A few Questions

Don't all radiators create some thrust as air passes through them?

12. why did kamikaze pilots wear helmets?

[Bark0]

thank you all for the answers so far.

As for the 262, I mean Swept back like F-14 Tomcat's Swept back wings. Was their one that was simalar to the F-14's Swept back design.

You mean the variable geometry wings (I believe that's the proper technical term, someone may correct me on this though...)? Where the wings have two positions, for low and high speed flight (or however they vary, I'm sure someone will correct me on that ).
I think the first aircraft to incorporate that was the F-111.

Swept wings refer to the wings being angled backward, fixed in place at the fuselage. It helps with compressibility when approaching the speed of sound.

No the first to do so was the P40 but the most efficient was the P51.

"Don't all radiators create some thrust as air passes through them?"

Yes they do by the expansion of the heated air. The point is how effective the heat exchange is and how big is the inlet drag. In P-51 the inlet was built outside the fuselage boundary layer in non-turbulent airflow and the inlet could be kept relatively small, thus the exit of the heated air could negate much of the resulting drag.

10)Why did earlier models of US Aircraft not have a "Bubble" Canopy when people knew you could see better out of them?

Manufacturing was probably one factor but bubble canopy is not a problem free feature aerodynamically. Because of the uneven airflow behind it it may cause an uneven airflow around the rudder leading to stability problems, usually at high speed. Later on it was noticed that despite this disadvantage the ability to see well to 6o'c was far more important.

"12. why did kamikaze pilots wear helmets?"

Helmets? That puny brain bucket made out of leather used mainly to hold headphone speakers and oxygen-mask? Dunno, a habit maybe?

I dont mean wings that go back and fourth to regular Position(s) I mean Permanantly fixed. it kind of looks like a F-14's wings swept back only on a 262. I saw a picture of it somewhere and had an Idea if it was photoshopped.

Do you mean Me262 HG?

yea that's it, only it was a Picture with it camouflaged and in Real Life

That is probably one of the greatest mysteries that will never be answered.

8: Japan suffered from a shortage of materials and the metal construction of their planes contained a large amount of magnesium which lends itself easily to initiating fires when struck by bullets.

9: The dual-purpose (oil and glycol) cooler of the P-51 is designed to add thrust and so it had to be placed somewhere at the center of the aircraft.

Shortage of materials (Japan wasn't suffering from shortages of material during the time the Zero was being designed (2nd Sino-Japanese War)) did not increase the likelihood of the Zero catching fire, nor the T-7178 aluminum alloy specially developed by the Japanese for the Zero.  What did increase the chances of the Zero catching fire was the lack of self sealing fuel tanks.

US pilots would often aim for the back of the cockpit because that was the location where the oxygen bottles was stored on the Zero.  The oxygen bottles would explode, usually killing the pilot and the shrapnel and/or would easily puncture the fuel tanks causing a fire.
