The further, the faster: the US Army will test a new ramjet weapon

Thanks to a development company led by Boeing specialists, the US Army will test a new high-speed ramjet next summer. weapon... Boeing is developing the device, called the Ramjet 155, in collaboration with British defense firm BAE Systems and Norwegian ammunition company Nammo.

This is reported by the American magazine Breaking Defense, citing a source in Boeing.

The further it flies, the faster it moves, and this also helps it avoid detection.

- the representative of the developer company explained in simple words the principle of operation of the weapon.

While conventional rockets carry an oxidizer to burn fuel, a ramjet engine literally "breathes air." This means that it "digests" the air around it during flight. Since it does not need to carry the additional weight of the oxidizer, it is capable of flying long distances and also has unique flight characteristics that make it more tenacious.

According to Boeing project manager Dan Palmeter, the projectile will be ready for the first launch from the L39 cannon next year.

Other American companies are also developing ramjet engines. They are also working on such weapons in Russia, China, India.

What industry monsters are involved !!! And judging by the photo to the article, they are testing all this economy at Uncle Vanya's garage Or rather, on the contrary - Uncle Vanya in the garage has long experienced what industrial monsters are fighting over

And in general looks like a big blowtorch

It is the same everywhere, but where else can they be held? in palaces?

Marching ramjet: are on the Onyx and Mosquito anti-ship missiles.

[volodimer]

Exactly.
"Mosquito":

The rocket is equipped with a combined (sustained-through ramjet 3D83 engine with a built-in starting powder accelerator) propulsion system. The accelerator is placed in the nozzle of the main engine, after 3-4 seconds after the start it burns and is pushed out of the nozzle by the oncoming air flow.

The combined installation made it possible to significantly reduce the length of the rocket.

"Onyx":

The rocket consists almost entirely of a ramjet engine (ramjet), around and inside which the rest of the systems are located.

What's the big deal? It is not clear from the article why one should be surprised.

They stuffed this engine into the projectile. It should cost so much that few goals cannot be bought for the same money.

[Cananecat]

As far as I understand, this will be one of the types of high-precision ammunition, while tests in a static mode on the stand will give different indicators or do they imitate the intake of air mass by injection?

[voyaka uh]

Here's a little thing:

155 mm projectile with a supersonic ramjet engine. Flies 150 km.

Here's a little thing

Is this that (or a similar) thing, because of the cost of which, two gun mounts on Zumwalt were recognized as failures?

[voyaka uh]

Another shell was being prepared for Zumvolt:

But turned out to be as expensive as a cruise missile

[Kurare]

But turned out to be as expensive as a cruise missile

So shells / rockets with a ramjet engine are also not cheap.
Long-range air-to-air missiles, even at their high cost, are what you need. The same European Meteor costs almost a lemon Euro. But as an artillery shell ...

[rocket757]

Such an expensive babakha, should no longer fall into the window, but into the eye of a needle, so that at least somehow justify the costs of production and use!

[voyaka uh]

I agree with you.
KVO should not exceed 1 m so that such long-range projectiles pay off.
And the higher the speed, the lower the accuracy.
Since there is no time to make a correction.
Regarding the Karabakh war: a subsonic precision weapon produced a devastating effect, and a supersonic one - only noise.
(Including Israeli Laura).

[rocket757]

The economy of war! Nobody has learned to cancel it.
Victory, as it were, will write off everything ... but this is only said so, but in fact, if it is impossible to make up for the losses at the expense of the losing side, everything can happen very badly.

[rocket757]

Other American companies are also developing ramjet engines. They are also working on such weapons in Russia, China, India.

... Everything is correct! And this is very reminiscent of the anecdote about cowboys / two men who ate soap for FREE, for example, or something worse?
Nobody has such associations?

Since it does not need to carry the additional weight of the oxidizer, it is capable of flying long distances and also has unique flight characteristics that make it more tenacious.

I assume that we are talking about a kind of simplified mini-"Vanguard". This development will increase the firing range of the MLRS by an order of magnitude and at the same time increase the projectile speed ...

[voyaka uh]

No. It's just an artillery shell.
They have another development:
a mixture of Dagger and Vanguard.
Tactical BR is dropped from the plane, goes up (like the Dagger).
And there the glider is detached (like that of the Vanguard).

[Sergey Valov]

Zadolbal ignorance of the authors.
"High-speed ramjet weapon" - a weapon cannot be ramjet, a ramjet engine can be.
"While conventional rockets carry an oxidizer on board" is not at all necessary, rockets with powder engines do not carry an oxidizer , missiles with VRM do not need an oxidizer either.
"He" digests "the air around him during the flight" - the air is "digested" all WFDs.
"Since it does not need to carry the additional weight of oxidizer, it is capable of flying long distances, and also has unique flight characteristics that make it more tenacious" - an empty, meaningless phrase.
Not a word about the serious disadvantages of ramjet engines.

[Mwg]

I also noticed wooden phrases. It looks like a Google translation by a translator and after a bit corrected

[Aleksandr97]

The photo for the article is not good. There are tests of a turbojet engine.
Direct-flow motors, in principle, will not work under stationary conditions! We need an oncoming air flow - an oxidizing agent.
And what Dan Palmeter, Team Leader of the Ramjet 155 project, is talking about, is still artillery ammunition with an increased range of up to 44 miles. In addition, he will be able to lock on moving targets thanks to high-precision guidance and innovative homing technology. A demonstration of the new air-jet munition is scheduled for the summer of 2022. After testing, the developers will continue to work on improving the system's performance.
In the photo, the second with a ramjet engine.

The further it flies, the faster it moves, and this also helps it avoid detection.

Until reaching the speed of light.
