Book Description
The document covers observations of transitions of the hypersonic boundary layer on a cone at M = 10. Transition independent of the unit Reynolds number was obtained. Blunt cone transition with a wide range of nose radii was examined. It was found possible to correlate transition on different blunt cones using a new bluntness parameter. (Author).

Experimental Study of Stability and Transition of Hypersonic Boundary Layer Around Blunted Cone
Author: Antoloy Alexandrovich Maslov
Publisher:
ISBN:
Category : Aerodynamics, Hypersonic
Languages : en
Pages : 69
Book Description
The objective of this project is to basic research of stability and transition of hypersonic boundary layer around blunted cone. Next results is obtained: -experimental data on the position of the laminar-turbulent transition in the boundary layer of a cone with different nose bluntness for Mach 6; -experimental data on the characteristics of natural disturbances in the hypersonic boundary layer of a blunted cone for Mach 6; -experimental data on the evolution of artificial disturbances, excited in the hypersonic boundary layer on a blunted cone for Mach 6. Acquired experimental data could be used for validation of numerical techniques. Using of obtained data will help to more accurate prediction of laminar-turbulent transition location and thereby heat fluxes on hypersonic vehicles.

The Effect of Pressure Gradients on Transition Zone Length in Hypersonic Boundary Layers
Author: Roger L. Kimmel
Publisher:
ISBN:
Category : Aerodynamics, Hypersonic
Languages : en
Pages : 46
Book Description
Boundary layer transition was measured in zero, favorable, and adverse pressure gradients at Mach 8 using heat transfer. Models consisted of 7 degrees half angle forecones 0.4826 m long, followed by flared or ogive aft bodies 0.5334 m long. The flares and ogives produced constant pressure gradients. For the cases examined, favorable pressure gradients delay transition and adverse pressure gradients promote transition, but transition zone lengths are shorter in favorable pressure gradient. Results of the effect of adverse pressure gradient on transition zone lengths were inconclusive.
