Building upon the prior research targeting the laminar breakdown mechanisms associated
with stationary crossflow instability over a swept-wing configuration, this paper investigates …

I. Introduction wept-wing laminar flow control (SWLFC) on transport aircraft has long been an
area of active academic and commercial research interest. Mature SWLFC could result in …

UBSTANTIAL reductions in the fuel burn of future aircraft have been targeted both in the US
1 and in Europe2 in order to lower the cost of air travel and alleviate the impact of aviation …

Maintaining the laminar flow on surfaces through active control is a significantly promising
technique for reducing fuel burn and alleviating environmental concerns in commercial …

Direct numerical simulation (DNS) is performed to examine laminar to turbulent transition
due to high-frequency secondary instability of stationary crossflow vortices in a subsonic …

Kin friction constitutes about 50 percent of the drag budget of a business jet or a long haul
transport aircraft, 1-3 as depicted in Fig. 1. Therefore, reduction in skin friction has the …

Previous flight research programs have sampled laminar flow control at a single control
point, usually a cruise condition. In the case of the presently discussed swept-wing-glove …

Transition analysis is performed for a swept wing at a Mach number of 0.75 and chord
Reynolds number of approximately 1.7× 10 7, with a focus on roughness-based crossflow …

VER the years, transition onset correlations based on linear stability theory have been quite
successful in predicting trends with respect to changes in aerodynamic design variables …

A high fidelity transition prediction methodology has been applied to a swept airfoil design at
a Mach number of 0.75 and chord Reynolds number of approximately 17 million, with the …
