[00:01] <hallam> have you done any calcs on the cmg control authority?
[00:02] <Laurenceb> yes
[00:02] <Laurenceb> you only need about 4 grams for the gyro mass
[00:02] <SpeedEvil1> that's assuming you've got the wacky unfolding?
[00:03] <Laurenceb> yes
[00:03] <SpeedEvil1> so you've got an enormous diameter?
[00:03] <Laurenceb> the total mass for the gyro system is <20grams
[00:03] SpeedEvil (n=user@tor/regular/SpeedEvil) left irc: Nick collision from services.
[00:03] Nick change: SpeedEvil1 -> SpeedEvil
[00:03] <Laurenceb> yes, 40cm
[00:03] <SpeedEvil> that seems likely to be quite wobbly
[00:03] <Laurenceb> the rocket is spun up to about 3000rpm before launch
[00:03] <SpeedEvil> does that matter?
[00:03] <Laurenceb> why wobbly?
[00:04] <SpeedEvil> 40cm gyro, with a piviot in the middle
[00:04] <SpeedEvil> it's not going to behave like a solid gyro
[00:04] <Laurenceb> once its spun up it'll be pretty rigid
[00:04] <SpeedEvil> are you counting that?
[00:04] <Laurenceb> not really... you should be able to get the COG pretty accurate
[00:05] <Laurenceb> also its spinning at over 100Hz
[00:05] <SpeedEvil> hangon - the second stage is spinning at 3000RPM - and then you're trying to unfold the cmg?
[00:05] <Laurenceb> yes
[00:05] <Laurenceb> thats how it unfolds
[00:05] <Laurenceb> the centripetal accel unfolds it
[00:05] <SpeedEvil> Isn't the force on the gyro going to be quite large?
[00:05] <Laurenceb> yes
[00:06] <SpeedEvil> the force that is trying to make it skew off axis
[00:06] <Laurenceb> but it despins
[00:06] <Laurenceb> the moment of inertia increases so the spin rate decreases
[00:06] <Laurenceb> the moment of inertia of the pcb is made to be small
[00:06] <Laurenceb> this is another reason why there is the second motor
[00:07] <Laurenceb> so the second stage continues to spin at ~ the origional rate
[00:07] <SpeedEvil> ah - the gyro is despun when it's trying to do the torqueing
[00:07] <SpeedEvil> right
[00:07] <SpeedEvil> That makes more sense
[00:07] <Laurenceb> yes, thats key to making it work
[00:09] <Laurenceb> the fairing unfolds like petals, also under the action of the centripetal accel
[00:09] <Laurenceb> and that allows the gyro to unfold, and also gives the second stage a little kick to seperate it
[00:09] <SpeedEvil> and falls off?
[00:09] <SpeedEvil> (the fairing
[00:09] <Laurenceb> the tricky bit is to avoid contact between the fairing and gyro
[00:09] <Laurenceb> yes
[00:10] <Laurenceb> but you can test this on the ground
[00:10] <SpeedEvil> Can you?
[00:10] <SpeedEvil> Isn't the atmosphere going to be important?
[00:10] <Laurenceb> a bit
[00:10] <Laurenceb> you can at least get a good idea
[00:11] <Laurenceb> you may want to add mass to the fairing as its such low density
[00:11] <Laurenceb> - balsa with kapton film covering
[00:11] <SpeedEvil> what diameter is the second stage again?
[00:11] <SpeedEvil> oh
[00:11] <SpeedEvil> the fairing is what - 60mm?
[00:12] <SpeedEvil> The surface speed is only going to be 10m/s or so - which isn't too bad - but once it starts to unfold, the aero forces are quite large
[00:13] <SpeedEvil> I suppose to actually get it all unfolded and despun and such is going to take several seconds
[00:14] <SpeedEvil> before it even tries to start torquing
[00:14] <Laurenceb> yes
[00:14] <Laurenceb> as you need you get an idea of the spin axis first
[00:14] <Laurenceb> I was just thinking to test the seperation
[00:14] <SpeedEvil> I mean mechanically
[00:15] <SpeedEvil> so something like a drop vacuum chamber won't really work

[15:33] <fuzzylugnuts> hey, question for you guys
[15:35] <fuzzylugnuts> If I wanted to emulate a zero pressure balloon with a latex one, I would need to have a vent of some sort to vent lift gas and slow the accent rate to 0?
[15:35] <SpeedEvil> maybe
[15:36] <SpeedEvil> It's also seemingly possible to get 0 lift due to the balance of the elastic force on the balloon doing a mild superpressure effect
[15:36] <fuzzylugnuts> I'm sure that will play a part due to the elasticity of the balloon
[15:36] <SpeedEvil> If - round numbers - the internal pressure of the balloon is 1 millibar, the external is 4 millibars, then the total differential pressure is 3mB
[15:37] <fuzzylugnuts> :P no kidding
[15:37] <SpeedEvil> The balloon - neglecting elastic forces - continues to expand as it rises, rising at a constant rate
[15:37] <SpeedEvil> (ish)
[15:38] <SpeedEvil> If you fill it just the right amount, it ascends, but there is instead of a nice continuous constant lift due to altitude, it drops off to zero due to the elastic force
[15:38] <fuzzylugnuts> hmm
[15:39] <fuzzylugnuts> It seems that the point of neutral bouyancy is infinetly small due tot he balloons ability to expand, then
[15:39] <SpeedEvil> By making the balloon smaller, the elastic force adds a virtual weight that rises as it goes up
[15:39] <SpeedEvil> no - not quite
[15:39] <SpeedEvil> imagine for example a balloon with 10mB internal pressure
[15:40] <SpeedEvil> And say 50% of the total mass as free lift
[15:40] <SpeedEvil> It will ascend until the external pressure is something like 20mB or so, and then not ascend further
[15:41] <SpeedEvil> because though the balloon would indeed expand as it goes up - the internal pressure is rising faster than the external pressure is falling.
[15:41] <fuzzylugnuts> with latex balloons the differential pressure is so small though... the window of altitude that its neutrally bouyant would be tiny
[15:41] <SpeedEvil> Or rather - the internal effective density is rising faster than the external density
[15:41] <SpeedEvil> the numbers I did a while back - IIRC - indicated on the order of a millibar
[15:42] <fuzzylugnuts> yeah, thats pretty small
[15:42] <SpeedEvil> which - with an external atmosphere of 4mB - is quite significant
[15:43] <fuzzylugnuts> but at 35000ft, the pressure is 230ish mbar
[15:44] <SpeedEvil> 35000 is very low
[15:44] <fuzzylugnuts> Yah
[15:45] <SpeedEvil> At 34km forex - it's 6mB
[15:45] <SpeedEvil> I'd misremembered the pressure
[15:47] <fuzzylugnuts> even at 80kft the pressure is up down to 28mbar
[15:47] <fuzzylugnuts> So it would seem a latex balloon, even vented, would be quite impractical for neutral bouyancy
[15:49] <fuzzylugnuts> thats all I wanted to bounce off you guys
[15:52] <fuzzylugnuts> I'd like to mess around with ZP balloons sometime, but just don't have the time/facilities to build the balloon
[15:58] <rjharrison> fuzzylugnuts latex and neutral boyancy is cool
[15:58] <rjharrison> Need as you say a vent an ballast
[15:58] <rjharrison> and
[16:03] <fuzzylugnuts> luck
[16:03] <fuzzylugnuts> : )
[16:03] <fuzzylugnuts> I want to have a remotely operated vent on the balloon just to mess with it

[19:21] <rjharrison> Hendrix is the best

[19:24] <rjharrison> I'll set you up with an XML file when your closer
[19:24] <DanielRichman> cool
[19:24] <rjharrison> ie when you are no longer making changes :)
[19:25] <DanielRichman> It's pretty much final
[19:25] <DanielRichman> but yeah, ok
[19:25] <rjharrison> Needs about 24hr before launch an about 5 mins of test rtty t make sure it works
[19:25] <DanielRichman> can certainly be done
[19:26] <rjharrison> Save panics on the day and it relly nice to track
[19:26] <rjharrison> Will be tracking you on the day anyhow
[19:26] <DanielRichman> Awesome :)
[19:27] <rjharrison> If you have mobile internet and a gps device I have some linux code that will upload the chase car coors to the tracker too
[19:27] <DanielRichman> I do have both
[19:27] <DanielRichman> infact i have two mobile internetz
[19:28] <rjharrison> Great use one for live video during the launch :)
[19:28] <DanielRichman> As for the gps device, I should be able to get that.
[19:28] <sbasuita> DanielRichman, have you got a laptop to use yet?
[19:28] <DanielRichman> Live video, check
[19:28] <DanielRichman> sbasuita, use mine :X
[19:28] <sbasuita> DanielRichman, er no
[19:28] <sbasuita> DanielRichman, it will run out of battery

[19:28] <DanielRichman> Hmm.... I reckon I can acquire a laptop
[19:29] <sbasuita> DanielRichman, how about your brothers
[19:29] <rjharrison> there is a script there called track vi that to get an idea of how it works
[19:29] <sbasuita> DanielRichman, also did you get my forwarded mail about the money for foundation license?
[19:29] <rjharrison> Very simple but effective
[19:30] <DanielRichman> sbasuita, yeah.
[19:30] <DanielRichman> rjharrison, cool, thanks
[19:30] <rjharrison> DanielRichman if not I have a spare eee you can borrow on the day. Assuming you are going to do this on a w/e there is a good chance that I will be there
[19:31] <DanielRichman> sbasuita, if we have two laptops... one running windows and streaming live video, one doing the tracking etc.

[19:31] <DanielRichman> unless... how do you think we should stream?
[19:31] <sbasuita> DanielRichman, ustream.tv
[19:31] <DanielRichman> most online services use flash based webcam streaming which sucks for linux
[19:32] <rjharrison> ustream from windows
[19:32] <DanielRichman> exactly
[19:32] <DanielRichman> so unless you fancy running virtualbox or Xen (can you even Xen windows??) then we'll need two laptops
