How far away India equipment hypersonic vehicle? Weidong: have at least five years!
September 7th, the Indian Defense Ministry and development organization successful test flight of the hypersonic vehicle developed independently, they are excited to announce that India is the second after Russia, the US, China's fourth country with hypersonic aircraft. If it is to successfully test hypersonic vehicle, at least to address three key issues: first, with the reasonable aerodynamic configuration; second, high temperature materials; third, engine to cross the border. If you resolve these three issues, it really is extraordinary. But India flight test of the hypersonic vehicle, though with a ramjet engine, but it is by "Agni" missile ship it on the high altitude, flying time is only 20 seconds, limited flight distance, whether to control the direction of flight also unknown. US X-51A hypersonic unmanned aircraft 10 years ago, has been tested successfully, and it is longer than the time of flight of India, but for technical reasons it still can not do the engineering, mass production setting. Then according to India's current level of industrial and technological level, in order to shape the hypersonic weapons, equipment, and India there are many problems to be solved.
