Application of Coandă Jet for Generating Lift of Micro Air Vehicles - Preliminary Design Considerations

Abstract:

Article Preview

Coandă effect, which has been widely utilized in many engineering applications for circulation control, is here reviewed for the design of Coandă Micro-Air-Vehicles (MAVs). Based on the review, a basic spherical configuration is analyzed to obtain the relationship between relevant parameters to the lift that can be produced based on fundamental principles. The results can be used for preliminary design purposes and are discussed in view of existing literature.
