WebAug 1, 2024 · This trend was partially explained based on evaluating the forebody wake flow properties [9, 96, 101, 102]. The momentum defect of the forebody wake was characterized by the difference between the dynamic pressure in the free stream and that in the centerline of the wake, which could lead to a decrease in the parachute drag [9, 96, … http://toc.proceedings.com/35231webtoc.pdf

WebAn experiment was conducted to evaluate approximate analytical methods for predicting the reduction in parachute drag due to forebody wake effects. The drag of a 20/sup 0/ conical ribbon parachute was measured at several axial stations behind an ogive-cylinder forebody with and without fins. The same parachute was tested in undisturbed flow (where wake … Webbehaviour, wake effect, stability and various aerodynamic forces.
