| 摘要： | Bare hull resistance experiments were conducted for the HALSS trimaran, a Heavy Air Lift Seabasing Ship, as represented by Model 5651. During the first phase of testing, using just the HALSS center hull, two different bow sections, stem and bulbous bow, where tested. Further testing was completed with the HALSS center hull only, fitted with the best performing bow section and twin skegs, at two different drafts. The purpose of the second phase of testing was to investigate the resistance characteristics of the HALSS trimaran with a matrix of three longitudinal and three transverse side hull configurations. Also, further testing was completed to evaluate the resistance characteristics of three different center-hull-to-side- hull draft variations. These experiments were completed with HALSS center hull drafts of 11 meters and 12 meters and various shallower side hull drafts. Additionally, In order to design a propeller for this hull, the nominal wake at the starboard propeller plane was measured using Laser Doppler Velocimetry (LDV). / NOTE: Final rept.
