109 e4 performance

[Crumpp]

I speak German but I honestly can't see this test confirming the Vmax values stated in the manufacturer's brochure.

What else are you looking for?? I mean seriously, your whole premise is that Mtt is lying and will get paid for thousands of aircraft despite that presumption.

Does that really make any sense?

Crumpp, I never stated Mtt was lying I am simply trying to find exact values that could be considered reasonable (not too optimistic, not too pesimistic) and as such would be usable to model the Emils in the sim. I am not arguing with you, I am just asking more questions. I understand if you're not interested or too busy and won't reply.

What you wrote and calculated is in acceptable agreement with the real life tests (467km/h for A-1, 2400RPM, 1.31ata 990PS)

Oh and yes, it does make sense, thank you dude.

There's no such thing as an exact value in engineering. EVERYTHING has a tolerance.

• That hole you drilled? Only accurate to within ±1mm.
• The elastic modulus of steel? It's a statistical range that depends on the microcrystalline arrangement of the atoms.
• The shear stress of your wing spars? Depends on the cross-section which is not accurate because of tolerances in the manufacturing process.
• Horsepower you get from fuel? Depends on chemical composition, which is again subject to tolerances and impurities introduced when it is refined and processed.

[QUOTE=Robo.;355377]Quite OT dude I happen to agree with Crumpp in almost all of the things he wrote, I dared to comment his attitude and pointed out that everybody is making mistakes. Nothing to do with you, Sir.

HE-He, such a polite poke in my eye Yes we ALL make mistakes, eh?

Please, as they say in the Army, "Don't call me 'Sir,' I work for a living.
But why all this concern about top speed? Surely you don't just turn your favourite LUFTWAFFE plane and run from a fight!!! I suggest some maneouvring might help (I always have trouble spelling 'maneouvre' - if it is wrong I,m sure you will be kind enough to correct me.

[CWMV]

Turn fighting is for suckers.
Either initiate the attack with a firm advantage or disengage. Never fight fair.
Hence the need for speed!

Twisting and turning with the RAF fighters is a good way to get shot down. Speed is life.

(I always have trouble spelling 'maneouvre' - if it is wrong I,m sure you will be kind enough to correct me.

Maneuver (US) and Manoeuvre (Commonwealth) are the two spellings, I think.

Thanks to all for your good advice, especially the spelling!
Fighting was never my strong suit. Head down, get in close and use the elbows, knees and fingers has always been my style. Of course, thinking back, I lost heaps more than I ever won. Thank God the Testosterone ebbs..

Bailing out (old skydiver) been out maneuvered..manooovered

Explain how the presumption Mtt is lying on their building specification and contractual speeds makes sense?

If you want to become a better combat pilot, I'd recommend taking a look at the following:

In Pursuit

Fighter Combat: Tactics and Maneuvering

And I'd also recommend posting threads in the gameplay forum if you want help or have specific questions.

I really can't understand why there is still disagreement about the max. speed of the Bf109E.

When the manufacturer calculates a speed for a model and verifies this with flight-tests, and sells the plane according to this values

to a known nitpicking customer, the values must be correct or the manufacturer is out of business..

The interest of the manufacturer is to get no rejects, so the production is streamlined to minimize the tolerances.

There is still no real pressure on the manufacturer at this time (1940) to meet the demands, so peacetime quality can be assumed to be met.

When we have now a projected max. speed of 500 km/h i would think that the majority of delivered Airframes met or surpassed this speed.

As even slight faults of the airframe or the pilot would mark the plane as unacceptable, the manufacturer will try to err to the safe side.
