Abstract:
A numerical estimation method is here applied for axisymmetric hulls. They present increasing fineness ratio from 7.0 (Series 58 model n. 4164), 8.6 (DARPA SUBOFF), 10.5 and 12.0 (general hullform). The hulls were presented in the works of, respectively, Landweber and Gertler 1950, Groves et al. 1989 and Heberley 2011. Well established formulations were applied aiming to estimate lift forces and yawing moment. The formulations are from Allen and Perkins (1951), Safel el al. (1971), Finck (1978) and Granlund (2009). For the 58 Series and DARPA SUBOFF hulls, experimental results are presented. The objective of this work is to present numerical and experimental results intended to be helpful in the early stages of submersible design, avoiding computation costs of CFD codes.
