Arnold Center

U.S. Air Force Arnold Engineering and Development Center (AEDC).

Since 2001, the 16 Foot Transonic (16T) Propulsion Wind Tunnel at AEDC has been using TestVIEW, the predecessor to Jacobs' Test SLATE, to perform aerodynamic evaluation testing for most of today's military flight programs

The capabilities of this facility are unmatched in the world. For example, imagine a Tomahawk cruise missile suspended in the 16 foot by 16 foot test section of a wind tunnel with the wind at near supersonic speeds. Then, imagine igniting its live, fueled engine, enabling it to exert thrust against its tethers into the wind generated by the massive tunnel fans.

Tests like these, as well as automated aircraft model pitch-pause and continuous sweeps, are common for this facility. These entire processes are automatically sequenced and controlled by TestVIEW through a variety of complimentary hardware subsystems. In addition, using TestVIEW's "proceed when pre-defined conditions are met" functionality has enabled AEDC to minimize test time for each individual test run, greatly improving facility productivity and throughput.

In more recent years (2012-2014), Test SLATE has been installed in the von Karman Facility (VKF) and the 4 Foot Transonic Wind Tunnel, also located at AEDC.

NASA

NASA Ames National Full-Scale Aerodynamic Complex.

The NASA Ames National Full-Scale Aerodynamic Complex (NFAC) is a wind tunnel with both an 80 foot by 120 foot test section and a 40 foot by 80 foot test section. Brought back on-line in late 2007, one of real draws of this facility --other than its simply massive test sections -- is its ability to test full-scale rotary aircraft

The Department of Defense revived funding for the de-commissioned facility and added capability unmatched throughout the world. Jacobs' Test SLATE was selected as the data control and measurement system.

Unique to the NFAC system is its capability to convert analog channels from a time-based measurement to a rotary-position-based measurement in real-time (i.e., converting 496 measurements every ~50 micro-seconds). Including all the measured channels and calculated variables, the system stores nearly 20 million data samples per second, which is almost 5 terabytes of data per hour if stored at a continuous rate.

Windshear

WindShear (NASCAR) Aerodynamic Wind Tunnel.

The world's first commercially available aerodynamic wind tunnel with a rolling road surface provides 180 MPH wind and a 180 MPH moving ground plane for motorsports teams to fully simulate aerodynamic track conditions in a repeatable test environment. 

Operations personnel use Jacobs' Test SLATE to orchestrate fully-automated test sequences that adjust wind speed, road speed, vehicle yaw against the airstream, and independent wheel ride height settings. Similar capabilities exist in proprietary Formula 1 wind tunnels, but not with the comprehensive automation available using Test SLATE at Windshear. Due to the competitive nature of racing, race teams need assurance of data security, which Test SLATE provides, while also providing each customer with real-time access to their data during testing to enable on-the-fly decisions.

Ford Drivability

Ford Motor Company Drivability Test Facility (DTF).

Jacobs designed, built, and operates a complex of three wind tunnels and two soak rooms for Ford, brokering the unused facility time to competitors and suppliers, all while maintaining the strictest confidentiality and security.

TestVIEW, predecessor to Test SLATE, provides operational control of all the test facilities within this complex, using a common set of software for all of them — from wind tunnels to soak rooms — enabling cross utilization of operations personnel and integrated sharing of data and test vehicle configuration information. The test automation tools within TestVIEW and DTF have been instrumental in helping reduce Ford's overall product development cycle time.
