India Develops Powerful Pulse Detonation Engine For Cruise, Anti-Tank Missiles
Saturday, May 20, 2017 by Indiandefense News

The Defence Research and Development Organisation (DRDO) claims to have developed a pulse detonation engine which is more powerful and has higher fuel efficiency than the gas turbine engines of flying systems currently
New Delhi – A paper issued by the DRDO said the engine can be used in cruise and anti-tank missile propulsion, unmanned aerial vehicles. After the basic engine, the Terminal Ballistics Research Laboratory (TBRL), a unit of DRDO, is now working on air breathing multi-tube, multi-cycle pulse detonation engine.
“After achieving single shot detonation in a single tube in liquid fuel, TBRL has achieved multi-cycle operation of 8 Hz in single PDS tube. TBRL is working on air breathing multi-tube multi-cycle pulse detonation engine with an objective to develop an air-breathing Pulse Detonation Engine (with throttling) to generate 2.5 kN of thrust for a duration of 30 minutes,” said the DRDO paper.
“This is a major step in the direction of developing advanced pulse detonation system and should be applauded. However, the challenge of developing indigenous flying engine is far from over and would require few other technological breakthroughs,” Ajey Lele, a security analyst at the Institute for Defence Studies and Analyses, told Sputnik.
Pulse detonation system is a mechanically simpler engine in comparison to the gas turbine engine, wherein the combustion wave travels at supersonic speeds relative to the unburnt fuel-oxidizer mixture. It utilizes repetitive detonations of the fuel-oxidizer mixture to produce thrust. For flying systems, however, detonation requires a long tube length to accommodate required amount of energy input. TBRL has been working on a system to reduce the length of the engine so that it can be applied in systems like UAVs and other missiles system as well. “To reduce engine length, suitable devices are employed which reduce the length of the tube required for the transition from deflagration to detonation. A test rig was designed and established for conducting experiments with liquid fuel-air mixtures,” the paper added.
“Developing indigenous pulse detonation technology is a big achievement for Indian scientists. This technology is very important for the cruise, anti-ship missile and UAVs which will be used in manipulating speed and fuel efficiency of the missile or drones,” Rajiv Nayan, a missile technology expert said.
Last year in July-August, Russian scientists had successfully tested the first-ever pulse detonation rocket engine on clean fuel. Apart from Russia, the US became the first to have tested a pulse-detonation engine in 2008, though powering a plane and not a rocket. Since 2008, the US has not reported any further test or development work related to pulse detonation system.
“The exact reasons for the US leaving this project are not known. It is obvious that technological challenges are one reason. There could be a possibility that the performance of the engine may not have matched their requirements. TBRL's investments are expected to be based on a proper cost and benefit analysis,” Lele added.

Defence startups in HAL, BEL cross-hairs
MUMBAI, MAY 18:
Hindustan Aeronautics Limited (HAL) and Bharat Electronics Limited (BEL) are scouting for defence startups to build a culture of innovation. As the initial contributors to the ₹100-crore defence innovation fund, announced by former Defence Minister Manohar Parrikar, both HAL and BEL are seeking startups that will help provide small, low-cost military grade innovations to minimise imports and to help the country achieve self-reliance and indigenisation.
As technologies like artificial intelligence, robotics, drones, and advanced cyber security tools gather steam, the Defence Public Sector Undertakings (DPSUs) maintain startups in the defence sector, and early-stage tech companies as well as SMEs are well-positioned to contribute to the defence industrial base.
The potential is huge. Amit Cowshish, a former financial advisor to the Ministry of Defence told BusinessLine, that “unlike other sectors, startups in the defence sector have to contend with the fact that it is a monopsony. These startups have a tremendous potential, but they cannot expect to sell whatever they come up with unless there is a demand from the armed forces. The armed forces, in turn, cannot replace existing inventory as soon as new technology is developed by entrepreneurs.”
This leads to an impression that defence startups “are not getting as much encouragement as they deserve, which is not entirely correct.”
Briefing the startups
To amend the anomaly, and to provide a platform for defence PSUs and startups, 40 defence startup enterprises were invited by BEL and HAL recently to showcase their capabilities and to identify areas of partnerships in manufacturing as well as design, development and services. The aim was to help “create awareness on the opportunities available and to facilitate interaction between the bigger defence PSUs and smaller startups”.
Startups in the “defence electronics field and the aerospace sector were briefed about the stringent quality measures and reliability standards that were needed at every stage and the need to upgrade constantly,” sources said.As Chief Minister of Goa, Manohar Parrikar , has now also reiterated his interest in building technologies for the forces and earmarked funds for Goan startups in the defence sector. As Defence Minister in February 2017, Parrikar had announced the initiation of the defence innovation fund at the Aero Show in Bengaluru.
In Goa, announcing his plans to set up a Startup Promotion Board, on the lines of the Foreign Investment Promotion Board, Parrikar earmarked ₹15 crore to boost the startup sector in the State. Of this, “a substantial amount would be allocated for defence startups as Parrikar has vocalised his interest on several occasions. He had launched funds to build products for the Army,” said sources.

DRDO's Rudra M-II Missile air-to-surface missile (ASM) to break cover soon?
2 minutes
SOURCE: IDRW NEWS NETWORK
IMAGE REPRESENTATION OF NGRAAM
Earlier this year, idrw.org was first to confirm and report that DRDO (DRDO working on New Rudra M-II Air to Surface Missile (ASM) for Indian Airforce) has been sanctioned 489.06 crores to develop a new Air to Surface Missile (ASM) dubbed Rudra M-II for Indian Air force.
Recently DRDO has issued tenders which idrw.org has gone through which reveals that DRDO has invited bids to build an Aluminium container for R167 Article for storage and transportation of RudraM-II Missile.
Very little has been known about the missile since the Project approval for Rudra M-II Missile was only given last March (2016) by the government and looking at the speed at the missile development has been progressing it can be said that it will be similar to the new generation anti-radiation missile (NGARM) in design aspect which is under development.

BDL Introduced 2 new ATGMs, which off course will not be bought by Army. One 2800m range wire guided ATGM and a Radio guided ATGM. Might be one of those?

Wire guided ATGM? Are you sure? Because last time during NAG development, DRDO failed to produce one. If its true, then its a great news. Would be thankful if you could provide the link.
