The overall  shape of the LTAV is similar to a missile due to dynamic stability  requirements and axial symmetry conditions. High altitude gusts  and high magnitude wind conditions often put a stable LTAV into  an unstable environment. Hartfield will also look at reducing axial  drag alongside dynamic stability. His group will conduct analysis  of surface pressure distributions towards flow separations in the  high turbulent regimes under study for high altitude applications.  They will explore the development of a more advanced flow  separation model based on adverse pressure gradients.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Operating lighter-than-air vehicles (LTAVs) in high altitudes can cause aerodynamic problems from turbulent flow environments that generate gusty and high magnitude winds.
