Collected all the technologies they developed into a thesis under the title, "Standardization of Overall Amateur Solid-Propellant Rocket Production Technology"

The central club “TUSI” has received the Minister of Science and Technology Award at the university rocket competition and produced a thesis on the theme of "Standardization of Overall Amateur Solid-Propellant Rocket Production Technology." The club members said, "We put in much hard work into make rockets with people who like rockets, and we are proud of the good results."

Founded in 1985, TUSI is a central academic club that focuses on solid-propellent rocket production and implementation. The club has a long and illustrious history, boasting many awards it earned, but the COVID-19 pandemic forced TUSI into difficulties. The accumulated knowledge and know-how of TUSI's rocket-related technology, which was largely transmitted verbally and in practice between each generation of student members, was lost as all university club activities went into a hiatus due to COVID-19. To make the matter worse, there was no professor to supervise the club and take charge of technical guidance.

The club members, however, were determined to reverse the downfallen atmosphere of the club with a new spirit and recreate the glory of the past. After the loss of technology, the focus of the club activity was set on the standardization of knowledge and technology they had. Student Sung-hyun Park said, "We decided that we should record and organize into writing all the rocket technology we currently have so that the future generation of TUSI members will be able to continue our work and develop the technology in the future on the basis of these records." "While we have completed the thesis, we have not yet reached the goal of complete standardization of our knowledge. We plan to continue the research until next year," Student Yo-han Kim explained.

The rocket technologies standardized in this thesis are parachute injection, engine, fuel, and others. The engine is a key part of the rocket launch but the technology the club once had was lost due to COVID-19. There were design drawings of engines manufactured in the past by the previous generations of the club, but there was little in the way of detailed development records on how they arrived at the design and what was the reason behind the decision. Therefore, they had to design a new engine structure from scratch that had different performance characteristics compared to the previously built engines.

Fuel was the most difficult part of the standardization. Student Ki-won Lee said, "Fuel is particularly difficult to standardize, and the engine performance varies widely depending on which fuel mixture is used under what condition, so the key challenge was to keep the quality of fuel constant." The thesis included the fuel production process and preservation methods. "As the aerospace sector is becoming popular, more and more university clubs are entering rocket competitions. I hope that we share the thesis with other universities so it can help increase the overall technological level of university rocket student clubs," hoped Student Sung-Hyun Park.

The club also took advantage of the strengths of being a central club, which can widely recruit students with diverse majors instead of being part of one specific academic department. Rocket manufacturing requires expertise in various fields. For example, engines require mechanical engineering, and expertise in software and communication to control the flight data. Student Yo-han Kim said, "Students from various majors participated and were able to utilize their expertise in different areas."

The club members are from various departments and majors within Kyung Hee, but the single interest, rocketry, united them. When asked about the draw of rocketry, students answered ”curiosity.” Student Seung-beom Ahn said, "Curiosity is a unique characteristic of human nature. Our history is a history of curiosity that compels us to explore the unknown worlds. The rocket that explores space, the one of the last unknown frontiers, stimulates curiosity.”
