    Abstract

    This document details the Augmentation of the 1.2m x l.2m13; Low speed Dynamic Test Wind Tunnel at Flight Mechanics amp; Controls Division. The Tunnel designed in 1982 was originally capable of 32 m/s fixed speed. With sponsorship of AR amp; DB, the tunnel volocity has been enhanced to variable speed capability of 20-60 m/s using a 175 kw DC motor and an inlet Guide Vane system capable of 1:1:8 ratio speed control. The latter provides 5 m/s/s flow acceleration capability. This ARDB project has been completed in 15 months time
