[RESOLVED] JPT with water too low/engine overperforming

[lukeXIII]

The JPT with water flowing is lower than it should be at the relevant rpm. This means that the JPT with water is usually always lower than the Limit which results in an overperforming engine.

 

 

An example using the JPT in hover chart from NFM-400 compared to ingame:

Conditions: 35 C, 29.92 inMg

 

When using no water, an RPM of 113.5% should result in a JPT of 788 C. Ingame the JPT is approximately 788 C so this is correct. 

When using water, an RPM of 113.5% should result in a JPT of 766 C. Ingame however the JPT is approximately 727 C so this is incorrect.

 

The JPT when wet should be approximately 22 C lower than dry, however ingame the wet JPT is about 50 C lower than it should be. 

This means that the engine can incorrectly reach higher RPMs when wet before hitting the JPT limiter.

JPT in example below dropped by 62 C (around 3x greater than it should be).

Hi @lukeXIII,

 

Thanks for the report. 

We will look into this.

Hi,

 

This should've been fixed in the last OB update. Moving to resolved.

 

Thanks for the report.
