More Photogrammetry for Wind-Tunnel Testing
AIAA Journal, 2002Recent work by Liu et al. has led to renewed interest in the use of photogrammetry for measuring the position, attitude, and deformation of a test article in a wind tunnel. The present research expands on this work with a more comprehensive mathematical model that can be used not only for determining the interior parameters of the cameras, but also the

Wind-Tunnel Testing of Structures
Journal of the Engineering Mechanics Division, 1977Civil engineers, architects, and city planners are beginning to use design data derived from wind-tunnel tests as extensively as aeronautical engineers have for many years. This evolution of wind engineering has been made possible by development of special meteorological wind tunnels that simulate essential characteristics of natural boundary-layer ...

48th AIAA Aerospace Sciences Meeting Including the New Horizons Forum and Aerospace Exposition, 2010
Future wind tunnel test requirements are very difficult to forecast due to the uncertainties of anticipating future direction of national needs, budgetary pressures, military requirements, and evolving technology. Wind tunnel testing is anticipated to continue to provide a very significant percentage of development and validation data needed in pursuit

Wind-Tunnel Tests of an Aircraft Turret Model
Journal of Aircraft, 1999The drag of a half-scale aircraft laser turret is investigated in a low-speed wind tunnel. Forces, moments, and pressures are recorded fortheturretand aft-mounted fairings and splitter plates. Oil traces and tufts indicatethat the e ow is characterized by dominant vortices shedding from the top of the turret and a large trailing wake of vorticity ...

Wind-tunnel tests of a tilt-rotor aircraft
The Aeronautical Journal, 2011AbstractA wide aerodynamic test campaign has been carried out on the tiltrotor aircraft ERICA at the Large Wind Tunnel of Politecnico di Milano by means of a modular 1:8 scale model in order to produce a dataset necessary to better understand the aerodynamic behaviour of the aircraft and to state its definitive design.The target of the tests was the ...

Modular asymmetric parachute for wind tunnel testing
Journal of Aircraft, 1981The construction of a series of asymmetrical wind tunnel model parachutes designed to a modular concept is described. The static force, inflation force, and dynamic force and motion time history wind tunnel testing of up to 123 different configurations is discussed.

Uncertainty Identification of Supersonic Wind-Tunnel Testing
Journal of Aircraft, 2010In this study, a methodology for the identification of uncertainty of supersonic wind tunnel testing is developed. Instead of conventional multi-tunnel testing, multi-position testing is performed across the characteristic net of supersonic flow. From the variations in aerodynamic coefficients in body axes, the uncertainty caused by flow quality is ...
