Overview of Laminar Flow Control
The history of Laminar Flow Control (LFC) from the 1930s through the 1990s is reviewed and the current status of the technology is assessed. Early studies related to the natural laminar boundary-layer flow physics, manufacturing tolerances for laminar flow, and insect-contamination avoidance are discussed. Although most of this publication is about slot-, porous-, and perforated-suction LFC con...

متن کاملRetrofit Control: Localization of Controller Design and Implementation
In this paper, we propose a retrofit control method for stable network systems. The proposed approach is a decentralized control method that, rather than an entire system model, requires a model of the subsystem of interest for controller design. To design the retrofit controller, we use a novel approach based on hierarchical state-space expansion that generates a higherdimensional cascade real...
متن کاملToward Practical Laminar Flow Control— Remaining Challenges
Different laminar flow control strategies are reviewed for the various instability mechanisms and their applications over the different flight regimes are discussed. Success stories are told and unresolved problems are discussed. Over the years, the crossflow instability has been the primary challenge for laminar flow control. Favorable pressure gradients used to stabilize streamwise instabilit...
متن کاملSupersonic Laminar Flow Control on Swept Wings Using Distributed Roughness
The present work addresses a new technology development that can lead to drag reduction on supersonic aircraft by means of passive laminar flow control (LFC). Recent developments in the understanding of stability and transition in swept-wing flows in low-disturbance environments have offered the promise of controlling transition without the use of complicated systems. The principal control prob...
