My father flew the G model out past M2.0. He was the first in his class to do so. He said he was a little nervous when at M2.0 he looked out around him and saw the wings mildly shaking/vibrating but still maintained the alt and speed for whatever the mission called for.
Did you have a similar experience at M2.0?
Great. Thanks you.
Same figures for the underwing tanks?
Pretty incredible being cleared for Mach 2.0. Shows you the engineering direction of Kelly. The 104 was a performance bird.
Not sure if you flew them out to that speed but would you say there were “draggy”? Large performance difference to clean?
Were the drop (wing) tanks on the F-4 more draggy than the tip tanks for pylon tanks on the 104?
Alfakilo,
What was the AOA limit on the 104? 22 degrees?
What was the AOA on final?
Interestingly, if the 104 has a lesser gross weight or combat weight, the wing loading would have decreased.
Do you know of a balance or “ratio” of some sort that would define an aircraft for a particular role? I am asking for an answer to a hard to ask question here. For example, if the 104 had a wing loading of around 80 but kept its dimensions and wing shape, etc…, would its “turn performance” – the characteristic that typically defines a dogfighting aircraft – improve?
I understand that wing loading does not solely define the dogfighting capability of an aircraft as low speed AOA and many other factors all play a role.
Do you understand what I am attempting to find an answer to?
If the 104 weighted 7,000 lbs less with all other factoring remaining the same, would the turn radius decrease and the turn rate increase both sustained and instantaneous? This still wouldn’t hide the fact of the 104 being prone to pitch up due to the t-tail.
Was the Crusader designed primarily as an air superiority platform? Did you ever fly DACT against it?
Weight doesn’t affect glide ratios…it only affects the glide speed. A heavy F-104G will hit the ground at the same place as a light one…it just gets there quicker.
That is an excellent piece of information. Thank you!
Wing-size is drag. So every designer is looking for the smallest possible wing related to the mission demands. 😉
Not sure why you quoted me on that. I made no reference on drag of any wing size.
Are you confirming at that F-22’s vertical tail is the same size of the 104’s wing?
Well, H_K wrote “F-104’s tiny trapezoid wing configuration” and I didn’t realise you were only referring to the trapezoid part 😉
Apart from the fact that both have forward swept trailing edges, I’d say the F-22s wing has much more in common with any other fighter wing, like size and leading edge sweep angle.
I wonder if the 104’s wing would be the same size as the F-22’s vertical tail? Looks damn near the same shape.
Alfakilo,
I am unsure of the details of these shoot downs and of your knowledge of the war and perhaps this is unfair to ask but what would have you done differently if you had flown the 104 under the same circumstances knowing what you know now?
You mentioned TOPGUN notes of maintaining an advantage in a rolling scissor and of course the surprising sustained 7G, 420 KIAS below 15,000 ft turn capability, amongst other qualities of the Zipper. These of course were with the G model with a more powerful engine than the A yet the A was lighter.
Were these engagements 1 vs. 1? What would have been your approach? Boom and Zoom or bleed the 21 with a scissor starting at corner?
Would there have been any way to out range the 21? For example, my father flew the RF-4C out of Shaw from 72-74. He commented that a possible strategy to defeat the MIGs, regardless of the current tactics, was to use the F-4’s range/tremendous fuel load to an advantage. He said to “drag the MIGs out to sea” and when they had to RTB being low on fuel, to jettison the tanks and pursue them.
Could this advantage work in the 104 against the 21 – superior range? I would think fuselage AIM-9’s would be the key along with underwing and tip tanks.
Any disadvantages in engagements with the tip tanks (empty)?
No 300%… The actual number of confirmed kills MiG-21 vs F-104A is 4:0 + 1:0 for damages. With the claim of 6:0 out of my memory I was actually pretty close.
Your hectic effort to attack me on all fronts lets me think that with those comments I have hit your bad nerve, right? Aren’t you accidentally a former F-104 jock who cannot stand the fact that his beloved bird wasn’t the greatest thing since sliced bread?
Take it easy, bud. The F-104 wasn’t among the most successful fighters and the few opportunities to meet its opponent fighter aircraft did not end up so well. So what? Whether it was weather, tactics, training, capabilities of the opponents or just plain luck we don’t know. It’s just like it is, you won’t change that by shooting the messengers.
Pretty funny. Alfakilo stated in a recent post that he would choose a better radar, a GIB, and a second engine ala F-4 for a fighter platform.
Have you read any of his posts? Google “Ruminations in the 104” by Walt – also a member here. The capabilities of the Zipper are badly misunderstood and the real potential of the 104 is lost in the usual party line of poor range, lack of turning ability, ad infinitum…
I certain don’t have to defend Alfakilo and Alfakilo certainly doesn’t have to defend the Zipper although I see his position as one who likes to provide facts and educate the rest of us who only have opinions.
I don’t think the F-22s wing is best described as tiny.
In fact, low wing loading was one of the design goals. Can’t really say the same about the F-104 😉
Where did I make reference to the F-22’s wing as tiny? And where did I make reference to wing loading or design goals?
My reply was in reference to the trapezoid shape of the F-22’s wing being similar to the 104’s wing.
If you are going to quote what I have posted or another’s, keep it on topic.
I’m more skeptical of the F-104’s tiny trapezoid wing configuration. For starters, it’s never been repeated elsewhere.
F-22.
Regarding performance numbers and REAL WORLD flying experiences, read Alfakilo’s posts and those of WaltBJ or BJWalt. On second thought, don’t read any of these posts as you appear to have your mind made up on the Zipper.
Do we know the real world thrust numbers for the 135 dry and wet for use in the F-35?
Is wet thrust near the 52,000 lbs mark?
Regarding your above post Sens and the lower thrust of a fighter engine at low speeds;
During Red Flag launches, Flankers did not use burner but Eagles did and the Eagles had a centerline or 2 wing tanks.
Does this difference have to do with more dry thrust of the Flanker or perhaps superior aerodynamics at lower speeds or, the weight of the Flanker in a clean configuration is less than that of the Eagle in the above mention loadout?
I have read that the 104 was limited to 7.3 G. Was there any way around this? Was it possible to pull more G?
This 7G is sustained below 5000 ft at a corner of 510 kts according to the RCAF pilot I mentioned in an earlier post.
Could the 104 pull 9G instantaneous?
What altitude did you top out at?
The TF was 600 lbs of fuel lighter?
750 KIAS was with tip tanks?
What did the slow speed climb consist of?
Take off flaps, 40 degree nose up and 350 in burner starting at 10,000 ft?
Agreed. It was this article that really opened my eyes to the engineering of this little jet. WAY ahead of its time.
I read a book about the Starfighter written by a CAF pilot that really opened up the factual story (the essence) of the Zipper and what it could do and how effect it was low level and the performance of its J79.
FL730, burning 100 lbs a minute, bellying up at 60,000 ft boom n’ zooming… talk about kinematics. Puts the F-22 in its place.
Funny, after I read Walt’s article, the F-22 lost is shine when I learned of its operating parameters i.e. M2.0 @ 60,000 ft. Didn’t seem so spectacular.
I read a post by F-22 pilot “Dozer” saying a 570 Kt pull into the vertical after take off saw M0.99 at 30,000 ft in the pure vertical in full combat configuration.
Do you have any experience performing a similar 600 kt pull in the Zipper? If so, what were the results?
Put together the FL730 story along with your Eagle DACT account, and then top it off with the takeoff demonstration of the Eagle’s 90 degree, 250 kt slow climb and the 104’s 400 kt, 60 degree climb out (was that you again?) with AF Brass looking on, and the non-believer becomes a disciple.
With these kinds of basic performance numbers, it is a wonder the Zipper isn’t flying somewhere in the world even for a non-military application.
Care to comment on the performance increase if a modern engine such as the 26,500 lbs thrust F414-EDE (similar size) were installed?
