Abstract

The study of Handling Qualities (HQ) constitutes an integral part of the air vehicle design process, ensuring safety and flyability. Nevertheless, traditional HQ sizing methods derived for conventional aircraft configurations provide decreasing insight on modern, unconventional, flight-control-augmented vehicles, mainly due to the lack of related operational experience. In this article, a new HQ sizing methodology is proposed aiming at a more vehicle-agnostic approach than existent techniques. Based on the concept of state-space polytopes, the method provides a means for visualizing the HQ requirements and comparing them to the vehicle's control authority. The polytopic representation serves to compact the dynamic HQ requirements down to a limited number of quasi-equilibrium calculations and allows for the analytic derivation of “HQ gradients” with respect to the vehicle's design features; simultaneously, non-linear control saturation aspects are accounted for. Test cases on two vehicles with complex, yet very different HQ characteristics - a Blended-Wing-Body (BWB) aircraft and an electric Vertical Take Off and Landing (eVTOL) vehicle - are selected to demonstrate the technique's effectiveness and potential application domain.
