Good Evening,
Thought you might want to know that the last three (3) squadrons of the CH-46 Phrog will be around to 2014 at least.
Recently within the last year the Phrog got a reprieve when the Marine Corps In Country found that the Superfinish Gears now allow the Phrog to fly with more payload under high hot conditions and that the Gears have Significant Durability due to the 1-3 microinch Superfinish that I introduced to MCAS Cherry Point during Phrog overhauls.
Reason that we had to wait so long was that Boeing was told that they were not responsible for the CH-46 due to advanced age. Then the Depot was finally able to utilize this new technology.
Other news is that the MV-22 and CV 22 will also use this Superfinish technology to recover some of the additional durability required by Marines In Country.
Also the US Army Aviation will be using this Superfinish Technology on the CH-47, AH-64 and HH-60 varients

Phrogs Phorever!
Good news, Wally!
I want my Grandchildren to see these birds up close at some future date and this will ensure that I (or my sons) will be able to show 'em what we had back in "the day", and that it was/is so good that it is flying the next two generations of Marine aircrews!:D
Such a deal!

Back many years ago when I was a youg engineer designing gearboxes we always determined what the gear loss was in terms of lost HP due to friction. By making the gears with a higher finnish it will reduce the loss but it adds nothing to the durability. Having gears with a 1or 2 micron finish will definatly reduce friction thus reducing the overall loss in the gear box. Again it has nothing to do with durability.
It will allow bigger payload because the engines don't have to work as hard to overcome the gear loss.
