China tests three hypersonic missiles at one go
Beijing, Sep 30 : China has achieved a feat of testing three types of hypersonic aircraft missiles at the same time, a media report has 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, according to state broadcaster CCTV.
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 hypersonic 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 named Starry Sky 2 that was launched by a rocket and then flew on its own shockwave at Mach 6 (six times the speed of sound or 7,344km/h).
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, according to military observers.
"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 aerodynamic 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, CCTV said.
Song Zhongping 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.

Supreme Court rejects plea for reverting to ballots in elections
New Delhi (PTI): The Supreme Court on Tuesday dismissed a petition seeking to revert to ballot paper voting in elections in the country.
"What happens is, when you win the election, EVMs (electronic voting machine) are not tampered. When you lose the election, EVMs are tampered (with)," remarked a bench of Justices Vikram Nath and P B Varale.
Apart from ballot paper voting, the plea sought several directions including a directive to the Election Commission to disqualify candidates for a minimum of five years if found guilty of distributing money, liquor or other material inducement to the voters during polls.
When petitioner-in-person K A Paul said he filed the PIL, the bench said, "You have interesting PILs. How do you get these brilliant ideas?".
The petitioner said he is the president of an organisation which has rescued over three lakh orphans and 40 lakh widows.
"Why are you getting into this political arena? Your area of work is very different," the bench retorted.
After Paul revealed he had been to over 150 countries, the bench asked him whether each of the nations had ballot paper voting or used electronic voting.
The petitioner said foreign countries had adopted ballot paper voting and India should follow suit.
"Why you don't want to be different from the rest of the world?" asked the bench.
There was corruption and this year (2024) in June, the Election Commission announced they had seized Rs 9,000 crore, Paul responded.
"But how does that make your relief which you are claiming here relevant?" asked the bench, adding "if you shift back to physical ballot, will there be no corruption?".
Paul claimed CEO and co-founder of Tesla, Elon Musk, stated that EVMs could be tampered with and added TDP chief N Chandrababu Naidu, the current chief minister of Andhra Pradesh, and former state chief minister Y S Jagan Mohan Reddy had claimed EVMs could be tampered with.
"When Chandrababu Naidu lost, he said EVMs can be tampered with. Now this time, Jagan Mohan Reddy lost, he said EVMs can be tampered with," noted the bench.
When the petitioner said everybody knew money was distributed in elections, the bench remarked, "We never received any money for any elections."
The petitioner said another prayer in his plea was the formulation of a comprehensive framework to regulate the use of money and liquor during election campaigns and ensuring such practices were prohibited and punishable under the law.
The plea further sought a direction to mandate an extensive voter education campaign to raise awareness and importance of informed decision making.
"Today, 32 per cent educated people are not casting their votes. What a tragedy. If democracy will be dying like this and we will not be able to do anything then what will happen in the years to come in future," the petitioner said.
