Airmen on the ground keep the Hercules in the air
Senior Airman Daniel Phillis, an aerospace propulsion technician from the 910th Aircraft Maintenance Squadron, uses 400-grit sandpaper on a C-130H’s deicer assembly to ensure it is free of corrosion July 15, 2019. Electrical power from the aircraft’s electrical system is transmitted through the four slip rings to the spinner assembly anti-icing and deicing elements and to the contact brush housing assemblies. Each contact brush housing assembly touches contact rings on a blade to form an electrical circuit for the blade heater element, ensuring the propellers remain unfrozen during flight.
