Did the Zipper C model get the higher output J-79? I'm sure the A was
lighter and cleaner. Any less stable w/o the ventral fin? The F-8 ventrals were installed to improve supersonic stability, the A's and B's were a little squirrely in the 1.5 range or so. Even the C/K would do a slow dutch roll @ high mach if the yaw stab was not up to spec. R / John R / John "WaltBJ" wrote in message om... Bunch of kids. 22 Jan 1931, Ketchikan, Alaska.

Walt BJ Walt flew the Hot Rod Model A's - an early air-to-air only F-104A with the original small-0bore -3 engine replaced with the -19 engine used on teh F-4E. A 'big' J79 anyway, but not the -17 used in the F-4E, albeit the same thrust. The -19 was the one also used in the F-104S (as you know). I don't know what the differences were between the two engine subtypes, but assume it was accessory locations and the like. To further answer John's question, the F-104A came with various versions of the J79-3, before some of them were retrofitted with the -19. The F-104C had the J79-7 with about 1,000 lb. more thrust in A/B than the -3, essentially the same thrust as the -11 in F-104Gs. They literally had about a Metric Ton more push than the C model (I know, I know, I'm mixing units here, but I'm waxing hyperbolic here), and performance that the documents I have on it, and computations I've done have to be seen to be believed.

The performance section of the -1 (equivalent to the-1-1) for the a/c is quite impressive. I've got the F-104A-D -1 dated 1 June1968, which covers various versions of the a/c with -3B, -7, and -19 engines. The -3B is pretty hot, although there's a bit of transonic acceleration sag (we're talking relative to the later versions here) up to about M1.4, then it really starts to cook. the C w/-7 is better, but the A w/-19 is just awesome. I've been told by someone with access to -1s for both, who's also talked to pilots who've flown them, that even the heavier F-104S can give an F-15 a run for its money in climb and acceleration, and it actually has a greater supersonic point intercept radius (easy to believe with a turbojet instead of turbofan). Naturally, the F-15 wins hands down on avionics and weapon load, and it can fight at speeds below 450 KIAS. The biggest problem I see with the F-104A and to some extent the F-104C is the relatively low G limits when carrying anything more than 1,000 lb. of internal fuel -- It's typically in the 5-5.6G range. However, that's also about the buffet boundary for guns tracking at combat speeds, and I imagine it was widely ignored (as were the Q limits) when necessary. I know of one pilot who had an F-104D model up to 850KCAS (Q limit is 750) at 5,000 ft. MSL in level flight, with a USAF general in the back seat, and he mentioned to the general that they were almost certainly faster than the official low altitude world speed record (held by the Project Sageburner F-4) at the time. I wonder if the G and S had higher g limits - I know the G was strengthened for prolonged flight at high Q for the strike role, and the S was based on it. Guy |

Certainly fast, certainly quick. Couldn't turn worth a damn, but it'd sure
make a vertical fight to water ones eyes. I met Daryl Greenameyer after his low altitude record. His was a kit 104 with a G tail, NF-104 nose, super light with a J-79-10 (don't ask) that was tuned to an inch of its life. Around 815KIAS x's 4 on the course and he never exceeded 300 meters on the flight. Runs were at 60-70' AGL and the film was impressive. R / John |

I don't know what the differences were between the two engine subtypes, but assume it was accessory locations and the like. According to my files, teh biggest difference was a differenct control fir the Afterburner fuel pump, that allowed a continuously variable fuel flow from Min-AB to Max-AB. (That's not a trivial thing - you've got to have soem amount of variable delivery to deal with the change in mass flow qith altitude and airspeed, then throw in some other "logic" (Cams & fueldraulic analog computer, in this case) to nudge all that around to match the throttle commands.)

Naturally, the F-15 wins hands down on avionics and weapon load, and it can fight at speeds below 450 KIAS. That sounds about right. Of course, when you start hanging Sparrow/Apsiede sized missiles on an F-104, you really start piling up drag But Fast. A Back of the Envelope quickie goxes a Drag Index for an AIM-7 on an F-104 to be about 6, (Drag Index is DeltaCD * 10000, of 1 Drag COunt = 0.0001 Cd) It adds up fast.

I wonder if the G and S had higher g limits I don't know offhand. To tell you the truth, I really don't think that it makes much difference in Real Life - you're limited by Buffet at low speeds (And of course, with a T-Tail, the runaway pitchup. Definitely Nature's Way of sayig you've pulled enough G) and at high speeds by Gavailable. Most supersonic types lose pitch effectiveness at high speeds - they just can't pull that many Gs anyway, The F-104 was different - apparently it just didn't care, and at high speeeds, it had lift to burn. Hopefully Walt Bjorneby will show up and correct light on our musings with the torch of experience. - I know the G was strengthened for prolonged flight at high Q for the strike role, and the S was based on it. -- Pete Stickney A strong conviction that something must be done is the parent of many bad measures. -- Daniel Webster |

Pechs ] recently shaped the electrons thusly:
I was in the first class in Beeville that flew the TA-4 instead of the F-9, in 1973. Heys Pechs -- After all the recent discussion about high and fast in the F-104, I'd be interested in your thoughts about the other corner of the envelope. How was the TA-4 (specifically, the TA-4J, right?) to fly around the boat? What adjustments were made to the carqual syllabus vice the F-9? |

Paul- How was the TA-4 (specifically, the TA-4J, right?) to fly around
the boat? What adjustments were made to the carqual syllabus vice the F-9? BRBR I answer-"I only flew the TA-4J, never been a F-9, so I'm not familiar with that A/C around the boat. I just remember seeing the last few adding power everytime they turned when taxiing. The TA-4J was fine around the boat but remember, when I was doing that I had a grand total of 4 traps under my belt from the T-2 onboard the 'Lex'. I was 'busy' whan around the boat in the 'dog', onboard Enterprise no less(BIG boat, compared to the Lex.). But when I flew the 'dog' again in VF-126, the T, E, F and F+ and M models, I found them really forgiving, easy to fly. I would think they would be a neat jet around the ship. P. C.
