urgent S-76C++ help needed

[CX524]

Hi guys, im currently a student at Vaughn College in New York and I'm doing a research project on the Sikorsky S-76C++, my project is due next week and I've been searching desperately for information on the transmission and rotor system of the S-76C++, I've tried emailing Sikorsky but didnt receive any replies, can someone please help me and provide me with some information on those two topics? any help would be greatly appreciated!

What info do you need? What level is the paper that you are writing?

The rotors and transmissions are virtually identical in all S-76 models, BTW.

the professor wants a detailed description of the transmission system, so I need to present to him how the transmission system works, the name of the transmission system, and the manufacturer of the transmission system, and the same thing for the rotor system

Im also having a very difficult time finding all the companies that are involved in the production of the S-76

I basically have to make a 20 minute presentation on the S-76C++ with pictures and detailed description of everything :ugh:

Left it a bit late dont you think??

[NickLappos]

The names of all the manufacturers are easy:
Sikorsky

If you PM me with your email, I will send you a few pics I have found of the transmission system, and my cell number so we can talk. I was the chief test pilot on the S-76 and perhaps can give you a little background, but what are you going to do with the remaining 4 days? ;-)

most of my project is actually together already, the one urgent topic i had nothing on was the transmission, the rotor system i have some information, and the companies involved in the S-76 i also have some information...just not as detailed as i liked them to be

thanks a lot for the help Nick! i really really appreciate it!

Nick, you just gave him the most impressive endnote in his class. "And what were your sources for your project?" "Oh, just the chief test pilot..."

[CX524]

Hey Nick just making sure, did you get the PM? Im totally new to this forum so i dont know if it went through

[Wizzard]

Of course he's left it a bit late. He's a student - it's the law:)

Type "transmission" in here to get tantalising taster (which doesn't work):

CX,
I sent my cell number and two pictures to you at your .edu email address. The cross-section of the transmission shows the principal gear paths, as does the second sketch.

We all expect a detailed debriefing on how things went. Grade, comments, # of phone numbers from impressed fems, etc. :)

[CX524]

Been out of the teaching game for over a decade now but have a youngster at Uni. When I walked out of the clasroom for the last time students left assignments till the night before & the worst that eleventh hour trait produced might be the odd paragraph copied verbatim from an encyclopedia.

These days junior tells me he & his ilk have to beware 'The Sweeper', a piece of software that scans their assignment submissions lookin' for slabs of text lifted from the internet.

Personally I miss the world I grew up in where everything wasn't quite so serious.
