Description
This ARDEC facility consists of subsonic, transonic, and
supersonic wind tunnels to acquire aerodynamic data. Full-scale and
sub-scale models of munitions are fitted with sensitive laboratory
instruments and mounted in the wind tunnels to measure free-flight
aerodynamic characteristics such as stability, drag, spin rates,
fuze arming, etc. The facility can accommodate munitions of all
types, from small arms to large caliber anti-tank, mortar, and
artillery rounds. In most cases the items can be tested at tactical
flight conditions.
Aerodynamic information can also be collected on objects other than
projectiles, including submunitions. A low-speed, low-turbulence
wind tunnel has been procured and the wind tunnel staff is
currently working to get this facility on-line. This wind tunnel
may be used for analyzing UAVs, grenades, and other items subject
to low speed conditions.
The wind tunnel staff has access to fabrication shops and rapid
prototype facilities enabling test item modifications to be made
quickly. This facility also has a physical property measurement
lab, for measuring the mass, center of gravity and moments of
inertia of inert items. A small-scale temperature conditioning
chamber is also available for items that must be tested at
non-ambient temperatures.
The facility can conduct work for contractors by implementing a
Test Service Agreement. In 2008 testing was completed for subscale
105mm and 120mm guided munitions, full scale control mechanisms of
105mm and 120mm guided munitions, grenade ribbon deployment, and
other proprietary programs.
