And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
It's pretty straightforward. 6 blades, strap around the 3 & 9 o'clock blade roots, single point clevis at the top & lift it up. The prop's balanced forward & aft and inboard to outboard. Hard part of the job is safety-wiring the prop bolts. Not sure how long it would take on the Herk, but I've done prop swaps on Beechcraft 1900C & D's and B200 King Air's in an hour or so, start to finish.
Dowty R391 mated with Rolls Royce A-2100. I think Dowty recovered from a major factory fire a few years ago where that prop is produced. it's different from the C-130H which uses Hamilton Standard Hydramatic and an Allison/Rolls Royce T-56. The T-56 is a straight turboshaft and the A-2100 is air coupled.
Thanks for the update. When I left the Navy, they were still referred to as T-56s. I had a Flight Engineer that wore a Allison/Detroit Diesel ballcap just to piss the Tech Rep of.
I see they had to get out the "medium" torque wrench.
ReplyDeleteFrom a riggers point of view, would be interesting to see them stand the prop up.

ReplyDeleteYep, straight from Dowty in Gloucester. I visited their plant near Cheltenham back when we were part of Smiths Group, before GE bought us.
