' ':-- "- ~ J;~00 Summary.--The inefficient pressure recovery of present day supersoific wind tunnels, which leads to high costs of plant installation and operation, is discussed and methods of improvement suggested. In particular, the diffuser system, where most of the losses occur

Summary.--This report describes a frost-point hygrometer suitable for measuring the water-vapour content of the air in supersonic wind tunnels at any stagnation pressure within their present range of operatiom It uses CO2 as a coolant and is economical in construction and operation. 1. Introduction

I don’t know why I was chosen to make this talk—the men who know all about it are sitting here in case you want to ask any questions. They are A.W. Young and L.L. Monroe who wrote the Design and Performance Specifications [reference 1] and carried through the design. The Altitude Wind Tunnel

With the goal of studying Natural Laminar Flow (NLF) wings for future ‘green’ transport aircraft, the aim of the European Research Project TELFONA is to develop and demonstrate the possibility of testing full aircraft models with NLF wings at large Reynolds numbers in the cryogenic Wind Tunnel ETW

We have developed a new technique for evaluating cache coherent, shared-memory computers. The Wisconsin Wind Tunnel (WWT) runs a parallel sharedmemory program on a parallel computer (CM-5) and uses execution-driven, distributed, discrete-event simulation to accurately calculate program execution

Abstract: The regulation of a wind tunnel system using minimum control effort is considered. A theory enabling input–output models to be employed in the design process is outlined. The procedure is applied to the regulation of the airspeed within the tunnel working section enabling turbulent

flight experiment (ISAFE). The most recent ISAFE results' from STS-103, consisted of port side images, at hypersonic conditions, of the surface features that result from the strake vortex scrubbing along the side of the vehicle. The wind tunnel results' were obtained with the phoslhor
