SSF-2

@TritonAerospace not really

@EhsanA yeah i made some but I still didn't make a guidance law for them

Do you also work on ballistic missiles?
that is incredible

@Samps0n yeah I've increased the limit of thrusting at slower speeds and can do some wild alignment maneuvers now thanks to PD, for example like a thrust vectored main engine can do a cool initial alignment like the Russain Sams.
And minimum range has probably drastically decreased.

@Samps0n man that is wildest error ever!!
Somehow something went wrong, the other thrusters were supposed to push down and align specially easier with low speed.
No worries man. It was just a little hard to keep up with the way you were explaining things.
I thought you were chinese or japanese for a moment but then again you spoke different from them lol.
I'm gonna tune it a little bit then release.

English is my third language although I've mastered it by now.

Thats incredible. I have never targeted anything that close, are the thrusters putting out more than they do in my model? Because my 720° missile could of hit it is it was like the one in the video

I got a video for you. I didn’t start it until it overshot a 643km target, this time tho it bank hard right and from the point the video begins your missile banking 720° to hit the target but it is so on top of the target it can’t quite make it. As for me I got c- in English 101(English comp) an A in english100(creative writing) but I am an American that lives in Melb, Australia for about a decade. Aussies are very lazy with their English and it does rub off no matter how hard I try. Is English your second language? I didn’t realize that and I could talk with less regional slang etc. usually my slang would only be American , I’d have to be here long than 10y to speak thier slang.

This is the same missile type I told you the other day overshot 1100lm shot and kept flying straight . It’s so odd that it can make such drastic difference in its decisions from one time to the next. I will be on your newest missile right away, when it coming out of testing
Slowmo 1/4 speed in the video

@Samps0n check This Video i upgraded rocket and installed a derivative now observe at the beginning how it thrusts hard to align but doesn't overshoot and stops before it reaches alignment gradually.

@Samps0n where are you from?
I'm sorry but your english is really hard to comprehend .

Thanks, when I said missiles I meant the whole system, there is another guy that had the aegis land based setup and it was the first time I ever realized that they use the control thrusters, it was real clean 90° to horizontal the another thruster to stop. I bet the us gov only puts the 2thruster accounting for the roll by shear mass and having the burns only right out of the gate. Or do they use the thrusters for horizontal adjustments as well? I would think when it’s high or fast you would need them and/or gimballing… do m/any missiles gimbal?

What’s canallism? In reference to Chinese SAMs

@Samps0n there is an interesting site that has a whole database and description of missiles it called Missilery

That make sense I have also gotten the thrusters to go farther. I know that you weren’t meaning that you programmed them to take the high g turns but that you were telling me in RL but I tried it by turning off the thuster until it would overshoot, I think it was gonna try to go around(droo) again, not sure.ty for filling me in, you have actually got me looking at missiles lately, got any .com addresses you recommend?

@Samps0n the older missiles also had frontal fins and were basically the same design except it was just shit at intercepting anything above 12km or above 300m/s so i added thrusters and changed guidance law

The older launch tube missile, I think in the solo launcher, it didn’t have the thrusters, yet it behaves the same as the ones that do, what’s going on there, they doing different things or the thruster is a lot of show? That’s an enormous amout of lift but whT do you think is the radius of a 20g turn at those speeds? I marine it is still quite large considering it wouldn’t take much to generate tho msg g’s at those speeds

@Samps0n oh you mean the crazy turn ability of those thrusters?
Yeah the thruster plume is also 2/3 the length of the missile yeah you can't change much about the older engines plume.

Yes i checked online for similar real life missiles they do about 20G turns at >mach 5 which i tried to model after my missile.
it turns a little sharper than real life, But it could be tweaked.
Also the front fins are what is providing the lift to turn the missile.
In real life the missile uses no frontal fins and uses body lift instead to turn with gas thrusters but airflow isn't simulated in Juno so.

The early missiles that you say got <1km at 75km were differently tuned, all in all a Derivative will fix the over compensation.

@Samps0n i have no idea what you mean.

About the missile's oscillation at altitudes >30km, that is due to a lack of a control loop.
I'm just plugging in the error feeback with proportional control and it needs a derivative to get those oscillations under control but i didn't go with that since i didn't want to spend days developing this missile system.

@TritonAerospace I got you, but what is the boost glide like the saf, series they aren't exoatmospheric the thing missile wouldn't make a 180°, or even45°turn with those thrusters would it? That doesn't make sense if so, that would imply to me that it's inertia from boost was using the wings(did you once say that the front fins, undeployed had the lift that was impressive? I was left thinking they had equal ctiticality for lift) you got lift from fins/thrusters generating up to <3x the thrust from the boost phase, but if it's momentum is small I would say it behaves more ballistic than like a boost powered cruise missile? Or is there a grey area?

There was the time that I got just under1km to a target a balloon falling from 75 km and now when I clear <45km it goes into this feedback of timing and overcompensation. I was thinking that the autopilot controls do not tweak the thruster response is what your experience is too? Well if we just took that over cranking ability of those thrusters. If normal operations is a ten this is at least 50-70 to’140 I’d say, arch’s 2/3 the length of the missile, what if you made it stay under , say 40, then this harmonic resonance that always end with me having tbruster sending me out of earth w/ escape velocity , wouldn’t that most likely kill the timing issues

Do real rcs and gyros that think harder than this sandbox using some smart chips, does it get told more conservatively when… a gyro will race to get to the point you set and not think to stopping till it overshoots and it seems to reverse gears and repeat ever decreasing amounts, they aren’t that energy intensive in reality would you think?

I’m sleepy I can’t proofread this any more, hope it’s not idiotic

@Samps0n it is because of the guidance type, it is different than normal atmospheric guidance.
In our case we have the exact coordinates of a target but then if we go ballistic the target rotates out of impact point due to earth rotation and so to counter that you have to dynamically compensate at the boost stage and aim ahead or behind the target, anticipating the rotation it will get then send it on a tangential vector to the target.

this will take me a whole week of studying and researching if i want to make it but i think i can.
I haven't studied it yet so that is why i largely now nothing about it.

@TritonAerospace how is that so, is it because the control ends at launch? I would think your ssm-25 or saf3a/b . I had been considering the complexities to it I think the way to simplify the program if they ran a polar direction orbit tho that could vary by then that limits the Δv needed to anywhere by allot if you have to go east , and I think it would be easier to send a missile once around polar before it would to try to fly east or west or by some 2000km. I know it’s by matter of quickness that the USA/ussr had their warheads over the artic tho that maybe of simplified earlier tracking systems needed that simplification , or is it, sometime another set of eyes helps pros Cree a different solution, hope I help

@Northwestkings could you upload the sandbox with the target and all?

@Samps0n about ballistic missiles... this craft was my first attempt at creating a ballistic rocket somewhat.
It is not as easy as it looks ballistic missiles are hard to make even for me it requires some tedious calculations.
I'm currently not trying but in the future i may make one.

@Samps0n hey man sorry didn't mean to upset you 😄 pls forgive.
I was working on improving it and adding fail safes to not explode near the launch vehicle and making it more realistic and slower & added flightlog tracking & new features.
I will upload current version soon

I thought I had told you that they are working again with the beta release, didn’t I? @tritonaerospace

You removed my favorites ? Did I piss you off? I am heartbroken, i got a new mobile and con blow up nothing now! When I started I despised the ppl that made weapons, but then to see the art behind your magic totally is a different thing. I meant to ask you, do you know of a ICBM that uses vizzy that would make a CEP of 1500m-ish ? Considering the complexities of what your hitting that a ballistic arch would be doable. I figured you would at least know what to expect

Whatever is going on with the new update , neither this one or the SAF-3b v2 has been launching for me. I will make sure that I have no repeats too but unless I edit this then you can trust that something has happened that undid your fix, fyi the saf-3a works but not this one or the saf-3b v2
