Abstract:
Flying boat design is the topic that the Aerospace
Engineering Department has concerned and studied since
2004. Previous students and researchers had researched
and analysed about the characteristics of various
configurations with the purpose of making an effective
model of flying boat or Wing in Ground effect Vehicle
(WIG). The model needs to adapt stability and safety
during operation, which sets the first stage for
commercialization in Vietnam market. Following previous
studies, we improve, analyse and design a small flying
boat with the new configuration which is similar to
hovercraft. This flying boat (or WIG) differs from the
traditional seaplane and simple WIG because it has an
additional air cushion system to provide supplemental
lift during take-off stage. In consequence, the
aerodynamic and hydrodynamic drag will be reduced so
that the required power from the engine is also reduced.
The research purpose is to analyse the hydro-
aerodynamic characteristics of the flying boat, then
comparing the difference between a traditional WIG and
the new one using air cushion system. In addition,
proving for the effectiveness when using an air cushion
system and calculating the required power is presented.
Finally, propulsion system is intergraded with suitable
engine for our Wing in Ground effect Vehicle.
