The "Aerodynamic Propeller" block is a Simscape component. To make the input ports for advance (forward) velocity and propeller rotational velocity visible, you need to set the "Translational connections" and "Rotational Connections" parameters to the "Physical Signals" option. These settings are found in the "Environment and Dynamics" section of the block parameters, which you can access by double-clicking the "Aerodynamic Propeller" block. This configuration also generates two output ports that provide the propeller thrust and resistive drag.
Since the "Aerodynamic Propeller" is a Simscape block, it uses physical signals for both input and output. These differ from standard Simulink signals as they can include units.

To input forward velocity and rotational speed as constants into the "Aerodynamic Propeller" block and to read the output thrust, you need to convert these physical signals into standard Simulink signals. Use the "Simulink-PS Converter" to transform regular Simulink signals into physical signals for inputs, and the "PS-Simulink Converter" to change physical signals into regular Simulink signals for reading and plotting outputs. Once this is done, the block should resemble the setup illustrated in the image below:
