MBDA Meteor

[mapuc]

Had a look at the weapon in the Command and toke a look at Meteor. It was there but with some failure

The distance this missile can go is not 75 miles it is about 200 + miles

I have in some swedish newspaper read that this Meteor is now a permanent part of the equipment(I'm however not sure. And now I can't find this article.) I know they had a great success trying it in automn 2013

Thanks for the heads-up Markus, but that cannot possibly be right. Assuming a fuel fraction of 40% that's 74kg, and it seems unlikely this amount would propell a 110kg body 320km at a max speed of Mach 4 and arrive on target at speeds well above Mach 1.

The source of the information is the AMRAAM's no-escape zone. Seems someone just multiplied the max stated range of a late-production AMRAAMs and came up with 200nm. But this is not the right way to do it. Uhm yeah and max range and no-escape zone is not exactly the same thing hehe.

The Meteor has about three times the sustainer performance compared to a conventional rocket motor. Simply put, this means if the sustainer on the ARAAM runs for 20 seconds, the Meteor can run for 60 sec. When the fuel is out, both missiles will glide and deaccelerate in pretty much the same way. The extra 40 seconds on sustainer for the Meteor will not take it 125-150nm further.

In any case we've done most of the research for a new propulsion model for Command that will improve things quite a bit and make the advantages of the ramjet motor clearer.

Thanks

Mach 4 for 40 seconds (not including deceleration) is about 52 km (32 miles).

The airbreathing motor has more air resistance, less volume used for fuel and more complex structure though.

It only fly that fast when it has found its target. the missile has a two-way link to the fighter jet.(JAS39, has)

the propulsion is all using integrated rocket/ramjet propulsion(from same link about the missile)

what I understand it will use this ramjet until a few miles before the position of the target thereafter the rocket will kick in and the missile will increase rapidly in speed before hit.

The distance this missile can travel is not something I only have read on wiki-pages have also heard about in Swedish news program some years ago.

about the Meteor on JAS39 I found this information from FMV(Försvarets material verk=Swedish Defence Materiel Administration)

"During the fall, further work to be carried out in order to have the final delivery in 2014 Gripen will be the first aircraft is operating with the Meteor missile"

Forgot something

There seems to be a problem with the link when you click on it you don't come the wiki page I copied. I don't know why

Here is what to do, if you didn't know

When you have clicked on the link you come to a different wiki page and there you can read "Did you mean: Meteor (missile)" click on the word Meteor and you come the right page.

The rocket is the booster and the ramjet is the sustainer. Seems the weapon can throttle back to save energy for the end game, but not sure if it can shut down and restart the ramjet engine for long-range shots.

A restartable rocket motor was planned for one of the AAAM compeditors before that program got killed in the early 1990s. Pretty interesting stuff (if you're an engineer at least) but that is not something that Meteor uses. Python 5 can supposedly control how fast the fuel burns too, to prevent it from going too fast and overshooting when being fired over the shoulder.
