Hi guys, I need some ini Entries for a Jetengine for a plane that can accelarete upt to Mach 5 or something simliar, without blowing up.

 

The bird has 3 of them. I started with the FM and entries of a Mirage3C and here is one entry of one engine:

 

[Engine]

Every the bird explode during flight at Mach 1.38, so I thought I will set the temperatures a bit higher so the engine will be damaged somewhere over the standart parameters. Strange thing is now, the bird explodes even earlier...
Who can give me a hin what entries I could use?
 
best regards

78°C is a bit cold for the CIT, indeed.

 

As a reference: The F-104 has a max. allowed inlet-temp. of 120°C.

It's the max inlet temp thats the most important for engine damage. My Mach 4 "Testbed" (BAE Hawk :grin:) used a max inlet temp of 2000'c without blowing up even though the Engine damage temps were still set to only 500-600'c so the higher the better!

Besides inlet temperature that prevent the engine to explode there are 2 other factors that will permit your engine to go to Mach 5. Dry and WetMachTable.
 

DryMachTableNumData=4  This is how many segment or curves we.
DryMachTableDeltaX=0.4  Every 0.4 mach in this case
DryMachTableStartX=0.0  Starts from 0.0 mach.
DryMachTableData=1.000,0.980,1.172,0.000  At 0.0 mach the thrust is 100% of the value stated above in Newton. Then is 98% and so on...
WetMachTableNumData=7  Same things as above but in afterburning regime.
WetMachTableDeltaX=0.4
WetMachTableStartX=0.0
WetMachTableData=1.000,0.991,1.207,1.683,2.473,2.750,3.027

I am absolutly no ini guys, I have now simply copy paste the F-104 engines into my model, changed the exhaust position and put

 

DryMachTableNumData=2

 

WetMachTableNumData=2

 

There are 20 segments at all

 

The plane simply destroyes the engines directly at mission start?
