Drag Reduction by Off-Body Energy Deposition

Active Technology Project

Project Introduction

Drag Reduction by Off-Body Energy Deposition
What are the key technical challenges? Implementation of non-equilibrium thermochemistry; Accurate energy balance; Dynamic impulse measurements at Mach 2 What is your approach/research plan? Combined CFD/Experimental investigation; Bench laser deposition data (incident, transmitted power, blast wave expansion rate); Impulse for single energy pulses using model spring-mass system dynamic response. What are the innovative aspects (how is this different than what others are doing in industry, academia government)? Non-equilibrium thermochemistry rather than ideal gas; Full energy accounting for laser energy deposition; Wind tunnel model impulse drag measurements rather than steady state (reduces laser/experimental costs/ and risks) More »
