Technological Innovation of Tuke Power Surfboard

1. At present, similar foreign products generally use carbon fiber autoclave molding technology, using T300 carbon cloth ( tensile strength   3.53GPa ), the size of the product is limited by the size of the autoclave and the energy consumption is high, resulting in high operating costs . Taking the Czech JETSURF, which is the mainstream in the market, as an example, the annual output is only about 5,000 units, which limits its production capacity and cannot meet the huge market demand.

Tuke Intelligent Technology Co., Ltd., through 4 years of research and development, brainstorming, practice and exploration, adopted a new RTM molding process, and replaced the two-step or multi-step infiltration process of the traditional molding process with one-step infiltration method , reducing the prepreg preparation. , lamination, vacuum bagging and curing in autoclave, which greatly reduces the molding time and molding cost, and adopts T700S aviation-grade carbon fiber (tensile strength 4.9Gpa) after molding and installed on the machine, which is completely in line with the design and use Requirements, and the research and development test successfully achieved the most advanced international compression molding technology, creating technical conditions for the realization of mass production.

Conclusion: The successful research and development of the company's "full plate carbon fiber composite molding technology" not only breaks through the long-term production capacity bottleneck of foreign counterparts, but also better solves the special needs of the product in terms of use environment and strength.

2. Generally speaking, high-speed, high-torque two-stroke internal combustion engines are usually used to power surfboards, which have high technical requirements, are expensive, and generally have certain design defects and insufficient work efficiency. More importantly, due to the technology monopoly and blockade of Western developed countries, the fuel powertrain system technology of domestic power panels is backward, and there is no mature industrial system for core components in China. However, international procurement is expensive, with a single unit costing more than 35,000 RMB. After contacting companies such as KTM, Japan’s Yamaha, and Canada’s Bombardier, the initial development costs are as high as more than 1 million euros, plus the later carbon fiber boards and ECU electronic control system accessories. Cost, no price advantage and industrial development.

After the establishment of Tuke Intelligent Technology Co., Ltd., it is committed to breaking the foreign blockade as the goal, self-innovating in the research and development of key core components and powertrain systems, and carrying forward the spirit of "pioneering first" on the road of localization, and being brave in practice Accumulate experience and obtain key core data: Since 2018, the company has been entrusted by the Water Sports Center of the State Sports General Administration to undertake the after-sales maintenance tasks of more than 50 JETSURF power surfboards imported from the Czech Republic, so as to ensure the national bidding of national power surfboards The normal progress of the competition, in-depth analysis, inspection of equipment problems, and search for technical solutions during maintenance. This provides a lot of perceptual knowledge and important technical parameters for our research and development. At the same time, the chief R&D engineer also took an active part in various water sports competitions to capture technical sensitive points in the competitions.

Through learning and accumulation, the R&D team independently designed and developed an engine with high reliability, sufficient power and stable operation in January 2019, and applied for the invention patent of the new two-stroke engine and the new utility patent for the ultra-small start clutch. The full carbon fiber structure high-speed water jet propulsion seeks the cooperation of the 702 Research Institute of China Shipbuilding Industry Corporation, and overcomes technical difficulties such as fluid simulation and load-bearing structure. The research and development and manufacture of 6 molding molds have successfully passed various tests and fully meet expectations. Design requirements, various technical parameters meet or exceed similar foreign products. The installed matching has been realized.

Conclusion: The successful research and development of the company's "new two-stroke engine" once again proves that practice is the most rigorous teacher and practice is the best standard. There are no technical barriers that cannot be broken through. As long as we persist in combining practice with theory and continue to try and make mistakes, we will surely achieve technological transcendence.
