The Project

The birth of the Aeronautics Project coincides with the foundation of Aristotle Space and Aeronautics Team (A.S.A.T.) in October 2015. The Project’s initial goal was to participate in a worldwide aerospace competition, the Air Cargo Challenge (ACC) 2017. With that in mind, Nephele I, the team’s first Unmanned Aerial Vehicle (UAV) was designed and constructed. This was an experimental layout that would test the skills and experience of the team in the field of UAV design. With the completion of the first flights of Nephele I, crucial data and experience was obtained, leading to the creation of the optimized Nephele II, a hybrid aircraft mainly constructed from balsa wood and carbon fiber. The participation in the ACC 2017 with Nephele II was a significant milestone, as we managed to achieve the 12th place among 36 participants, the 1st place among the newcomers and the 1st place among the Greek teams.

Important changes in the Project’s structure followed and the new members, aiming at enhancing their technical and theoretical knowledge, decided to participate in the ACC 2019 with two UAVs based on different configurations. The competition took place in Stuttgart, Germany. Our team’s first UAV was Nephele III, which was constructed using the same methods as its two predecessors, but showed improved performance. The second UAV, named Aurora, was a completely new aircraft layout, following the motor-glider configuration. It was constructed mainly from composite materials, which was a huge step for our team in terms of new design principles and manufacturing techniques. Aurora is also the fastest and largest, in terms of dimensions, aircraft the team has built so far. ACC 2019 turned out to be a success for our team, as Aurora and Nephele III got the 10th and 12th place respectively in the global ranking, while A.S.A.T. retained its title as the best aerospace team in Greece.

Continuing this journey, the members of the Aeronautics Project are aiming high with the optimization of the manufacturing methods used, the design of aircrafts featuring improvements on aerodynamic and structural aspects, as well as the development of automatic control systems.

the mask

The Aeronautics Project, in order to maintain the development of innovative UAVs, decided to design and build a solar-powered electric UAV. Some of the main objectives of the Solar Energy Management (SEM) sub-system are to study upon and select the solar panel system, implement the mandatory controllers and manage the power input of the air vehicle’s subsystems. The members are also engaged with the design and implementation of the charging circuit, as well as the battery management system.

Aerodynamics

The main objective of the Aerodynamics sub-system is to produce the optimum aerodynamic design, that will meet the mission’s requirements, while reducing the total drag of the UAV and achieving its static stability. To achieve the aforementioned, the members of the sub-system use a series of numerical tools written in MATLAB and conducts CFD analysis. Another aim is the prediction of the dynamic stability of the UAV, which is accomplished through the sizing of the control surfaces and the simulation of the UAV’s behaviour on crosswinds during the flight.

Structural

The Structural sub-system is responsible for the structural analysis of the UAV, as well as its construction. The members are responsible for the selection of the proper mechanisms, the connection of the individual parts and the operating systems, such as the landing gear, main wing and fuselage assembly. Furthermore, they select the construction materials and conduct their mechanical analysis.

Software Development

The Software Development subsystem’s main responsibilities are the research and development of an autopilot system and the development of a fire recognition system for the solar-powered UAV Phoenix.

Hardware Development

The Hardware Development sub-system’s main responsibilities are the development of flight measurement systems, the collection, and processing of flight data, the implementation of a telemetry system in cooperation with the Communications sub-system, as well as the UAVs’ electric equipment, such as servomotors, batteries and ESCs (Electronic Speed Controllers).

Communications

The Communications subsystem’s main responsibility is the development of telecommunication systems, which will allow us to monitor flight data in real-time, as well as to remotely control the solar-powered UAV Phoenix.
