[REPORTED] Dora lost Speed/Power Open Beta 2.5.6.50979

Thanks to Saburo_CZ, he mentioned this initially.

 

In current OB 2.5.6.50979 the Dora lost 20km/h on top Speed at SL.

It was capable of reaching ~603km/h before. Now only 580km/h.

Also the powersettings result in strange speeds.

 

 

QNH 760mm/Hg, 15°C, no wind, no turbulence

 

Current OB 2.5.6.50979

3000rpm -> ~560km/h

3250rpm w/o MW50 in tank, MW50 switch off-> ~555km/h (no typo, less speed with higher RPM and ATA)

3250rpm w/o MW50 in tank, MW50 switch on-> ~565km/h, after 5min no damage, flight aborted

3250rpm w/ MW50 -> ~580km/h

 

Closing the radiators at 3250/mw50 kills the engine before a relevant speed increase is observed.

 

 

 

 

Tacview from 10.April 2020:

3000rpm -> ~561km/h

3250rpm w/ MW50 in tank, MW50 switch off-> ~574km/h

3250rpm w/o MW50 in tank, MW50 switch on-> not tested

3250rpm w/ MW50 -> ~603km/h

 

 

Unfortunately I don't have the trk from 10.April

This issue is in both, Beta and Stable.

 

It started with 2.5.6., if data from April are OK.

I did a check with the Dora before 10.April, where I tested speeds before and after bomb release. There I know that I exceeded 600km/h also, but those tacview files are lost. If I find the time, I could revert back to the version from 10.April. But I'm 100% sure that the 600km/h were possible.

I can confirm as I've made a small video where I could not catch up a Mustang that was damaged. I was doing close to 600kph @ SL and it was even faster..

I checked 3000 and 3250 w/o MW50, and am seeing results closer to your older values, this was a quick and dirty test though and I will go over all modes and use tacview etc.

 

3000rpm -> ~560km/h

3250rpm w/ MW50 in tank, MW50 switch off-> ~572km/h

Thanks Norm. Could you provide your test mission? I will upload mine also(altough they're in the tracks).

 

I double-checked my keybindings and the external view for unintended flap, wheel or cooling operation. But there is no conflict. I'll do another test and record a video.

 

 

 

edit: Here is the video. Some parts are 6x accelerated

 

 

 

And the mission I use for testing. QNH 760mm/HG, 15°C, no winds, no turbulence

I think she is OK in performance perspective. Shy flies as fast as she did in past before this bug.

 

The reliability is another question. And i do not think it is about only Dora. The Mustang, at least, is suffering from it too.

Sometimes i think that it is connected with weather setting. I mostly do not have trouble with weather default or standard atmosphere settings.

(when i perform my tests, i usually fly until the fuel tanks are empty, so long flights)

But i have experienced several times engine failure without any reason when i had maximal continuous setting (or lower), several minutes after take off. And it always happened on servers where some play was done with the air temperature and pressure.

Unfortunately without careful testing, it is just (possible) theory...

Agree, I was flying Dora yesterday, she punches through 600KPH mark with ease now.

You may have a point here..
