Hi all,

 

The title pretty much says it all. If there is anything you wanna know or discuss feel free to comment.

 

Edit: Ooo, pretty colours.

What is the difference between slats and flaps.

[Dapolish]

It is possible for a neutron star to use its largely proportioned gravity to attract masses of gas to its area,  creating a new star? If so, would this star be a giant due to the huge amount of gravity present within it? Would the gravity simply create a slightly larger neutron star and not cause nuclear fission? If nuclear fission was achieved, is it possible that the outward force of the reactions would be enough to counteract its own gravity, as the neutron star has so much mass. In all of this, is it possible that such a star would have a shorter lifespan due to the numerous asteroids that would also be attracted by the large amount of gravity in the area, most of which containing iron? If i am correct, iron cannot fuse together to create energy. When enough iron is built up in the core, the gravity of the star crushes itself, as not enough power is being generated by the nuclear reaction to make it stable. Even then, that is only if the gravity of the neutron star is too great already...

Flaps are found on the trailing edge (back) of the wing. They increase the lift generated by the wing to allow for lower flight speeds at high angles of attack.  Slats do not really improve lift much but they allow the aircraft to reach higher angles of attack before stalling (lower stall speed).

I'm sorry but this is in the realm of astrophysics I think .  My area is more to do with spacecraft mission design etc.

11 m/s according to Wolfram

My first guess would be using canned tuna to leave a trail that leads to the desired toilet.  If the cat isn't a total moron it should figure the rest out from there...

African or European swallow?

Used to, but barely get the time to anymore.

Didn't know they stopped allowing them.

No clue. I would guess European.

Scary? In terms of workload yes. But f'ing cool if you're into that stuff.

Watch some Linus Cat Tips with the cat training toilet seat thing.

This is more my department, however, I am just a hobby astro-physicist so I'm not sure on everything. Ofcourse it is possible for a neutron start to attract masses of gas to its area, however, for a neutron star to come into existance you need something like a supernova and in a supernova everything besides the gas that already is forming the neutron star will be shot so far away that it will basicly take too long to go back to the neutronstar. After this I think you have a misunderstanding of what a neutron star is, it is just a star with neutrons. Protons and electrons (probably fused back into neutrons) do not exist in it, so neither do the elements. Because of this no fusion or fission can take place. You have no iron, or whatever. The lifetime will not shorten because astroid add iron because iron will not exist, they will just decrease the energy density of the star which might slightly decreases the lifespan.

Iron can fuse together but it will cost energy so it won't fuse inside a star, it will in a supernova where the energy is overflowing. When enough iron builds up in the core of a fusion based star it will run out of fuel and either just stop 'burning' (become a white dwarf or something), explode (become a supernova) or indeed collapse upon itself and form a black hole.

Good answer. Any easy way to think about it is that flaps increase the camber of the wing and shift the entire Cl vs AOA curve up (allowing higher lift at the same AOA) whereas slats extend the curve allowing for higher AOA before stalling. Lower stall speed being a side effect since maintaining the same altitude while decreasing speed would require a higher angle of attack.

 

If you haven't guessed already, my degree is in Aeronautical & Mechanical engineering Although my job is more in a marine industry.

That's cool. I'm thinking of consulting/IT when I'm done. I'm so done with the maths...

FSX is pretty accurate AFAIK.  Kerbal gets the basics right, but avoids al the maths (there's a lot of maths).

I'm am thinking of studying aeronautical engineering, any words of advice before I take the leap of faith.

Honestly, make sure your mathematical skills are up to scratch.  It's a lot of maths and the workload will be big.  There will also be a lot of boring theory, but every so often there's some gold nuggets which blow your mind. (Most recent one was a lecture I had on afterburners or how the SR-71 engines worked at different speeds.)  But if you have a passion for it the go for it, just be prepared to have to work hard.

1.sounds plausible

2.it would not neceserraly be larger it would depend on the mass of bass attracted

3.if enough hydrogen is present, and there is enough heat it may restart.

4.if fusion did restart yea it would counteract the gravity reaching equilibrium as in all stars.

5.stars have masses amount of gravity anyway, asteroids are crazy it would not affect it. However yes iron is at the top of the fission fusion graph thing.
