Explained: China’s hypersonic glide vehicle test

A report in the London- grounded Financial Times on Saturday, citing colorful sources, says China in August tested a nuclear-able hypersonic glide vehicle that circled the globe before speeding towards its target. Hypersonic pets are 5 or further times the speed of sound.
The test, as reported

The FT report mentions five people familiar with the test as saying the Chinese military launched a rocket that carried a hypersonic glide vehicle, which flew through low- route space before cruising down towards its target. The test has caught US intelligence by surprise, the report says  The bullet missed its target by about two-dozen country miles, according to three people briefed on the intelligence. But two said the test showed that China had made astounding progress on hypersonic munitions and was far more advanced than US officers realised. The test has raised new questions about why the US frequently undervalued China’s military modernisation,” the report reads.

The report cites a security functionary, and another Chinese security expert close to the People’s Liberation Army, as saying the armament was being developed by the China Academy of Aerospace Aerodynamics (CAAA), under the state- possessed China Aerospace Science and Technology Corporation that makes bullet systems and rockets for China’s space programme. Both sources reportedly said the vehicle was launched on a Long March rocket, which is used for the space programme According to the report, two people familiar with the test said the armament could, in proposition, fly over the South Pole. That would pose a big challenge for the US service because its bullet defence systems are concentrated on the northern polar route.

The report quotes the China Academy of Launch Vehicle Technology as saying on an sanctioned social media regard on July 19 that it had launched a Long March 2C rocket, its 77th launch. On August 24, it blazoned a 79th flight. But there was no advertisement of a 78th launch, which sparked enterprise about a secret launch, the report notes “ The US, Russia and China are each developing hypersonic munitions, including glide vehicles that are launched into space on a rocket but route the earth under their own instigation,” the report says.

India’s DRDO tested a hypersonic vehicle in September last time. Asked about China’s test, a elderly DRDO scientist said, “ The exact details on technology used by China in this particular test aren’t known through media sources. But utmost of the hypersonic vehicles primarily use the scramjet technology. This extremely complex technology, which also needs to be suitable to handle high temperatures, makes the hypersonic systems extremely expensive. It’s each about how long can you sustain the systems at those extreme conditions. Utmost military powers in the world are in the process of developing hypersonic systems Scramjets are a a order of machines designed to handle airflows of pets in multiples of the speed of sound.

Counteraccusations for India

“ This test by China clearly needs to be watched nearly by the world, especially India considering relations with China in the recent history,” said Air Marshal Bhushan Gokhale (Retd), former Vice Chief of Air Staff. “ Similar capabilities also punctuate the trouble for our space means along with the face means. The offence system operating at these pets would mean demand to develop defence systems at these pets He added, “ India too is working on hypersonic technologies. As far as space means are concerned, India has formerly proved its capabilities through the test of ASAT.”

Hypersonic technology has been developed and tested by both DRDO and ISRO. Last September, DRDO successfully flight- tested the Hypersonic Technology Demonstrator Vehicle (HSTDV), with a capability to travel at 6 times the speed of sound. A solid rocket motor of Agni bullet took it to an altitude of 30 km where the voyage vehicle separated as planned. The hypersonic combustion sustained and the voyage vehicle continued on its asked flight path at a haste of six times the speed of sound for further than 20 seconds  The scramjet machine performed in a textbook book manner. With this successful demonstration, numerous critical technologies similar as aerodynamic configuration for hypersonic manoeuvers, use of scramjet propulsion for ignition and sustained combustion at hypersonic inflow, thermo-structural characterisation of high temperature accoutrements, separation medium at hypersonic rapidityetc. were proven.” DRDO had said in a statement Last December, an advanced Hypersonic Wind Lair (HWT) test installation of the DRDO was inaugurated in Hyderabad. It’s a pressure vacuum- driven, enclosed free spurt installation that simulates Mach 5 to 12.
