How are rotational velocities calculated for multiple rotors in rotordynamics?
|
Even when there is only one rotor, the rotational velocity input using CMOMEGA is used only to determine the direction, not the magnitude. When there are two rotors, and the input looks something like this (Ref: Advanced Guide section 8.7): harfrq, freq synchro,, inSpool cmomega, inSpool, omega1 cmomega, outSpool, omega2 then - the rotational velocity of inSpool is freq*2*pi - the ratio between the rotational velocities of outSpool and inSpool is considered constant and equal to omega2/omega1 - the rotational velocity of outSpool is then freq*2*pi*(omega2/omega1) |
