View Full Version : P47 diving at 1400kph?

I was reading an interview with Guenther Rall
http://www.historynet.com/air_sea/aces/3038146.html?page=1&c=y
Really interesting to read (and a lot of other interesting stuff on this website). But one thing baffled me in the interview. It was about the opposing fighter aircraft:

"The P-47, which as you know shot me down, we knew right away. It had tremendous diving speed and could run up to 1,400 kilometers per hour, where the Bf-109 was limited to 1,000 kph. I learned this quickly when they chased me..."

Diving speed of 1400KPH??? Isn't that a bit optimistic?

That's a sure way to break the Ground Barrier.

Either a typo or a case of blurred memory. That simply couldn't happen.

Actually it is an error but a gauge error. This increases with pressure change . A typical ww2 gauge problem. High pressure change results in wrong readings mostly happens closing on mach.

I was going to say, isn't that past the speed of sound?

It turns out, I have much first-hand experience with this in IL-2.

It ties with my development of diving tactics on well defended airfields in jabo attacks, tactics which earned the name, "Boom and Broom"

Yes, even on a cold winter's day at the Dead Sea http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

I can go well above 1000kph in several IL2 fighters.
At alt.

Spot on! Hence a Mach Meter....

Perhaps the numbers are off, but the principal is correct. http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

Is it me, or does that 109 G6 cockpit look "spacious" in this picture? http://forums.ubi.com/groupee_common/emoticons/icon_eek.gif

could it not simply be a case of mis-calculating? Maybe the speeds got changed from mph, to knots, to km/h and making a few errors along the way seems logical.

Sounds like somebody mixed up knots and kph.

He kind of looks like he's busting a fart in that cockpit when the picture was snapped.

It's true.

In fact, many planes had wings that were designed to remove themselves at high speed to allow supersonic flight.

Also, did German pilots sit on their 'chutes also? He's not wearing any bulky flight gear either. The condition of the pit is a factor too. If it's being restored, instruments, panels and sections could be missing.

Optical illusion. He's got one arm hanging out leaving more room for his body. Ask him to put both arms in and take another picture. He might refuse since he can't be as slim as he was back in the day. http://forums.ubi.com/images/smilies/16x16_smiley-very-happy.gif

I was lucky enough to sit in a wingless Bf-109 at the West Houston Airport in the mid-eighties. Property of the Confederate Air Force. I only weighed 145 lbs. then and the thing felt as tight as a race car.

He also did a great interview that came in the "museum" portion of Janes WWII fighters. IIRC, Bud Anderson did the USAAF portion.

They may be on Youtube, if not, I may post them up there.

I guess there is no conversion fault from knots into mph or kph. Speed gauges in german aircraft tend to be calibrated in kph anyway.

Nice picture you have there Cawimmer!
