This book was released on 1970 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of force tests was conducted on unpowered, high-speed ground-vehicle model configurations to provide information on shapes of this type very near the ground. Of particular interest were the crosswind effects on the aerodynamic forces and moments of the six models tested. These tests were conducted over the moving-belt ground plane in the 17-foot (5.18-m) test section of the Langley 300-MPH 7-by 10-foot tunnel at free-stream dynamic pressure values of 10 lb/ft2 (478.8 N/m2). The results indicate that the half-circle configuration is desirable because of the low rolling moments it experienced; however, it did have higher lift values than the other configurations and, from a utility standpoint, could be impractical. The half-circle configurations with extended sides may make good compromise configurations. All the ground-simulation techniques employed -moving ground belt, fixed ground belt, and image model -gave reasonable representations of the overall aerodynamic trends.

Grunwald and published by . This book was released on 1970 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Air-cushion models employing peripheral jet and plenum cushions of circular, rectangular, and side-by-side planforms were tested in hovering and at forward speed in the 17-foot (5.18-meter) test section of the Langley 300-MPH 7- by 10-foot tunnel. The principal purpose of these tests was to study the characteristics of air cushions when freestream dynamic pressure exceeded air-cushion pressure. Also examined were the hovering performance and the effects of moving ground belt, crosswind, height, and angle of attack. For the configurations tested, there was no significant loss in cushion performance when free-stream dynamic pressure exceeded cushion pressure.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains papers presented at the International conference “The Aerodynamics of Heavy Vehicles III: Trucks, Buses and Trains” held in Potsdam, Germany, September 12-17, 2010 by Engineering Conferences International (ECI). Leading scientists and engineers from industry, universities and research laboratories, including truck and high-speed train manufacturers and operators were brought together to discuss computer simulation and experimental techniques to be applied for the design of more efficient trucks, buses and high-speed trains in the future. This conference was the third in the series after Monterey-Pacific Groove in 2002 and Lake Tahoe in 2007.The presentations address different aspects of train aerodynamics (cross wind effects, underbody flow, tunnel aerodynamics and aeroacoustics, experimental techniques), truck aerodynamics (drag reduction, flow control, experimental and computational techniques) as well as computational fluid dynamics and bluff body, wake and jet flows.
