ATK rocket motor case and advanced composite material technologies supported the successful maiden launch today of Japan's new H-IIA space launch vehicle on Wednesday.
In a unique arrangement and in cooperation with IHI Aerospace Co., ATK Thiokol Propulsion Company designed the composite rocket motor case for the H-IIA vehicle's two ground-lit Solid-Rocket Boosters (SRB-As). The company also supplied graphite-epoxy, preimpregnated resin materials for use in constructing the case.
The H-IIA family of launch vehicles, which will comprise five separate vehicle configurations, is being developed under the direction and funding of the National Space Development Agency of Japan (NASDA). All five configurations will feature ATK's rocket motor case and composite technology.
The H-IIA vehicle configuration flown on the maiden flight has an LE-7A liquid engine in the core and two SRB-A motors, and is capable of placing payloads weighing up to four metric tons into orbit. The first vehicle did not have a satellite payload, but carried a three-ton weight to simulate future spacecraft loads and a mirrored ball to test for orbital insertion. NASDA's next flight of the H-IIA is scheduled for early 2002.
Solvay has signed a ten-year agreement for the supply of composites and adhesives to be used across Bell's military and commercial rotorcraft programmes, including the Bell 429, 407, 505, 525, V-22, and UH-1.
SGL Carbon and Fraunhofer IGCV have officially opened the Fibre Placement Centre (FPC) at SGL's site in Meitingen, Germany. Compositence, BA Composites and the Chair for Carbon Composites at the Technical University of Munich have also joined the alliance, and Coriolis Group and Cevotec are planning to come on board as partners.
With the aim developing a broader platform for additive manufacturing (AM) technologies, the University of Exeter, UK, and Victrex, have formed a strategic partnership to introduce next-generation polyaryletherketone (PAEK) polymers and composites while improving the performance of the underlying AM processes.
