Thread: Old question....new problem...drive-line angles? Sorry.

Tweet

After rereading your posts, it looks like you may have been taking angles relative to the ground??????the only angles relative to the pinion c/l and crank/tailshaft c/l mean anything
Since the C4 rear is stationary and doesn't move around like a normal rear you probably won't have much of an issue---if the rear end moves up and down, then you have to maintain some angular limits--
The newer drivelines I wrote about are kinda like the rag joints on a steering shaft but different--

Rule of thumb (this one actually works) one in sixty-----one inch offset in a 60 inch drive shaft equals ONE DEGREE----and if you are flying one degree off course for 10 hours at 600 MPH you will miss your (pick one) destination,target,checkpoint,refueler,etc by 100 miles, corse if the bomb is big enough-----

Jerry, I think this story has a moral::: If you can't fly straight, carry a big bomb????

PS--Used to love to watch them drop them great big "daisy cutters"!!!! Instant LZ free of jungle critters....


Didn't mean to derail the thread, sometimes it's amazing how my mind works, or doesn't!!!!!!!!!!

I've never been in the military....but one of my favorite satallite channels is the military channel. Amazing what they can do weapons. One of my all time favorite documentaries was on again last night....I think the discovery channel....covering the pursuit of the speed of sound in the Bell X1. Amazing stuff. Wish I had learned to fly. Maybe someday.

Good. I should be ok then. I'm just sweating everything....I'll try to calm down. My driveshaft is 38" so looks like 1.5 degrees.

Thanks,
