Hydroacoustic Testing of a NACA-66 (MOD) Hydrofoil in the GALCIT High Speed Water Tunnel

Abstract
The work described in this report represents a primarily exploratory effort to assess the feasibility of performing accurate hydroacoustic measurements at high signal-to-noise ratios, in the GALCIT High Speed Water Tunnel (HSWT), hereafter referred to as the Tunnel, to characterize the hydroacoustic environment in the HSWT 2-D test section, and to complement the force and flow visualization measurements that were performed using the two-dimensional, NACA 66 (MOD) hydrofoil in the recent past. See Baloga (1982), Dimotakis et al. (1988), Shen & Dimotakis 1989a, and Shen &. Dimotakis 1989b. This work was also a sequel to earlier hydroacoustic measurements that were performed by S. Barker (1974, 1975, 1976) in the same facility.
