The NCKU submarine team recently achieved a new personal best at the 18th International Submarine Race. The event took place from June 23 to 27 at the US Naval Research Laboratory. The team recorded a top speed of 3.24 knots, marking significant progress. Primarily made up of students from the System and Naval Mechatronic Engineering Department, the NCKU submarine team focuses on improving hull design, propulsion, and system integration. Their work supports advancements in underwater vehicle technology. This dedication shows clearly in their latest performance.
This year, the competition hosted 17 teams from six countries, including the US, UK, Canada, Singapore, and Poland. Canada’s Omer 13 team set a new world record by reaching 7.68 knots. Despite strong competitors, the NCKU submarine team placed sixth in top speed and tenth in average speed. However, the team admits that their submarine’s stability and overall performance still require enhancement. They plan to use this experience to create a better, next-generation submarine. The lessons learned this year will drive future innovations.
During the event, the NCKU submarine team faced several technical problems. On June 24, the submarine hit the pool bottom and broke a propeller blade. After replacing it, another blade unexpectedly fell off on June 25. Thankfully, the remaining races went smoothly without further damage.Team captain Chen Chuan-jen highlighted the value of on-site adjustments. He said that calculating weight and buoyancy during the event proved crucial.
The 130-meter racecourse allowed the submarines to sprint at full speed, testing their capabilities thoroughly. Team member Shen Kuan-hung added that the course’s narrow width increased the challenge. Even minor mistakes risked collisions with the walls. Moreover, teams had only one week for assembly, fine-tuning, and racing. The NCKU submarine team had to be meticulous and prepared to handle all equipment independently.
Earlier, in June 2024, the team competed in the European International Submarine Races in the UK with their self-built submarine, Pegasus. Measuring 3.22 meters long and weighing 91 kg, Pegasus helped them secure fifth place and break their 2022 record. The NCKU submarine team’s progress reflects their commitment to pushing the boundaries of human-powered underwater vehicles. They continue to build on each race’s experience to innovate and improve.
