Homework Statement
Rotor blades attatched to a disc rotate.
The rotor blades rotate at a speed of 15574rpm. The blades are 220mm from the centre of the disc.
These blades are attatched to a disc that is 400mm in diameter.
A force of 8kN/rad acts upon the blades and 600N/rad. (see picture)
Calculate the tangential blade loading.
Not too sure if centripetal force is the same as tangential force though?
Homework Equations
(itex)f=mv^2/r(/itex)
The Attempt at a Solution
First calculated the centrifugal acceleration
(itex)=Mω^2r(/itex)
Centrifugal acceleration = 53197m/s
Then find the centrifugal force
(itex)f=mv^2/r(/itex)
I have the velocity and can obtain the mass and radius.
I'm not so sure this is the right way to solve the tangential blade loading??
I need to find angular acceleration?
Thanks for the in advance help guys.
