Evaluation of Two Types of Facilities to Fulfill the Need for High Reynolds Number Transonic Testing,
Abstract
The Navy's need for high Reynolds number transonic testing is reviewed and some specific problem areas in weapon and aircraft design are cited. The abilities of currently available wind tunnels in the United States to meet those needs are assessed and the Ludwieg tube wind tunnel at NASA Marshall is evaluated. The theory of the Ludwieg tube is discussed and tables and charts of the parameters are presented. A second option to meet the high Reynolds number testing requirements is examined in the theory and design of a conventional blowdown tunnel. The costs of the two types of facilities are compared for Navy weapons and flight vehicles at subsonic, transonic and low supersonic speeds.
