Downstream View of Test Section.
The rectangular test section is 7 feet high,
10 feet wide and 12 feet long, fabricated of structural
steel lined with marine plywood. The corners have 12 inch
fillets which house fluorescent lamps to provide
photographic lighting. Cross sectional area of the test
section is 68 square feet. Three inch wide vertical venting
slots in the side walls at the test section exit maintain
near atmospheric static pressure. A top door 8 feet wide by
10 feet long provides easy installation of assembled models
while a 34 inch wide by 80 inch high side door aft of the
test section allows access for personnel and smaller pieces
of equipment. Sixty-five square feet of plate glass and
acrylic windows assure adequate visual access to a model
photography from many angles. A system of remote movable
cameras connected to monitors in the
control room allow views of a model from several angles
at the same time. A turntable seven feet in diameter built
into the test section floor rotates with the external
balance but is isolated from the balance and has a separate
drive system. The test section sidewalls diverge about 1
inch in 12 feet to account for boundary layer growth.

Machine Shop
Main room of machine shop.
The machine shop provides support for tests
including the modification of models and building of model
mounting systems. The 1200 square foot area is
attached to the north side of the main building and provides
tables for model assembly and/or work. The shop
equipment includes:
-
Three mills
-
Turning Center and Manual Lathe
-
Band saw
-
Mig, Tig, and Stick welders
-
2 ft. X 3ft. granite surface tables
-
Disk sander

Grinder
-
Wood working equipment
The tunnel also has extra machine shop
support by the TEES machine shop located less than 10
minutes away. Most model changes and/or modifications can be
accomplished in house, by either the wind tunnel staff or
customer model support personnel. A 10 ft. X 12 ft. door
provides access to the shop and it also serves as the model
access to the wind tunnel building.

Control Room
The wind tunnel operators' control console is
located adjacent to the test section and is placed so that
the operator has a full view of the model during testing.
All switches, controls and instruments required for motor
starting, setting the test section velocity, positioning the
model attitude and regulating the high pressure air system
and electric drive system are on the console within easy
reach. Video monitors provide close-up views of the test
section and model. Immediately to the right of the operator
is the data acquisition station. A networked computer is
used to run programs that record and reduce data taken
during each run. Data can be sent to an online printer in
the control room as it is reduced. A video projection system
directly connected to a computer running a spreadsheet
program is used to display the current and future test runs.

Customer
Engineering Work Space
The customer engineering area is adjacent to
the control room and has approximately 200 sq. ft. of space.
It two computers with hi-speed internet access that run sequence displays
and have access to the test data files. In
additional, wireless internet and printer access is available for
customers who wish to use personal laptop computers. Table and desk
space for customer computers and data analysis is ample, and
the room can accommodate four people comfortably.

Ready Room
The ready room is used by the customer and
the wind tunnel crew to prepare models before they are
installed in the test section. The ready room is adjacent to
the actual test section, so it provides direct access
between tools and model parts to the testing area.
top↑
Conference Room
A conference room is available on the ground
floor of the building for conference calls with the company
management or other engineers during the test period. The
conference room is isolated from the main traffic areas and
provides a low noise level and a speaker phone. The room is
also equipped with a video player and television that can be
used to review test information.
