O promenljivoj geometriji krila
Citat:
As Baranek explains, the variable geometry wings brought several advantages to the Tomcat: “At their forward sweep position of 20 degrees (the angle of the wing leading edge), they allowed the F-14 to have a relatively low landing speed, an important consideration for safe operations from an aircraft carrier. As speed increased, they would automatically sweep back based on indicated Mach number (IMN) to a fully-swept position of 68 degrees, reducing drag for high speed flight” (and also to reduce wingspan for aircraft movement and storage – Bio told us that on the flattop’s deck the wings could be swept back to 75 degrees in a position called “oversweep”).
The F-14’s wings could also be manually swept, even if, according to Baranek, the Tomcat’s driver had to consider several factors since “The pilot could manually sweep the wings aft of the position determined by the CADC, but not forward of that position, as that could cause structural damage due to the tremendous lift it would generate. Manually sweeping the wings back could confuse an adversary by giving a false indicator of F-14 airspeed. But it also provided much less lift and less maneuverability, so it was a “tactic” or trick that would be used very carefully.”
This last statement is confirmed by Bio himself who recalled exclusively for The Aviationist, the tale of a Tomcat’s driver who forgot the wing swept aft in the middle of a furball in the F-14 simulator.
“One time in the F-14 simulator (the name of which was 2F112), we completed our planned work and still had time, so we were messing around. A very good pilot was flying, I don’t remember the RIO, and I was out at the control console. The pilot wanted to try to get out of flat spins by manually sweeping the wings aft. I don’t remember if it helped, but after he did it a few times we still had some time left, so he said, “Let me fight a MiG-21.”
The operator set up the simulator and they started a dogfight. After about two minutes, the pilot said, “Wow, this is the best MiG-21 I’ve ever seen, I should have killed him by now!”
Then I looked at a display that showed an external view of the F-14 and told the others at the control console: “Look, he still has the wings swept aft!” They couldn’t contain their laughter and told him, “Check your wingsweep!” The pilot put the wings in Auto and the engagement ended soon after that with a kill by the Tomcat.”
Borba sa Hornetom
Citat:“Around 1987, an F/A-18 pilot went through the Topgun class, and he kept trash-talking F-14s. He called them “interceptors” and bad-mouthed them at every opportunity,” says Bio.
“Most instructors at this time had been F-14 pilots and RIOs, and they decided to teach him a lesson. So they had a former instructor participate in the Graduation 1 vs 1 secretly, and he was flying an F-14A. This Hornet pilot went out for his 1v1 flight, ran the intercept, and as he approached the merge saw an F-14 with wings fully swept.
The Hornet pilot thought, “The F-14 is going 450 knots or more, I’m going to win.” So at the merge he pulled hard into the vertical. What he did not know: the F-14 had burned much of its fuel, so it was light. Plus, it was only doing 300 knots. At the merge, when the Hornet pulled into the vertical, the Tomcat selected wings to Auto, lit afterburner, and did a max performance turn into the vertical. Since the Hornet was much faster, the Tomcat ended up dead six on the Hornet at one mile and called “Fox 2, kill.”
