Design and testing of a ground effect drone
Ground Effect (GE) Vehicles, otherwise known as WIGs (Wing in Ground-Effect Vehicles), are aircraft designed specifically to cruise at low chord-normalised ground clearances of less than 1 to reap the aerodynamic benefits of ground effect. However, practical concerns in GE vehicle design limit t...

Ground Effect (GE) Vehicles, otherwise known as WIGs (Wing in Ground-Effect Vehicles),
are aircraft designed specifically to cruise at low chord-normalised ground clearances of less than
1 to reap the aerodynamic benefits of ground effect. However, practical concerns in GE vehicle
design limit the extent to which the potential of ground effect can be realised. The objective of
this FYP is to investigate the challenges in developing a GE vehicle for operation in extreme
ground effect, which is observed for normalised ground clearances less than 0.1. To this end, a
small-scale GE drone was sized using XFLR5 and built to a low take-off weight of 600g using a
XPS foam fuselage and monocoque foam-core wings. Aerodynamic analyses of the GE drone
were performed using wind tunnel testing and XFLR5. Obtained results show the alignment of lift
predictions using XFLR5 with experimental data. Experimental results also align with all existing
theoretical models in showing the increasing rate of lift increments when ground clearance is
reduced. A potential 72% improvement in maximum lift to drag ratio was observed for the current
GE drone when chord-normalised ground clearance was decreased from 1.4 to 0.6, and even
greater improvements can be expected for GE drones designed to cruise in extreme ground effect.
Flight tests were also performed but were inconclusive due to difficulties in conducting proper
tests. In conclusion, this study found the design requirements for a water take-off to be a major
challenge towards the development of an extreme ground effect drone as it is mutually
incompatible with design requirements for a low operating ground clearance. Therefore, future
GE drone designs may consider taking off from ground or vertically instead. |
