Detailed Description

Base class for trim models for handling blade characteristics and thrust-torque relations.

Usage

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

Mandatory entries (runtime modifiable) trimModel <trimModel>;

<trimModel>Coeffs { Conditional mandatory entries (runtime modifiable)

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

where the entries mean:

Property	Description	Type	Reqd	Dflt
trimModel	Trim model specification	word	yes	-
file	Name of file containing profile characteristics	word	no	-

Options for the trimModel entry:

      fixed       | Fixed blade/angle characteristics
      targetForce | Target thrust/torque by using time-variant blade characs.
