W.E.W. Petter hired Wing Commander R.P. Beamont as chief test pilot—an outsider with extensive combat experience—to ensure ...

Shock wave and turbulent boundary layer interactions are phenomena encountered in high-speed flows, where abrupt pressure changes associated with shock waves impinge upon the viscous layer of fluid ...

A typical challenge for re-entry vehicles during flight is an effective control of hypersonic transition and the laminar/turbulent state of the boundary layer. The state of the boundary layer is of ...

In order to determine the best way to simulate a road in the full-scale climatic wind tunnel of the Voklswagenwerk AG, a series of comparative tests between road and tunnel have been carried out. In ...

Improved observations of the atmospheric boundary layer (BL) and its interactions with the ocean, land, and ice surfaces have great potential to advance science on a number of fronts, from improving ...

SAE Transactions, Vol. 96, Section 6: AEROSPACE (1987), pp. 1279-1291 (13 pages) Correlations for transition from laminar to turbulent flow on 45° and 60° swept cylinders based on data obtained in the ...

Newly released photos of the B-21 Raider reveal its close design lineage to the YF-23 "Grey Ghost," showcasing features like recessed engine intakes, boundary layer control, and advanced stealth ...

Plasma technology based on Dielectric Barrier Discharge (DBD) has been widely demonstrated to be a novel active flow control method. In order to make the plasma flow control technology more practical, ...
