Implementation of Active Flow Control using Microjets on an RC Aircraft

This project explores the implementation of active flow control techniques utilizing microjets on a Remote Controlled (RC) aircraft. We assess the needs for mitigating flow separation at angles of attack around 16°, allowing for reattached flow at 10 psig. The design includes an air supply system, effective airframe modifications, and the use of servo-mounted cameras for data measurement and validation. Wind tunnel testing is planned to optimize system effectiveness. The presentation outlines our detailed design, testing methodologies, budget considerations, and anticipated outcomes.
