Ok - now we have the inflight "computer" that will give you a mach readout......

I challenge one of you brave pilots to break the speed of sound.

To be a sucess:

You must film / record your attempt....

You must not loose control of you aircraft....

You must not die.

pls have the e6b up in view when recording film or take a screenshoot.

Best that I've done is Mach .83 - straight down in a fw190d9

Is the film viewer working?

So what you're really asking us to do, is to find a bug?

Waffle · « **Reply #4 on:** February 29, 2004, 05:24:17 PM »

nah - no bugs - just see if you can do it...lol

guess take sceenshots if film not working

If flight modeling is correct it cant be done with WWIIprop driven aircraft.
Well if can but you cant retain control of the aircraft.
If memory serves correct it has something to do with the rear elevators.

you guys missing the point....lol - how fast can you go???

guess we'll have to modify the rules....

how fast can a wingless lawndart go???

I want to see speeds posted..not "reasonable" thinking......lol

Ok you only need to get rid of two rules
Loosing control of aircraft,
And dieing.

Well you could always bail I suppose

Just take a p40... you can do it..

unless: they fixed it...

well i tried and only hit .8 but i lived!

Woohoo! Mach 1.01!

Procedure:
1. Start 262 on auto climb
2. Take a nice shower
3. 262 is now at 34k
4. Nose straight down at full throttle
5. Smack alt-s when the time is right and idle the throttle
6. Carefully use elevator trim to recover from dive

if anyone actually broke the sound barrier in WW2 it was most likely a German pilot in the Me262.

It would be interesting if the modern replicas could be used to validate the pilot's claim.

WWII planes CAN (and could) do mach one (though only in a dive) this was demonstrated in several post war (but with WWII planes) airshows in which pilots would break the speed of sound to show off.

So the extreme buffetting and loss of control the X-1 experienced was because it's design and the prop jobs had a better design? Not sure how a WWII aircraft could accomplish this. Do you have any references to this I'd like to read up on it?

A prop job going from subsonic through transonic to supersonic just seems a bit odd to me. Especially considering the X-1 had to adjust improperly placed horizontal stabilators to overcome the extreme buffetting experienced in the transonic and super sonic speeds. Can a prop even withstand the oblique shock waves it'd be put under in such circumstances?

Oh and if WWII prop jobs could accomplish this we need to start rewriting the aviation history books as to who and what aircraft broke the sound barrier first.

Prop planes cannot break the sound barrier. The faster you go the less thrust you get fropm the prop and the more drag. When diving props get to the point where the propellor is effectively a big airbrake on the front of the aircraft.

The only things that could, conceivably, have done it in WWII are the Me262, Me163, He162, Meteor Mk III, P-80 or the MXY-7 Ohka "Baka".

Personally, if it was done, I'd put my money on the Me262.
