Q&A Spitfire Mk XIV


Recommended Posts

Interesting thread, probably way to late but in my humble opinion the Mk16 would be the way forward. The last of the Merlin variants and the most beautiful aircraft ever made.

 

We will be doing a MkXVI at a later date as part of the BBMF pack (pending agreements etc etc)

Ditto: it took guts, whether an RAF pilot, or a Jagdflieger to even climb into one of these engines with fuselage and wings attached and take off, knowing that so many people on the other side were doing their best to ensure that you wouldn't return. Good training and combat experience helped settle the nerves, but it couldn't stop that flak hit, or being shot down by an opposing pilot taking advantage of even the briefest lapse in concentration.

 

Or shot down by your own side even, something that seems to have happened quite often in the thick of it.

How about an F.21? My personal favourite (with Contra-rotating props please! :joystick:)

:)

If the model that then it is a small stretch to put four of those engines together on to a modified Lancaster fuselage and call it a Shackleton

Just open the Window and throw him some candy! Should motivate enough... at least that worked for me most of the time! ;)

Don't you think I've got enough on my plate without worrying about contra rotating props lol

 

Not something that's even on my drawing board at the moment

 

If we ever look at it then it's in the 5 years+ column

i'll have to reinstall il2 and download a mk21 now! Mmm high fidelity flight models!

I think your doing good....matter o' fact...you go ahead and take the day off(paid)...the office will be fine without you for a day....go get some sun....

 

Huzzzah Freedom!

 

What the....

Finally someone knows!

 

We got a product to get out the door in 2 weeks...we could always delay Hawk release so Pete can enjoy some sunshine??

 

Shall I tell the community to come knocking on your door as you gave him permission???

 

No, I thought not ;)

hehe

Make it a chicken and we have a deal! :megalol: :thumbup:

 

Is this when we'll all be shouting with excitement as we're downloading the Hawk then? :music_whistling:

 

Couldnt possible comment :music_whistling:

Some various Some additional gun dispersion data, via Olivier Lefebrve / AAW. This might come in handy for modelling the Hispano guns on the Spitfire IX.

 

Unfortunately only nose mount dispersion data available for the gun, as mounted in the P-38 nose, but given that German results for the same guns in the fuselage and wings display roughly 2-2,5x higher dispersion for wing mounted installations, it would be easy to make an educated guess for the dispersion of the Hispano, and if we get an E variant, for the .50 M2s in the flexible Spitfire wing.

 

 

Here are the results of a lenghty research into dispersion data, which is quite hard to come by...

The data is based on 100% diameter dispersion with 1 mil = 1/1000th of rad, the kind of mount is precised next to the weapon. 75% dispersion diameter is supposed to be half the 100% diameter which seems quite true for most weapons, this value is provided when quoted in the source (M2 data for instance).

 

We can clearly see the impact of the wing mounting compared to engine mounting, the later seems to have absorbed recoil and vibration much better... indeed dispersion is at least 2 times greater with wing mounted weapons.

Engine mount are the most efficient but nose mounting or cowling mounting does not provide the same amount of precision the mount being much more prone to vibration it seems.

 

Note that US data on the M2 is confusing since the reference data comes from a P-38 nose mounted M2, but the US manuals use the same dispersion data for wing mounted weapons. Either the P-38 mounts are really up to no good or the manuals make a wrong assumption when it comes to wing dispersion. I tend to believe the later, i think the wing mounted M2 would have had a dispersion of at least 12mils and probably more.

 

If you quote this data on other sites/bbs please precise the source being AAW. TIA

H means Height (or max dispersion diameter) as i previously used vertical and lateral dispersion values.

 

D means distance.

 

Units are metric.

Look up the Mark XIVe armament for the answer.
