Rocketry Project is the first of its kind in Greece. It was founded in October 2016 by engineering students with the initial goal of engaging University students in Rocket Science. After the knowledge and the experience which was gained, the goals were separated into the two main goals of the project.

The first goal is to introduce Rocket Science to the Greek community and its Academic Institutions in order to further develop this field and create a network of individuals, groups, and companies around it.

The second goal is to compete to the Spaceport America Cup (S.A.C.) competition, which is the world’s largest student rocketry competition, which takes place in the United States. The mission of the competition is to design, manufacture and launch a rocket in a variety of categories depending on the altitude and type of the rocket’s propellant. Our project targets 10.000 feet A.G.L. (Above Ground Level) using a solid propellant motor, aiming for the highest possible elevation accuracy and safely recovery by using parachutes and thus making the rocket reusable.

The team incorporates many S.R.A.D. (Student Researched and Developed) components in the design of its rockets. The motors used for the team’s flights are S.R.A.D. solid propellant rocket motors. For data acquisition during flight, the team uses an S.R.A.D. flight computer for detecting apogee and tracking the vehicle’s flight dynamics. Many other components like the body tube, fins, nose cone, parachute’s ejection mechanism, etc. are also S.R.A.D.

Propulsion

This sub-team is responsible for the research and development of an S.R.A.D. solid rocket motor. More specifically their goal is:

  • designing and manufacturing the rocket motor
  •  simulation and analysis of the motor’s performance
  •  manufacturing of solid propellant
  •  studies in the chemistry of combustion and also
  •  the static test of the rocket motor

Aerodynamics

This sub-team is responsible for modeling the trajectory, aerodynamic properties and stability characteristics of the rocket and also for minimizing the drag force on it. This is accomplished through wind tunnel testing and CFD analysis (which predict the drag coefficient) and other analysis tools. Its goal is to design a stable flying rocket.

Construction

This sub-team is responsible for the design, manufacture and analysis of the rocket’s structural parts. These parts include:

  • the body tube
  •  the internal components
  •  the nose cone and
  •  the fins

More specifically, its core competence is to design the rocket parts with such strength that they could withstand the imposed loads during the flight and be as lightweight as possible. This is achieved by the use of specialized materials, such as composite and metallic materials, and with continuous training in new methods of manufacturing them. In addition, great emphasis is placed on the proper assembly of the different rocket parts, providing easy access where it is necessary, as well as robustness in the overall rocket. All the above are confirmed with the use of analysis programs as well as in static tests. Finally, the design and construction of the launch infrastructure is another competence of the construction sub-team.

Avionics

This sub-team works to implement hardware solutions. The members are responsible for the design of reliable communication systems capable of real-time flight data acquisition such as altitude, velocity, and acceleration, as well as for triggering the parachute’s deployment through the flight computer and the development of the ignition system.

Recovery

This sub-team is responsible for the design and manufacture of the drogue and main parachute for use in recovering the rocket safely, after it has reached its apogee, and the development of the parachute’s ejection mechanism.

Payload

This sub-team is responsible for designing a functional payload that will be housed inside a rocket and will be conducted throughout the flight. The payload must conduct an experiment which is usually of biological, medical, chemical or other nature.

Safety

This sub-team is responsible for implementing and enforcing safety rules in the field of High Power Rocketry. Part of the rules is set by the N.F.P.A. (National Fire Protection Association), T.R.A. (Tripoli Rocketry Association) and S.A.C. The rest are general laboratory rules as well as specific rules as set out in the Material Safety Data Sheet.

Operations

This sub-team is responsible for managing all of the Project's finances, budget overseeing and re-budgeting, conducting orders, organizing flight operations (transportation, etc.) and many other micro-processes of the Project.
