Plasma Flow Control for Drag Reduction, Phase II

Completed Technology Project

Project Introduction

This Phase II SBIR project deals with advancing the design, development, and testing of an innovative drag reduction concept named ?Smart Longitudinal Instability Prevention via Plasma Surface? using a new revolutionary plasma actuator technology developed at the University of Notre Dame (UND). During Phase I, Innovative Technology Applications Company (ITAC), LLC and researchers from UND developed and demonstrated drag reduction of more than 65% in turbulent boundary layers using the SLIPPS approach. This approach intervenes in the Streak Transient Growth Instability mechanism which is a dominant mechanism in the production of drag in turbulent boundary layer flows. In Phase II, we will investigate and test the use of SLIPPS concept at both higher Mach number and Reynolds number flows, as well as build an improved understanding of the physics in order to make even further efficiency gains possible. Phase III will advance the TRL to a level suitable for flight tests and integration into production systems. More »
