Major savings occur as part of AEDC wind tunnel improvement program

The feedthrough assemblies for the Test Article Control System (TACS) and Data Acquisition System (DAS) used at the 16-foot transonic (16T) wind tunnel were recently replaced, saving AEDC more than $1 million. Pictured is a new feedthrough undergoing vacuum testing in the Space Systems Test Facility (SSTF) Lab at AEDC. (Photo provided)

16T project team determines more efficient process for disconnect panel fabrication

This is an example of a new disconnect panel for the 16-foot transonic wind tunnel (16T) Test Article Control System (TACS) and Data Acquisition System (DAS). One panel would usually take at least a month or two to complete in-house for $1,300 but is now being completed for $300 in just two weeks. (Photo provided)

16T project team determines more efficient process for disconnect panel fabrication

Terry Rayfield, ATA Senior Controls Engineer, at right, and Dale Shultz, instrument technician, work on putting terminal strips into one of the new disconnect panels for the Propulsion Wind Tunnel facility 16-foot transonic wind tunnel (16T). The disconnect panels, which are part of the 16T Test Article Control System (TACS) and Data Acquisition System (DAS), are used to provide a clean interface between system input/output hardware and field devices.

Randy Vinke, an ATA electrician with the Propulsion Wind Tunnel (PWT) Facility Test Operations group, installs wires for the interface panels that are used to connect the test model instrumentation to a data system. The installation occurs in the PWT four-foot Transonic Wind Tunnel (4T) Captive Trajectory Support (CTS) system, which contains a newly designed and fabricated mechanism that enables a test model to have six degrees of motion: pitch, roll, yaw, axial, horizontal and vertical. The CTS is used to conduct staging and store separation testing. (Photo by Rick Goodfriend)

Dennis O’Dear (left) and Keith Gipson (bottom, right), both ATA outside machinists, install newly designed and fabricated flexible nozzle actuators in the Propulsion Wind Tunnel four-foot transonic wind tunnel (4T) at AEDC. The actuators are electromechanically driven ball-screw jacks which move the flexible top and bottom plates in the 4T tunnel closer together providing variable Mach numbers or wind speeds during a test.

Congressman DesJarlais views AEDC progress

Congressman Scott DesJarlais (second from left) tours the Propulsion Wind Tunnel 16-foot Supersonic Tunnel at AEDC during a visit on April 8. The wind tunnel test aerodynamic flows for flight systems and has a capability of achieving Mach speeds up to 4.75 or approximately 3,000 mph. DesJarlais also visited the von Karman Gas Dynamics Facility, the Arc Heater Facility and the Space Threat Assessment Testbed to see facility capabilities and upgrades. Pictured with DesJarlais, left to right, is AEDC Propulsion Wind Tunnel Test Branch Technical Director Wayne Hawkins, DesJarlais’ staff member Isaiah Robinson and AEDC Commander Col. Raymond Toth.
