Join us for a two-day comprehensive workshop on marine propeller design and analysis!

Instructor: Donald MacPherson, Technical Director HydroComp

HydroComp’s Propeller Bootcamp is an intensive professional development workshop on marine propeller design and analysis. The course was developed to fill demand from propeller builders and distributors, naval architects and shipbuilders, ship operators, and engine and transmission companies.

The two-day Bootcamp will have four principal topic groups that follow the common “life-cycle” of a marine propeller:
1. principles of propulsion and propeller sizing,
2. fundamentals of detail propeller design,
3. propeller CAD, and
4. propeller analysis and troubleshooting.
This educational seminar also includes is a section on detail propeller design. This section will discuss the calculations and design strategies used by propeller specialists to develop optimized wake-adapted propeller designs. The section will use HydroComp’s newest product – PropElements – to demonstrate key concepts in detail propeller design.

What is the curriculum for the course?

The curriculum is comprehensive, but notable topics will include:

  • Principles of propulsion and propeller performance
  • Propeller selection and propeller sizing
  • Considerations for engine/transmission matching
  • Early stage design for a coastal passenger vessel
  • Introduction to propeller design methods
  • Techniques of detail propeller design
  • Wake-adapted propeller design
  • Strength analysis, KTKQ performance
  • Propeller drawings, offset reports, and CAD models
  • Classification and propeller blade thickness compliance
  • Inspection and scan data for propellers
Typical morning session 8:30a-12:00n 

Principles of marine propulsion
This is where marine professionals can reacquaint themselves with the principles of marine propulsion for inboard propellers on all boat types, from large work boats to smaller “go-fast” boats. Includes: Propulsion system relationships; Propeller performance; Cavitation.

Initial propeller sizing
This topic discusses the successful sizing of a propeller’s principal parameters (diameter, pitch, blades, blade area), and proper matching to engine and gear ratio. Includes: Selecting the proper propeller style; Considerations of engine performance; Achieving a successful propeller sizing match to the boat, engine and transmission. Featuring: NavCad, PropExpert.

Case study: Early stage sizing
Speed prediction; engine selection; sizing propeller and gear. (A common case study – a coastal passenger vessel – will be used across all four topic groups.)

Included lunch 12:00n-1:00p

Typical afternoon session 1:00p-5:00p 

Detail propeller design
The theory and techniques of detail propeller design are presented in this session. Moving from general characteristics to the specific, we will investigate the optimized design of radial distributions of pitch, camber, chord, thickness and skew. Includes: Introduction to propeller design methods; Wake-adapted design; Definition of suitable design condition; Strength analysis; KT-KQ curves. Featuring: PropElements

Propeller geometry and CAD
We will investigate the path from design to manufacture. Widely-used propeller design documents form the basis of an architecture of geometry, which then extends from 2D to 3D, and integration with CAD/CAM. Includes: Standard design drawing; Tables of offsets; Hub and tip details; Principal characteristics; Classification thickness reports; Successful integration with CAD/CAM; Using inspection or scan data. Featuring: PropCad, Rhino3D.

Case study: Detail design and CAD
Determining the design point; preparation of the detail design; propeller drawings; classification society thickness calculation; 3D CAD models.


About the trainer

The NavCad “Best Practices” Training Course is conducted by Donald MacPherson, HydroComp’s Technical Director with support from other HydroComp staff. A frequent speaker to conferences, technical societies and trade groups, Mr. MacPherson is a graduate of Webb Institute and author of many noted journal articles and technical papers on ship propulsion and propeller performance. He is also the Instructor of Naval Architecture in the Ocean Engineering Department of the University of New Hampshire.

Who should attend the Training Course?

Workshop is suitable for anyone involved in the design, construction, selection, operation, or repair of propellers. In today’s competitive business environment where it is all about “green” efficiency, the Workshop is essential for:

  • propeller builders and distributors,
  • naval architects and shipbuilders,
  • ship operators, and
  • engine and transmission companies.

Do I need HydroComp software to attend?

No, the Propeller Workshop is not intended to be software training. However, we will be using various HydroComp software to demonstrate concepts, principles, and techniques. Users are welcome to bring their software on a laptop to follow along, but this is not required.
