Question about NREL's 5MW wind turbine inertia of rotation

Hello everyone,
I am writing my own code to perform a coupled analysis of OFWT system. Now, I need the values of the wind turbine’s inertia of rotation to solve the motion equations. Would anyone be kind to offer me some relevant information.

Best regards,

Dear Liang Li,

Which rotionational inertia of the NREL 5-MW turbine do you need and about what what reference axis?

Best regards,

Dear Sir,
Thank you for your reply. I need the roll, pitch and yaw rotionational inertia about this turbine’s gravity center.
Best regards,

Dear Liang Li,

The mass, center of mass, and inertias of the rigid rotor-nacelle assembly (RNA) for the NREL 5-MW turbine are documented in the following forum topic: Using Aggregate Mass in ADAMS to Check NREL CS_Monopile.bmi. Of course, the inertias can be translated to whatever reference axis you want.

If you’re seeking the mass/inertias of the whole system (rotor + nacelle + tower + platform), these will of course depend on which support structure you are using.

Best regards,
