Tunnel 9 staying in high demand

ARNOLD AIR FORCE BASE, TENN. – The prediction made years ago by the team at AEDC Hypervelocity Wind Tunnel 9 in White Oak, Maryland, has come to fruition, and their forecast of an increased workload was on point.

For the past several years, Tunnel 9 has been running at near to capacity. Tunnel 9 Director Dan Marren said the recent uptick in facility activity can be heavily attributed to what he described as currently the “hottest ticket” in aerospace – hypersonics.

Tunnel 9 returns from busy outage

ARNOLD AIR FORCE BASE, TENN. – For some the term “outage” may conjure up images of throttling down while the maintenance team takes control of the cell, using the downtime to recharge operationally before a return to full production.

But for the team at AEDC Hypervelocity Wind Tunnel 9 in White Oak, Maryland, the facility’s annual outage has been anything but idle.

AEDC team members resurrect 1996 software to assist in engineering analyses at Arnold AFB

ARNOLD AIR FORCE BASE, TENN. – Through a combined effort of AEDC team members, a 1996 pressure vessel hazard analysis software program was installed and made useable on a current system at Arnold Air Force Base.

Joshua Diller, an AEDC system administrator, explained that he found a way to install the analysis software, written to be used with Windows 95, so that it would run as needed to help with early engineering analyses related to pressure vessels.

AEDC T-11 engine test cell modified to expand its capabilities

ARNOLD AIR FORCE BASE, TENN. – The AEDC T-11 engine test cell at Arnold Air Force Base has been enhanced to perform a wide variety of research tests in addition to its primary role of testing small engines in a direct-connect configuration.

The Air Force Project Manager for upcoming technology tests in T-11, Joshua Osborne, explained that one of the largest benefits is that this provides a cost effective way to develop and prove needed test techniques at a lower scale or at the component level to reduce risk to high-cost advanced weapon systems.

The Air Engineering Metal Trades Council installs officers

ARNOLD AIR FORCE BASE, TENN. – The Air Engineering Metal Trades Council – AEDC’s largest union – installed its newly elected officers recently.

Jay Vandergriff retired Jan. 25 and passed the gavel to Alvin Cleek, who was elected as the Council’s new president. Cleek has worked at AEDC for 13 years and has been an ironworker for 33 years. He has served as chief steward for the ironworkers and carpenters for the past 9 years. Prior to that he was trustee and vice president.

Innovative analysis methodology making a difference for AEDC, Air Force and the warfighter

ARNOLD AIR FORCE BASE, TENN. – AEDC analysis team members have developed and demonstrated a first generation full frequency range screech analysis methodology for a re-heater on turbine engines to reduce instability when testing in the facilities at Arnold Air Force Base.

Innovative ideas like this one are common in daily work across AEDC and the U.S. Air Force, as the Air Force is known for its dedication in innovation and delivering war winning capabilities to the warfighter by inspiring and providing the necessary tools and support.

Test Support and Tunnel 9 teams to complete first remote installation of original AEDC data system

ARNOLD AIR FORCE BASE, TENN. – A team effort between personnel at AEDC Hypervelocity Wind Tunnel 9 in White Oak, Maryland, and Arnold Air Force Base recently facilitated the replacement of the 20-year-old Tunnel 9 system used to record, process and display test data.

Last month, Tunnel 9 completed the final installation and necessary sign-offs for its new Enterprise Data Acquisition and Processing System (EDAPS). EDAPS replaces the Legacy Data Acquisition and Recording Equipment (DARE) IX system used previously at Tunnel 9 and marks the first installation of EDAPS outside of Tennessee.

Tunnel 9 moves closer to 360-degree TSP capability

ARNOLD AIR FORCE BASE, TENN. – The team at AEDC Hypervelocity Wind Tunnel 9 in White Oak, Maryland, has for some time considered a 360-degree capability for tests involving temperature-sensitive paint, or TSP, and has worked for about a year on ways to achieve it.

Thanks to recent innovations developed after a customer’s need provided a push, the Tunnel 9 team’s TSP capability is now one step closer to painting the entire picture on wind tunnel models. The team built a prototype system mounted in the plenum of the T9 test cell tunnel to allow for data collection from the bottom of the test cell – the most challenging view from an engineering perspective.
