India all set to trial supersonic cruise missile BrahMos on Wednesday


BHUBANESWAR: Finally the D-Day arrived. The aircraft is ready and so also the missile. India is all set to conduct the first trial of supersonic cruise missile BrahMos from Sukhoi-30 MKI on Wednesday.

Defence sources said the aircraft will take off from an air force base in West Bengal and fire the missile against a target over the Bay of Bengal. Preparation has been completed for the maiden trial.

Initially, though it was planned in 2015, the test was deferred due to delay in integration with the aircraft.

"The launch window is 10 am to 12 noon. Two aircraft have been kept ready. While one has been integrated with the missile another will track all along its flight - from fire to hit. We all are excited for the mission," said a defence official from New Delhi.

Jointly developed by India and Russia, the air force version of 8.4-meter BrahMos missile, fastest in the world, has a strike range of 290 km and carries a conventional warhead up to 300 kg. With high-precision, it has devastating power at a supersonic speed of Mach 2.8.

Defence sources said the BrahMos Aerospace had to reduce the weight of the missile as it is to be launched from a moving platform unlike its army and navy versions. Some modifications have also been made in its design to easily integrate it in Sukhoi aircraft.

Though the air-version of the missile is yet to be tested, several countries had evinced interest in the weapon system during the recently concluded Dubai air show. Earlier, it had demonstrated successful integration with the aircraft.

If test fired successfully, BrahMos will be first weapon system in the world to have such capability. As of now, there is no such weapon available which can be fired from land, sea and air platforms.

Wonder why Russia did not create an air launched version of Yakhont / Onyx or do they have one?
Is this capability important enough for Russia to induct Brahmos?

They have the bigger Kh-22/32 which has top speed of mach 4.5-5 and use Tu-22Ms. which carry 3 of these for the same role. IAF does not have anything like Tu-22M3 so it wanteted an Air launched Brahmos. Brahmos-M is the real game changer as Su-30 can carry 3 of those.

DRDO lab developing booster propellant for BrahMos missile
Final tests to be carried out next month by city-based lab

A solid propellant used as booster for the BrahMos supersonic cruise missile, which was successfully test fired from a Sukhoi-30 fighter jet on Wednesday, is being developed by Pune-based High Energy Materials Research Laboratory (HEMRL) of the Defence Research and Development Organisation (DRDO). HEMRL Director KPS Murthy, who was speaking to reporters on the sidelines of the inauguration of the 11th International High Energy Materials Conference and Exhibits (HEMCE-2017), made the announcement on Thursday.

Murthy said, “A solid proponent booster, which is an important component of the BrahMos, is in its final stages of development. The requisites, which have been conducted in the recent past, have shown positive results and a final test, called mechanical vibration test, will be carried out next month. The propellant will thereafter be put to use in the missile.” The test of the BrahMos missile on Wednesday is important as it has made the missile capable of being fired from land, sea and air. The supersonic missile, which has a range of 300 kilometres, has been developed and manufactured by BrahMos Aerospace Pvt Ltd, a joint venture between the DRDO and NPOM from Russia.

HEMRL scientists said that indigenously manufactured fuel will make the production of the missile much more cost effective. The three-day conference that began on Thursday is focused on insensitivity munitions, which are developed to withstand extreme conditions and Green Energetic Materials, which are explosives and propellant with the least pollutant emission.

Murthy added that the HEMRL has developed two green explosives that are in the final stages of testing and will soon be put to use with the armed forces. He said that in the days to come, the defence establishments will have to focus on green technologies to minimise the pollution and footprint created during manufacturing, testing and usage. V Udaya Bhaskar, Chairman, Bharat Dynamics Limited (BDL), which is the key missile manufacturing PSU of India and PK Mehta, head of Armament and Combat Engineering of the DRDO, were also present.

Kh22 is a very different missile - liquid fuel rocket engine and flies at very high altitude.

Brahmos engine (liquid fuel ramjet) is Russian crown jewel. No country has that tech and Russia will not share that with anybody. Asking for that tech will deteriorate India Russia relations.
Seeker and booster we can make without issue.

There is nothing particularly secret about a ramjet. It is in principle the simplest jet propulsion type. The only reason only the Russians use it in significant terms is because of their specific Cold War need to penetrate the US Navy's defensive net around the CBG with very long range and high speed missiles carrying massive warheads designed to disable Capital assets (aircraft carriers) in single or two hits. No other country had need for this specific capability so nobody pursued development until recently.

We have the Akash- but it's solid fuelled - which is much simpler.

XASM-3 is solid fuelled.
YJ-12 uses Kh31 technology - China had Moskit and Kh31 missiles
HF3 is interesting - as Taiwan never had missiles to reverse engineer.

The world's first ever operational "missile" the V-1 was powered by a liquid fuelled ramjet. True it wasn't supersonic but it was made at a time when principles of supersonic flight were only beginning to be investigated. But again the basic design of a liquid ramjet is absolutely nothing exotic

V-1 used pulsejet.
Ramjets and Scramjet are conceptually and mechanically simple (no compressor or moving parts) but complex aerodynamically.

 

[Vorschlaghammer]

The dreaded V1 buzz used to be nightmare fuel for Londoners. As long as you keep hearing it as it passes, you're safe. If it stops, as you hear it, you could be in the next victim list.

 

[Vorschlaghammer]

And @Kay is right. Ramjets are operationally simpler, but need to be carefully designed. A well designed ramjet has no turbine inlet or valve temperature limitation, no maximum compressor blade speed restriction, and will just keep accelerating, until the design limits of the intake, combustion chamber and nozzle are reached. In fact the design gets harder the higher the max speed goes. After a certain point of increasing airspeed numbers, "turbo" engines are no longer useful, and ramjet is the only answer.

From Wikipedia:
"Turbomachinery-based engines, while highly efficient at subsonic speeds, become increasingly inefficient at transonic speeds, as the compressor fans found in turbojet engines require subsonic speeds to operate. While the flow from transonic to low supersonic speeds can be decelerated to these conditions, doing so at supersonic speeds results in a tremendous increase in temperature and a loss in the total pressure of the flow. Around Mach 3–4, turbomachinery is no longer useful, and ram-style compression becomes the preferred method.[1]"

A Ramjet is any jet engine that uses high speed aerodynamic characteristics to force or "ram" outside air into an intake, and further down into diffusers and combustors. The typical old-school Ramjet intake uses a shock cone which helps the intake pressure recovery by creating oblique compressive shock waves at supersonic speeds, and slows down the intake air to a more manageable subsonic level for combustion. (MiG-21 has it too, to create subsonic high-pressure airflow for the turbojet to use)

This P&W J58 is an interesting middle ground, where it has a turbojet core and a shock cone in the front with flaps to vary bypass air around the core. At low speed the flaps are closed and the turbojet gets the majority of air and creates thrust. As airspeed increases, the amount of bypass air is also increased until it reaches it's top speed where the majority of air received from the ram intake bypasses the turbojet core, and gets burned in the afterburner combustor, basically like a ramjet. This enabled the SR-71 to fly at a "sustained" airspeed of Mach 3.2, not the "dash" speed of MiG-25.

Even the chinese have tried their hands on this type.

A scramjet is a type of ramjet that typically operates in excess of mach 4. At this tremendous speed, tasks like intake pressure recovery, flame holding, combusting are exponentially tougher, because the intake can't slow down this super-fast airflow to subsonic; best it can do is to lower it to a lower mach no. so the combustion has to happen in a supersonic airflow. Trying to further slow down this much high speed air will increase temperature and pressure loss to an impractical level which our current materials can't handle. Even then the current research prototypes have to use active cooling and special fuels to maintain operation.

At the end, it should also be mentioned that all Ramjet engines need a separate booster before it can contribute thrust, it can't operate at 0 airspeed.

pakis in panic mode just released hafeez saeed from house arrest. They are worried that Modi may order the next test on this fat a$$. Question is how long will it take for Brahmos cruise missile to reach this fatfawk's house once its fired far from border.?

The point is: there is nothing special or unique about this engine anymore, American and Chinese have already got this technology. Both of them don't need Russian to share this. As long as Russian sold the missile to them, the technology is not unique anymore.
By the way, Taiwanese missile is based American BQM-163 which was developed from KH-31.
