@Insanity lol no man, I kill the damn thing and all its running component from the task window that shows memory usage...etc. the problem is missing some updates and inability to sync cloud, so I open it occasionally
@SmurfResearchX I did exactly like you many times, seeking less weight with smaller engines but giving them a start by solid rocket boosters. But if no solid boosters, I'll use high TWR around 1.8 which seems to be high for many players. In this contest , the 2.5 TWR did better than the 1.5 check my latest craft you'll find them
@Jaime731 use whatever evaluation program that works better for you, the program is affected by the way we do staging . Regarding showing results, I'm not sure yet if to upload the aircraft or do a video or I don't know lol. Would love to hear if you have any ideas
@Kell apparently throttling down at certain point saves fuel. But if throttling down is similar to having low TWR , how come the high TWR rocket saves fuel more
@Teague suicide burn is an easy 2 lines only, if you have discord or skype we can chat over it. if it took off, flipped and landed tail first then my vizzy can be applied to it . here's the video
i made a vizzy program that worked from free fall until landing right in the middle of OISLY and others (Noname101) used the same program to land it from orbit on a smaller ship. i would like to help. i don't know much about starship though.
the only problem is that the center of body lift is located right on the CG , meaning that when fuel is consumed, the center of lift drops down along with CG and there will be no torque arm to flip the craft to it's expected position, there will be tinkering and adding fins that don't exist in reality in order to compensate for that CG/CL issue
@AnotherFireFox yeah although I can't say if it's only inputs. Maybe information as well, I don't know. Usually I research when I stumble with a hick up but this one just freaked me out. But I know at some points we'll have to have 2 working programs with close proximity, God be with us then
@AnotherFireFox I get the concept, let gravity turn the vehicle while being prograde and the video says pitch down from prograde when the air is thin, that's kinda loose instructions
@Dogfish5550
The rocket will be 2 stages for compensating atmospheric pressure change. I think the rocket will be only 7 parts
2 tanks + 2 engines + command pod, parachute and interstage
The only thing that participants can change in each rocket is the gyro power
@Rizkyman that sounds efficient to have prograde all time for less project area drag. But the problem is if you followed prograde, the pitch will never drop to zero, it will halt at certain angle.
@AnotherFireFox
You nailed it, this works.
I needed this time to multiply by lateral speed to predict the current estimated touchdown point for the rocket/projectile and compare that with the actual lateral distance to feed the fins controls. I'll use the vertical component of acceleration given by vizzy, not the planet's gravity as that acceleration is the net acceleration that takes out deceleration produced by air drag. My current guided landing uses linear (AGL ÷ vertical v × lateral speed) and kinda work well but I wanna do it more properly. Thank you
where can i update this, i'm on the experimental and no update there under v0.9 ..let alone v0.9.1. i'm not big on steam...
... Now i switched from experimental to beta testing and have 9.1 .. but what about the experimental ?? ugh i'm lost
I can hardly work with the current coordinates to work out my craft's position or target position in relation to Droo, but I've seen somewhere "planet" information so I guess those would be in relation to the sun and might be useful for what you planning to do, enter planetary automated travel? I've done the Luna but killed the idea of Mars when it tried to knock my head's door 😂, still not for me but I'd be happy if you assign a certain job/portion of it for me
For me, I never needed that kind of engines, I think 1% or even up to 3% of thrust words great especially if used in puffs, I get apogee and perigee with less than 300m or extend my apogee to Luna orbit with +- 500 m (out of 36,500,000 m) but if you need better find tuning then maybe you can use RCS with lowered power
I used to worry about that, but I realised air drag and mass reduction due to consuming fuel will do more than compensation for the delayed full throttle. So unless you're using really big engines and in vacuum environment. Don't worry about it. Otherwise, set slow motion and put full thrust while the engine panel is open, see how long it takes and divide by the slow motion rate then maybe divide by 2 (if it takes 2 seconds to reach full throttle, I'd count 1 second only since it wasn't dead during those 2 seconds)
@DeboStreams looks like you got a serious task...fixing my craft that's supposed to do guided landing. it's just a first stage with 4 fins. it keeps swinging with program orders. if you already have a stable model then it's ok and the credit goes to you either ways
@AnotherFireFox
I kinda agree with that, I even believe that philosophy "put the row data and let the players use it how they like" . I'm struggling for 2 days now to calculate my horizontal and vertical course angle through the vectors but I don't wanna complain because the difficulty is mostly due to my math abilities, it would have been better if those angles were there in the information section, it wouldn't make the game silly easy, we still have lots of tough tasks after that (in my case, comparing those 2 angles with a grounded target bearing angles for automated guided landing)
i think all what you mentioned can be obtained through new vizzy, unless i misunderstood you. and even if things are missing, this shouldn't stop you from enjoying the game. Before new vizzy there was no way to know target direction to perform automated docking but i used pitch input to get indication of where's the target in relation to prograde until the Dev heard the so many calls and put the update
I always thought of it. I have moving parts inside my craft (changing orientation of the command chip) and always had to remove the fairings/interstage to see if they're working as planned
@AndrewGarrison Nothing to be concerned for, it's just "gravity" was only a value and after update it was replaced by vector which my programs wasn't based on.
It's really awesome, enabled me to do the Launch-rendezvous-Dock mission 3 in one fully automated https://www.simplerockets.com/Videos/View/53797
@swope
Thanks a lot for your patience and help, I did it :) , timed launch, rendezvous and dock (orbital mechanics avoided)
https://www.simplerockets.com/Videos/View/53797
@swope AGL / MSL block is only for my craft , the problem is with the target MSL , if PCI target position returns the distance from the center of planet then bingo...and I have no problem and would be no need for this post . I'll confirm and get back to you
@swope oh OK, well I only wanted the MSL from that conversion, that's for the vertical alignment. For lateral alignment I use the "Y" element from the position (without the conversion of Lat/long/...) . It's not exactly an a to zee rendezvous, because as I told you it's only couple of kilometers separation that I intend to cover in ~100 seconds so whatever mess I'll put into my orbit I'll revert it back before it's irreversible. Now you said something about PCI , planet coordinate inertial ? Like coordinates from the center of planet? If that's the case then wow but I think it's not, the zero point of that coordinate system seems to be somewhere else, I did tested it.
@swope oh man, i read your request there, i hardly understand 5% of it, too advanced for me. i hope you get my point of Lat/Long/MSL or help me if there's a way for rendezvous using simple math (no orbital mechanics required as i have a launch system that puts the craft in orbit within 2km from the station)
@swope i don't want to use AGL for rendezvous, it's my complain here that it's AGL instead of MSL , MSL is required to know the other Dock port altitude. The other units (position using PCI) are not using the planet's center for reference as the Lat,long, AGL so it doesn't return height, it's good only for it's y axis (meters above/below the ecliptic)
@Bmcclory i was referring to the craft position vector when converted to Lat,long,AGL in new vizzy, it's a fixed conversion order, I wish it had a selector between AGL and MSL
@huuminberd I don't have anything that says "Experimental" in the beta section in properties, I did try to put "experimental" in the check code but also came invalid !!! This sucks

4.8 years ago@NoIDontWanna what's the gyro settings command?
4.8 years ago@AnotherFireFox so in short the shuttle starts pitching down from the beginning regardless to atmospheric density and no prograde ?
4.8 years ago@AnotherFireFox I get the concept, let gravity turn the vehicle while being prograde and the video says pitch down from prograde when the air is thin, that's kinda loose instructions
4.8 years agoNow you force another question, when do we exit the prograde and force pitch close to zero before wasting too much thrust on the vertical component ?
