A propeller (more explicitly named as blade propeller or screw propeller) is a propulsion device that creates relative motion by forcing the environmental fluid axially backwards, by means of azimuthally-rotating blades mounted in a shaft that is driven by an engine (reciprocating, rotational, turbine, electrical...).
Complete course lecture notes on Hydrofoils and Propellers by Justin E. Kerwin.
Lecture notes were originally developed by Jack L. Kerrebrock and subsequently adapted by Manuel Martinez-Sanchez. This section provides the schedule of lecture topics and includes select lecture notes for the course excluding lessons on aircraft propulsion and jet engine rotordynamics.
Find Ct based on your chosen propeller area. Choose the number of blades. Know Va, D, N. Use chart: Start with Absolute advance coefficient = Va/ (π n = J/π) Follow up diagonal line until you hit the horizontal line that corresponds to your number of blades.
