In a crucial milestone in the development of next-generation hypersonic munitions, the Defence Research and Development Organisation (DRDO) has successfully demonstrated a cutting-edge active cooled scramjet combustor ground test for 120 seconds for the first time in India. This is part of the efforts to develop a long-duration supersonic combustion ramjet or scramjet powered hypersonic technology.

The key to hypersonic vehicles is scramjets, which are air breathing engines capable of sustaining combustion at supersonic speeds without using any moving parts, DRDO noted in a statement. “The ground test of scramjet combustor showcased several notable achievements, demonstrating its potential for operational use in hypersonic vehicles, like successful ignition and stable combustion,” it stated.

This was developed by the Defence Research & Development Laboratory (DRDL), a Hyderabad-based laboratory of the DRDO.

Hypersonic missiles are a class of weapons that travel at speeds greater than Mach 5 – five times the speed of sound or more than 5,400 km/hr. Several nations including the U.S., Russia, and China are actively pursuing hypersonic technology.

Ignition in a scramjet engine is like ‘keeping a candle lit in a hurricane’, the DRDO said. Explaining this, the statement said that scramjet combustor incorporates an innovative flame stabilisation technique that holds continuous flame inside the combustor with air speed in excess of 1.5 km/s. Many novel and promising ignition and flame holding techniques were studied through many ground tests in arriving at scramjet engine configuration, it said. “The indigenous development of endothermic scramjet fuel, the first time in India, jointly by DRDL and Industry is central to this breakthrough. The fuel offers dual benefits of significant cooling improvement and ease of ignition.”

Further, DRDO said that another key achievement is the development of state-of-art Thermal Barrier Coating (TBC) which is designed to withstand extreme temperatures encountered during hypersonic flight. A new advanced ceramic TBC having high thermal resistance and capable of operating beyond melting point of steel has been jointly developed by DRDL and Department of Science and Technology (DST) Laboratory. “The coating is applied inside the Scramjet engine using special deposition methods that enhance their performance and longevity. With demonstrated capabilities in stable combustion, enhanced performance and advanced thermal management, this breakthrough sets the stage for next generation hypersonic missions,” the statement added.

Mikhail Shatsky, deputy general designer and head of its software department of the Mars Design Bureau, a Russian company that develops missiles used in Moscow’s war with Ukraine, has been killed, according to Kyiv Independent.

He was shot dead by an unknown assassin in Kuzminsky Forest Park, at Kotelniki, eight miles southeast of the Kremlin in the Moscow region, according to the Astra Telegram channel and other Russian and Ukrainian sources.

Shatsky was employed by a company that creates and produces onboard guidance systems for the Russian space and military industries. It has been a part of the state corporation Rosatom’s department since December 2017.

He was also an associate professor and was working actively on upgrading the Russian Kh-59 cruise missile to the Kh-69 level, which Russian troops use to strike Ukraine.

According to Kyiv Independent, Shatsky was seen as the main proponent of incorporating AI technology into Russian drones, aircraft, and spacecraft.

Shatsky’s death was previously reported by Ukrainian-Russian anti-Kremlin journalist Alexander Nevzorov, who wrote on his Telegram channel that HUR “eliminated a particularly dangerous criminal.”

Nevzorov shared photos of a person resembling Shatsky lying dead in the snow. The man was reportedly killed in the Kuzminsky forest park near Kotelniki in Moscow Oblast. The Kyiv Independent could not verify all the claims.

“Anyone who is involved in the development of the Russian military-industrial complex and support of Russian aggression in Ukraine in one way or another is a legitimate target of the Defence Forces,” the source said.
