CFD Modeling of US Army UAVs using NASA's OVERFLOW CFD Code

摘要

Since 2010, the United States Army Aviation & Missile Research, Development, & Engineering Center (AMRDEC) has supported Project Manager Unmanned Aircraft Systems (PM UAS) programs of record (POR), namely the Shadow RQ-7B & RQ-7B IE (short wing and Rewing variants respectively), RQ-11 Raven, and MQ-1C Gray Eagle, with high fidelity aerodynamics predictions. These efforts have leveraged the National Aeronautics and Space Administration (NASA) OVERFLOW computational fluid dynamics (CFD) code to support performance predictions and payload integration studies.
