Jetsam Posted August 10, 2009 Share Posted August 10, 2009 Just curious: If standard day (ISA) max TIT = max torque? i.e. C-130E 970 C TIT = 19600 lbs torque? cheers! J. Quote Link to comment Share on other sites More sharing options...
pjvr99 Posted August 10, 2009 Share Posted August 10, 2009 Hhmmmm ..... my calculator doesn't want to do -7 engine, but 19600"lb at ISA on an A15 would only be 97.3% Quote Link to comment Share on other sites More sharing options...

pjvr99 Posted August 11, 2009 Share Posted August 11, 2009 Performance is done at 1050°C or 19600"lb, whichever comes first. In winter zero-time engines often get 19600 at around 1025/1030°C, giving performance between 108 - 110% Quote Link to comment Share on other sites More sharing options...
Dan Wilson Posted August 13, 2009 Share Posted August 13, 2009 He looking for -7 numbers. According to my olde timey whiz wheel it looks like 16650 inlbs or so, SL, 15c, and 971 static TIT. Dan Quote Link to comment Share on other sites More sharing options...
AMPTestFE Posted August 13, 2009 Share Posted August 13, 2009 I got ahold of one of these....I assume it's for 100% engines? Also, the revolving line-it-up thingy is busted....anyone want to sell theirs? Quote Link to comment Share on other sites More sharing options...
Jetsam Posted August 14, 2009 Author Share Posted August 14, 2009 Thanks, Dan! Quote Link to comment Share on other sites More sharing options...
Dan Wilson Posted August 14, 2009 Share Posted August 14, 2009 Yep, based on 100% engines. The whole 95/98% efficiency thing didn't come about until long after the wiz wheels bit the dust. Used to have one for -15's as well but it disappeared somewhere over the years - dang it! Dan Quote Link to comment Share on other sites More sharing options...
airnav Posted August 14, 2009 Share Posted August 14, 2009 I'm a closet geek when it comes to these things........I actually collect them. After I've had them awhile, I will see if museums, or individuals are intersted in them for display/souvenir purposes. I'll check the cabinet and see if I have any extras. If so, I'll contact you and get your address. No charge! Kurt P.S. e-Bay is a good source. I once saw, and purchased an E-6B from the early 40's. All brass w/ engraved numerals and letters.

I hadn't seen it mentioned yet but if my mind serves me correctly you had to be down to -5 degrees (F) to get 19600 from a -7 motor. I'm not even sure if I can find my old -7 1-1. ISA standard day wouldn't even get you close. Dan I still got my -7 whiz wheel too...somewhere! Never got hold of a -15 one. Quote Link to comment Share on other sites More sharing options...
stoney Posted August 14, 2009 Share Posted August 14, 2009 I still have one from the -9, -7 & -15. Stoney Quote Link to comment Share on other sites More sharing options...
Dan Wilson Posted August 14, 2009 Share Posted August 14, 2009 Dan I still got my -7 whiz wheel too...somewhere! Never got hold of a -15 one. I ended up with -15 and -7 whiz wheels when I first started flying with the EC-E's. Damn squadron had quite a selection of equipment on the airframes, -7 engines and -15 engines. Old wings and new wings and IFR and non IFR made the old pubs bag pretty heavy!! Dan Quote Link to comment Share on other sites More sharing options...
peteinuk Posted July 10, 2012 Share Posted July 10, 2012 Dudes..... I am an ex RAF flight Engineer. I flew C130K's** for the RAF '73 to '82.. I then went on to fly Jet transports, and finally left the military and flew Jumbo's for 10 years in civvy street. I now, in semi-retirement, teach train and examine in a C130 flight simulator in UK. I have been looking around for the last couple of years for one of these C130H (-15) Take-off & Landing computers and stumbled across this discussion the other day... Would anyone happen to know where i can locate a Telex -15 wheel?? I've searched high and low and come up with diddly-squat, unfortunately. Many thanks if you can help.....Pete Harker/uk (peteinuk) imij100@cotswoldwireless.co.uk ** C130K: T56A-15 engines driving Hamilton Standard 54H60-91 props (K = sort-of 'H' model) Quote Link to comment Share on other sites More sharing options...
Bob L Posted July 10, 2012 Share Posted July 10, 2012 I have one dated 1976 which I haven't used since the early 80s. However, I am not interested in getting rid of it. But, here some additional info that might help you locate one. TYPE CPU -127P Mfg.

Dave in WV Posted July 21, 2012 Share Posted July 21, 2012 Dan, I still have my H whiz wheel. We never used them as they were off by too much for pre-rosemont H2s. I used them on the E models. Quote Link to comment Share on other sites More sharing options...

After running my -1-1 charts for 100% and 95% I get these numbers 100%, 15C, SL= 16,600"lbs @ 971C....to reach max torque temp would be -8C (+18F) 95%, 15C, SL= 15,800"lbs @ 971C....to reach max torque temp would be -17C (+1F) All normal bleed numbers.
