DESIGN CONSIDERATIONS FOR THE CONTROL AND PERFORMANCE

OPTIMIZATION OF A VTOL UAV USING THE COANDA EFFECT

 

The Coanda effect is a phenomenon of fluid dynamics whereby a jet exhibits a strong tendency to become attached to, and flow around, a nearby surface. Vertical Takeoff and Landing (VTOL) Unmanned Aerial Vehicles (UAVs) utilizing the Coanda effect for lift generation have a number of potential benefits, including: (a) the creation of a large aerodynamically-neutral payload/systems bays, (b) a high payload-carrying ability for its size, and (c) the use of an enclosed rotor, enabling it to withstand contact with its surroundings.

 

Coanda effect UAVs have undergone some study, but remain a largely under-investigated and certainly un-optimized VTOL configuration. This proposed research aims to address this by:

  • Developing a physics-based model for the aircraft’s flight dynamics
  • Developing a robust flight controller for hover and low-speed flight
  • Developing analytical and numerical methods to predict performance characteristics
  • Incorporating this knowledge into an optimization strategy for maximizing the aircraft’s potential as a safer VTOL UAV for use in urban and otherwise challenging environments
  • Validating all of the above works with experimental data gained from static and flight tests
