PAV/eVTOL – How Do You Analyse Transition

This is the second paper in the series of focusing on modelling and analysis challenges when developing PAV/eVTOL aircraft.

This paper focuses on how the j2 Universal Tool-Kit is applied to developing the model such that all the aspects of Tilt Rotors can be incorporated quickly and easily into the model for transition analysis. Transition from hover/vertical flight into forwards flight is a critical phase in the flight of PAV/eVTOL platforms. This can be difficult to model as there are a lot of variables requiring the blending of controls and flying techniques. This paper provides an outline of work that has been carried out using the j2 Universal Tool-Kit on a tilt rotor UAV. This work was originally performed for a customer but has been reproduced here using an example aircraft. The data and model are representative as is the work process used to demonstrate what is capable with the j2 Universal Tool-Kit. An important advantage when applying j2 Universal Tool-Kit into PAV/eVTOL development is that the user can accommodate different controls be it change in aircraft attitude, change in engine orientation, or classical control surfaces without the need to write any code or develop scripts.
