It supports software-in-the-loop simulation with popular flight controllers such as PX4 & ArduPilot and hardware-in-loop with PX4 for physically and visually realistic simulations. Manufacturers don’t calibrate engines for 10 seconds of max. AirSim is an open-source, cross platform simulator for drones, cars and more vehicles, built on Unreal Engine with an experimental Unity release in the works. If you seek real power, you will struggle with high EGT at AFR over 19:1. If you combust lots of unburnt crap as aExperts/eExperts suggest with AFR below 18:1 – you will get high EGT no matter what position vanes have…they will still flow hot, unburnt exhaust gases because heat = power = heat. It is called delta flow as my friend, turbine designer, tried to explain me. Open vanes means more flow but less pressure and vice versa. Turbine housing is simply spiral like snail house and vanes don’t change what angle they are hitting blades of turbine because they are at entrance of turbine housing !!!ĮGT is more matter of combustion efficiency. Vanes control flow/pressure and thus speed of turbine. ![]() I don’t know exactly design of turbochargers but my guess is, it doesn’t matter. If you are smart car hacker, you keep same AFR as manufacturer and compromise reduced efficiency in order to gain some more torque. If you want to improve economy, you need to increase MBT (Mean Break Torque) – it means internal changes in engine bore x stroke ratio for example. Fuel economy is a myth and clever marketing scheme because HP sells cars and boost sells turbochargers – if you increase fuelling, you cannot have better fuel economy □
