Kind of the antithesis there…
If I had substituted ‘frictional forces’ for ‘drag’ then he still would be complaining.
CAT I, II, and III are dependent on the load out. The 370 gallon drop tanks underwing put you automatically in CAT II. The pilot can only select I and III, so the pilot has to know CAT II limitations.
The same issues must rear their heads on their F100’s and F119’s using the same materials. With material strength limitations being what they are, perhaps the larger diameter of the F135 is the issue.
You also realize the big extension in range is due to ballistic flight where energy from thrust is traded for altitude and drag only impedes it gaining altitude. The orientation of the missile will be path of least resistance. During terminal dive the missile will use drag to steer itself to target and the nose of the missile will have a slight angle of attack off the boresight determined by the missile logic. If the missile was perfectly perpendicular to the target it would lose all benefit of its tubular shape. Missiles do not fly typically linear paths, they do generally fly a ballistic path with a variable roll rate. The missile logic’s job is path of least resistance to the terminal phase where it converts potential energy of an object in motion into kinetic energy for a change of said motion as necessary.
I think these basics escapes some of the people posting.
Take the total empty weight of aircraft and divide it relative to the types replacing it. The US was steadily drawing down by this metric since Vietnam until mid-Reagan era. It took another hit late in Bush era. I believe the numbers were published in a magazine, but it may be on the web. The Russians drew down since fall of the wall, with huge drops in the early years. It would be interesting to see the metric down with the latest administration included.
Total tonnage of aircraft is more revealing than quantity.
most Anti air missile don’t roll, except Rim-116
Why do they fly spiral paths? I think you should reconsider your statement.
I like when Dr.Snufflebug appears out of nowhere with these perspective inspectives. Keep up the good work. 🙂
Given that he stated that the F-16 travels 6km in the time the missile flies 24km, that would imply a Mach 0.67 cruise, which is far too low even for cruise. Given that he was about to take a missile shot and may have been tracking the MiG for a while before getting in range, he will probably have sped up from cruise anyway.
A3-6 suggests Mach 0.84 as optimum cruise with DI = 100 and optimum cruise altitude remains over 30,000ft until you get to well over 40,000lbs even at DI = 200. Optimum cruise also remains over Mach 0.8. And looking at C1-9 it’s surprising what you need to get it up to a DI of 200. E.g. 2 x GBU-10 has a DI of 30-34. 2 x triple Mk-82 multi-store (C1-12) has a DI of 64.
https://info.publicintelligence.net/HAF-F16-Supplement.pdfThere were also a significant SAM threat, so low altitude wasn’t recommended.
You fly within your corner speed plateau during combat, not at maximum cruise. The F-16 loaded with fuel tanks is flying Cat II limits at best. (Cat I mode with limits on manuevers.) So once again it’s around 400 knots plus or minus a couple dozen for the plateau. Survival depends on best turning performance, not cruise speed.
A rolling cylinder with angle of attack provides significant lift. The body itself provides lift. Even the old Red Eye manpads used rolling airframe for lift. Some modern missiles have nearly no wings for this very reason, yet still pull 40G.
It’s a significant pre-order even with the new numbers.
That’s actually just you making stuff up. Hardly cut and dry. 24km in 30s is only Mach 2.7 average. Flying at typical intercept altitude (30,000-40,000ft) that is slow for a missile. The article itself says it can travel 33km in that time. Add your 6km, that’s ~39km. Is the time it disappeared from radar necessarily the exact moment it was hit?
I should have phrased it “at most Mach 4”, but the missile is decelerating once it’s fuel is exhausted. It decelerated relative to the conditions. Straight line flight results in rapid deceleration.
And you have a lot of nerve to say I made it up when YOU provided the source and my numbers came from it. Your numbers are consistent with my earlier post about thinking the F-16 is closing at about 400 knots.
Ramjets most certainly can work at 100,000 feet without exotic fuels. And who told you fins are worthless at this height?? They have value.
Missile launch at 30km, impact when target is 18km away. So the gap closed 12km between the shot and impact. If each were closing at the same speed they each went 6km before impact and the missile went 24km in the same span of time. The fighters were subsonic. The missile was Mach 4 and traveled four times the distance.
Pretty cut & dry. The fighters were not flying supersonic.
