  1. Implementation of Active Flow Control using Microjets on an RC Aircraft Phil Kreth Hussein Nabulsi Dan Drake Matt Tubtim Faculty Advisor: Dr. Farrukh Alvi Sponsor: Dr. Gregg Abate (Eglin AFB)

  2. Presentation Outline Background and Scope Needs Assessment Detailed Design Wind Tunnel Testing Spring Proposal Budget Analysis

  3. Background Flow separated ~16° AOA Reattached flow – 10 psig @ microjets Flow separation

  4. Needs Assessment Implement microjets on RC plane Run time should be 30 secs or more Remotely activate each wing Delay stall Budget = $1,50000
