to supply Helios fuel tanks QUANTUM Technologies, USA, is to design, fabricate, test and supply composite hydrogen and oxygen tanks for the next generation of Helios fuel cell prototype aircraft. Developed by AeroVironment, Helios is an unmanned aircraft that could be used to carry scientific and telecommunications equipment at much lower costs than satellites. Quantum says that its composite tanks will play a vital role in enabling the aircraft to reach its target of flying continuously for periods as long as six months at altitudes up to 18 km. Helios is one of several remotely piloted aircraft being

developed for NASA’s Environmental Research Aircraft and Sensor Technology (ERAST) project and is based on the Centurian aircraft launched in 1998 (ReinforcedPlastics, March 2001, page 86). The majority of its components are made using carbon fibre, carbon/epoxy and Kevlar composites. During a test flight this summer, Helios set a new altitude record for a non-rocket powered aircraft when it reached a height of 25 km. Helios’ 75 m wingspan is longer than that of a Boeing 747 airliner and it weighs just 700 kg, which is less than most cars. Quantum Technologies; website: www.qtww.com.

Japan’s H-IIA launch vehicie.
Japan’s new H-HA space launch vehicle. ATK Thiokol Propulsion Company, Utah, designed the composite rocket motor case for the H-IIA vehicle’s two ground-lit solid rocket boosters, using its patented TCRTM carbon flbrelepoxy prepreg. The H-IIA family of launch vehicles will comprise five separate vehicle configurations and ATK says its composite rocket motor case will be used on all of them. The H-IIA vehicle flown on the maiden flight is designed to be capable of placing payloads weighing up to 4 tonnes into orbit. The National Space Development Agency of Japan (NASDA)‘s next H-IIA flight is scheduled for early 2002. ATK; tel: +I-952-931 -6000; website: www.atk.com.
