Members of the Tunnel 9 team are pictured with the electrical rectifier unit recently put into use. The unit, which was first delivered and installed in 2011, will replace an approximately 50-year-old power unit at Tunnel 9. Pictured from left are Electrical/System Engineer Tao Lee, Controls Engineer/Lead Controls Technician Ray Schlegel, Lead Electrician Ed Tierney, Chief Facility Engineer Nick Fredrick, Electrical/Data System Engineer Joel Barr and Test & Evaluation Engineer Inna Kurits.

The Hands-On Science Center runs the Air Force Science, Technology, Engineering, and Mathematics program on behalf of Arnold Air Force Base. The grant money allows the HOSC to fund events such as S.T.E.M. camps, glider academy, FIRST® teams and many more S.T.E.M. related events and education.
The AEDC J5 Large Rocket Motor Test Facility exhaust system will be refurbished for future facility operation during the Hypersonic Test Capability Improvement project. The HTCI project will transform J-5 into a large-scale clean air variable Mach test facility with extended runtime capabilities. (AEDC photo)

The existing J-5 Large Rocket Motor Test Facility at Arnold Air Force Base is undergoing removal of antiquated components in preparation for facility renovations. A team of AEDC engineers is heading up the Hypersonic Test Capability Improvement project which will totally transform J-5 into a large-scale clean air variable Mach test facility with a longer runtime than any facility of its kind.

Above is an example of the overset meshing that can be generated with Pointwise. Overset meshing is used when multiple meshes are needed to better capture complex shapes like those of modern aircraft and test facilities at AEDC.
This dragonfly image is an example of a computational mesh generated with Pointwise software, used by AEDC engineer to perform computational fluid dynamics, or CFD, for a wide variety of flight conditions and physical environments.
In the diagram, the first image is of a rotor fan surface geometry that was the result of the laser scan. The second image shows computational fluid dynamics (CFD) mesh that was generated from the surface and then used to produce the CFD results. The third image shows a portion of the CFD flowfield and the pressure of the air as it goes through the fan. (Image Provided)
