Flight Model (FM) Testing Hurricane Mk.I v1.10.20332 Beta

Flight Model (FM) Testing Hurricane Mk.I v1.10.20332 Beta

CONFIGURATION:
The following Top Speed per Altitude (TSPA) test was performed starting with a full fuel load and ammo load (no bombs) and the radiators/cowlings are set to full open (worst case).

PROCEDURE:
The top speed is tested at each of the following altitudes:

Code:

   100ft

 1,000ft

 2,000ft

 4,000ft

 6,000ft

 8,000ft

10,000ft

12,000ft

14,000ft

16,000ft

17,750ft (Spit MAX)

20,000ft

22,000ft

24,000ft

26,000ft

28,000ft

30,000ft

The test begins with an air start near sea level. At each altitude the plane flies for a distance of 15,000 meters (9.32 miles) before climbing to the next test altitude. Note at SL and max altitude there may be some 'pilot error' associated with the data (spikes), therefore you may have to ignore the 'spikes' in the data at these two extremes and visually extend the graphs using the data above and/or below the spike. I am working on C# code to do this automatically, but it is not finished.

During the flight all pertinent data is logged using a C# script. The TAS and altitude (Z_VelocityTAS & Z_AltitudeMSL) data is than graphed (see attached). The graph only plots the max TAS value per altitude. If you would like to viewed/inspected all the TAS values you can do so at my web site http://www.flightsimtesting.com/.

NOTE at my site you can compare one in-game plan to in-game plane, or an in-game plane to one of the many real world data sets that are uploaded at my web site. This was done to make it easier to see how well the in-game plane test data matches the real world test data. You can also change the units SI to imperial, and save any graph displayed by simply right-mouse-clicking on the graph and saving it as an image to your PC.

I am also in the process of allowing you to upload your own in-game and/or real world test data at my web site, after which you will be able to graph and compare data via my web site.

SPECIAL THANKS TO:
FST for double checking my C# script file
FG28_Kodiak for all his help with C# scripts
Ataros for all his help with C# scripts

Nice, thanks. Confirmed what I believed that the spits out climbing us at low level. ;)

Any reason you used the 109 E4B and not a regular 109 like the 109 E4?

Hun?

Not sure how you came to that conclusion based on a top speed per altitude test? You should wait for my ROC testing to make such calls.

On that note, if your looking at the ROC data from this TSPA test at my website, DONT!

In that the ROC data collected during this TSPA test consists of a ZOOM climb between altitudes, thus not a valid ROC test!

None

Ahhh I wondered why the graph was having a fit...

Roger.. near the top of the website on the 'IL-2 Cliffs of Dover' you should see a pull down menu called 'Test Type'.. The default is 'Rate of Climb (ROC)', switch it to 'Top Speed per Altitude (TSPA)'. That will switch the graph below from displaying ROC data to TAS data from the CoD C# log files. Also note, you can switch the units the graphs displays.

Thanks keep it up! :-P

Many thanks!!! Nice work...

so hurricane is much too fast at high altitude.

It climbs faster than the spit currently.
