Background National studies coordinated under the auspices of AR&DB in the late eighties
identified a strong need for a low speed wind tunnel in India to provide Indian Industry with adequate support in experimental aerodynamics for effective development work. Thus, a National Wind Tunnel Facility Project (NWTF-P) was initiated.
NWTF was conceived as an autonomous activity at IIT Kanpur in the academic environment, with the objective to construct, operate, maintain and further develop the wind tunnel facility as a Users’ Facility.
Further, due to funding constraints it was decided to implement the project in two phases as follows:
Phase I Tunnel circuit, fan, motor, and drive system Model support mechanism, turntables, and instrumentation
Phase II Test section parking hall and tunnel control room Instrumentation and calibration rooms Model design, inspection, integration rooms and model shop Wind tunnel offices, conference room, model display room
