  3. The AIM-54 used a special pylon for for fuselage attachment. It was also more aerodynamic partially covering the front of the Phoenix. The AIM 7's simply mount in to the recesses on the frame and the 2 upper fins are mounted through an opening in the fuselage that has a split cover that closes over it when the missile is not loaded there like on the F-15 fuselage mount. The F-4's mounted the AIM-7 the same way. It could actually carry another 2, they would be mounted on the bottom of the wing glove pylon. Here is a couple of pics of the pylons.
  4. More than likely it is. I know they are also using the BUFF's over Syria now also. They might be rotating them also to allow some much needed maintenance at home station to occur. Deployment maintenance does eventually have a bad effect on the aircraft. I am surprised to hear about the BUFF radio's. I work fighters so my knowledge of heavies is limited. Is it the requirements for maintenance ie. location within the frame or cockpit that make it bad or is it they are just not that reliable?
  5. That is a good question since everything I have looked at shows that they are launched by first dropping the missile and then the motor activates. It would have a hard time fitting properly onto the fuselage mount points intended for the AIM-7's and 120 because it uses hangars t mount it into its pylon on the Tomcat. Plus also what I reading, the AIM-54 when carried in large numbers (4-6) caused major stress on the F-14's frame. The F-15 uses plungers to push the AIM-7 away from the frame when it fires it. The plunger for an AIM-54 would be huge.
  6. Too put the "R" word to rest, keep in mind that the schemes used in it were the exact same as SDFM since it was SDFM introduced to the states with a different title and spliced together with 2 other series. I know what you are saying about the production in DYRL. It was far better than on the original Macross since it was released originally as a movie.
  7. Dry thrust on the F-15 is 64.9 kN (14k lbf) per engine. With AB it is 105.7 kN (23K lbf) each with the PW 220. But whoever did the schematic forgot that the frame weight would increase with the beefing up of both the frame and the gear to support a carrier landing. They only added in the weight of carrying 4 AIM-54's, so this would be a rough estimate of loaded T/O weight. The F-15 is notorious for its FCF or vertical climb. It does go like a bat out of hell straight up due to the vari-ramps it uses on its intakes and the thrust put out by the twin engines.
  8. Thats a good question F-Zero. I know the majority of space in an F-15 wing is fuel cell. Running the harnesses would be a PITA, The early F-15's had problems with fuel leaking into the inboard leading edge nav lights. Sometimes fuel would seep in and the light assembly would blow due to the fuel fumes in the light. I can just imagine the issues with running the weapons harnesses through the wing for wingtip launcher connections. Plus with the way the F-15 was designed I can bet it would mess with its aerodynamics. The planes aerodynamics were verified before any of its flight systems were even placed into the frame, everything besides the engines and landing gear was placed where it could fit internally after scale frame models were test dropped from helicopters. I read about the F-35's last month. They completed/passed the evaluation requirement by the USAF to be declared combat/operationally ready. It is supposed to happen in the next 5-6 months, that was according the article I read. Nice pics hal, I especially like the the Fokker DR.1 and the Albatross
  9. Wow that is taking Victoria's secret up to a new level....rocket powered panties and bras. I would like to know who the "lucky" woman was that tested those for the first time. She had some nerves of steel.
  10. Its not a requirement for Naval aircraft to have complicated hydro systems. it is mainly driven by the design itself and the redundant backups that most combat aircraft tend to have built into them. I do believe Slide is correct in that the F-14's complexity problems were due mainly to the swing wing it used. If you talk to experienced F-15 crew chiefs, especially the old ones who crewed F-4's they will tell you the F-15 was essentially a redesigned F-4 when it came to the internal mechanic's. It does has its advantages over other aircraft hydro systems, mainly in that the pumps are quick disconnect style using check valves mounted internally in the pump mount plate to close off the system when the pump is removed instead of having a directly attached pressure and return line like the F-16 has. But if you were to read the study material on the F-15 we use for our promotion testing you would be surprised at how old a lot of the mechanical system designs are that it uses. Some of what I read on the Tomcats from pilots was mainly complaints about the A model with that damn TF-30. They said when you were landing it, you were literally flying the engine to the deck. It was easy to compressor stall which was bad news on a carrier landing approach and could also cause them to flat spin in flight. The GE was a blessing to the Tomcat. Spanner try this sight, they had some really good photos and paintings.... https://wall.alphacoders.com/by_sub_category.php?id=57237&name=Jet+Fighter+Wallpapers&page=5
  11. Watched both of them here last week. I guess the Middle East isn't region locked from Japan, which is surprising since a lot of stuff from the US is. The music is good but the second videos motif is little strange.
  12. Finding tools in aircraft happens more often than people think. Back in 95 when the 13th FS was transferring in the new F-16 Block 50's some of the guys discovered a 1/4 inch ratchet with an 6 inch extension with a socket on it inside one of the engine access panels when they were performing the acceptance inspection. I have heard of B-52's with whole tool boxes left inside the wing fuel cells being found when the fuels specialist went in to do maintenance on the inside of the tank. Definitely right about it not being a anything new F-ZeroOne. A navalized F-15.....damn that would need some serious beefing up around the landing gear bulkheads reinforced/enlarged tailhook and completely beefed up landing gear. The only draw back would be another aircraft with an overly complex hydraulic system (F-15's have 4 systems to deal with).
  13. I could see her hacking in some "new" OFP's into the flight control and fire control computers on the Drakens.....lets see how well they "ride the wind" with uncontrollable flight controls and weapon systems. Hell even have her hack the AI to eject them as soon as they try to use their weapons.
  14. Right behind Beltane and Graham, 45....dead and buried....or had my body tied to a missile and launched after a drone for viking style funeral......oh yeah
  15. According to what I read they were actually flying escort for Russian TU-95's over Syria. They have apparently been overhauling the aircraft themselves and have even mounted their own radars in them. This is the most recent picture that is dated (2009). I think there are newer ones but they have no date on them.
  16. Generally unless a system actually breaks hard, we spend less than 8 hours working on them between flights. The turn around time on them when they come comeback code 1 (no defects or problems) is usually an hour to an hour and half. If the pilot stays to do a face to face with the next pilot than we can have them ready in 30-40 mins with refueling and forms documentation times included. Unfortunately Spanner mechanics are people also. I have seen and heard of guys doing some very stupid s@#$ working on aircraft. Where that line was gouged was directly below a clamp on the engine that the line had to route through. It looked like they were prying it to move it and keep it in position while the clamp was tightened. Someone just didn't think about it when they did it. It was a quarter inch diameter line and it doesn't take much to damage those size lines due to the thinness of the wall material. The man hour issue is one of the main reasons the Navy retired the Tomcats. The guys I knew that worked on them said the biggest issue with the aircraft was its hydro system. Hydraulic system failures in flight was pretty common and it was nightmare to fix according to them.
  17. LOL that is not fun at all. We had to shovel the ramp areas around the jets at Hill AFB when it snowed and then move the jets forward from their spots so the plows could pick up the rest. It really really sucked when it just dumped snow all day like it seems to on Windermere.
  18. Phasing is the term we use for the isochronal inspections we do on the jet every 300 flying hours. We depanel them and inspect them for frame cracks, broken harness standoffs, wire chaffing, etc. We also pull the engine if required and rig landing gear components and replace any mechanical parts and flight control surfaces that we discover broken or out of limits. On this jet we had to replace a fuel line that had a sharp gouge in it. It looked like someone had pried on it with a screwdriver. The line supplies fuel to the augmentor spray bar line so we had to perform an afterburner run along with the normal post maintenance run. Leaks are not that common in the fuel lines but the hydro systems do leak a bit. As long as they don't leak under pressure or fluid is literally running out of them we tend to leave them. You are right though it was freaking hot out there tonight it was around 100 degrees with the sun down and felt like it was 120.
  19. This is what I got to do tonight at work.....run ground for a leak check on GE 132 on the jet we just finished phasing today.......
