JF-17 AI unit almost twice as much thrust BUG

[GumidekCZ]

DCS 2.7.6.12852

Reporting Bug, where Chinese AI JF-17 have more engine thrust than it should have, almost twice as much.

JF-17 use single Klimov RD-93 Russian engine used in pair for MiG-29, so we can say that JF-17 should have almost exact half thrust of MiG-29.

 

General public stats for RD-93:

49.4 kN (11,100 lbf) dry thrust

84.4 kN (19,000 lbf) with afterburner

 

Pair of engines at MiG-29 give us:

100.0 kN dry thrust

162.0 kN with afterburner

 

Now watch and compare stats for AI unit of JF-17 and MiG-29:

 

JF-17.lua:

thrust_sum_max  = 9335,      -- JF-17 51.2 kN

thrust_sum_ab     = 15569,    -- JF-17 84.6 kN

The note created by dev team of this AI unit knew about thrust, but still put wrong numbers here. Why?

 

MiG-29A.lua:

thrust_sum_max = 10160,

thrust_sum_ab = 16680,

 

We can clearly see that JF-17 have almost twice thrust than it should have, almost same thrust as MiG-29 with two engines.

The real thrust values that are used for SFM calculation are in the table_data under 'engine' section.

 

You can safely ignore thrust_sum_max and thrust_sum_ab.

Thanks, didnt know that.

Now when compared tables ... its ok.

Disregard this topic than. Just if you tell me, why these faulty values I reported are in the Lua and if used, than where are used?
