Watch India test its new homemade hypersonic vehicle
NEW DELHI — India on Monday conducted a successful test of a fully indigenous hypersonic technology demonstrator vehicle powered by an air-breathing scramjet engine, the Defence Ministry announced.
With the test, India joins the U.S., Russia and China in the race for hypersonic technology development.
The flight test took place Sept. 7 around 11 a.m. on an island off the coast of Odisha. The demo vehicle was indigenously developed by the government's Defence Research and Development Organisation, and it has the ability to fly at six times the speed of sound, according to defense scientists here.
The ministry said the hypersonic cruise vehicle was launched using a solid rocket motor, which took it to an altitude of 30 kilometers. Then the cruise vehicle separated from the launch vehicle and the air intake opened as planned, the ministry added.
“The successful demonstration proved several critical technologies including aerodynamic configuration for hypersonic manoeuvers, the use of scramjet propulsion for ignition and sustained combustion at hypersonic flow, thermo-structural characterisation of high-temperature materials, separation mechanism at hypersonic velocities, etc.,” DRDO said in a statement.
A top DRDO scientist told Defense News that the vehicle will be used to launch both hypersonic and long-range cruise missiles.
"DRDO has spent around $4.5 million on its [HTDV] prototype development cost, and three more tests will be carried out in the next five years to make this platform into a full-fledged hypersonic weapon that is capable of carrying both conventional and nuclear warheads, "he said.
DRDO spent about $30 million on the design and development phases.
Congratulating DRDO, Prime Minister Narendra Modi tweeted: “The scramjet engine developed by our scientists helped achieve a speed of 6 times the speed of sound! Very few countries have such capability today.”
Defence Minister Rajnath Singh called the test a “landmark achievement” toward India becoming self-reliant and less dependent on foreign technology.
“It's now time to progress to the next phase with all critical technologies being established by the successful [HTDV] flight test, using the indigenously developed scramjet propulsion system,” he added.

Lockheed Martin Uses Virtual Reality And 3D Printing To Reduce Injuries On The Job
BETHESDA, Md., March 26, 2019 – Four Lockheed Martin (NYSE: LMT) teams advance as finalists in the 22nd Applied Ergonomics Conference Ergo Cup® Competition, which showcases innovation aimed at reducing risk of injury in the workplace. Lockheed Martin will be one of over 20 companies discussing their ergonomic innovations in the Ergo Cup Competition. “With more than 100,000 employees developing a broad portfolio of products and solutions for national defense, cyber security, logistics and energy we must modernize our approach to ergonomics, safety and health,” says Lockheed Martin Fellow and Corporate Ergonomist Anthony Banks. “This requires new techniques and tooling. Some examples of this include 3D printed tools for helicopter assembly, performing ergonomic evaluations in a virtual environment, and drastically improving manufacturing applications. By focusing on safety, wellbeing and improved business practices, Lockheed Martin is committed to prioritizing sustainability to innovate for the future.” The Lockheed Martin teams competing include: Virtual Reality to Enhance Ergonomics Integration, THAAD Missile Canister Shock Isolator Compression Tool, Weightless High Torque Motor Application for F-35 Vertical Tails Installation and the CH-53K helicopter harness installation from Sikorsky, a Lockheed Martin company. Since their implementation in the workplace, each of the team's ergonomic innovations have yielded outstanding sustainability results and are projected to deliver continued cost savings. The 22nd Applied Ergonomics Conference (AEC) convenes in New Orleans March 25-28 for the annual meetup and exchange of ideas and best practices in ergonomics, healthcare, safety, human resources and risk management.
