China tests three hypersonic missiles


China has achieved a rare feat of testing three types of hypersonic aircraft missiles at the same time, a media report said.

The tests of three scaled-down models of 'wide-speed-range vehicles', which can fly at from hypersonic velocity to lower than the speed of sound, were carried out on September 21 at the Jiuquan Satellite Launch Centre in northwest China.

In the news footage, three models representing differently shaped designs, code-named D18-1S, D18-2S and D18-3S, were lifted and then dropped from a balloon. This was China's first test of this type of aircraft, whose speed will be adjustable, meaning its scientists are working on another major aim - precision strike - towards an unstoppable nuclear-capable weapon, the South China Morning Post said.

Last month, Chinese scientists conducted their first experimental flight of a hypersonic glider, Starry Sky 2, that was launched by a rocket and then flew on its own shock wave at Mach 6 (six times the speed of sound). Once fully developed, its sheer speed would be capable of penetrating any anti-missile defence system currently available.

The wide-speed-range aircraft, meanwhile, will have additional capability to slow down and fly in a stable mode at a lower velocity, which allows it in the terminal stage to aim, adjust trajectory and position and strike targets more precisely.

'Their technologies can be inter-complementary,' said military commentator Song Zhongping, based in Hong Kong. 'They can be combined together and make a hypersonic missile.' Researchers measured the respective features of three different design shapes and recorded their processes of falling, accelerating, breaking the sonic barrier, aerodynamic rebound, parachute opening, landing and retrieving while collecting data.

M. Song said it was to compare and choose from the three designs. There will be further wind tunnel tests with larger or real-size models before finalising the aerodynamic configuration of the vehicle.
