China's first carrier rocket for commercial use is scheduled to make its maiden flight in the first half of 2019, according to the China Academy of Launch Vehicle Technology (CALVT). The rocket, named Smart Dragon-1 (SD-1), is the first member of the Dragon series commercial carrier rockets family to be produced by CALVT, as China accelerates the development of commercial space industry. China's current carrier rockets all belong to the Long March family. CALVT launched the design and development of the small-scale, solid-propellant rocket in Feb. 2018. The SD-1, with a total length of 19.5 meters, a diameter of 1.2 meter, and a takeoff weight of about 23.1 tonnes, is capable of sending over 150 kg payloads to the solar synchronous orbit at an altitude of 700 km. Since the rocket is designed especially for commercial use, its cost for sending payloads per unit into orbit is lower than that of similar rockets in the international market, according to CALVT. It takes only six months to produce one such rocket, and 24 hours to prepare for the launch. It can be used for launching either single satellite or multiple satellites at a time. "In addition to the Smart Dragon solid-propellant carrier rockets, CALVT will also develop liquid-propellant commercial rockets, which will have a higher carrying capacity," said Tang Yagang, president of the China Rocket Co. Ltd., affiliated to CALVT. "Innovation technologies will be introduced to promote the development of commercial space industry in China and to meet market demand." Source: Xinhua News
German engineers produce and test 3D-printed rocket engine Berlin (Sputnik) Mar 05, 2019 The new method will allow the weight and production cost of a rocket to be reduced, while increasing payload and implementing more sophisticated cooling systems. German Aerospace Centre (DLR) in collaboration with SLM Solutions, have successfully created a rocket engine, called BERTA, fully assembled using 3D-printing technology. The engine, which will be used in an Ariane 6 modular rocket developed by the ArianeGroup for the European Space Agency (ESA), is capable of delivering satellites to geos ... read more
