You can enter command-line options via the launcher, or edit the property tree using the in-sim menu, however. Command-line options change a property tree. The sim is a command-line program like a lot of Linux software, and the launcher UI and the in-sim UI don't cover absolutely everything - e.g.Scenery models and terrain improvements are automatically downloaded on demand. The next branch has in-development aircraft. Aircraft project updates since last LTS listed in changelogs are updated by the launcher before flying the moment they are available, and are often available for the previous LTS if compatible.Multiple release streams: Long Term Stable (LTS), development previews, and nightly builds.

Some aspects of the sim presentation, features, and project itself may go against gamey software practices/norms. Being open-source, the sim has received development form the science and engineering community. It's more of a Linux-type scientific software. The project is a bit different from "arcade" commercial flight simulations and flight games. It's used professionally for research and development, and is available for home desktop or DiY project users. The rest are available through 3rd party hangars or from development repositories.

It also simulates space flight in Earth's orbit.įlightGear's flight dynamics engine (JSBSim) is used in a 2015 NASA benchmark to judge new simulation code to the standards of the space industry.įlightGear 2020.3 has over 700 aircraft and spacecraft projects that can be filtered by advancement level in art/FDM/systems in the launcher's browser.

Eventually you’ll get to low enough a throttle setting that the propeller is below its governing range and from there throttle controls RPM as well as MP…but that’s a function of prop mechanics and not the physics of manifold pressure.FlightGear Flight Simulator is a free, open-source, multi-platform, cooperative flight simulator development project made by. ".since most MP gauge-equipped airplanes have constant-speed propellers, the RPM will not change as a result. At least someone else faced this eleven years ago, though in FSX -īTW, found this in an article on mp (italics mine): Being insufferably lazy, I will first search for other piston aircraft with similar power, prop size, and performance, and try their prop tables if that doesn't work, well, bite the bullet and experiment. The above edits should bring things more in line, then it looks like I must deal with those prop tables they correlate prop speed, pitch angle, airspeed, etc. It seems the pitch is reaching max long before hp/mp/speed, so has exceeded the governed range and further throttle increase causes the prop rpm to increase along with engine rpm. Once I'm satisfied with all this, I am back to the original problem - loss of prop control at high power settings. The Shinden's top speed is at 28k ft and its ceiling is 39k. The F8f, the airfile I'm using as a base, had it set for a miserly 10k ft, I currently have it at 30k ft. (Using this for reference - it's for auto turbos but fluid dynamics do not change.)Ĭritical altitude is next, I know what it means but no idea where to set it in regard to this aircraft (everything I read seems in reference to a normalized boost, not to a supercharged military engine). Now I must convert that boost figure to the required max mp and I should have the basic specs as required by the cfg file. Specs for the Mitsubishi Ha-43 are: 2536ci, 7:1 compression, 2200hp at 2900 rpm with 10.1psi (.69bar) boost 1800hp at 22k ft. Thus when I set the reduction gear to its specified setting I got an increase in rpm my guess (probably wrong) is that FS9 pays no attention to the engine redline and will continue raising engine rpm to match prop settings. Hovering the cursor over the rpm gauge gets a popup blatantly stating "propeller rpm", but it is actually reading engine rpm. a mislabeled gauge (and some erroneous conclusions on my part).
Well, as a result of everyone's help, and that utility, I'm back on track.
