FLIGHT STABILITY OF A FLYING WING MADE FROM SOLID FOAM

Maksym Petrenko, Peter Gašparovič

Abstract


This paper presents an investigation into the static and dynamic flight stability of a tailless flying wing made from solid foam (EPP). In the absence of traditional tail surfaces, the aerodynamic design uses a reflexed airfoil along with a carefully positioned center of gravity for maintaining longitudinal stability. The research integrates numerical simulations, wind tunnel tests, and actual flight trials to assess the model’s performance under various flight conditions. Although the foam structure allows for cost-effective prototyping, it introduces a level of structural flexibility that can impact measurement accuracy and stability. The findings show that a well-constructed flying wing provides sufficient stability; however, materials such as EEP are too flexible for static testing in the wind tunnel, although they are good in dynamic flight.
