U.S.S. MASSACHUSETTS - BRIEF DESCRIPTION - ENGINEERING DEPARTMENT, is a training manual created aboard the ship to introduce new men to the ships engineering systems.

Richard Pekelney has done an excellent job with the website: Historic Naval Ships Association.

that can go wrong in engineering among those things are you can sag a turbine shaft and usually its the LP turbine shaft. Not a good deal at all.

I have the Machinist Mate 3 and 2 on CD. It has virtually everything you'd want to know about this, including pictures and drawings. It's what the Navy uses to train their enlisted propulsion people. Just let me know if you want a copy.

This book has been revised many times over the years.

Certainly diagrams would be a big help, with a legend for the 'pieces' of the puzzle.

Max Turbine speed on BB59 was 5,904 RPM.

Output speed of the Gear Reduction was a useable maximum shaft speed of 199 RPM.

Resulting in a top speed of 27.5 knots or about 31.5 miles per hour.

At one time there was a complete engineering setup of the Sumner at the San Diego Naval Training Station and another one at the Great Lakes Training Center which were the schools that taught engineering to everyone for all classes of ships.

I think both were dismanteled in the late 50's or early 60's.

But this was the bible to the US Navy from mid WWII until they were dismantled whenever that was.

No. It varied with the amount of steam admitted. This...

on the high pressure turbine on board the "Big Mamie" there are 12 stages when the steam is at the final HP stage exit it is about 50 - 80 Lbs it still had nuff to spinn the Lp turbine when it exits that it is about 1 lb pressure then on to the cycle again condenser, DA tank, economizers, and so forth this is just a brief explanation it is of no other use speed of turbine is controlled by the throttle valve i tried to make it as simple as possible to under stand, dont forget...
