Grumman Rules the Sky

[J.A.W.]

What is it you don't understand about math... oh wait... I know... everything.

Look Baldy, - if you cant work out the relationship between time-to-climb & climb rate.. ..nevermind..

& I was gonna say, I reckon your film of beating down that B-26 was boss..

( & how's your p-factor capacity been lately, bit of constriction there, maybe?)

Why should I?  The record was time to climb.  Nothing else.

As has been said many times, any talk of FAI is irrelevant.

All that matters is the data from the test and the conditions of the test.

& Brooke,  just how do you suppose the Brits got their Meteor climb record on the books?

They applied to the FAI for it, of course - according to longstanding FAI protocols..
Having met the criteria, it duly went on the record..

& the USN didn't - despite what Widey so casually claimed..

Alright Mr Maths, what is the relationship between time-to-climb & climb rate - then?

Nevermind - since you have already got it wrong, that'll do..

[BaldEagl]

Alright Mr Maths, what is the relationship between time-to-climb & climb rate - then?

Not a simple answer as you have roll time invloved based on how the tests were timed.  I'm sure you considered this though right?

Once airborn 3 minutes to 10K = 3,333.333 ft/minute, to 20K it's 6666.666 ft/min but that's not what was measured so is irrelevent.  Give me the roll time and I'll give you the real answer.  You must know it since you know so much about this test.

BTW that's average across the climb.  Specific climb rates vary by altitude but you knew that.

[J.A.W.]

Nah, its really pretty bloody simple..

Greater climb rate speed/distance = lower time-to-climb figure - in seconds elapsed.. ( based on the mean, natch..).

[BaldEagl]

Greater climb rate = lower time to climb.  Agreed.  Speed/distance?  Please please please explain that to me.  I'm so awaiting your mathematical genious.

[J.A.W.]

Again too easy..

climb rate = TAS/AoA..

[BaldEagl]

Again too easy..

climb rate = TAS/AoA..

That has nothing to do with speed/distance.  I have alarming news for you; 350 mph/mile = 350 mph.  Duh.

And BTW, climb rate = ft/min unless you grew up on a different planet, which seems more and more likely.

As explained:

“The first mention of a 'time to climb' world record in our books was for a flight made by a British pilot onboard a Gloster Meteor on 31th August 1951.

“No performance set in 1946 could therefore have qualified as an official ‘world’ record, as this category of record did not exist then."

[Brooke]

Again too easy..

climb rate = TAS/AoA..

ROC = TAS * sin(climb angle).  Also, climb angle is not equal to angle of attack (AoA).  The two are very different things.  AoA is angle between wing's chord and aircraft's velocity vector.  Angle of climb is angle between velocity vector and ground.

[J.A.W.]

Brooke, no call to go all 'rocket science' on us, oh wait, what would the space shuttle do..

Ah that'd be somefink like 90 degrees AoA on climb out wouldn't it..

& when will you comprehend the FAI thing..

If you want to beat or set a novel ( new, not fictional) FAI/World record for virtually anything aviation related,
then approach them for the record ratification criteria..

As it happens - there were no supersonic manned flight records in the FAI book in 1946 either,
but that was gonna change too..

[J.A.W.]

& one more time..

If you DONT approach the FAI for ratification of your 'record', whether a never before attempted one,
 or one that has been contested for a century or longer..

It WONT be official, & WONT appear in the FAI records list, obviously..

& therefore it WONT be acknowledged or even officially EXIST..

Of course the RAF Record Flight were cognizant of these facts..

& ensured that the proper approach to the protocols was made.. & got the record, officially in the FAI books..

[Brooke]

& got the record, officially in the FAI books..

That has nothing to do with a 1946 Bearcat test.

[J.A.W.]

You've got that the wrong way 'round Brooke..

A 1946 USN airshow stunt has nothing to do with an officially sanctioned FAI World time-to-climb record..
