![]() ![]() Vortex or radial components of flow induced by angular acceleration due to the rotation of the propeller. The theory does not include secondary effects such as 3-D flow velocities induced on the propeller by the shed tip The resulting values of section thrust and torque can be summed to predict the overall performance of the propeller. This produces a set of non-linear equations that can be solved by iteration for each blade section. ![]() At the same time a balance of axial and angular momentum is applied. In this method the propeller is divided into a number of independent sections along the length.Īt each section a force balance is applied involving 2D section lift and drag with the thrust and torque producedīy the section. A relatively simple method of predicting the performance of a propeller (as well as fans or windmills) ![]()
