude,” on Thursday, September 28, 2017 at 2:00 pm in SERC 3070. FreeFlyer with Attitude will showcase the high-fidelity flight dynamics software with a Earth imaging satellite mission plan with specific pointing requirements. FreeFlyer is currently used on several NASA missions, including the Magnetosphere Multiscale (MMS) mission which set the record for closest flying formation at 7.2 km in September of 2016. Mr. Simpson recently interned with a.i. solutions, Inc. over the summer and worked with the FreeFlyer Tech Support team. He recently graduated with his B.S. in Aerospace Engineering and Mechanics from The University of Alabama in May 2016. He was recently awarded a SMART scholarship from the Naval Air Warfare Center – Weapons Division, China Lake. He is pursuing his Ph.D. at The University of Alabama under Dr. Charles O’Neill.
