AEDC teams improve design engineering capability

ARNOLD AIR FORCE BASE, Tenn. – Arnold Engineering Development Complex is in high demand for testing.

In order to help meet that demand, AEDC Test Operations and Sustainment, or TOS, contractor, National Aerospace Solutions, LLC, expanded its design engineering staff in 2019 to support capital projects, test programs and the overall AEDC mission. But without the proper tools for the job, new team members would be left spinning their wheels.

Replacing decades-old exhauster motors expected to increase reliability, availability for testing base wide

ARNOLD AIR FORCE BASE, Tenn. – Exhauster motors near the Arnold Engineering Development Complex (AEDC) Engine Test Facility at Arnold Air Force Base are being replaced after being in service since at least 1958.

The motors, referred to as the A and B exhauster motors, have been used to exhaust up to a combined total of 1,100 pounds of air per second during testing.

Craftsmen keep largest wind tunnels in the world running at peak conditions

ARNOLD AIR FORCE BASE, Tenn. – They are considered indispensable.
Those at the National Full-Scale Aerodynamics Complex at Moffett Field in Mountain View, California, who observe their contributions every day agree the craftsmen employed there are not only integral to the work at NFAC but play a vital role the Arnold Engineering Development Complex mission as a whole.

“They are essential,” said NFAC Branch Manager Jeff Johnson. “We couldn’t perform this mission without them.”

Team members’ innovative methods advance test operations for AEDC hypersonic propulsion facility

ARNOLD AIR FORCE BASE, Tenn. – Improvements by team members of the Arnold Engineering Development Complex (AEDC) Aerodynamics and Propulsion Test Unit (APTU) at Arnold Air Force Base have prevented unscheduled downtime and avoided equipment damage at the facility.

Adam Webb, an electrical engineer for the Test Operations and Sustainment (TOS) contractor, National Aerospace Solutions, improved upon software for the rectifiers by enabling it to detect an unsafe condition and restore the rectifier to normal operations, preventing damage to expensive equipment. A rectifier is an electrical device that converts alternating current to direct current.

NAS donation helps establish a sensory room at Hands-On Science Center

ARNOLD AFB, Tenn. – After doing her research and realizing there are limited activities locally for children with special needs, Taryn Sjostrom, a Tullahoma mother, reached out to individuals at the Hands-On Science Center about creating a sensory-friendly room.

“The idea started with a family vacation to Dollywood,” Sjostrom said. “It was such an amazing experience to be able to go and have what is considered ‘normal’ family fun. Having a child with autism, I know how hard it can be sometimes to do these things.”

AEDC testing cost-, time-saving water line repair method

ARNOLD AIR FORCE BASE, Tenn. – When it’s possible to increase operational reliability while minimizing the cost and disruption caused by maintenance, it’s a win-win.

Arnold Engineering Development Complex team members are implementing a trial run of such a solution to the problem of leaks in raw water pipes at Arnold Air Force Base. Raw water is used in the cooling systems of the test cells on base.

3D printing successfully used to fabricate discontinued part for lube oil system

ARNOLD AIR FORCE BASE, Tenn. – When a decades-old part could no longer be purchased, the Plant Operations and Maintenance team at the Arnold Engineering Development Complex Engine Test Facility at Arnold Air Force Base coordinated with members of the Condition Based Maintenance group, or CBM, to determine how best to recreate the piece.

The most economical solution was determined to be 3D printing the part, a circuit breaker handle used to supply a 20 horsepower, 480-volt alternating current motor to the lube oil system, which directly supports two of the process air compressors for C-Plant.

Tunnel 9 personnel provides guidance for hypersonic experiment

ARNOLD AIR FORCE BASE, Tenn. – When those conducting Air Force-sponsored basic science research in hypersonic aerodynamics needed some advice, they relied upon the expertise of engineers and technicians at AEDC Hypervelocity Wind Tunnel 9 in White Oak, Maryland.

Earlier this year, personnel from Tunnel 9 provided instrumentation installation training to members of the research team from the Johns Hopkins University Applied Physics Laboratory (JHU-APL) in Laurel, Maryland, working on the BOLT flight experiment.
