A Short History of Marine Propellers

In the late 19th century, the race to create the perfect marine propeller was on the rise. Two main propulsion theories existed. One, the momentum theory – a theory describing a mathematical model of an ideal actuator disk – the other, the blade element theory (BET). The BET broke down the propeller into smaller parts to determine the force on them. Later, the two theories combined to create the blade element momentum theory, alleviating some difficulties in determining the factors and calculations of the BET. This formed the modern marine propeller calculation.
