to see the effect of changing the configurations of
the LE serration geometry on the flow behaviour of
the airfoil and to understand its relation with the
ATIN reduction.
Findings on how ATIN can be attenuated using
the LE serrations are valuable in many engineering
applications. One of them is the wind turbine. Wind
turbine noise is a subject of great importance as
people living nearby wind farms are reported to be
annoyed by the associated noise. It is very likely
that wind turbine noise will become more of a
problem due to the predicted increases in future
wind turbine size. This is because the growing
consumption and steady increase in price of non-
renewable sources has forced people to look for
alternative fuels that are available at an affordable
cost and can meet their growing demand for
energy. Also, many developed countries work hard
to reduce carbon dioxide emissions and the use
of fossil-based energy. Among the alternatives
available, one of them is wind energy. Therefore,
wind turbine noise is a subject of great importance
that requires further investigation in order to a
attain more peaceful and quieter living conditions.
#5. Enhancement of Unmanned Aerial
System operation through Utilisation of
existing Mobile Network
by Universiti Kuala Lumpur – Malaysian Institute
of Aviation Technology
The Unmanned Aerial System
(UAS) is an increasingly
important technology used
in various applications such
as agriculture, security and
utility maintenance due to
its capability to reach areas
not easily acces sible by
humans. For example, power
transmission lines are mostly
located in remote areas.
This infrastructure is difficult
to access for inspection or
maintenance purposes hence
the use of UAS is convenient
and impor tant. Currently,
an unmanned aerial vehicle
(UAV) can be flown by utilising a direct radio link
with a pilot at the ground station. This however
imposes a limitation on the range where the
UAV can fly because the radio link performance
degrades as the distance between the UAV and
the ground station increases.
This encourages a lot of research work to
enhance the range of UAV operation and by
association, the reliability of UAS. The existing
mobile network serves as a promising solution
that can remove the range limitation of UAS
operations. Through the 4G mobile network, high
bandwidth data-link provides virtually unlimited
range for UAS, hence increasing the operational
range for many applications utilising UAS. An
important element in this is the development
of a reliable communication link between the
UAS and the base station to which the UAS is
connected. This has been a challenging task
because the existing mobile network is primarily
designed to serve terrestrial users i.e. mobile
users located on the ground. In order to utilise
the existing mobile network to control UAS
operations, investigation on the feasibility of the
communication link between the UAS and base
stations is necessary. This is one of the many
research works undertaken by UAS Research
Lab in UniKL MIAT. This investigation involves
extensive field measurements in different
environments including urban, suburban and
rural areas.
