Abstract:

The use of the torque converter principle in marine propulsion transmission was investigated. This included scaling an existing design by laws of similitude with two unit compounding for high speed ratio, torque converter compounded with gearing, and single unit torque converter design with axial flow components for high speed ratio. CONCLUSIONS 1 no existing single unit torque converter design will meet the reduction ratio requirements of 15 or 25 to 1 at practical efficiency levels 2 to meet required speed ratio, it is necessary to compound two units of existing design, compound one torque converter unit with single gear reduction, and design a new torque converter unit with pump and turbine elements adapted to high speed ratio and 3 high speed ratio torque converter designs involve high flow, low head, and high relative flow velocities, leading to high fluid friction losses and tendency to cavitate.
