JEJU, South Korea — The Korean Aerospace Research Institute (KARI) plans to launch a one-off rocket in 2017 to test its Woorae-1 rocket engine, the key technology of its forthcoming KSLV-II space launcher. The KSLV-II, a largely indigenous successor to the much smaller Russo-Korean KSLV-I launched between 2009 and 2013, is due to make its first flight in 2020.
Japanese engineers have ground tested a turbojet in conditions equivalent to Mach 4, which they believe is the highest simulated speed at which a turbine engine has operated. The February round of tests was a step toward building an engine that, unlike ramjets, has the thrust and efficiency advantages of mechanical compression and the ability to propel an aircraft from takeoff to Mach 5.
