Propellors Being Shaped By Machines

The video tutorial explains the process of using gas pressure to shape hot metal against dies. It describes how the shell and core of a propeller are combined and braised together using heat and pressure. The tutorial also covers the filling of airspaces with gas to force the metal into shaping dyes. Finally, it discusses the installation of deicing wires and the use of a compound that hardens to provide interior support for the propeller.

What is the significance of the airspaces inside the propeller during the manufacturing process?

Explain how the deicing wires are integrated into the propeller structure.
