A theory for the prediction of dynamic inflow is published
Thursday, December 31, 1981
Before the theory for dynamic inflow was developed it had proved very difficult to predict the response of a rotor during dynamic conditions.
The initial work in this area, published by Pitt and Peters, was a very important step for rotor stability analyses and the development of real time simulation models for rotor behavior. The reference for the paper is provided below,
