Title: Dive!
Post by: Slade on August 02, 2012, 08:54:33 PM
Hello all,

Which fighter plane dives the fastest from 10k?

That is, if you take all the planes in the game which would reach the deck first...and be able to pull out just before hitting the ground.


Thanks,

Slade  :salute

I don't know about the fastest but planes that dives extremely well and retain their energy would be:

Ta-152
P47s
P51s
Tempest (strangely, you actually have to trim DOWN if you want to keep it in a dive)
La-7
190D
F4Us
F6F
Brewster

Most of these planes are rather heavy, meaning they act like a pendulum and swing straight up. Some just have very powerful engines that let them climb straight up.

The Ta152 will keep it's energy for a very very long duration after a dive. It bleeds speed very slowly meaning you can sometimes out sprint planes that would be faster than you in a level chase.

Brewster does not dive that well.

Can't speak to most on that list, but the Mosquito Mk VI leaves the La-7 in the dust.

 The US plane sets all dive pretty well. I like the P-51D best for diving and at 30.000 feet it is about 30mph faster than the Tempest in level flight. Also in a dive with a Tempest the 51 is faster if the pilot of the Tempest does not know to set the trim tabs for a dive. Other wise the tempest starts to pull itself s up from the dive just at the wrong time. The P-51 is a tough plane and you can fly it like you stole it and it don't come apart.

I reached almost 500 MPH from 15k in a p51

the 190a8 is one of the fastest divers , can go 600mph without a squeak.

No, but it retains its energy extremely well.  :noid

A bit too well perhaps?   :noid

But I found that it doesn't hold onto it's E that well. The couple of times that I flew it, after 3 or 4 BnZ passes, I found that you either had to dive away from the fight (extend, climb, come back) or else you start floundering and drop from your initial altitude quickly. If it had a stronger engine (like the Dora), you could zoom straight back up. But as for the dive itself, I agree, it holds very easily in a dive and the controls are very stable.

P-47M or N and F4U-4 are Monsters in a dive. MONSTERS!

They are spherical monsters - monsters any way you look at them!

It shakes and buffets at 600 mph and you need elevator trim to get it to climb again but yes, it's among the fastest in a dive.

But I found that it doesn't hold onto it's E that well. The couple of times that I flew it, after 3 or 4 BnZ passes, I found that you either had to dive away from the fight (extend, climb, come back) or else you start floundering and drop from your initial altitude quickly.

You're talking about reversing 3-4 times.  Why would you expect to retain E after that in anything?  One, maybe two passes easy on the reverse and it will get back to alt just fine.

P-47s have huge dive acceleration, however, they get into compressibility at a lower speed than the P-51s, F4U, F6F or 190s.

P-39s dive very well. They will lose ailerons and rudder at 595 mph. P-40s used to dive well, but now they shed control surfaces at relatively low speed. P-38s begin to compress at Mach .65 and are fully into compression at Mach .68. 109s stiffen up badly at high speeds, but that's not compressibility until well over 500 mph.

The Soviet fighters get into compressibility at around Mach .76, with this being a bigger issue for the La-7 due to its acceleration. The Yaks handles better at high Mach than does the La-5/7.

Spits can dive fast, they just don't accelerate as quick as the heavier aircraft. The Tempest dives very well and has by far, the best dive acceleration of any prop fighter (can't understand why, though), but the Typhoon gets into compressibility at a lower speed, comparatively.

Unless the Zeros have changed, the A6M5 dives better that the A6M2 as the latter will roll right and shed parts sooner. In fact, I've seen 578 mph TAS in the A6M5, without damage. I can say in confidence... That's not correct. The Ki-61 is a sterling diver, but slow to accelerate. The Ki-84 stiffens up badly at higher speeds and loses elevators easily.

Of all of them, the F6F-5 is the best diver, IMHO. Why? It can match just about everything and with combat trim on, will pull out of a Mach .80 dive hands off without pulling off power. It must be trimmed nose down not to do this. Just about every other fighter requires pulling back power to help trim out of 590-600 mph dive. Not so the F6F-5.
