A-10 "Warthog" testing in 16-T

A model of an A-10 Thunderbolt II, more commonly known as “The Warthog” due to its unique shape, recently underwent a pressure-sensitive paint (PSP) test in Arnold Engineering Development Complex’s (AEDC) 16-foot transonic wind tunnel. PSP was used to obtain surface pressure data on the model. The photo above shows a rear view of the A-10 model during testing in 16T. The A-10 is the only U.S. Air Force aircraft designed to be specifically used for close air support. The aircraft is notorious for its maneuverability at low speeds and low altitudes and its accurate weapons delivery.

VKF Modernization Program Team celebrates Zero Accident AwardVKF Modernization Program Team celebrates Zero Accident Award
VKF Modernization Program Team celebrates Zero Accident Award

Earlier this month, Aerospace Testing Alliance (ATA) team members of the AEDC von Kármán Gas Dynamics Facility (VKF) Modernization Program celebrated with barbecue and all the trimmings. Team members were honored with a series of luncheons at the Carroll Engineering Analysis Facility, Model Shop and VKF in recognition of their receipt of the “Jacobs Zero Accident Award.” The award is presented annually by Jacobs, ATA’s managing partner, to projects whose teams have worked 250,000 consecutive hours without an injury of motor vehicle incident. Catherine Plunkett, Director, ATA Safety, Health and Environmental congratulated these winners for demonstrating real leadership towards world-class safety and validating the level of safety excellence that all of us can strive to achieve. Projects included in this achievement were the VKF Modernization Test Investment Planning and Programming (TIPP), Upgrade V-Plant Controls, Tunnels A,B and C (ABC) Modernization TIPP, ABC Data Acquisition System, ABC Operations Center, ABC Shadowgraph/Schlieren, and Tunnel A Nozzle and Diffuser Actuators and Controls.

Employees get a closer look at unique AEDC tunnels

Arnold Engineering Development Complex (AEDC) test engineer, Shannon Tibbals (right) and AEDC outside machinist, Greg Crabtree, get an up-close look at a nozzle in the von Karman’ Gas Dynamics Facility (VKF). VKF includes Tunnels A, B and C and are unique assets in the United States because they are continuous flow with the ability to sustain maximum speed for several days. Improved performance, productivity and reduced energy consumption are expected as part of a recent upgrade.

B-52 weapon-bay modifications implemented due to separation tests at AEDCB-52 weapon-bay modifications implemented due to separation tests at AEDC
B-52 weapon-bay modifications implemented due to separation tests at AEDC

AEDC set a record with the largest aircraft model (10 percent scale model) by conducting B-52 Stratofortress store separation tests. The testing was requested from the B-52 Program Office to look at the scope of the internal weapons bay upgrade to include additional multitude of weapons that previously had not been released from the B-52 weapons bay. Due to results and data generated from tests, modifications are currently underway to increase the B-52’s guided-weapon capacity. The increased capacity will enable the Joint Direct Attack Munition (JDAM), Joint Air-to-Surface Standoff Missile (JASSM), Miniature Air Launched Decoy (MALD) and the MALD Jammer to be carried internally. From left, J.T. Thompson, Aerospace Testing Alliance (ATA) captive trajectory system project engineer, discusses the B-52H model with Gary Cunningham, ATA lead outside machinist, in the AEDC Propulsion Wind Tunnel 16-foot wind tunnel between store separation test runs.

Wind tunnel spacers ‘under pressure’

Roger Johnson, an instrument technician in the Technology & Analysis Branch, installs strain gauge instrumentation and wireless telemetry transmitters in new carbon composite rotor blade spacers, produced by Matrix Composites, Inc., for a spin test at Wright Patterson Air Force base. The blade spacers provide equal spacing and stabilization for the nearly 6-foot blades in the Propulsion Wind Tunnel 16-foot Transonic test facility C-1 compressor. The spin test will analyze what type of stresses and loads the spacers can withstand. The spacers will be installed in the C-1 compressor for further loads and temperature data acquisition and analysis. (Photo by Rick Goodfriend)
