This work presents a novel dynamic inflow modeling approach for single- and multirotor systems. The proposed model is derived from first principles using a parametrisation that guarantees accurate results at steady-state. In an effort to simplify and unite previous works in the field, it is shown how two important works from the dynamic inflow modeling literature can be recreated using the present framework. The utility of the model is further illustrated through analysis and comparisons to well-established theories and empirical results in both steady-state and dynamic scenarios. Overall, the aim is to simplify and unite dynamic inflow models.
