• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

FSXA Altitude VS Thrust

Hey there everyone, I wanted to have an aircraft that could climb to almost any altitude without losing thrust. What I mean by that is that I would like to have an aircraft with the same thrust that it has at sea level as it has at high altitudes. Is there away to eliminate a thrust "curve"? Please let me know, I want to be able to have an aircraft which can sustain high altitudes without needing to mess up the thrust scalar and have it go crazy at idle. Perhaps there is a fix in the .air file?

I appreciate any input, any ideas are valid:)

Thanks,
Alex
 
Update

This is an update to my first post. I have found out a little more information about the .air files. I have looked at several editing programs (AAM, AirED, and the payware Airwrench (Trial version)). It seems as if the value that I am looking for is in Table 1506, or Turbine Corrected Thrust Factor vs CN1 and Mach No. I exported a table using AAM and this is what it looks like for the 747 (as an example)
Columns: 21, Rows: 3
0 0 0.9
0 0 0
20 0.0254 0.114
25 0.0508 0.222
30 0.0798 0.35
35 0.1125 0.451
40 0.1524 0.545
45 0.1995 0.64
50 0.254 0.754
55 0.36 0.869
60 0.48 0.953
65 0.572 1.04
70 0.653 1.126
75 0.727 1.21
80 0.788 1.295
85 0.875 1.378
90 0.985 1.478
95 1.061 1.578
100 1.153 1.668
105 1.237 1.778
110 1.338 1.845
I APOLOGIZE FOR THE POOR TABLE FORMAT, SEE ATTACHED .TXT FOR A MORE ACCEPTABLE FORMAT.

After much looking around, I have found nothing indicating what the numbers in the table mean. I have found that the left column is CN1 and the top row is Mach No. yet I am uncertain as to what the numbers in the "middle" of the table refer to and what they will alter. If someone could help me out, that would be much appreciated. As I said before, I am working on an .air file which would allow me to take an aircraft to almost any altitude and not lose thrust. I know this is impractical:o, but I am simply experimenting with the simulator and trying to better understand how the planes operate.
Any input is greatly appreciated and I am always open to tips and suggestions. This community is the best out there for MSFS knowledge and I feel grateful that there is such an knowledgeable community. :)

As explained in the AAM help text and in the Microsoft ESP SDK:

The first row is for the Corrected N1 from 0% to 110%

The second row is for the ratio of the rated thrust (defined in the aircraft.cfg) at low flight speed (mach 0.0). For exemple: at 50% CN1 the generated thrust is 0,254 (or about 25%) of the rated maximum thrust.

The third row calculate the thrust for higher flight speed (mach 0.9).

Beware: this is the gross thrust, not the net thrust.

You can find a lot of information about this matter here: http://hsors.pagesperso-orange.fr/index.html

And this is very helpfull too: http://www.mudpond.org/jet_flow_chart.pdf

Ciao, Sergio
