Blade element theory
|
|
Blade element theory is a mathematical process originally designed in the nineteenth century to determine the behaviour of propellers. It involves breaking an airfoil down into several small parts then determining the forces on them. These forces are then converted into accelerations, which can be integrated into velocities and positions.
