    If you have ever been in the cockpit of a running fighter, it is noisy regardless of all the advances you make when operating in the atmosphere.....the biggest issue I would see with no helmet is not being able to hear anyone on your com frequency or communicate with them or hear any threat warnings the systems may detect.

    Just something to watch...they may be Mirage's but they are as graceful as they look.... https://www.facebook.com/borntoflypage/videos/1701609606722779/

    The newer landing gear can withstand quite a bit of speed. The overspeed limit on the F-16's gear is 200 kts indicated if I remember right. You definitely don't want the gear up and have a hydraulic failure on your first flight like that and the first flight is literally to see if the concept aircraft flies period and to get an initial idea of its stability in level flight. I know Lockheed was planning on eventually making sales to overseas AF's with the F-22 but at the time the tech was considered too sensitive to give even to our closest allies at the time by our government. Ironic seeing how both Australia and Japan showed great interest in buying them. So instead the government said no you can't have these but you can have this F-35 if your willing to invest in it, I think the Aussies got the raw end of the deal on that one.

    Yeah the big issue with the old SUU-16 and 23's was that the vibrations from the gun would loosen the sway braces. Once they did the gun pods would move slightly during firing sending rounds off target in sometimes erratic patterns. The pods in Macross are held in place from internal locks around the pistol grip while it is mounted in the frame alleviating this issue since there are no sway braces.

    David that sounds about right if you consider the muzzle velocity of the M-61 is 3450 Ft/S. From what I have seen of actual M-61 bore-sites on F-4's that is what the distance from the aircraft to the burm was from my estimation. One thing to keep in mind is that once the Valkyrie goes from fighter to either Gerwalk or Battroid the whole bore-site dynamic changes to point/shoot like a rifle/pistol was in an early WWI style aircraft. The Fire control computer systems on the Valks would more than likely just switch from one parameter to another to account for this. A lot of the newer fighters now are equipped with "dogfight" switches that tell the system to switch from visual engagement to medium and long range (normal mode) also.

    The sad thing about it is that congress was scared out of further requisition of F-22's originally by that idiot Gates. Gates was obsessed with drones, one of the main reasons for the falling out between him and then AF Chief of Staff Meyers was over the drone debate. Gates wanted the USAF to acquire from what I read mainly drones to use instead of manned aircraft. He cited the cost per unit of the F-22 as ammunition even though as production numbers get higher the costs per unit would come down. Well nobody won in that debate. Meyers was forced to resign and retire and Gates remained an idiot when it came to dealing with the AF and aircraft technology. Now that the F-22 has proven its capability there aren't enough of them. Now we are scrambling to come up with something as a stop gap until this "6th gen fighter program" produces something. Definitely awesome footage Spanner! As small as the Gripen is, it is a beautiful and graceful design in flight.

    As far as I know most FBW system FLCS cannot be turned off. I know in the F-16 it has 3 modes reset, norm and maintenance. The pilot always places it in norm prior to engine start and the panel is in a position in the cockpit as to not let the pilot accidentally hit the switch and the WoW (Weight on Wheel) switches in the gear disable the maintenance mode once airborne. They have to be actually trying to switch it in order to reach for it. As for limiters and such, the Alpha limits are set parameters in the FLCC. The only way to change them is to reprogram the computer. Currently test wings are the only ones that actually do this or use these FLCC systems for out of envelope testing. Seto is correct the aircraft would become a brick with an engine that you couldn't control, not the makings for a good flight. These are all safety precautions built in so flight suit inserts (no offense to your dad intended Valkyrie, this is how crew chiefs refer to the bad pilots) can't make catastrophic switchology mistakes. FSW aircraft may not be as pretty to look at but if you want high inherent instability, especially for a fighter it is the way to go. Scyla you are correct as to the way the guns are boresighted. They are sighted to have the rounds converge at a certain range in front. Even in aircraft with one internally mounted gun they are sighted to center in front of the aircraft at a certain range. The range itself is set by the effective range of the rounds and is usually several hundred yards. The cant is subtle enough that when you look at it you really don't notice it just looking at it on the ground. The mounting area isn't so much a question as there have been quite a few fighters that have been designed with guns mounted under or along the intake areas. The main issue would be gun gases going down the intake and choking the engine.

    The actual voice over in the video is singing, so I don't think there was anything of information being said. It appeared to be some form of patriotic/nationalist pride video. It was probably shown to their general public. I don't believe they are comically stupid either but they are very inexperienced as far as aviation technology goes. The current indigenous fighter they have built was an F-5 with a modified twin tail. One flaw in their description of the aircraft is the statement that it is capable of maneuverability but at the same it is so stable it does not require an FBW system. Most fighters demonstrate some form of inherent instability in order for them to be maneuverable But who knows how far they will take this design. I guess we will have to wait and see.

    I was just looking closely at the pic Nazareno posted. It looks like they placed Rafale's on the stern portion of the deck. I think that is a model of the Charles De Gaulle. It only has 1 cat on the bow.

    Unfortunately we won't see the USS America as a full size carrier. One of the new LHA class was named USS America to make people shut up. They need to go back to naming them after either famous warships in naval history or naming them after famous battles from our history. I would rather see one named Intrepid, Hornet, or Saratoga instead of named after a politician. My dad served on the Intrepid back in 54' and 55. He told me during normal weather you could feel the ship moving but when the ship would pitch like that he saw guys that had been in for nearly 20yrs getting sea sick. That is the one thing most people forget also when it comes to carrier aviation. The runway moves depending on the weather. It takes balls to try to land an airplane on such a small space when the sea is calm but the ante goes up 110% when the sea decides to be non cooperative.

    My personal experience watching gun boresights with M-61's is that the the spin up time is non existent. As soon as the trigger is pulled the rounds go off. I watched the JASDF boresight the M-61 on an F-4 at Nytabaru AB. As soon as the the sight supervisor signaled to pull the trigger the rounds went off and tracers were streaking into the burm The lag they speak of is only noticed in film footage that is slowed down. As Valkyrie pointed out most pilots only pull the pilots pull the trigger for roughly 1 sec. That is all that is required if they have a good bead on the target. The M-61 can be driven either pnuematically or hydraulically. In the F-16 it is driven by hydraulic system B. The differences in lag are so unnoticeable in the guns that as Valkyrie pointed out it boils down to tactics and experience in the end. Seto you are absolutely correct on the feeling of satisfaction of seeing brass go everywhere when the trigger is pulled and hearing it rain on the ground.

    This is a little off the current thread flow but I spotted this little throw back to current aircraft. I saw it last night when i was watching episode 2.........tridaire fasteners on one of the quick release maintenance panels on the VF-31....I guess you can't replace something that works do well..

    What kills me is that they actually thought no one would recognize it as an R/C aircraft.

    I am glad you liked the post Warmaker. It brought back some memories for me too, seeing my old jet and the first unit I ever deployed to the sandbox with. Now seeing all the youngsters doing the job makes me wish sometimes i was younger also but....the AF has gone downhill so badly now I realize why i am happy being retired from AD.

    What I thought was even better is the video of its supposedly first flight

    Damn I would hate to have to remove a few of those panels along the front intake in real life. It looks like you would have to take off that entire upper fuselage cover to get to the upper screws. Excellent work though I like the screw details you included.
  18. grigolosi
    I kind of suspect that the inspiration for the VF-14 was also the SR-71......I don't know maybe the shape or something.

    Try this one Spanner they had large number of good photo's....... www.desktopnexus.com/tag/jet-fighter/ Nice Red Flag Nellis footage. I worked with them in 07' when they participated in the Red Flag Alaska. I have some of the ammo linkages from when they did some target shooting out on the range with the 27mm's. They are tiny compared to alot of other aircraft they only carry one cannon and they only carry around 130 rounds of ammunition.

    The best way to fix a P&W. Remove from aircraft and replace with a GE......end of problem. The only good engine they have produced in the past 30 yrs is the F-119 and they had to hire ex GE engineers to design that. It looks like a great idea though but all it takes is one warped shaft and you have a million dollar version of a sneaker in a washing machine.They have been around for several yrs but getting them to work as they are intended has been an issue. I have never seen any gearbox mounted to a jet engine that will last the life of the engine. But if P&W wants to put that guarantee on it more power to them.....I hope it doesn't bite them in the rear.

    The only things that would have required a TFOA are the drops where the MER was punched off also, unless that was an actual pylon/munition stores eject test to ensure the stores jettison system was functioning with the pylon design. If you look at modern F-16 loadouts, The station 3 and 7 TER's are not loaded with a bomb on the inboard facing position due to the fact the bomb when it comes with a tank on station 6 has a nasty habit of striking the wing tank. This is especially true with CBU's since they are designed to spin once the fins are deployed on drop. The AF is considering an off the shelf CAS for smaller SOF operations where the operational day to day costs of operating larger aircraft like the F-35 or legacy fighters are not cost effective. I know from what I read, the information collected on the 2 OV-10's used over Syria is still being analyzed and until the AF gets that info they probably won't even attempt to make a decision on any future off the shelf CAS bird. The F-35 is eating a large amount of the budget as Schizo pointed out though so that will influence any plans on it. While I was at Eglin just before I retired from AD, Beechcraft had 3 AT-6's there for weapons testing. That is an impressive little plane when it is loaded up with bombs, rockets and gun pods.

    Now to liven the mood a little.....the reason we drop test every munition and tank that comes off an aircraft.....just click the link it will come up on a public FB page https://www.facebook.com/bloodyfighters22/videos/692547500847558/

    Sildani to answer your question, yes and no. Most modern aircraft avionic systems are LRU's. The bad box is pulled and a replacement is installed once the avionic pointy heads figure out what is wrong. After that the bad part is sent back to the manufacturer for repair. This actually applies to the mechanical systems also. Items like accumulators, brakes, APU's, Hydraulic pumps, shockstruts, etc. can all be rebuilt/repaired either on the base in the back shops or at the depot (in the case of F-16, A-10 and C-130 this is Hill AFB). So in most cases the parts needed are available but in some cases they have to wait for the part to arrive from either the manufacturer or Depot. This happens for all the aircraft in service. This is also why aircraft squadrons usually have a designated cann bird. This cann program rotates through the squadron aircraft and it usually is a 30 day cycle per aircraft but sometimes can go as far as 60 days.

    F-Zero I was reading that back a few months ago that they were in the process of deciding on what aircraft they would choose. I know they were leaning toward the P-8. I kinda figured they would go with it since it is just started operations with the USN starting in 2012 and it is just starting its production run. The Indian Navy and Australian Navy are also purchasing them..

    Oh and we can't forget the metal speed tape........works wonders for covering unsightly openings....and cutting your fingers when you grab it the wrong way...
