Detailed Description

Profile model where polar lift and drag coefficients are linearly interpolated from a polar table by using an input angle of attack.

Usage

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

Mandatory entries (runtime modifiable) profiles { Mandatory entries (runtime modifiable) <profile1> { Mandatory entries (runtime modifiable) type lookup; data ( (AOA1 Cd1 Cl2) (AOA2 Cd2 Cl2) ([0] [1] [2]) ... (AOAN CdN CdN) ); }

Mandatory/Optional (inherited) entries ... } }

where the entries mean:

Property	Description	Type	Reqd	Dflt
[0] AOA	Angle of attack	scalar	yes	-
[1] Cd	Drag coefficient corresponding to the angle attack	scalar	yes	-
[2] Cl	Lift coefficient corresponding to the angle attack	scalar	yes	-

Note

• Angle of attack is internally converted from [deg] to [rad].
