[09:06] <chimpusmaximus> Would love to but mine is in payload :-)
[09:11] <RealBorg> if he fails, i can recommend a hicopter pilot ;) https://www.youtube.com/watch?v=O5ElGt6iAYw
[09:12] <eroomde> helicopters should not be dismissed as impractical for hab experiments
[09:12] <eroomde> it was actually the cheapest way of doing a test we had to do once
[09:12] <chimpusmaximus> actually thinking about it i have a friend who can fly helicopters... mmmm
[09:12] <RealBorg> I dislike helicopters / quads - they are are awful waste of energy
[09:13] <eroomde> i'm not really sure how you can recreate what a helicopter does for much less energy RealBorg
[09:13] <eroomde> scaling up quads is stupid certainly
[09:13] <eroomde> but it's only proposed by futurists who have websites but don't understand physics
[09:14] <Oddstr13> now there's an idea
[09:14] <eroomde> 'imagine at an accident scene where a huge drone quadcopter can fly in and take you to a hospital immediately!!'
[09:14] <Oddstr13> a ballon-quad hybrid
[09:14] <eroomde> ... like a helicopter ambulance does already?
[09:15] <eroomde> Oddstr13: i think the quad would have a hard time fighting against the drag of the balloon
[09:15] <RealBorg> a balloon with propulsion could do almost everything a helicopter can at a fraction of the energy cost
[09:15] <eroomde> however there are some really nice airhip hydrid things around atm
[09:15] <eroomde> RealBorg: no it wouldn't
[09:15] <eroomde> that's just silly
[09:15] <eroomde> and i don't like silliness in this channel
[09:16] <Oddstr13> uh, well, a ballon probably won't be able to achieve the same speeds as a helicopter
[09:16] <RealBorg> at least its physically feasible
[09:17] <Oddstr13> you know what would be fun?
[09:17] <Oddstr13> a drone airplane with lidar
[09:18] <eroomde> it's not really physically feasible
[09:18] <eroomde> Oddstr13: yes i agree
[09:18] <eroomde> phoneix aerial make some nice stuff on youtube
[09:18] <eroomde> Oddstr13: a balloon helicopter would probably just achieve whatever the wind speed is
[09:19] <Oddstr13> Norway is actually getting mapped by lidar now, if I've understood things correctly
[09:19] <eroomde> RealBorg: you're basically just describing an airship, you realise. They can be a real pig to station-hold and do precise landing and manouvres
[09:19] <eroomde> they're alright at a big scale for getting stuff around slowly
[09:19] <eroomde> assuming the weather is good
[09:20] <eroomde> small ones are a pig - I've written autopilots for both quadcopters (easy) and airships - and airship, despite being more stable in attitude, are a real pig to negotioate with winds
[09:20] <eroomde> their drag coefficient is very strongly a function of angle of attack and the dynamic range is enormous
[09:21] <RealBorg> airplanes have undergone centuries of development
[09:21] <eroomde> like the Cd changes from 0.05 to about 0.4 depending on front-on vs side-on, and the overal area side-on is about 6-7 times bigger
[09:21] <eroomde> so you end up with about 100:1 different
[09:21] <eroomde> RealBorg: yes. also daffodils are yellow. what's your point?
[09:22] <RealBorg> airships have not seen much innovation during the times of cheap fuel
[09:22] <RealBorg> but they are becoming increasingly attractive
[09:22] <eroomde> there's research going into heavier-than-air ones currently, and yes that's interesting
[09:22] <eroomde> but i don't think that's so much for absolute energy efficiency as some tactical advantages for a current style of warfare
[09:23] <eroomde> hence most of the work only going into short-runway troop+light vehicle transport
[09:23] <RealBorg> I think at some point we will see a fusion of google's high altitude balloons and facebooks high altitude drones
[09:24] <eroomde> maybe you should go to hacker news instead of here
[09:24] <eroomde> that's more your level
[09:24] <RealBorg> #futurology could be appropiate
[09:24] <eroomde> yes
[09:24] <eroomde> but here we're sort of more into science and quantitative understandings of things
[09:24] <RealBorg> a very conservative statement
[09:25] <eroomde> you can afford to not be conservative when you don't actually make anything
[09:25] FuzzyLemon (4d59ae57@gateway/web/freenode/ip.77.89.174.87) joined #highaltitude.
[09:25] <eroomde> but in my position, where I actually am working on the future of how to transport stuff, you have to understand your thermodynamics. Otherwise you can't do engineering.
[09:28] <RealBorg> remember that humanity made most progress when it set out to accomplish things considered impossible at that time
[09:29] <eroomde> yes, that's called survivor bias
[09:29] <eroomde> there are a thousand loons on a futurology irc channel for every one person who managed to make something impressive
[09:30] <gonzo_> usually seeded by an engineer who has more info/understanding/idea that no-one else had had
[09:30] <gonzo_> yet
[09:30] <eroomde> and i dispute that most of the great accomplishments have been considered impossible. Like, i would consider perpetual motion to be impossible, just from a fundamental physics point of view, but i wouldn't consider slightly more efficient ways of transporting cargo to be worthy of your kind of grandiose staement about humanity
[09:31] <RealBorg> https://www.youtube.com/watch?v=wnkEace3rb4 http://m.imdb.com/title/tt0118884/quotes?qt=qt0379353
[09:32] <gonzo_> there was a BBC prog about the diesel engine and it's effect of civilisation
[09:32] <gonzo_> though that was an invention heavilly based in knowledge of thermodynamics
[09:32] <eroomde> RealBorg: you're quoting some scifi at me
[09:32] <RealBorg> and always remember: there are no cheats and backdoors in reality
[09:32] <eroomde> what do you do?
[09:32] <RealBorg> like free energy, antigravity,...
[09:32] <eroomde> are you an engineer of a scientist working on this stuff for real?
[09:35] <eroomde> not that that's necessary to have good ideas (and i'm sure you have an anecdote about a patent clerk read and waiting to give me) but I can't tell if you're like a wise old greybeard who's seen and done some stuff or just a random internet punter who 'reckons' x or y will be the future
[09:37] <RealBorg> looking in the mirror i can confirm the grey beard
[09:38] <eroomde> well, all i can say is that i agree that great things are possible, but it's really helpful to know just enough physics to be able to work out on the back of an envelope if something makes sense, energetically, or not, before diving in with a real experiment
[09:38] <Oddstr13> eroomde: awesome, I want a TerraHawk T-32!
[09:39] <Oddstr13> buy me one plz :P
[09:39] <eroomde> the stuff i work on could be revolutionary if it works, but a 1% hit on specific impulse can make the whole idea collapse, and not get you to orbit, jsut because of the nature of the physics that governs, say, getting into orbit
[09:39] <eroomde> you really have to have a quantitative understanding to actually get anywhere, otherwise you're flailing
[09:40] <RealBorg> the wright brothers didn't make a transcontinental flight on their first attempt

[09:41] <eroomde> sure, let's make a space rocket that doesn't quite get into orbit
[09:41] <eroomde> that'd be a noble ambition
[09:41] <RealBorg> showing that the ceiling of both balloons and aerodynamic flight could be greatly expanded with lighter than air vehicles would be an appropiate "first flight"
[09:41] <eroomde> when the people who put ten billion euros into it ask why we messed up i'll just send them some quotes
[09:41] <eroomde> 'rome wasn't built in a day'
[09:42] <eroomde> 'you can't make an omlette without breaking some eggs'
[09:42] <RealBorg> I'm not trying to build a rocket, it will cost nowhere near billions and i am spending my own money
[09:42] <eroomde> what are you trying to do?
[09:42] <eroomde> this might help me understand what on earth you're talking about
[09:43] <RealBorg> i told you about my balloon + solar electric propulsion idea
[09:43] <eroomde> remind me
[09:45] <RealBorg> i want to send up a balloon with solar cells and electrohydrodynamic propulsion

[10:15] <RealBorg> that's on my project plan
[10:17] <RealBorg> evaluate the performance and possible modifications for the propulsion
[10:18] <eroomde> what sort of thrust/power do you get, roughly, at altitude?
[10:23] <RealBorg> ~10mN/W
[10:25] Nick change: Guest75510 -> pjm
[10:28] <eroomde> ok well good luck
[10:29] <eroomde> just doing some napkin sums, say you go to 30km altitude with a balloon, we'll take a 1kg balloon with a couple of kg of payload, at 30km that has a dimaeter of about 10m, roughly
[10:29] <eroomde> assuming you want to go at about a walking pace, say 2m/s
[10:30] <eroomde> with a drag coeffcient of 0.5 on the balloon at that diameter, and a denisty of about 0.02kg/m^3 at altitude, to go at that speed gives you a drag of about 1.6N
[10:31] <eroomde> so that requires 160W of power
[10:31] <eroomde> which is a lot
[10:34] <RealBorg> I am currently trying to optimize that value
[10:34] <RealBorg> have you considered that lower air density causes lower friction?
[10:34] <eroomde> please read what i wrote
[10:35] <eroomde> ", and a denisty of
[10:35] <eroomde> about 0.02kg/m^3 at altitude,"
[10:35] <RealBorg> sorry
[10:36] <RealBorg> the point should have been the lower drag coefficient of an airship (shape)
[10:36] <eroomde> ah no, i modelled it as a balloon
[10:36] <eroomde> an airship shape will certainly help
[10:37] <eroomde> tricky to consutrct something to take a shape like that with a significant payload, though
[10:39] <RealBorg> you know the "cheap" metalized helium balloons for kids?
[10:39] <eroomde> yep
[10:41] <RealBorg> such foil could be used to shape the inflated airship - just like an air mattress
[10:42] <RealBorg> did you know the goodyear inflatoplane?
[10:42] <eroomde> so you mean some sort of inner bladder with an outer structural skin
[10:43] <eroomde> i've heard of the inflatoplane
[10:43] <eroomde> i realise i've made an assumption here - is this designed to fly at high alt or lower down?
[10:45] <RealBorg> high alt
[10:45] <eroomde> right
[10:45] <RealBorg> but if inflated with a mi of helium and air it should be able to fly at low altitudes as well
[10:45] <eroomde> sure
[10:46] <eroomde> though if it was the same size the drag would be that much higher
[10:46] <RealBorg> but the basic idea is: there is no simulator for high altitude (flight)
[10:46] <eroomde> of the order of 100x at sea level, requiring 16kW
[10:46] <eroomde> well, less if an airshape shape i guess

[11:38] <FuzzyLemon> if you are launching 2 balloons together, do you need 2 chase cars?
[11:39] <eroomde> depends on how much you back yourself
[11:40] <FuzzyLemon> If they have very similar ascent rates then they shouldnt land too far apart should they?
[11:41] <FuzzyLemon> and similar parachutes
[11:41] <fsphil> the burst altitude can have a large effect on the landing position, depending on the winds
[11:41] <FuzzyLemon> I'm trying to think about the extra considerations required when launching 2 balloons
[11:43] <FuzzyLemon> normally i try and be as close as possible to the landing site when it's descending, but when there's 2 balloons what is one to do?
[11:43] <fsphil> two chase cars, ideally :)
[11:44] <fsphil> or just go for the nearest one first
[11:44] Nick change: fl_0 -> fl_0|afk
[11:45] <fsphil> maybe just get the final landing position. if you know it's secure, head on to the second
[11:45] <FuzzyLemon> also would you need 2 radios if you wanted to track them simultaneously?
[11:46] <daveake> Well I'm doing 3 on Saturday, and I'm going out in 1 chase car, and then only after they've landed
[11:46] <fsphil> normally yeah
[11:46] <daveake> But they are cheap trackers so meh if I lose 1 or all of them
[11:46] <FuzzyLemon> i really don't want to lose any
[11:46] <daveake> Yes for rtty and a "real" radio you need 1 radio per payload ideally
[11:47] <daveake> An Airspy or similar can be set up to receive several payloads simultaneously
[11:47] <gonzo_> if you can get the tx stable enough, and both stay within an audio bandwidth, you could decpde two. But risky

[11:50] <RealBorg> they claim to have achieved 100n/kW
[11:50] <craag> with some very careful freq alignment, yes FuzzyLemon
[11:52] <FuzzyLemon> but wouldn't it decode the 2 signals together in a mashed up jumble?
[11:53] <FuzzyLemon> *if you are using dl-fldigi?
[11:53] <daveake> You can run 2 copies of dl-fldigi, one per tracker
[11:53] <gonzo_> FuzzyLemon, if you keep the shift (between the two freqs of each tx) narrow. Then you could program to two payloads to be , say 1khz apart?
[11:53] <gonzo_> then you can hear both signals and set up two instances of fldigi
[11:54] <gonzo_> as long as the two signals don't drift into each other, you shoulkd be ok

[11:59] <mfa298> FuzzyLemon: if the tracking PC is windows you can use sdr radio/console to receive multiple payloads if they're in the bandwidth of the dongle (192khz for FCD Pro+, 8MHz ? for Airspy)
[11:59] <MickMondo> yeah I did .. its M6FSU
[11:59] Action: mfa298 reads some scrollback
[11:59] <UpuWork> congrats :)
[11:59] <craag> Well done MickMondo
[11:59] <UpuWork> just need to get FuzzyLemon through next year :)
[11:59] <craag> Sorry about delays n stuff
[12:00] <MickMondo> thanks,,, not a problem at all
[12:00] <UpuWork> You will need to grow a beard though FuzzyLemon
[12:00] <craag> haha
[12:01] <MickMondo> any plans to do intermediate ..?
[12:02] <craag> next year?... maybe. It's a bit more fuss beforehand but we've done it before.
[12:02] <UpuWork> We have done intermediate before
[12:02] <UpuWork> we can't do Advanced
[12:02] <craag> advanced has to be on certain dates
[12:03] <MickMondo> ahhh, just a thought
[12:03] <MickMondo> I'm right in saying you need advanced to do mobile WSPR ..yes
[12:03] <craag> yeah, we'll talk about it nearer the time :)
[12:03] <craag> mobile wspr?
[12:03] <MickMondo> OK...
[12:03] <MickMondo> yeah on a balloon
[12:04] <craag> ah
[12:04] <MickMondo> the transmitter is mobile
[12:04] <craag> yes, as you're operating aborad
[12:04] <craag> *abroad
[12:04] <craag> nothing to do with being mobile
[12:04] <MickMondo> yeah thats what I thought
[12:04] <FuzzyLemon> hey i did at least 4 'surprise' flights without local telemetry and without a beard. Only one completely screwed up
[12:04] <craag> so you're using the CEPT agreement in every country you transmit in
[12:04] <UpuWork> lol
[12:04] <MickMondo> yeah
[12:05] <UpuWork> So yeah FuzzyLemon they should land closeish, they will burst at slightly different times so you should be able to be in the area, get a final on one, go get the final on another and then go get them
[12:06] <MickMondo> Cheers Guys ....

[12:14] <eroomde> FuzzyLemon: we've done multi flights before and recovered fine. So long as the telemetry is all solid it's fine. Obviously much easier if you can match the fills closely so they end up landing near each other
[12:14] <eroomde> on my icom radio i programmed each payload into its own memory slot so i could jump between them easily
[12:16] <chris_99> if you're launching two ballons, i guess you use different frequencies for each?
[12:19] <daveake> Yes, you can separate them by frequency, or by time (e.g. my flights this weekend take turns tx-ing on the same frequency)
[12:21] <chris_99> yeah i was thinking about by time, how do you do that though, do they have a RTC on?
[12:21] <daveake> GPS
[12:21] <chris_99> ah doh
[12:21] <chris_99> makes sense
[12:21] <chris_99> heh

[12:25] MoALTz (~no@78.11.179.104) left irc: Ping timeout: 244 seconds
[12:25] <chris_99> just do what daveake said, use the GPS time signal so one transmits a bit later than the other
[12:26] <craag> not ideal with rtty though
[12:26] <chris_99> why?
[12:26] <chris_99> if you know what the maximum length transmitted is
[12:27] <craag> turning on and off will lose a bit of dl-fldigi to relock each time, and if the frequencies are slightly different, dl-fldigi won't lock on
[12:27] <chris_99> ahh

[12:29] Nick change: fl_0 -> fl_0|afk
[12:30] <daveake> yeah it's a dl-fldigi limitation not an rtty one
[12:31] <daveake> aprs, lora and ukhasnet manage just fine
[12:31] <craag> yep, with a long enough '$$$' you might mitigate both of those issues with matt's decoder
[12:31] <daveake> yes
[12:31] <RealBorg> you could split by time and feed fldigi only one stream at a time
[12:32] <craag> not sure what you mean RealBorg
[12:33] <RealBorg> fldigi decodes an audio file, correct?
[12:33] <craag> err I believe it can yes (or you can play it into it)
[12:33] <RealBorg> so you could use any audio software to split the audio file based on time index
[12:34] <craag> right
[12:34] <craag> but in the chasecar?
[12:34] <RealBorg> and feed fldigi the file of probe1 and then the file of probe2

[12:36] <craag> I can't see how that solves anything
[12:36] <daveake> There are 2 problems; one is that each tracker will be on a different frequency, and dl-fldigi's AFC will likely not switch from one to the other. The second is that dl-fldigi's AFC will tend to drift off in the absence of a signal.
[12:36] {^TIBS01^} (tibs01@5751bf78.skybroadband.com) joined #highaltitude.
[12:36] <daveake> To fix these you would need to construct 2 separate continuous signals

[12:37] <craag> +1
[12:37] Nick change: BitEvil -> SpeedEvil
[12:38] <craag> you want least complexity in the chasecar really
[12:38] <daveake> Given enough $$$$'s at the start of each sentence, I'm sure that Matt's decoder would work fine
[12:40] <fsphil> you need to bribe it?
[12:41] <chris_99> haha
[12:42] <daveake> Call it compensation
[12:43] <mattbrejza> it actually only needs one $
