- Wind Tunnels
ACI supports various research programs in a wide variety of wind tunnels, including small-scale
to full-scale, low-subsonic to hypersonic facilities. ACI also excels in design, development and
operation of data acquisition systems (DAS) and various sensors. The facilities ACI supports
include the Unitary Plan Wind Tunnel (UPWT), Fluid Mechanics Laboratory (FML) and National
Full-scale Aerodynamic Complex (NFAC) at NASA/Ames Research Center, and four hypersonic
wind tunnels within the Langley Aerothermodynamics Laboratories (LAL) managed by the Ground
Facilities and Testing Directorate (GFTD) at NASA/Langley Research Center. ACI has also
supported test programs at Arnold Engineering Development Center (AEDC).
ACI supported a multi-year study of high angle-of-attack aerodynamics using a real F/A-18 Hornet
mounted in the 80- by 120-ft Wind Tunnel at NASA/Ames Research Center. The study included
post-stall directional control by fore-body blowing. ACI was responsible for over 5000 channels of
pressure data acquisition.
ACI supported a parachute deployment system in the NFAC using high-speed image processing. The
parachute is a part of the Entry/Descent/Landing (EDL) system of the Mars Science Lab, NASA.s new
robotic Mars rover scheduled to launch in late 2011. The parachute pack was ejected from the casing
by a mortar.
