A summary of research efforts for last several years on fluid-dynamics and aero-optics of
hemisphere-on-cylinder turrets with flat and conformal windows is presented. The topology …

A mathematical model is presented for obtaining aero-optical wavefront of a light beam
passing through the forced supersonic mixing layer for adaptive-optic (AO) correction, which …

The effects of small-scale dissipative fluidic actuation on the evolution of large-and small-
scale motions in a turbulent shear layer downstream of a backward-facing step are …

TURRETS provide convenient housing for pointing and tracking laser beams from airborne
platforms. However, a turret creates a separated turbulent region in the flow, which, even at …

CURRENT research efforts are aimed at placing laser-based systems on aircraft to augment
their offensive and defensive capabilities. Unfortunately, propagating a beam through the …

Particle image velocimetry measurements have been conducted for a Mach 0.8 flow over a
wall-mounted hemisphere with a strongly separated wake. The shock foot was found to …

The mitigation of aero-optical aberrations in the wake of a surface-mounted turret comprised
of a hemisphere mounted on a matching cylindrical support is investigated in wind tunnel …

THE development of techniques for controlling separation has been driven, since its
inception, primarily by the need to accommodate the aerodynamic requirements of airplane …

TURRETS on airborne platforms are bluff-body protrusions that typically consist of a
spherical cap supported by a matching cylindrical base. They provide convenient housing …

TURBULENCE, random density fluctuations, and aero-optical distortion in the flow around a
turret can degrade the performance of a laser system housed within the turret. Laser light …
