Heh (none / 0)

Your graps of facts is tenuous. Not a single one of YOUR comments has been troll rated, and definitely not by me. I NEVER EVER troll rate someone I'm discussing with. MY comments, including this one again, have been repeatedly trollrated by you.

I don't doubt your credentials, I just say that you have not used them to provide the kinds of arguments that you should be able to muster easily, thus the assertion that your claims are 'unsubtantiated'. With your knowledge, backing what you say with hard facts should be easy enough, and yet you keep on doing it.

I have zero mechanical engineering competence, beyond a decent education in maths and physics. I have provided the kinds of backing for my assertions that I could, i.e. pictures that I googled.

I was the only one to call you mindless; several others encouraged you, so it's not like there's a nasty cabal against you. Yet you chose never to respond with arguments, instead reverting to feeling insulted.

I feel sorry for you.

Re: Heh (none / 0)

You are extremely ungracious - Sven started a conversation about freedom of speech, and you turn it into an attack against me. I would have never mentionned it, were it not for your under-handed attacks against me.

I did not explain because frankly, I have no idea what people's levels of understanding are, and a lot of mechanical engineering is intuitive which is not the forte of the people whose background I know - like Migeru.

I once stepped into a test cell and told the mechanics there was something wrong with the running engine. They had been working with it for weeks. They scoffed at me. I had a closer look at the electronic data that had been stored and found that one of the scales on the display was wrong (off by a factor of 3). The compressor bearing was vibrating much more heavily than anyone believed, probably because it was cracked and was about to rupture causing the entire compressor to spray compressor blades all over the test cell.

To this day, I have no idea why I thought that. There were quite a few engineers and mechanics who were completely amazed. Maybe it was the sound of the engine? I don't know but I was right. And I have been right on many such occasions. You'll probably say that is bragging.

Re: Heh (none / 0)

I'm happy that you have real achievements under your belt, and I am perfectly fine with people bragging about real things. (I gave you a '4' in the other thread when you bragged about something real)

The problem I have is that you have dismissed increasing volumes of (apparent) evidence with curt messages and no real arguments beyond authority ('I know') or spurious stuff ('what you've shown me fits in a suitcase').

There's nothing under-handed about my attacks. They've been addressed to you all along. Sven brought up the topic again, so I responded to him.

Again, you're the one troll rating me all over the place. And yet I'm still arguing here. Which means that I still have hope...

Re: Heh (none / 0)

No, I did not dismiss them. I told them dozens of times: there is no wreckage. Where are the seats? Where is the luggage? Where are the bodies?

They just dismissed me, or showed me wreckage of the air circulation system of the building. I kept asking: where is the wreckage? They showed me a picture of a diffuser case. It takes much more than a diffuser case to make an engine.

I told them that this was the first case in recorded history that an aircraft was vaporized, and they told me that I had to take angle into account. When I told them that the angle, when taken into account, had a very small effect, decreasing the 562 mph forward velocity to perhaps 400 mph, they told me about gravity and terminal velocity. The aircraft hit the building horizontally, not vertically, so gravity had very little effect and even if it did, the terminal velocity of a human being is 120 feet/sec whereas the forward velocity of the aircraft is 762 feet/sec. This was all discussed, but NOBODY WOULD HEAR ME.

I think this is the real issue here and one that I have encountered many times in engineering with engineers. They don't listen when women speak, dismiss their credentials and then claim it was the woman's fault.

I believe you and DoDo are guilty of the same thing.

As for troll rating you, I troll rate you and you call my comments stupid and baseless etc and the worst I say is that you are ungracious, which you are.

Re: Heh (none / 0)

And you say that no plane has ever vaporised. That's not what I've read, and does not correspond to pictures I've seen of other crashes.

You have not substantiated that assertion in any way (apart from accusing us of not believing you just because you're a woman, and not because you make unproven assertions)

I am not French, manon, I am British. Now you know.
I leeched on to your comment simply because it was the last one in the subthread at that moment.
I spoke to you by your name out of courtesy. I wish you would show some.

Now are you and others going to get the fuck out of here and over to the Open Thread???

Re: Heh (none / 0)

and I would appreciate the courtesy of not being singled out.

Firstly, I am not responsible for this discussion on this thread. Jerome is. He changed the tone from one of discussion of freedom of speech on this blog to a direct attack on my professional credentials.

Jerome is also the editor of this blog.

If you were to address a single person by name, it would have to be he.

I am only responding to his attacks against me.

I have no idea why you mentionned my name at all, but if you wanted to give me the impression that you were not aiming at me, you did an extremely poor job of it.

Re: Heh (none / 0)

You were not singled out. I explained to you: your comment was at the bottom of the subthread when I wanted to suggest the discussion take place elsewhere, so I used it to address all those who were in the discussion. I said so very clearly in hopes you would not misunderstand. Whatever explanations I give, you still refuse to understand.

So do what you like.

Re: Heh (none / 0)

The thing is, like I said in the last Open Thread, we have no control over the evidence that we have been given. Hence there is no way for us to say, with absolute certainty: "it happened", or "it didn't happen", without making concessions.

When facts/evidence are not 100% consensually accepted, there is no simple conspiracy that's too unreal, and inversely no simple truth that's too unreal. Occam's razor has not been proven yet. In fact Occam's razor applies to Occam's razor, ie. which of the following makes fewer assumptions:

A) Occam's razor is true
B) Occam's razor is either true or false

Just to wink at you Jérôme for the other night, Ségolène's picture on the beach could indeed very well not be one of her. Or could indeed very well be her and the need to question that is then totally silly. I guess it all depends on context, sometimes we are inclined to accept what we are told, sometimes not.

One last desperate appeal before I go away and shoot myself: this is a huge off-topic subthread which is not fair to IdiotSavant. There's an Open Thread.

Gravity (none / 0)

Let's see... Gravity in fact determines the forces that the aircraft engines can generate, and the lift from aurodynamic effects. As long as the structural integrity of the aircraft is not an issu (i.e., at all times before impact) one can assume that there are no sustained accelerations larger than gravity in order of magnitude. Otherwise passenger flights would be so uncomfortable so as to be impractical. Normal lift basically balances gravity, etc.

So, we have the acceleration of gravity (9.8 m/s^2) and the speed of the plane (230 m/s from 762 ft/s). From this I can construct a characteristic length (v^2/g = 5.4 Km) and a characteristic time scale (v/g = 23 s).

Flight 77 was a 757 with a length of 50m, a wingspan of 40m and a tail height of 14m. The Pentagon is 24m tall and each of the outer walls is 280m long. A typical runway will be typically narrower than the pentagon's walls (under 100m) but at least a couple of kilometres long (the relevant dimension to compare with the height of the pentagon).

Terminal velocity is irrelevant: a plane is not spherical, to recall the famous joke about the mathematician and the cow.

This is all before impact, but there was some discussion of the target approach last night. On impact, gravity indeed seems irrelevant again, except that structures such as planes and buildings are, again, designed so that internal stresses at rest balance gravity. So gravity again can give a useful idea of orders of magnitude.

The great Richard Feynman was once giving a lecture about the forces of nature and he says "gravity is incredibly weak", at which point one of the loudspeakers in the lecture hall fell from the wall. Feynman said "weak, but not negligible".

Re: Gravity (none / 0)

Since manon accuses me of sexism for having placed a comment on the last comment in the subthread at that moment, let me have a go at a man instead: don't you think it's unfair to IdiotSavant to crud up his diary with this off-topic discussion? There's an Open Thread, and no it isn't a fucking firing range and no it isn't fucking open for business and shape up all of you!!!

Re: Gravity (none / 0)

sorry, no - gravity does not determine the forces that an aircraft engine can generate

there are two ways to address this:

the lift you can theoretically get from an aircraft wing
the thrust or torque that an aircraft engine can generate

gravity plays a small part in the lift that you can generate, as a downwards force, but the Bernoulli equation for incompressible fluids (of which air is with a Mach number under .6) is the determining equation here - the lift generated is the result of the pressure differential across a surface (and gravity is taken into account in that equation)

gravity plays no part in the equation of the thrust or the torque that an engine can generate - this is limited by the efficiency of the compressor, which is dictated by its mechanical design and the physical properties of the fluid (air is considered to be a fluid) being used
