Is it a true homemade trailer or did you buy one that did not have a title?

Only a matter of time before someone makes an ill-informed remark about Global Warming :wink:

But I can put a stop to that... :D

Why, I'm rather enjoying this exchange :)

Correct. But it's a slight tweak that would extend the effective range of current AMRs by as much as 50%, possibly more, and eliminate the uncertainties of long-range shooting caused by wind and atmospheric pressure. At 2000+yards, you're having to compensate not just for wind speed and direction, but for high or low pressure, and even humidity. This round eliminates those factors from consideration. That's not a slight advantage, it's a game changer.


Why not just automate the whole platform then.

Image

Just feed in the weather and target data and let the machine do all the work :)

If the guidance system is able to to stand up to firing stresses when it's this miniaturized, then up-sizing it for use in artillery is child's play. Tank rounds... it's a toss-up as to whether it would be worth it. The M1A1 already uses kinetic rounds that are accurate to a few inches at any reasonable engagement distance. With the incredible targeting systems used by an M1A1, you wouldn't gain that much in terms of accuracy or effective range, so the extra cost of guided rounds probably wouldn't be justified.


The M829 APFSDS round is still hurtling along at 4500 fps after travelling 5 kilometres, it won't be lacking energy at longer ranges.

Fired at a 10 degree angle, it will range to 29 kilometres, maximum range is a mind blowing 113 kilometres - surely such rounds would benefit from guidance.

The thing is, a lower-velocity system would simply be less effective in the roll of an AMR. That high velocity is exactly what allows a round as small as the .50BMG to be effective against light armor vehicles. A .50 AP round will go through an inch of steel easily, and still have enough energy to cause damage to engine parts. A larger, slower kinetic device might give you the same impact energy, but it won't penetrate as well as a smaller round at higher velocities.


Can't argue with that, velocity is an important part of penetration. There are however other very important factors in the equation such as sectional density, projectile shape and projectile hardness. For example, given the same 600 ft/lbs muzzle energy, I'm sure a modern kevlar helmet would successfully stop 45 ACP round, but I'm willing to bet that a pointed steel dart, 0.50" diameter and weighing 200g and travelling at 300 fps would make it through.

Don't forget that a simple lump of concrete dropped from altitude and precisely guided can very easily knock out a tank ;)

One AMR which I'm sorry hasn't been introduced is theSteyr IWS 2000. It essentially fires a miniature tank round that can penetrate over 1.5 inches of RHA at one kilometre.

Image

If they can make a guided version of that, brilliant :D

The round these guys are working on might be as large as a 20mm cartridge, but I highly doubt it. judging by the size of hte bullet itself, I would estimate they'd need about half again the charge of a .50BMG round to get the same velocity. You could get that by either increasing the diameter of the .50 brass by about 3/16", or by extending it about an inch. Recoil from the larger round wouldn't be an issue with the proper muzzle break, or even a back-blast system like the Croatian RT-20 20mm Hispano rifle. The 20mm Hispano round fires at 2800-2900ft/s, right around hte same velocity as .50BMG M2 ball, but the bullet is several times larger. The rifle is a bit primitive, but still easily man-portable and shoulder-fired without stressing the shooter unduly. So something the size of this guided bullet wouldn't be a problem


Truvelo and Denel both make conventional 20mm rifles that seem to work just fine, no need for a large backblast giving off your position.

Again, I agree - they could make a guided bullet for that, great. But such a rifle would have its disadvantages.

I still envision something that looks like a longer version of the M79 (tacticool of course, none of this wooden stock nonsense :D) firing a heavy streamlined round at high subsonic velocity. The rounds would be cheaper, and by virtue of their slower speed, more accurate. The launcher would be lighter and easier to carry and fire, and would have very little launch signature. Since it would be fired at a high angle and precise aiming would not be required because of the guidance, it could look as simple asthis. By virtue of its lower cost and lighter weight, more combatants could carry it. It would be effective against personnel and light material targets out to several kilometres, and would have HE and HEDP head options for dealing with area targets and light armour.

I'm not familiar with this argument but it appears to come from Tim Curtin, a denier spreading it around on climate change sites. I can't seem to find any published peer-reviewed articles by Tim Curtin hmm...

That coupled with a self-promotion website makes it pretty obvious he's a typical denier (usually applies to anything from evolution to the holocaust to climate change) stirring trouble. If he is actually right, he can go get it published in a science journal.

As for the equation itself, I'm by no means anywhere near qualified to answer it but from my understanding doesn't that only apply when you have enough oxygen on the LHS of the equation? If you don't have enough, combustion can produce other things like carbon monoxide? Also, studies are starting to show that there is a positive feedback between CO2 emissions and water vapour, so the water vapour produced on the RHS of the equation isn't as good as it sounds.

I haven't done chemistry in any form (high school or university), my understanding is flawed and I'm ignoring the mantra "I would prefer to be the last person who gets it right than the first who gets it wrong" but I thought I would comment anyway.

I find it hard to believe thousands of climate scientists would purposely ignore this equation if it would put an end to global warming without any form of conspiracy or reason to do so. You get paid a helluva lot more to be a climate denier. It would be logical for me to trust the field of climate science over Tim Curtin, whoever that is.

Dude... it's the combustion of propane! I was just showing that you're part of the problem, not the solution :)

Hehe this could be taken very wrongly :D

Black sounds better... which is more traditional though? Also, have you received your package yet? Been a while since I sent it now...

I figured the propane part (reading Spudfiles teaches you some chemistry) but I couldn't follow what point you were making. Now the 'genuinely' part is starting to make more sense :D

The point is that people generate CO<sub>2</sub> just by friggin' breathing. If you presented people with a list of things they have to give up in order to truly reduce their *cringe* carbon footprint to a level that would actually make a difference to the planet, there would be a lot more skeptics out there.

Mitchell and Webb make a good point, this is the idiot sort of denier:

[youtube]http://www.youtube.com/watch?v=mxXiZB5i8pc[/youtube]

... but there's another sketch (which I can't bloody find and I don't have the time to trawl through all three series) where "average guy" asks "scientist" how much stuff we have to give up and how much we can keep in order to make a difference, the ultimate point is that if you have to give up too much, life wouldn't really be worth living.

booooo... maybe it looked suspicious and they didn't want to send it by plane?

I got your point after your last post :D

Can I just say *phew*, was a little worried a climate change argument was going to break out. Someone just recently kicked up the Creationist thread on Theopia so I'll want to focus on that :D

That video reminds me of my parents. I have a feeling they take that line of reasoning, a lot easier than actually trying to understand the science I guess.

To be honest, I am personally sceptical on how much humanity can influence the climate, loath the fact that goverments worldwide are using environmental policy as an excuse to syphon off more taxes and, on an egoistic personal level, don't care much for the planet beyond my lifetime.

This is one (NSFW worded) environmental policy I can embrace though:

:D

Also:

I was walking home when a woman lost control of her pram and it started rolling towards oncoming traffic.

Realising I could help and panicking like hell, I asked myself 'What would Jesus do?'

So I quickly remembered that cars were invented in the 19th century and just walked away looking confused.

This is basically what I say to EVERY single person who asks me to donate to a good cause.

Disease is not a problem.

Hunger is not a problem.

Keeping everybody alive and well is the problem as we are already overpopulated.
Stop trying to help.

Imagine every baby on this planet being kept healthy untill they're 100 years old.
None of them infertile.
None of them too poor to get a nice lamborghini.
Everybody living in peace.
No more murders or accidents.

How long will it all last?
Lennon was a dreamer indeed.
