How can I produce a Torque signal to activate an External Force and Torque simulink block?

Hi!
I am currently working on a simulink model that must provide a basic simulation of a rotating helicopter blade. I have been using revolute joints, and what I want
to do is provide a rotating motion to the blade with an External Force and Torque Block. I want to now the rotating speed of the blade, and I thought I could attempt
to model an engine which could provide that torque signal to the External Force and Torque Block and also allow me to know the rotating speed.
I have tried several different things, and I can't manage to get it to work.
¿Could somebody help me out?

Connect a Solid to a Revolute joint. Change the Actuation-Torque property of the Revolute Joint to Provided by Input. You then apply the sum of engine and aero torques to the torque input of the Revolute Joint block using a PS Constant or Constant and Simulink to PS Converter.
