DD(Dad’s Diary) 51

This is just a ¬†continuation of “The Tale Of 2 Helicopters” , ¬†Rotor-Blade Fold Systems were a way to make them easier to move around on ships , and The H-3’s Were first used on Aircraft-Carriers , so the system was Automatic And Quick , as they had to get set and stowed rather fast , so other Aircraft could be Launched And Recovered Quickly! When the Rotor Blades needed to be folded , a switch was selected in the Cockpit , to start the sequence , And The Electrical Systems and Hydraulic Systems work together , First , The Blades are Aligned to the proper position ¬†Automatically , then the Blades Are Folded , Allowing the Helicopter to have a more narrow Profile , and be stored close together. To Fold The Blades , just 1 of the 2 Jet Engines , had to be started , and since the System Didn’t need a Pilot , just a qualified Technician , as the Rotor Blades Weren’t engaged . Sure beat Doing it by hand on the H-2!
