Numerical Study of Wall Ventilation in a Transonic Wind Tunnel
Journal of Aerospace Technology and Management, 2015 Transonic wind tunnels (TWT) are sophisticated tools for the investigations of flows with Mach numbers of order one. The most characteristic feature of a facility such as this is, for sure, the openings in the walls of the test section.

Automatic Attitude Setting of a Wind Tunnel Model in a Transonic Wind Tunnel
Automatic Attitude Setting of a Wind Tunnel Model in a Transonic Wind TunnelA description of an improved automatic attitude setting system, of a wind tunnel model in a 2m×2m transonic wind tunnel is presented. The purpose of this improvement is to save on manpower, and shorten the access time for setting from one testing condition to another. An 8K words mini-computer is employed, to control the electirically powered mechanism
