Abstract

Experiments were carried out on a rudimentary four-wheel landing gear arrangement to understand the flow physics of this configuration. Measurements carried out included oil flow visualization, steady and unsteady surface pressures and steady loads at a Reynolds number based on wheel diameter of 1 x 106. The surface visualization demonstrated the significantly asymmetric behavior of the flow on both the front and back wheel. The data show that the truck and strut are dominant contributors to the total drag. The data presented here, provides a comprehensive picture of the surface flow features both quantitatively and qualitatively of a rudimentary landing gear and will be supplemented by off-body flow measurements in subsequent phases.
