Gents,

As of late I have been doing some research into the P&W TF30 engine family and I have run into something of a snag.

I am having a hard time finding complete specifications for the engines, primarily the diameter. I have seen figures like 1.24 meters on some sites, 1.30 meters on another, and on this site (see link below), it gives the diameter of the engine as 42.1 inches or 1.69 meters.

Does anyone here have the confirmed full specifications for the TF30 engine(s)?

Excuse me, I mis-typed. That source link there states the TF30 has an external diameter of 42.1 inches, or 1.069 meters not 1.69 meters as I previously stated.

Could you post the results of your research here? (If you don't mind I guess :D ) I have an ancient book on the F-111 and in it they mention several potential variants of the TF-30 all the way up to 30,000lbs thrust. It was the only time I've ever heard those mentioned.
 
Well, a glance at a table in Jack Connor's The Engines of Pratt and Whitney: A Technical History shows 38 versions of the JTF10A/TF30 ranging from 41.6 inches to 50.7 inches in diameter falling into two main camps


Afterburning models


Engines for the FB-111 are 50.7 inches
The TF-30-P-100 for the F-111F is 48.9 inches
Other F-111 models are 48 inches


Non-afterburning models
Various models for the A-7 are 42.5 inches
The XTF30-P-2 for the Missileer was 41.6 inches


Lengths go from 128.1 inches to 241.7 inches.
 
Gents,

Thanks for the help so far! Specifically, I am looking for the specifications for the TF30 P-412/414 used in the F-14A. I originally though the TF30 family would have the same diameter give or take, apparently I was wrong!

Here are some of the results I got.

From AUSAIRPOWER:
Diameter-51.4 inches (1305mm)
Length- 235.5 inches (5982mm)
Weight- 4251lbs (1928kg)
http://www.ausairpower.net/engines.pdf

From ANFT.net:
Diameter- 1245mm (49 inches)
Length- None given
Weight- 1825kg (4023lbs)
http://www.anft.net/f-14/f14-detail-engine.htm

Strangely, I had a hard time just find these two sources.
 
Good evening!

Hope I am not muddying the waters, but have some pretty complete specs for the TF30-P-412A engine. Source: Modern Combar Aircraft Design by Klaus Huenecke, Naval Institute Press, 1987, p. 127. All units are listed in metric and follow below:

Max static thrust, A/B, S.L.--9200 daN
Max static trust w/o A/B, s.l.--5800 daN
SFC in A/B--2.78 kg/daN x h
SFC w/o A/B--0.66 kg/daN x h
Max mass flow rate--110 kg/s
Bypass ratio--0.91

Engine mass--1760 kg
Specific mass with (w/o) A/B--0.191 kg/daN (0.303 kg/daN)
Specific thrust with (w/o) A/B--84 daN/kg/s (53 daN/kg/s)
T:W with (w/o) A/B--5.3 (3.4):1
Max pressure ratio--19.8
Number of compressor stages--3 + 6 + 7
Combustion chamber type--Can-annular with eight ducts
Turbine entry temperature--1433 Kelvins
Number of turbine stages--1 + 3

Length--5.99 meters
Maximum diameter--1.29 meters
Beginning of development--1967
First test run-up--1969
Quantity production--1972
First flight--1970
Application--F-14

Hope this helps!

The TF-30 afterburner mod. P-3, P-7, P-9 , P-100, P-412 as of 1971. i worked at P&W East Hartford in their Engineering Research & Development Dept. 955 until 1971. Over the years I have heard complaints about the TF-30. It's rare not to hear of problems with any one particular engine. The engines have gotten so very complex with time. With every model update comes its own series of problems. There are times when a clean sheet is the way to go. If Boeing had listened to its engineers instead of management with the 737 Max they would have gone to a clean sheet. They will be living with weight & balance issues until the thing is scrapped or they remove the engine and pylon. Quality is job one not money.

Engines for the FB-111 are 50.7 inches
