How to calculate VTOL hovering thrust? +some questions about VTOLs

[POLPOX 779]

Y32 setAirplaneThrust 0.449

V44 setAirplaneThrust 0.647

This is enough to hover those VTOLs hover somewhere fixed position, but this is handwritten number.

I want some code/math to calculate this value from getMass or any configurations like envelope[], thrustCoef[], throttleToThrustLogFactor or anything, but I've really no idea how.

Thanks for your idea.

 

//Test code
vehicle player setVehiclePosition [[0,0,0],[],0,"FLY"] ;
vehicle player setAirplaneThrottle 0.647

 

Also: is there any way to detect engine direction/enabled or disabled auto vectoring?

You could write a PID controller (various examples on how to make one can be found using google) using vertical velocity as a process variable and 0 as setpoint (since you want the vtol to hover) and use the output to control the setAirplaneThrust value.
