What is the body velocity of the "rotor" in aerospace blockset?

Hi everyone, I would like to ask: does the body velocity of the rotor equivalent to the oncoming flow to the rotor (in forward flight of a propeller plane)?

Thanks!

Can you clarify what you mean by "body velocity of the rotor"? Are you referring to linear velocity or angular velocity, or something else?

Hi @Shan Min Hii,

The 'Body velocity of rotor(Vb)' of a 'Rotor' block is the velocity of the rotorcraft expressed in the body fixed coordinate frame as [u,v,w].

'u' is the forward speed of the rotor in forward flight mode. The forward body velocity is approximately equal to the oncoming flow when effects of wind, sideslip and neglected.

I hope this resolves your query!
