Ballistic Research Laboratories' Wind Tunnel Compressor Plant


Book Description

The wind tunnels branch of the Exterior Ballistics Laboratory (EBL), Ballistic Research Laboratories (BRL), Aberdeen Proving Ground, Maryland operates three supersonic wind tunnels and one hypersonic wind tunnel. The supersonic wind tunnels use flexible plate nozzles and may be operated up to a Mach Number of 5.5, whereas the hypersonic tunnel uses axisymmetric nozzles for operation at Mach Numbers 6, 7.5 and 9.2. Air is furnished to the tunnels by centrifugal compressors operating in a closed loop system. There are two compressor plants. (Author).




Ballistics


Book Description

With new chapters, homework problems, case studies, figures, and examples, Ballistics: Theory and Design of Guns and Ammunition, Third Edition encourages superior design and innovative applications in the field of ballistics. It examines the analytical and computational tools for predicting a weapon’s behavior in terms of pressure, stress, and velocity, demonstrating their applications in ammunition and weapons design. New coverage in the Third Edition includes gas-powered guns, and naval ordinance. With its thorough coverage of interior, exterior and terminal ballistics, this new edition continues to be the standard resource for those studying the technology of guns and ammunition.
