DREA'S PROPELLER DESIGN AND ANALYSIS EXPERIENCE

The program of marine vehicle R&D at Defence Research Establishment Atlantic, Canada, includes studies of propeller performance and propeller-hull interaction. Experience to date justifies the use of lifting line, two-dimensional section, and lifting surface codes for propeller design or analysis against propulsion criteria. Integral boundary layer methods are adequate for generating propeller inflow conditions in preliminary design or analysis studies of destroyer-like hull geometries. When sheet or bubble cavitation performance is important, lifting surface propeller codes are often found inadequate due to deficiencies in blade thickness modelling, particularly near the blade root. Surface singularity panel codes offer greater promise for cavitation performance prediction than does incremental improvement of lifting surface codes. Considerable research is still required on modelling other types of cavitation and on the physics of cavitation noise. Detailed numerical studies of propeller-hull interaction, particularly as it influences noise, will require the development of Navier-Stokes flow solvers.
