Why Red Flag exercises are not indicative of aircraft performance
garrya replied to rrohde's topic in Military and Aviation
Another advantage of single engine fighter like F-16 is that they roll really fast , can be almost 2 time faster than F-15 and even superior than F-22 at low AoA -
Why Red Flag exercises are not indicative of aircraft performance
garrya replied to rrohde's topic in Military and Aviation
Iam aware that it is a clean chart , however both F-15 , F-14 are massive aircraft so i think it is unlikely that an aim-120 would really affected their performance Another factor need to consider is logically speaking aircraft would have lauched a 2-4 missiles fromBVR before get into the merge ,it quite unlikely that aircraft get in dogfight with total amount of missiles they carried from start .For expample : i dont think F-14 would have dogfight with AIM-54 , AIM-7 is not that much better either NASA did many test as well and they also tested different set up too and regradless how many test they did i think it still partly affected by human factor and the set up like you said earlier Thank you I think the incident should be treated as the exception rather than the rule, there is also incident where F-15 turn 15G or Mig-25 turn 10G and pilot survive , but i think we can all agree that it not something that can always happen , if turning 9G make not much different to F-14 airframe then i think it is unlikely that they would have limited it down to only 6.5G , surely you can argue that they want airframe to last longer but F-16 , F-15 have 9G limit and they still working now even after F-14 retired About F-14 G limit here is something i can find http://foxtrotalpha.jalopnik.com/an-elite-f-14-airman-explains-why-the-tomcat-was-so-imp-1610043625 Which is what iam really confuse and skeptical about , because at 10K feet the max sustain turn rate of the 2 aircraft isnt much better than 6G ( within the structure limit of F-14 ) and F-16 already have quite significant advantage at mach 0.85 , so by logic at sea level till 5000 feet where F-16 can turn 9G ( much higher than F-14 structure limit ) it would totally dominate F-14 at mach 0.75-0.85 range And i think i did read somewhere that F-14 pilot say F-16 is a monster at sea level ( not sure that an F-14A or D though ) Can you posted F-14 turn performance at sea level ? Or 5K feet ? ,i want to see them -

Btw can you upload F-14D flight manual or tell me where you got it ? ( like the link and stuff ) -
Why Red Flag exercises are not indicative of aircraft performance
garrya replied to rrohde's topic in Military and Aviation
a bit of an extreme example is the SR-71 , at low altitude it is slower than most other fighter , cant even go pass mach2 until 50k feet , but at high altitude it is faster than any jet aircraft ever buit -

sorry I don't quite follow what you mean by the situation is the same from sea level to 35000 ft 2 aircraft have complete difference aerodynamic and inlet , iam pretty sure there would be difference , I don't have the chart for F-14 , but at F-14D limited by the 6.5 G limit should turn a lot worse than an F-16 turning at 9G :noexpression: from sea level to around 5000 feet by contrast going high altitude( 37k feet up ) the variable inlet of F-14 should allow it's engine to have much better pressure recovery result in better T/W and speed than F-16 . wasn't there only 1 or 2 dogfight between F-15 and F-14 ? and they also affected by the same criteria you listed above ? as I understand it F-14 is good at slow speed around mach 0.55 , while corner speed of F-16 , F-15 is is around 0.8- 0.85 mach , so I think the climb ability of F-15 , F-16 should be much better ( they literally have extra 366 km/h to trade for altitude ) , so F-14 better stick to horizontal turning and nose pointing but its horizontal turning is worse than X-31 btw according to this chart F-15 sustain G limit at 10k feet is 8.5 G , so shouldn't it be much better than both the F-16C and F-14D ? . actually iam under the impression that even though sometime pilot managed to pull extreme G , the limit are there so that the pilots wouldn't accidently break their airframe ( same reason why there is G limit when you start carry heavy bomb and missiles ) also seem like all Navy aircraft have that limit F-18E , F-35C also have limit of 7.5G , the F-14 probably have lower limit because it's swing wing is more fragile nevertheless , I think it really hard for an aircraft that have G-load of 7.5G (or lower )to sustain 9G as long as the one that doesn't have Glimit ( or have limit at 9 G ) -

I don't think it would stay the same even if 2 aircraft use exactly same engine they still have complete different inlet system and different aerodynamic like the F-15 vs F-16 , at sea level the F-16 dominate but at high altitude the situation is revert anyway at 10000 ft wouldn't F-16, F-15 vs F-14 be similar to F-16 , F-15vs X-31 ? ( the F-16 , F-15 will use their speed , T/W advantage to dictate the engagement ) -

Radar at pre amraam perid probably not good in lock down /shot down role so it likely that F-16 can get in close by take advantage of ground clutter But you are right that an AIM--54 is better than AIM-7 in BVR role I think defeating AIM--54 should be easier than defeating a AIM-120 especially at close range F-14 has better radar but F-16 has low RCS so they probably balance out -
Why Red Flag exercises are not indicative of aircraft performance

I checkedthe manual again , and yes you are correct:thumbup: my bad , should be more careful when reading the manual. , it quite surprising how a small missiles can add so much drag to F-16 Still wouldnt it more logical if they launched some of their missiles at each others before get in to the merge ? BTW do you have the graph for F-14 turn rate at sea level or 5000 feet ? , I wonder how it fare again F-16 at these altitude ? At high altitude then I bet F-14 is better since F-16 is (for all intend and purpose ) a slug at 50000 feet -

Alright , I just open the manual again , 2 aim-9 on station 1 and 9 have total drag index equal 2 so drag index of F-16 with 6 Aim-120 is 4 +16 = 20 And adding the centerline tank then total drag index equal 27 -
Why Red Flag exercises are not indicative of aircraft performance
garrya replied to rrohde's topic in Military and Aviation
This bring an interesting point if you look at the graph At 10k feet both F-14 and F-16 have compatible sustain turn rate (P=0 )of around 14-15 degree per seconds But F-14 achieve that at mach 0.55 while F-16 achieve that condition at mach 0.85 , that mean while F-14 have smaller turn radius , f-16 will have more speed to go vertical -

Drag index of AIM-120 it self is zero I think , as shown in this photo , AIM-9 on station 1 and 9 have drag index equal 4 , but AIM-120 on station 1 and 9 have drag index equal 0 Oh and since 2 aim-120 at wing tip have drag index of 0 already , you left with 4 Aim-120+ lauch-129 +adapter = 4*4 = 16 There a centerline pylon but judge by the size I think it has lower drag index than wing tank pylon Total drag index of 6 aim-120 +centerline pylon = 23 I think -

What if F-16 was armed like this ? Belly tank dropped in dogfight , 6 Aim-120 +pylon have drag index of 16 -
Why Red Flag exercises are not indicative of aircraft performance
garrya replied to rrohde's topic in Military and Aviation
According to flight manual , aim-120 + launcher + adapter on station 2, 8 , 3 ,7 of F-16 , each have drag index of 4 Seem reasonable enough -

Drag index of 50 may be too high for f-16 in a dogfight don't you think ? 2 external fuel tank on F-16 only have drag index of 35 With 2 EFT +1 ALQ-184 F-16CJ have drag index of 53 An F-16 with 6 AIM-120 will have drag index of only 16 rather than 50 -

turn rate = [1091*tan(bank angle)] /[true air speed in knots] G-load is 1/cos( bank angle) We can estimate what the fastest sustainable turn rate of F-14 compare to F-16 -

I don't have F-14 manual so can you post it ? I only have something like this. In general F-14 is better at slow speed while F-16 is good at high speed , but stay slow isn't favorable in dogfight , enemy will go vertical quick and try dash attack Oh and by the ways what is the respective combat radius of F-14 vs F-16 with same mission profile ? I think we should equalize their fuel load before making comparison , 26000 lbs is f-16 with 100% fuel I think ? -

Why Red Flag exercises are not indicative of aircraft performance
garrya replied to rrohde's topic in Military and Aviation
Iam almost certainly sure that F-16 is much better than F-14 in WvR with 4 AAM and 50% , it will likely wax F-14 in dogfight Do you remember the X-31 program ? , NASA decided to test the effectiveness of thrust vector control , so they let the X-31 dogfight with F-18 , F-14 , F-15 , and F-16 X-31 totally wax F-14 and F-18 in close quarters with kill ratio of some where close to 8:1 , however when face off again fighter F-16 and F-15 , these airforce fighter were able to get superior kill ratio again the experimental thrust vector control X-31 https://www.google.co.uk/url?sa=t&source=web&rct=j&url=https://www.nasa.gov/sites/default/files/files/Flying_Beyond_the_Stall.pdf&ved=0ahUKEwi9-q2B3ZPKAhXGXBoKHfdwCyI4ChAWCCYwAQ&usg=AFQjCNFB5xpHIh7QXt9pnrz_xL47ULmYsg&sig2=o11QHvLGwyqhIbBVKpoP6w -

the point of using F-5/T-38 is that they are small and hard to see in WVR engagement , and iam sure F-22 wax T-38 too , we only see the painting without knowing actual kill ratio so it may give a false impression that T-38 wax F-22 in WVR , it isnt nevertheless , F-16 would be fair more dangerous than both F-14 and T-38 in dogfight -

T-38 likely train again F-22 at WVR , with that small radar i dont think T-38 can be much of a threat to other fighter at BVR -

The point is his number and assumption are absolutely ridiculous and factually wrong 1) for example he said this : ''2005/2006 tests between the F-22 and the F-15 assumed: a) a force ratio of 2 F-15s for each F-22 a realistic ratio would be 2,2x advantage in procurement numbers * 2,19x advantage in sortie rate = 5 F-15s for each F-22'' :megalol: so if there is 10 F-22 in the mission then the red force will have 50 F-15 ? how many air force even have 50 F-15 ? or this ''. Taking into account cost and sortie rate, 12 F-22 would be expected to face 102 F-16Cs '' great very realistic , when was the last time we have 102 F-16 not from USA all in the air at the same place ? 2 ) he said this too : '' a radar guided BVR missile Pk of 0,65 (it was 0,34 in Desert Storm against non-maneuvering (cooperative) targets with no countermeasures; incidentally, Pk of 0,65 gives the F-22 two salvos with Pk of 95,7% each, meaning that only one in 22 F-15s might come to the visual range, whereas Pk of 0,34 would give two salvos with Pk of 64,1% each, allowing one in 3 F-15s to the visual range – and that is assuming that they fired salvos instead of simple additive '' while Mig-29 9.12B didnt have an internal jammer it still have chaff and flares and radar Mig-25 PD even have new N-005 Saphir-25 (RP-25M) Pulse-Doppler radar with look-down/shoot down capability and it have chaff and flare too so his statement that Iraq aircraft are cooperative target that dont try to evade the target is ridiculous 3 ) Iam almost certainly sure that whoever the operator , mission planning of Red flag know more about tactic than Picard and then he put load of other bs comment ''Agressors also “simulate” older Soviet aircraft, newest being Su-27 and MiG-29, latter of which does not have shining turning performance thanks to high wing loading'' :megalol::megalol: clearly dont understand aerodynamic -

Factually wrong article :noexpression: with many hole ex he said USAF aircraft can't jam but most USAF aircraft can carry jamming pod : ALQ-131 , ALQ-184 , there are delicate jamming platform as well EA-6B , EA-18G He said no USA aircraft have IRST except F-35 but actually targeting pod like ATFLIR , SNIPER-XR , LITENING all have air to air IR tracking functions And written by Picard ? :megalol: , that guys have the reputation of making up random formula and posting nonsense to pump up his favorite aircraft (Rafale ):megalol: -
but D-30F6 on mig-31 is a turbofan engine, and with very high bypass value too ( similar to F-135)

yes it is, but i don't understand Russian so i don't know what they write in it Btw, how can Mig-25, Mig-31 fly much higher and faster than Su-27, F-15, Mirage IV?
