Exceed Mach 3 Award.

Featured Replies

Looking through the possible awards list and paused at the exceed Mach 3 award. My imagination fails me at coming up a small, light plane of the type flight favors that could reach those speeds. Any ideas?

We are all connected..... To each other, biologically...... To the Earth, chemically...... To the rest of the Universe atomically.

Check the Maule thread. If you have the update, maybe if you pull the RPMs back enough.... :-).

With a not too steep dive in the P-51 from maximum height its possible...

In reality the plane would have broken down into pices ... but not in flight...

Were talking a 40 degree or something dive from 40´000 feet or so ...

With a not too steep dive in the P-51 from maximum height its possible...

 

I'm guessing it's not, not even with a 40-degree dive from 40000 feet. To try to get a F-9 Cougar (http://en.wikipedia.org/wiki/Grumman_F-9_Cougar) supersonic, one had to climb to FL370/380---which took quite a while---then roll inverted and push forward to zero-G, maintaining full power all the while. The nose would float downward until the a/c was pointed straight down. One would then hope to see the mach-meter pass the magic number before realities of recovering without pulling the wings off intruded. If mach one was tough for the Cougar, mach three is out for the Mustang.

I think either plane would simply melt, if the structure somehow remained intact.

If you read Chuck Yeager's autobiography, which you should incidentally, because it is great. You'll know that the Bell X-1 was stressed for 18G, and it had to use the trimmer to move the elevator because the shockwaves when it got near Mach .9 were right on the elevator, preventing it from being moved.

 

Some years before the X-1 managed to pass Mach 1, the British were conducting steep dive tests in WW2 fighters, and the compressibility and shockwaves on the controls was preventing them from managing it. They developed a tailless delta to try it, and gave up when Geoffrey deHavilland jr was killed in it as it disintegrated when approach Mach 1. There is no way a WW2 fighter should be able to pass Mach 1 intact, let alone Mach 3.

Easy:

  • Get up to max altitude.
  • Detach the wings.
  • Scream really loud.

:biggrin:

There's no place like this place, so this must be the place.

I finally managed to break mach 1 in the P-51 a couple of weeks ago. Assuming you can get it high enough you should be able to get it to mach 2 (Once you break the sound barrier it becomes much easier to speed up so if you can crack mach 1 you should also be able to get mach 2 if you have enough fuel and/or altitude to do so!)

Well at first I was thinking they might go for an X-15, but then figured that would be too complicated, since it needs to be dropped from a plane. Then I figured SR-71.....

 

But since that's way too fast for the limited area of the game to be of regular use, it occurred to me it would probably have no cockpit.......

The only other non-rocket plane that will get there is a MiG-25 (at least that has been publically acknowledged). I doubt that would have a cockpit if made either.

 

I don't know how far an SR-71 would get at Mach 3 from a take-off. I stand to be corrected, but I was under the impression they took off and tanked again from a KC-135 before getting too carried away with the high speed stuff. Of course that could have been because they could, not because they had to.

There is also an aero-cache at about 85,000 feet. It is a record height from the SR-71, above Honolulu airport. I guess both at there to hint at future updates. Only Mach 1 is an acheivement with a gamerscore, though. You can get the P-51 to Mach 1 in a straight dive, don't know if it'll go Mach 2, but I didn't.

Superman breaks Mach1 only about 200 meters out from the elevator shaft, only took him like 4 seconds. Although...the sonic boom that he produced, would that happen if you have no engines to produce sound?

Yes. Gliders make a lot of noise without an engine.

I think it has a lot more to do with the displacement of air than with engine noise.
