Abstract
The basic design features of ventilated wall transonic test-sections for blowdown wind tunnels are reviewed with respect to the flow quality requirements and wall interferences characteristics. The influence of such basic factors as the geometry of slotted and perforated walls, nozzle divergence and plenum dimensions etc. are noted. The methods of mach number control and stabilisation are discussed. Preliminary results of experiments at present being conducted with a pilot transonic test-section fitted to a blowdown wind tunnel are used to illustrate some of the important aspects of the design problem.
