MattP Posted August 7 Share Posted August 7 I know this is a silly question. But before I start gluing the 'Prop-Blur' P/E blades to the actual hubs. All 4 engines rotate clockwise, correct? I could swear I had a pic of a C-130 landing in Panama on a typical 100+ humidity day, with the spirals coming from the props. But I have no Idea what I did with it...

ziggyfoos Posted August 7 Share Posted August 7 (edited) Just look at any C-130 pic and you can see the blades and which way they'd rotate: counter-clockwise as viewed looking head on, or clockwise if you're in the cockpit looking forward.

Scooby Posted August 7 Share Posted August 7 They definitely all spin the same way. I used to adjust the synchrophaser manually in the cockpit until they went to solid state electronics. These adjustments automatically synchronizes all propellers so that they rotate at the same speed. It cut down on vibrations and increased crew comfort and efficiency. I can’t imagine if one engine was spinning in another direction. That would be a nightmare. Quote Link to post Share on other sites
Dutch Posted August 8 Share Posted August 8 Or if the Herk had contra-rotating propellers, like the Shackleton or Tu-95. Shackleton crews called it the "Growler" and were known for their upper pitch deafness. Quote Link to post Share on other sites

MattP Posted August 8 Author Share Posted August 8 Thanks everybody, I also found a pic of an early MC-130E in the black & green camo, showing the 4 engines in the same direction. Quote Link to post Share on other sites

Had a few syncrophasers on the old MC-130 that would wander off and the engineer would unsync them all and then re-sync them up. Was a lot of vibration for that brief period of flight.
