Im just stating that the turn rate/circle of the aircraft exceeds most missiles. gf0012-aust stated the opposite which is not true.
Your right G ratings alone are not indicative of turning capability. However i don't think thats what GF said. As has been pointed out the missile does not have to match the fighters turning radius in real terms, it just has to maintain the intercept track, which over a large distance means relatively small turns. Therefore a 50+G rated missile will still most likely make the intercept track even if you can pull 12G's and have a much tighter turning radius. Individual turning radius is not the comparison that matters.
Purely theoretical but if an aircraft was flying in 8G tight complete circle the intercept course would be constantly changing in a rather large volume of airspace in the shape of an egg. As the missile gets closer the size of the egg gets smaller. The size of the egg (intercept course) and distance to the target will stay a constant relationship. The Missile would be flying an S path to the target pulling high G if it was getting constant realtime intercept course updates. The missiles range would be significantly reduced if this was the case.
Depending on the size of the "egg", the initial track adjustments would be minor, and untill the fight got terminal the missile would probably not need to pull many g's. In any case the next gen AAM's are smarter, the D may be able to predict your likely course of action if you were just flying around in circles.
A better idea would be to put the intercept point in a vastly different position to what it was when the missile was launched. If take the same scenario, you get tracked and the bad guy launches at 50+NM. When the missile launches you'll be heading off on a bearing at probably M.08, the missile will calculate the point were it will be in the same piece of sky as you in the future. Depending on the range this is likely to be dozens of km's in front of you. If you turn back on your original track or put the incoming on your wingtip and hit the burner, you're now heading in the exact opposite direction at M1.5. That intercept point is now dozens of KM in the other direction. If its getting updates the missile will have to pull tighter to make the new intercept track i.e. it will all ways have to lead you. If it isn't being updated then you are either going to be out of or at the outer edge of the missiles acquisition basket, then the PK is gonna be low. Obviously the closer the missile gets the more G's it will have to pull. You do this a few times and pretty soon that missile will have spend a heap of energy trying to make the varied and widely spaced intercept points. The critical point is putting the new intercept point in as far away as possible from the last one. Thats bleeding the missile, and thats why the F-22A will be so hard actually hit with a missile.
If you are flying around in a relatively small circle, the various intercept points will be in a small piece of sky, therefore the missile wont have to expend as much energy maintaining the track. SO when it does have to make some high G's in the terminal phase, its probably still got most of its energy in the bag. If thats the case and you're still flying around in circles then you better hope your EWSP suite can do wonders, or you're toast.
This does not take into account a proximity fuse which will detonate even if the missile doesn't hit the target.
The lethal range for a missiles warhead is 10m AFAIK. That means you have to put a missile in a sphere with a diameter of 20m thats moving at supersonic speeds at a range of 100km+. Talk about threading the needle, you might as well have hit it.
This also doesn't take into account that the recent enemy just keeps flying in a straight line until the missiles hit, completely unaware.
Recent enemy haven't exactly been up to scratch now have they?
Yep the missile has no chance of hitting the aircraft unless it matches the turning circle/rate of the fighter in such a case.
It wouldn't have to match the turning radius of the fighter meter for meter. The tyranny of distance is in the missiles favor here, the later the turn the better. But still even if the pilot put 9G's on the aircraft and turned through 90 degree's unless the missile was at a comparable range to the aircraft at the initiation of the turn. Any more and the distance would mean the missile has to turn fewer degree's than the aircraft to make the track. I'm not buying it.
Such an example would reflect a beyond visual ranged engagements with an advanced enemy. Interesting enough the pilot would see the missile coming and would be able to perform such a 90 degree turn and this is exactly what the pilots are told to do.
They are told to do this because of the effect it has on the kinematic performance of this missile at long range. IF you are going to try to time a last ditch turn to try and throw the missile you're dicing with death. Can you imagine trying to time that? Better to put the missile on your wingtip, hit burner and throw out a TRD if you have one. You'd probably reduce the PK more.
Just as exposure to trashfire becomes an issue.
