In an impressive display of innovation and engineering prowess, the Aerospace Team Graz, a student collective from Graz University of Technology, has once again ascended to the pinnacle of European rocketry. At the sixth edition of the European Rocketry Challenge held in Constância, Portugal, this formidable team secured the championship title for the second consecutive year, reaffirming its dominance in the field of rocket construction. Their winning rocket, ISPIDA, named after a distinctive kingfisher subspecies, clinched an extraordinary 938 points out of a possible 1000, overshadowing the competition by a substantial margin of over 220 points ahead of the University of Stuttgart, which took second place. The Polytechnic University of Milan rounded out the top three, contributing to a fiercely competitive environment among the 24 participating teams.
The European Rocketry Challenge is renowned not only for fostering innovation but also for its rigorous evaluation criteria. The contest’s scoring system is meticulously designed to assess a spectrum of competencies across four distinct areas: technical documentation, rocket design, team performance, and flight performance. Technical documentation carries a weightage of 200 points, evaluating the clarity, thoroughness, and technical precision of the teams’ reports and papers. Rocket design is scrutinized with a weight of 250 points, focusing on the ingenuity, reliability, and efficiency of the rocket’s architecture. Team performance, gauged with 200 points, considers collaboration, problem-solving, and project management skills. Most critically, flight performance dominates the scoring with 350 points, assessing the real-world capability of the rocket to achieve its design goals in terms of altitude, stability, and safety.
At the core of the Aerospace Team Graz’s success lies the ISPIDA rocket, which competed in the highly challenging H9 class. This category encompasses rockets equipped with hybrid propulsion systems and is characterized by a flight target altitude of approximately nine kilometers. ISPIDA’s propulsion system is particularly noteworthy for its sophisticated use of hybrid technology, employing nitrous oxide as the liquid oxidizer alongside hydroxyl-terminated polybutadiene (HTPB) as the solid fuel. This combination leverages the benefits of both liquid and solid propellants: the controllability of liquid oxidizers and the energy density of solid fuels, resulting in remarkable thrust-to-weight ratios and fuel efficiency. During the competition, ISPIDA flawlessly reached an altitude of 9,366 meters, surpassing its targeted height and earning the Flight Award in its class, a testament to the team’s meticulous engineering and rigorous testing protocols.
Behind this extraordinary achievement is a nearly year-long journey of preparation, a process blending conceptual development, engineering design, rigorous testing, and relentless refinement. Manuel Maurer, the team president, emphasized the breadth and depth of this journey, noting that the team comprises approximately 90 dedicated members. Each individual brings unique expertise and an unwavering commitment that collectively propels the project’s success. According to Maurer, the preparation phase involves not only technical development but also securing sponsorships, managing logistics, and addressing manufacturing challenges, all of which require precise coordination and strategic leadership to harmonize the multifaceted components of the project.
Interdisciplinary collaboration stands as a cornerstone of the Aerospace Team Graz’s philosophy. Composed of members across 15 fields of study, the team integrates knowledge from mechanical engineering, electrical engineering, physics, and computer science to optimize rocket design and system integration. This diverse expertise enables comprehensive problem-solving, from the structural dynamics involved in the rocket frame to the sophisticated avionics systems that govern flight control. In addition to technical fields, important contributions come from sectors such as management, marketing, media production, and public relations, which are instrumental in fostering partnerships and enhancing the team’s visibility and funding opportunities, thereby ensuring the sustainability and growth of the project.
The rocket’s propulsion system, instrumental in the team’s success, deserves closer technical scrutiny. The choice of a hybrid system underscores the quest for a balance between performance, safety, and cost-effectiveness. Nitrous oxide, a monopropellant with self-pressurizing properties, acts as the oxidant and is known for its stability and ease of handling compared to other liquid oxidizers such as liquid oxygen. HTPB solid fuel provides a flexible grain design that enables precise adjustment of burn rates and thrust profiles. This combination results not only in improved thrust management but also enhances operational safety by mitigating risks associated with pure liquid propellants. The ISPIDA rocket’s design thus demonstrates an advanced understanding of hybrid propulsion’s advantages, paving the way for new standards in amateur and academic rocketry.
Flight dynamics and control also played pivotal roles in the success of ISPIDA. Achieving a stable and efficient flight path at altitudes nearing ten kilometers involves complex aerodynamic design and precise real-time control algorithms. The team’s engineers utilized state-of-the-art modeling and simulation frameworks to optimize the rocket’s shape, mass distribution, and fin design, ensuring minimal drag and maximum stability during ascent. Moreover, sophisticated onboard computer systems manage motor burn duration, thrust vectoring, and recovery sequences. These systems are paramount in ensuring not only peak performance but also safe retrieval and reusability, which are key considerations in sustainable rocketry initiatives.
The European Rocketry Challenge itself provides an inspiring platform for young engineers to transition theory into practice. It serves as a rigorous proving ground where emerging scientists and engineers test their skills against real-world constraints such as material limits, environmental variables, and performance expectations. The competition’s structure encourages incremental innovation and fosters a spirit of camaraderie among diverse teams across Europe. The Aerospace Team Graz’s back-to-back victories underscore the value of sustained investment in education, research infrastructure, and inter-institutional collaboration, foreshadowing the broader technological breakthroughs that such academic challenges can help nurture within the aerospace industry.
The significance of the Aerospace Team Graz’s repeated triumph extends beyond mere titles. Their achievements spotlight the growing relevance of hybrid propulsion systems and interdisciplinary methodologies in the future of rocketry and space exploration. The knowledge and experience generated through such student-led ventures often translate into pioneering technological advancements, fueling larger scale commercial and scientific endeavors. Moreover, the team’s highly publicized success provides a beacon of inspiration for aspiring engineers and scientists, emphasizing the empowering potential of academic collaboration, creativity, and perseverance in pushing the frontiers of human capability.
Manuel Maurer’s reflections on the collective achievement also highlight the deep-rooted culture of mutual respect, dedication, and innovation within the team. His acknowledgment of every member’s contribution exemplifies the essential human element underlying technological success. From initial brainstorming sessions to the critical countdown moments of the rocket launch, each phase demanded precision, coordination, and resilience. The Aerospace Team Graz’s story is not just about building rockets—it’s about building a generation of forward-thinking engineers equipped to tackle the aerospace challenges of tomorrow.
With their continued dominance at the European Rocketry Challenge, the Aerospace Team Graz has solidified its reputation as a leader in student rocketry. Their innovative hybrid rocket ISPIDA is a stellar example of how scientific rigor combined with creative engineering can achieve extraordinary outcomes. As the team looks ahead to future challenges, their triumph in Portugal stands as a milestone, fostering both technical excellence and collaborative spirit, thereby shaping the future trajectory of rocketry education and research.
