The f-15 is a beautiful machine. Top 5 best looking aircraft ever made for sure. The F-14 was the best looking fighter ever made in my opinion the F-15 follows right behind it. The Soviets or Russians copied the F-15 and built a very nice looking aircraft to.. Not a fan of the stealth fighters. They just dont have the looks of the legacy machines..

Here's the top 5 with pics (how it should be) but I'm gonna try to pick one from each generation. I'm sticking to fighter jets to keep it simple.
WWI
SPAD XIII
WWII
This one is tough, the P-51D is gorgeous
but so is the Spitfire
too close to call, it's a draw
The F4 Phantom has always been a favorite. Big, nasty and mean; what's not to like?
The Dassault Rafale is a beauty queen, too bad is just sits on the shelf.

I question for you, I've always wondered.
Without going into specifics that you may not be allowed to answer, What is the shaft speed, in RPMs for a jet engine on a large plane. Like 747 or B-52 or, or.....
I'm not asking about prop speed on a turbine, but the shaft on a jet engine, the part you shreds the unlucky goose that gets sucked in.
By listening, it sounds quite high, by looking, it seems rather slow although I'll bet the tip speed is up there!

Sorry thems the E series of airplanes..

Some more pictures with the TR and accessory doors open.
Well, there are two different speeds that are measured. N1 and N2. On a high bypass motor like a CF6 on a 74, or my 757 PW2000 derived F-117-100, N2 would be the rotational speed of the core. The core's exhaust blowing out the back has the last job of spinning a few stages that send rotational force all the way back to the front to spin the front fan giving N1 speed. No idea on the actual RPM's as we measure them in a percentage value.

In mid-November 94, GE conducted the fan bladeout test with the FAA present. The release blade was detonated at a fan speed of 2,485 rpm, 10 rpm over the target, with the engine generating more than 105,000 lb. (466.8 kN) of sea level static (SLS) corrected thrust. The engine mount system performed as designed and the test demonstrated fan blade containment.
The ruggedness of the composite fan blade was successfully demonstrated, and the observed trailing blade damage matched pre-test analysis, verifying the inherent benefits of the composite blade design.
