Rocketry Project is the first of its kind in Greece. It was founded in October 2016 by engineering students with the goal of furthering human advancement and interest in rocket flight and its possibilities. Research rockets are a simple, cost-effective and time efficient way of testing experimental payloads which are the ultimate goal of rocket’s launch.

However, its main goal is to participate in Spaceport America Cup (SAC) 2020, which is the world’s largest Intercollegiate Rocket Engineering Conference and Competition, taking place in U.S.A. The competition’s goal is to design, build and fly a rocket to 10.000 feet AGL (Above Ground Level) with outmost accuracy and safely recover it, with a parachute, with minimum damages.

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

Propulsion

This sub-team is responsible for the research and development of a SRAD 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.

Structural

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 subteam works on the implementation of various components. The members are responsible for designing trustworthy rocket locating systems, flight data storage and retrieval systems such as altitude, speed and acceleration as well as to trigger the parachute opening by activating the ignition system from the flight computer.

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 and manufacturing a functional payload of at least 8.8 lb with the intention of competing in the SDL Payload Challenge at the SAC.

Operations

This sub-team is responsible for all the logistics staff of the project from the orders to the transportation to U.S.A. and the financials of the project. They also study all the safety rules and procedures that should be followed and implemented according to the SAC for the launches, motor’s static tests etc.

 

The team has manufactured scale models of the rocket Hyperion, intended
to fly at the SAC competition, in order to test the propulsion systems,
aerodynamic stability and validate their design methods.
