Technical meeting and discussions - Part 6
[Discussions about the inclination angle of the chairs, in order to most efficiently withstand the accelerations sustained during flight, and the cabin's descent in case of separation from the airplane.]
SpaceShip One it's at 90 degrees.
Get on...go to "SpaceShipe One".
Look it up, it's at 90 degrees.
90 degrees in relation to what?
In relation to the axle?
That one sits like this.
It sits vertically.
It has a couple of degrees back maybe.
Ah, you mean in this manner, you put a regular chair?
Yes, yes.
It sits like this?
Yes.
It's not leaned back a little?
No.
At all, at all?
Maybe it might a couple of degrees, I don't know.
3, 4 degrees.
I don't know, it doesn't matter.
That's how this chair is...
It just needs a couple of degrees.
You still need to give it a little something.
Clearly.
But a little bit, not...
A little, yes.
30 like there.
It's not so likable...
40
to come with your belly forward, like this.
Well not at all.
If you don't have some...
some of those, ruggedized, not belts.
Something...
Belts would drive you crazy here in the front...
Mugurel, like those chairs are,
that you close like this, you know?
Yeah I know.
Those that you close like this...
Yeah I know.
and you stop.
Like those at the mountain...
Man, I had a forced landing on a terrain where I stopped very rapidly.
In a landing roll of 5 meters, I stopped.
And I had imprinted...
of course in the cabin everything fell forward, whatever,
but I had marks from the belts imprinted on me.
On my shoulders.
And that doesn't compare to this level.
This type of shock.
Hey, come on, I'll tell you how it needs to...
But...there, with a metallic ***.
and with....4 extensions
They don't want to do extensions.
Meaning integrated in...
That's what I said.
...the structure.
If some structures, some recesses, integrated in the structure, 4 recesses, integrated
But he said that he doesn't, that he doesn't.
It's not that I don't want, you don't need them.
What's the diameter here?
About 50...
30 cm?
54. For 1 meter, 54 cm.
30 cm.
30.
In front.
Yeah, 30 is good there.
It would be good at 30.
So.
At 30cm,
Yes...
at a thickness of 1mm,
Yes...
it can withstand 15 tons.
At 1 mm?
Yes, yes, at 1mm.
At impact?
At impact.
15 tons.
But without impact.
15 tons without impact.
No.
15 ton load.
Wait a minute.
Let me...
Good.
Question.
How?
So, if here there are 30...
Centimeters.
...centimeters, yeah?
Yes.
At what distance from the edge of the plate, if I drill a hole here...
Yes.
Yes?
Yes.
It forks out like this.
Yes.
Yes?
Yes.
Good.
At what distance did you calculate it?
So, if you have a load, distributed uniformly on it,
not at a single point.
And how will you distribute it uniformly?
Well I can't distribute it uniformly.
I gave you an example.
Yes.
That...
if you have a 1mm thickness,
Yes.
and you distribute it uniformly...
All around.
All around.
it withstands 15 tons.
Good.
That I believe.
Now...
That I believe.
... I can calculate, quite simply, how much I have on...
Well yeah...
this centimeter.
you have this surface area.
Yeah.
Yeah.
It's very simple.
And I can even tell you what thickness you need.
Yeah.
Well that's how it needs to be done.
Well of course that's how it needs to be done but I gave you an example so you can see...
Yeah, that's something else.
So,
You have the cable...
No, no, no, not through the cable..
you go through the bushing. [socket]
though the bushing.
Good.
You have a 2cm bushing.
Yes.
Yes?
2 cm.
2....
3 cables, yes?
3...
6 cm.
3 cables, yes.
6 cm...
Times the thickness of the material.
times, yeah, let's say 1 cm.
Yes?
1 cm
Yes?
Yes, it can be 1 cm.
Yes, yes, yes.
Thickness.
12 centimeters.
Thickness, yes.
Yes.
Yes.
9.6 tons.
Meaning 2 times less than we need.
Two times more than we need!
We'll test it.
Because you have no choice.
[When it comes to] the helicopter [drop test], we also have to test...
What?
This instrument.
The distance in relation to the water?
Yes.
And with what instrument they wanted?
With whatever.
No, no, with whatever, the idea is good.
When you're talking about the helicopter [drop test], you also have to test the...
Yes, it's a very good idea.
