"Octoflugerons"?! Okay, I'll bite: WTF is an octoflugeron when it's at home? The name my instructors drilled into me for an impressive, although unintended maneuver, such as, say, spinning over the top while trying to core a thermal (Not being too coordated, and stalling the upside wing (Left turn, right wing, for example. It's Natures Way of telling you to pay more attention. Or pulling too much over the top of a loop in a T-6 and snapping out of it. Wake turbulence can be good for premium Octoflugeron performance. In the case of the AIR-2, the timer for detonation was basically a specially tuned RLC (Resistance, Inductance, Capacitor) circuit. The Fire COntrol System of the launching airplane figured out how long the rocket would take to reach the target, and charge the capacitors to the appropriate value. If all the appropriate conditions were met, the warhead would detonate when the voltage dropped to a certain level. The FCS for a Genie equipped airplane had to be able to track the target, compute the proper pull-up point for the preferred snap-up attack - it could also attack co-altitude - and figure the launch point and flight time. With a flight time on the order of 5-10 seconds, a 2G maneuvering target like a bomber wasn't going to get out of the way, once the rocket fired. The interceptor would be breaking away and down, with the cockpit opposite the target. Since the Genie required no guidance, you didn't have to follow it in. (Very much Lanch and Leave) The AIM-26 (Nuclear Falcon, whic was an option for some F-102s in the early/mid-'60s) mist have been a real fun trip. The warhead was very small, with a kill radius of about 250 ft. (About the same as a big AAM like a Sparrow or Phoenix) One of the problems with the Falcon series was that they weren't able to work out a proximity fuze - the missile had to actually hit the target to detonate. (And they don't call them miss-iles for nothing) Making a proximity fuze that will work through the range of aspect angles and closing speeds that a missile has (As opposed to an AAA shell, which is always coming up from below at some huge speed, and, since its dirt cheap, tends to be fired in swarms) is a difficult task - you've got to integrate the closing speeds, miss distance, the speed that the warhead fragments will be travelling, the shape of the fragment cloud - and, for all I know, whether the missile techs had garlic for lunch, in order to have the fuze determine the right point to set things off. With a "fragment cloud" that travels at pretty much the speed of light, as with the radiation from a baby nuke, you don't have that problem. You do, however, have to keep teh nose pointed toward the target enough for the missile to see the radar reflection and guide. So, you've got to fly toward your nuclear blast, once you've pulled the trigger. Not fun at all - teh light from the fireball would still be enough to blind you, if the flash curtains aren't as good as they think they are. -- Pete Stickney A strong conviction that something must be done is the parent of many bad measures. -- Daniel Webster |
