Detailed Description

Trim model where the operating characteristics of rotor (e.g. blade pitch angle) are fixed, hence the possibility of varying thrust and torque.

Usage
Minimal example by using constant/fvOptions: rotorDiskSource1 { Mandatory/Optional (inherited) entries ...

Mandatory entries (runtime modifiable) trimModel fixedTrim;

fixedTrimCoeffs { Conditional mandatory entries (runtime modifiable)

when trimModel=fixedTrim theta0 5.0; theta1c 1.0; theta1s 4.0; } }
