the hydrofoil, as a consequence of buoyant effect, hydrostatic pressure and cavitation effect. The characteristics of the
lift and drag coefficient will be discussed in this report.

Design of a Remote Control Vehicle

Supervisor: MA Lok Wang / MAE
Student: LIU Jun Bang Adrian / SENG Course: UROP1000, Summer

This research project aims to contribute to the IMechE HK Branch Greater China Design Competition 2018-2019 -- 8th
GCDC Energy Relay. A team will be led by Dr. Robin MA to represent HKUST and join the competition in March 2019. Our
team is required to design and manufacture 4 autonomous vehicles to run a relay race with different energy sources. At
this very early stage of the preparation for the competition, I am going to explore the rules and regulations of the
competition, feasibility of different energy sources, and possible designs in this progress report. It is hoped that this
study can be used as a reference for future works towards the competition.

Metallic 3D Printing with Ultrasonic Excitation

Supervisor: MA Lok Wang / MAE
Student: YAU Wing Ting / SENG Course: UROP1000, Summer

The aim of metallic 3D printing with Ultrasonic Excitation is to produce parts with higher mechanical properties (like
hardness, Young modulus) and reduce cost at the same time. To examine the mechanical properties of the samples
(with and without ultrasonic excitation), polishing and nanoindentation have been carried out. This report would
demonstrated different techniques that polishing samples and performing nanoindentation required, followed by
preliminary data obtained from nanoindentation testing indicating hardness and Young modulus of metallic 3D printed
sample with and without Ultrasonic Excitation. Repetition of nanoindentation are required in order to have conclusive
result on the mechanical properties deviation from samples with or without Ultrasonic Excitation.

Study of Flexible Wing Kinematics of a Free-Flying and/or Controlled-Flying Dragonfly
Supervisor: QIU Huihe / MAE
Student: HO Man Lee / AERO Course: UROP1100, Fall

This project is aimed to design a flexible flapping wing for micro air vehicles that can simulate the flight of a dragonfly.
This is a progress report explaining the methodology of the design process and the stage we are right now. The study of
the mechanical properties and structure of the dragonfly wing and the flight characteristic is the first step of the projects,
and therefore experiments were set up to measure the properties of dragonfly wing and visualize the flapping pattern
and air flow when dragonfly flapping. Then a simplified model of the dragonfly wing was used to imitate the wing of the
dragonfly and this is the stage right now. After this, the wing will put to mimic the flapping pattern of actual dragonfly.
Ultimately, a set of wings for the MAV to perform flight close to dragonfly is designed.
