Coanda Effect Test Bench (CoETB) — Design enhancement of the CoandaJLT craft

This paper presents the improved design of a Coanda Effect Test Bench (CoETB) and its experimental data. The CoETB is primarily setup to investigate the authors' hypothesis that a steerable Coanda effect can be used for flight directional control. The design is currently based on the Unmanned Aerial Vehicle (U.A.V) manufactured by GFS Projects Limited or known as the GFS-UAV. The CoETB experiment results showed variation of lift resulted by varying the Coanda curve profile angle. The authors presents the works in setting up the CoETB and its experimental results is discussed in this paper.
