Atmosphere pressure lapse rate
Hi all, I finally had some time to look in to the atmospheric model again, and I noticed that Earth's atmosphere is much too thin. It basically ends around 25km, which is actually less than the maximum altitude of the SR-71! The dry adiabatic lapse rate model from https://en.wikipedia.org/wiki/Lapse...

Re: Atmospheric flight
The purpose of the stall angle parameters is to reproduce something like the plot in this article: https://en.wikipedia.org/wiki/Stall_(fluid_dynamics) Basically, the lift should depend linearly on the angle of attack for small angles, but for AoA larger than 30 degrees or so, the lift starts to dro...

Re: Atmospheric flight
Hi WKFO, I have actually been working on an atmospheric flight model, without realizing that someone else was doing the same. Maybe we can combine our efforts. My flight model currently has 10 parameters per ship. It simulates lift-induced drag and parasitic drag, aerodynamic stall above a certain a...
