Default Need real world Spit and Hurri data

Hey guys

First things first, I am not Spit or Hurri expert!

But I want to test out some FM testing code I have been working on..

With that said, could you give me the links to the web sites that contain the ROC and Top Speed per Altitude figures/data for the corsponding version of the Spit and Hurris in the game?

For both the 87 and 100+ oct!

Thanks in advance!

As noted, I am not Spit or Hurri expert (wrt versions) so what I am looking for is a specific link to a specific version thta matches or is as close as it can be to the version in the game

Thanks in advance

This test of the Hurricane should be pretty close:

RAE data:

and the Hurricane I data card:

12lb boost:

I have nearly every Hurricane Book every published and the above numbers are about as good as they get.

Spitfire I:

RAE chart with 12lb boost performance:

Test flight data:

the above data for the Spit I/CSP is about as good as it gets as well.

Perfect!

Thanks a mil bud!

Now.. if anyone else reading this has any comments on these tests..

Please make them know now before I do the test!

You know, special case stuff, say for example the plane did not have a full tank of gas, stuff like that so I can account for it prior to testing the ingame version

Hey Seadog

Started reading the reports this morning.. In the Hurri report they talk about the tests being done for two different cases.. Where the 'Service Load' is 677 in one case and 1,111 in another. Initally I thought this was refering to the fuel load, but from the report I see the fuel load was the same in both cases.

So, what is this 'Service Load'?

Does it have something to do with the ammo load?

Also, I assume this test was for the 87 oct and not the 100 oct?


Any info would be welcome! Thanks in advance!

I would say its the extra ammo?

If you look at this http://www.spitfireperformance.com/ab197.html you can see a rough breakdown of weight...I know its not the model your looking at but judging by that i would say the 'service weight' of ammo would make up the 'flying' weight in total

Default 1st test results

Hey guys

Did a quick Hurrir MkI ROC test

NOTE this was a quicky! Don't draw any conclusions from this! In that I am not 100% sure I had all the settings (boost, mixture, etc) set right.. That and I have not converted the data to standard atmospheric conditions yet.

PS note the Z AGL and ZMSL values are internal game values, that is to say they are not the values that drive the gauges (indicated). Also note that I convert the indicated altitude to pressure and than density altitude. Still need to validate and or prove to myself that the Z temperature can be used in these calculations

In short, don't let these results make you happy or sad!

Just presenting what I have thus far to generate some discussions on the topic and get feedback

I see what your saying.. seems right to me! Just thought I would put it out there as one of those unknows (to me) in the hopes some hurrie and/or britt lingo experts can fill in the blanks here

I think the increased load in the 6750lb test was done by using ballast to simulate the effects of more armour, greater weight from self sealing tanks, internal airframe changes to minimize fire risk and/or full fuel/oil tanks; rather than a variation in ammo load. Also planned advances in avionics such as IFF transponders.
