In 2022, DEVCOM AvMC researchers applied HELIOS software to model the impact of recirculation on Navy aircraft performance for various static and dynamic flight conditions. HELIOS models the coupled aerodynamic and structural dynamics response of a vehicle using computational fluid dynamics codes for aerodynamics, computational structural dynamics to model structural bending, and vehicle trim software with multi-body dynamics to set the controls to achieve vehicle trim.
