Maiden tests of air-launched BrahMos from November

[Gessler]

Yes LRCM was proposed to be tested in 2014. Do not know what happened since then. Do you have any idea of Multi target missile which was planned to be tested in 2014? It was a missile with small glide bomb type of small warhead which shall glide to the target after release from mother missile.

Sorry, not aware of any such developments. Knowing DRDO, it will probably emerge sometime next decade.

Man I quoted Wikipedia here u can read if you have any link to support yours then you are welcome

https://en.m.wikipedia.org/wiki/Ramjet

You are second after gessler to make such a statement and want to prove Wikipedia wrong but ok give me a link.

Ramjets always slow the incoming air to a subsonic velocity within the combustor. Scramjets, or "supersonic combustion ramjet" are similar to ramjets, but some of the air goes through the entire engine at supersonic speeds. This increases the stagnation pressure recovered from the freestream and improves net thrust. Thermal choking of the exhaust is avoided by having a relatively high supersonic air velocity at combustor entry. Fuel injection is often into a sheltered region below a step in the combustor wall. Although scramjet engines have been studied for many decades, only recently have small experimental units been flight tested and then only very briefly (e.g. the Boeing X-43).[15]

As of May, 2010, this engine has been tested to attain Mach 5 (1,701.5 m/s; 6,125 km/h) for 200 seconds on the X-51A Waverider

From your very same wiki page, please read your entire link, a scramjet is a ramjet that can take super-sonic air-in flows EXACTLY what I said, that is not the type of ramjet you have on Brahmos.

what you have on Brahmos or Yakhont a liquid fueled is called a integrated ramjet rocket, look go to page marked 38 (or 12 if you want to count) and see all LFIRR based ramjets, none have reached above 4.5 M even in experiments. All are below 3.5M except US navy GSSCM which remained experimental and was quarter of the weight of Brahmos.

Is it possible, who knows maybe someone can make a design that can slow airflow for this engine, but as of now I don't think it can go to 5 Mach.

No, dude. Ramjets can indeed go upto 5 or 6 Mach, if they're actually designed & certified for that threshold (the BrahMos/Yakhont Ramjet is not).

Scramjet is an entirely different type of engine. The major difference is that a Scramjet has no moving parts and it can sustain speeds well upto 15 Mach or more, again depending on design & specified threshold.

Even normal ramjets don't have moving parts, scramjets are just a variant of ramjets. The sub-sonic comustion ramjets that can take speeds upto 5 mach are generally solid fueled like mica

The basic ramjet engine consists of an inlet, diffuser, combustor and exhaust nozzle (Fig. 1). The inlet collects and compresses air and conductsit via the diffuserto the combustor at reduced velocity thereby developing ram pressure and an elevated temperature. The combustoradds heat andmassto the compressedair by the injection and burning of fuel. Finally, the nozzle convertssome of the energy of the hot combustion productsto kinetic energy to produce thrust. Because the ramjet depends only on itsforward motion to compress the air, the engine itself has no moving parts and offers higherMach number capabilitythan turbojet engines.However, unlike a turbojet or rocket engine, the ramjet requires an auxiliary boost system to accelerate it to its supersonic operating regime.

I am talking about this.

Erm....nope. M3.5 is about as fast as BrahMos-NG will go.

After this, all R&D regarding Ramjet cruise missiles will be severely curtailed - limited to electronic enhancements at most. Because after this, the BrahMos-II with the Scramjet will come in both ALCM and ground-launched versions, with ship-based variants also available.

It is said that even the proposed Ramjet-powered LRCM (600-1000km range at max 3.2 mach) has been put on the back burner and maybe even cancelled because of the emergence of BrahMos-II proof of concept in Russian scramjet developments.

Actually LRCM should not be a big technical challenge as Brahmos engine was supposed to be used in same.

@Gessler Sorry minor edit I meant to say like Meteor missile, just noticed.

Desi mator like Ram propelled A TO A missile is in making.

Big Thumbs up. Earlier it was announced that it will happen in 2014 end. Now it is happening after 3 years. Anyway, this is a deadly punch and a great combo and a giant leap in sand off capability.

@sayareakd, how can you say that Brahmos air launched version will have 5000 kms range? Please elaborate.

Plane range + Refilling + Missile range=5000 Km
