Available in PDF, EPUB and Kindle. Book excerpt: A system concept for the incorporation of magnetic projectile guidance into aeroballistic ranges is presented and analyzed. Basis of the concept is motion-induced, electrodynamic interaction between conductive material in the projectile's forebody and a guideway of field source currents. Theory is developed for deployment of the currents such that on the one hand the forebody will be repulsed toward the guideway centerline as a function of error in lateral position whereas, on the other hand, there will be damping of resulting lateral motion. Expressions are subsequently derived which interrelate the magnitude of forces to the magnitude of guideway currents, and generalized equations of motion for the projectile are developed with both electrodynamic and aerodynamic forces being considered. A design example is included wherein the developed theory is correlated to an existing aeroballistic range (AEDC/VKF Range G) where projectiles with base diameters on the order of 0.05 m are launched at velocities of 4,000 to 6,000 m/sec. Results are gratifying in that computed flight paths for varying conditions indicate that stable guided flight can be achieved with guideway currents of reasonable magnitude. Practical means of providing these are discussed. (Author).

This book was released on 1977 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two types of experiments have been conducted to determine adequacy of theory relative to a previously reported system concept for the incorporation of magnetic projectile guidance into aeroballistic ranges. The concept is based on motion-induced electrodynamic interactions between conductive material in the forebody of projectiles and a guideway of field source currents. By using a rotating machinery apparatus, one set of experiments was conducted to simulate the interaction between a projectile forebody and the guideway currents to the extent that predicted positional forces could be measured. These forces which are intended to act toward the guideway axis as a function of lateral forebody position were in agreement with theory. Through use of a pendulum apparatus, another set of experiments was conducted to simulate interactions to the extent that predicted damping forces as needed for retardation of lateral forebody motion could be measured. Again, the results were in agreement with theoretical predictions. (Author).

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.
