Punch Industry's Contribution to the RV-X Reusable Rocket

Punch Industry has recently marked a significant achievement in the aerospace sector with its involvement in the Japan Aerospace Exploration Agency (JAXA)'s RV-X project. On July 11, 2023, JAXA successfully conducted a flight test of the RV-X, a small prototype of a reusable rocket, at its Noshiro Rocket Experimental Facility in Akita Prefecture. This test not only demonstrated the viability of the RV-X's flight capabilities but also emphasized the potential advancements in reusable rocket technology that could revolutionize space travel.

What is the RV-X?

The RV-X is part of Japan's efforts to develop a reusable space transportation system. It aims to separate and land the first stage of larger rockets for future missions, ultimately reducing launch costs. The flight test executed by JAXA showcased the rocket ascending to about 10 meters, moving horizontally for approximately 15 meters, and subsequently performing a vertical descent to land. As Japan has yet to experience landing large rockets, this test lays the foundation for basic research in guidance and control technology necessary for such operations.

During the successful flight, the RV-X took off, maneuvered through the designated trajectory, and landed safely, thus opening up new opportunities for increased launch frequency and significantly reduced costs associated with access to space. The implementation of reusable rockets will help streamline space travel by allowing hardware to be reused, cutting down on resource consumption and waste during manufacturing—making this a pivotal step from a sustainability perspective.

How Punch Industry Fits In

Punch Industry is known for its high-precision metal processing techniques, which play a vital role in the aerospace sector. The company provides crucial components such as the quick disconnects used in the umbilical systems that connect the ground support equipment to the RV-X during fuel loading operations. These quick disconnect fittings ensure that fuel lines can safely retreat from the rocket engines, which burn at temperatures exceeding 3,000°C, while maintaining airtight seals to prevent leaks.

Components are manufactured at Punch’s facilities in Kitakami and Miyako City, both located in Iwate Prefecture, where precision is key. The connections between the hoses and the rocket are designed with a roundness accuracy of just 0.001 mm to ensure airtightness. The technology allows for seamless operation even under extreme conditions—like those involving super-cooled liquid hydrogen at minus 253°C—ensuring that connections remain unhindered for quick fuel line retraction upon engine ignition, thus preventing any fuel leaks.

Future Developments in Reusable Rocket Technology

The successful RV-X tests represent an initial phase of system-level technological research necessary for the reusable transportation system. Going forward, developments will transition into the next experimental phase with a project named CALLISTO, in collaboration with German and French partners, highlighting the international aspect of space technology advancements.

Punch Industry's Commitment to Aerospace

Since 2016, Punch Industry has focused its R&D efforts on expanding its role in the aerospace sector. The company has made strides in producing components relevant to aerospace, collaborating with various universities and sectors. This includes partnerships with aerospace technology ventures, notably working on the lunar rover “YAOKI” which will provide valuable data from the Moon's surface.

As part of its continuous efforts, Punch has already established a relationship with JAXA, focusing on advanced metallic hybrid techniques. In August 2023, a collaborative research contract was signed to explore rocket engine component manufacturing using its proprietary P-Bas® technology. Punch Industry stands committed to enhancing its capabilities within the aerospace industry, which is a central theme in its mid-term management plan, “Value Creation 28.”

With ongoing developments and studies aimed at increasing access to space, the knowledge and technologies derived from these aerospace initiatives could be channelized into existing and new business operations on Earth, making Punch a pivotal player in the realm of manufacturing and technology.
