Hi everyone (my first post over here),
I majored in physics and worked in aerospace/defense engineering.
I keep running my cranium into the missing? Boeing engine problem. Has anyone put together the engine calculations with BOTH linear and ANGULAR momenta accounted, for 707, 757, and 767 engines at various shaft RPM? I know most of you work in knots airspeed, but how does this translate to jet engine shaft RPM? This might put the Skilling/Robertson debate to bed with 4 Boeing 707 engines and rotational energy added- just a thought... Now if this proves the Civil or Structural Engineers botched their calculations (or covered them up), then we might have another "expert" credibility problem in the 9/11 FEMA/NIST OCT...
We would need the moment of inertia value for the various Boeing engines to get a valid calculation (from Rotational Energy = 1/2 * I * omega ^ 2), with 'I' being the jet engine rotor moment of inertia, and omega being the shaft RPM. Then the rotational energy can simply be vectorially added to the engines' linear energy (1/2m * v^2). Is the Boeing moment of inertia even available?
My intuition tells me that the engines would shear from the wing spurs and become massively energetic "penetrator" projectiles with an extremely high melting point that should survive nearly ANY fire in an albeit damaged condition. I'd suspect that there is likely more rotational energy than linear energy in the jet engines. This begs the question- why weren't there 2 holes at the Pentagon caused by 2 jet engines?
I haven't seen where the jet engine rotational energy has been investigated by anyone, including NIST (although I'm fairly new to the "activist" 9/11 Truth Movement and probably have overlooked much). Also, what is the current status of missing engines and plane fuselage sections?
One more question (and I'm not trying to be morbid here, but I've studied a lot of ballistics, both flight and terminal)- how do you punch a hole in an iron or steel engine block with a high-speed aluminum beer can? (my simplified "poor man's" model of the WTC1/2 impacts being hit by a Boeing fuselage, like di Martini's "pencil & screen")
Thanks in advance for your expertise and brave work,
