Grumman Rules the Sky

& to maintain  climb speed in a headwind you increase Angle of Attack..

No.  You don't.

I apologize.  I had thought, from your prior posts, that you had flown planes.  I've sort of been making fun of you, and I shouldn't.  So I'm sorry.

See Rule #4

[J.A.W.]

Or 'logically'  - has anyone here got access to a decent simulation program..
.. which can accurately factor in the known parameters.. & fly the stunt?

[J.A.W.]

If speed x A of A = lift..

& speed is a factor of thrust minus drag..

& climb speed/AoA ratio  is lift, then 'free' airspeed from a headwind of ~40mph at steady A of A..

Must 'logically' increase rate of climb.. No ?

Or, increased AoA @ steady speed [ extra thrust from 'free' headwind] = quicker climb..

[BaldEagl]

If a headwind really mattered then the FAI must have headwind parameters specified for each record, particularily time to climb.  If so, those paramaters have to be public, otherwise no one would know if they'd set a legitimate record or not.  Show us what those paramaters are.  You seem to be an expert on the FAI so you should easily find them.

I'm also curious why there's never a wind/speed direction included with any aircraft speed and/or climb charts.    Puzzeling.  Very puzzeling.

Seems so, coz if you looked a couple of original tests I have posted, you'd see the correction
factors applied..

I 'll post one here - for example..

And what exactly do roll rate and aileron deflection have to do with climbing into a headwind and where on those charts does it tell me what the wind speed/direction is?

What you posted has absolutely nothing to do with what I asked.

What does EAS stand for Baldy?

& did you look at the Spit climb chart?

See the difference weight/thrust/speed makes to climb rate?

See the 'ICAN' & 'Standard Atmosphere' correction factor notation?

See the boost/revs used?

Do you imagine service test pilots are going to include a cheap stunt trick in an official report?

That would not be a valid/representative data set.. would it?

Why don't you find &  post the FAI requirements?

m.m. checked the FAI site out, but didn't bother to link it..

Step up, if you like, Baldy..

I have no idea what you are talking about relative to wind and climb rate....

The chances of flying on a "standard day" are almost nil. Thus, there is a correction for temperature and pressure. There's no correction for wind speed as it is utterly immaterial to climb rate. 

[J.A.W.]

See Rule #4

[Widewing]

Let's see if we can get you to understand the simple physics..

If an airplane is traveling at 300 mph into a 20 mph headwind, its ground speed is 280 mph. Its air speed is still 300 mph. This is because the airplane is moving through a fluid. The speed of the fluid has no bearing on its air speed or climb rate.

[J.A.W.]

Your 'logic' is no more valid than mine.. ( & you were wrong about the FAI)..

& groundspeed/airspeed are 2 dimensional - climb is 3rd..

Anyone got the actual.. scientifically validated.. test formulae to put up?

[pembquist]

I reiterate my earlier post.

[J.A.W.]

& repeating it does not increase its validity..

Any ex-submariners here wanna to chime in..

- on oceanic current flow direction effects on sub climb performance?

L.O.L..

[Widewing]

That is, unless you are doing a 'perfect storm' airshow climb stunt - huh, Ww?

Are you sure 'standard atmosphere' does not include windspeed?

Did you check out those service Spitfire Mk 8 climb rates..

Maybe we can talk Brad Pitt into putting a race-mill Merlin in his Spitfire..

For an attempt on the FAI record..L.O.L...

Sure, someone could install a high output Merlin into a Spit and try for the record.... The record is held by Rare Bear, whose R-3350 was generating in excess of 4,000 hp when it set the record. All of that said, a service grade Spit VIII averages about 1,000 fpm less than the service grade F8F-1 that set the record in 1946, where it averaged about 6,400 fpm.

Also, the best Spit VIII climb rate in that chart was obtained running 25 lb boost. 18 lb was the standard Combat Power setting, and that boost is reflected in Aces High.
