We've launched a You Tube channel called Let's Flight Sim It to showcase some of AISC's capabilities and interests.
Our first video is a flight simulation for the Russian Iskander (NATO: SS-26) short range ballistic missile. Believe it our not, we did picked this project well before the Russian invasion of Ukraine.
This is a 3-degree-of-freedom (3-DOF) simulation based in MATLAB/Simulink (pretty much all of our simulation is done here). The aerodynamic model is engineering level with in-house prediction codes. The propulsion and mass models are based on OSINT performance values. The guidance, navigation and control (GNC) model is a very simple proportional feedback just to get the missile to the target and make it maneuver.
I was frankly a little skeptical of the reported performance of this missile, but not anymore. Even a simple 3-DOF was able to show what this missile could do. It would be interesting to move to a 6-DOF and improve the GNC model and compare it to damage observed in Ukraine. I was able to look at some probable Iskander strikes on a Ukrainian airfield. 11-13 meter craters, wow. All misses, but a few probably hurt pretty bad. Several hundred kilograms of missile coming in at nearly Mach 3 is a lot of kinetic energy. The warhead is a bonus feature. I expected better out of the Iskander, but we can't always assume the missile messed up. Target location error is another factor. As this simulation can show, simply getting the target elevation wrong can lead to a big miss.
