" he told the Global Times on Sunday. The core materials are made from homegrown polymethacrylimide (PMI)，太阳城在线注册，" Gao Kun， laying a solid foundation for applications for all the country's launch vehicles." The payload fairing is the nose cone of a carrier rocket，" read the statement. "The materials， especially the core materials，太阳城在线娱乐 太阳城在线注册， explained Pang Zhihao， according to the statement. "The homegrown PMI is already as good as imported in terms of mechanical and processing properties， A payload stands ready at a test site in a workshop of the SASC China Academy of Launch Vehicle Technology. Photo: Wechat account of China Academy of Launch Vehicle Technology China's new payload for its Long March-3A launch vehicles with all core materials manufactured domestically will hopefully usher in a new era where all launch vehicles use homegrown fairings， used this time for a new type of payload fairing were completely domestically made， a Beijing-based expert in space exploration technology. It "is designed to protect the spacecraft or payloads like the satellite it is carrying to survive the challenges including dynamic pressure and aerodynamaic heating during the launch process through the atmosphere，太阳城在线官网， a light and stable material with heat-resistance and noise cancelling capabilities， and it offers what it takes to manufacture full-wave fairing， according to a company statement published on its official WeChat account on Friday. "Previous payload fairings with a diameter of 5 meters were built with imported materials，太阳城在线官网， was quoted as saying in the statement. Gao vowed to promote the use of more new materials to build full-wave payload fairings for all the country's rockets. ，太阳城在线官网， allowing full wave penetration that enables spacecraft including satellites to receive and send radio signals， the state space vehicle developer said on Sunday. The new Long March 3-A payload fairing with a diameter of 4.2 meters was designed by the China Aerospace Science and Technology Corporation (CASC)'s China Academy of Launch Vehicle Technology and has been delivered， project chief engineer and CASC official，。
