I haven't checked the legislation in 15 years but I do remember model rocketry getting a lot of scrutiny in regards to their onboard control systems. They were only allowed very rudimentary controls if you had anything like in this video the feds would have probably locked you up for domestic terrorism and manufacturing guided missiles. Be very careful when even considering making something similar, check your locals laws and such and never assume good faith from law enforcement. Those days are long gone.

@@WarDucc Anything has a center of lift. It's the point where all integral aerodynamic forces are located. You know, the wing surfaces generate lift and drag - which are nothing but two components of a force vector. These local force vectors can be integrated over the entire craft (as any surface will create some drag, therefor an aerodynamic force) and you will have a vector that has a direction and an origin, and said origin is called the center of lift. Since lift forces are usually orders of magnitude bigger than drag forces (at least for high angle of attack configurations) we call this principle "Center of lift". It plays a crucial role in vehicle stability. A stable system will always try to orient the center of lift behind the center of mass for a moving object. The feathers on an arrow demonstrate that principle very well. You put them on the end to keep the arrows flight path straight. A slight deviation from the straight orientation will increase the angle of attack on the feathers and force the arrow back into a straight flight path. This means a deviation is met with a counteracting force and self balances the object. "Straight as an arrow" comes to mind. If you put the center of mass behind the center of lift, the opposite happens: A small change in angle will, again, create a force on the guiding surfaces of the vehicle. This force, however, is now acting in such a way that itself increases the angle of attack even further. This results in a larger force, finally flipping the vehicle such that the center of lift now is behind the center of mass. The thing about aerodynamics is, that lift and drag are functions of the Reynolds number. Changing flight conditions will result in changing aerodynamic forces. You need to account for all states of flight to ensure your vehicle is stable thoughout. Especially the transsonic regime is acting up, as many properties of airfoils change dramatically in this environment. I somehow doubt that this was a consideration on this project though. To conclude: Jettisoning the lower fins simply removes their aerodynamic forces from the overall integral of all force vectors. If you remove a vector far away from the center, it will effect the resulting position of the center significantly. The rocket basically turns the direction of the arrow mid flight - from having "small feathers" up front and "big feathers" in the back to only having "small feathers" in the front, making it the new rear of the arrow as it inverted.

@@WarDucc well, rockets have a center of lift and they are essentially oversized missiles. For missiles, center of lift isn't about generating enough lift to take flight, it's about keeping the missile stable during flight. If the center of lift is ahead of the center of mass in the direction the missile is moving, then the missile will attempt to invert itself, since the center of lift always tries to stay behind the center of mass for stability. To counteract that, missiles have fins on the rear that push the center of lift behind. However, when the missile is vertically falling and the parachute is installed on the nose, then the original design is very unideal, as the missile will now try to fall nose first to maintain stability. To counteract this, we need to push the center of lift further up the missile. The team here achieved this by jettisoning the fins, which pushes the center of lift further up so that the missile can fall thruster down.

The missile knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation. The guidance subsystem uses deviations to generate corrective commands to drive the missile from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't. In the event that the position that it is in is not the position that it wasn't, the system has acquired a variation, the variation being the difference between where the missile is, and where it wasn't. If variation is considered to be a significant factor, it too may be corrected by the GEA. However, the missile must also know where it was. The missile guidance computer scenario works as follows. Because a variation has modified some of the information the missile has obtained, it is not sure just where it is. However, it is sure where it isn't, within reason, and it knows where it was. It now subtracts where it should be from where it wasn't, or vice-versa, and by differentiating this from the algebraic sum of where it shouldn't be, and where it was, it is able to obtain the deviation and its variation, which is called error.

If it was that simple "algebraic sum" :) It should use some PID, because relation between how wings are adjusted and how should be set. Depends on various factors like for example speed or size of wings. Greater the speed lower the feedback should be, but not always if it would be too loow - SpaceX lost fuel, could not adjust it's position fast enough and fliped over. To not cause too much correction than necessary causing in consequence loosing it's trajectory in opposite direction - making it even worse. Simple PID should be set, to set P and I and D module properly you have to test it couple times. One to react quickly over-reacting, other integrating change add some "trim" and third simply multiply by some factor I hope you know all of this, just wrote for everyone else - it's not that simple, although more or less, way you described. Perfect algorithm would "learn" during long flight could gather information and subsequently adjust PID parameters to end up with minimal deviation. It's difficult if you deal with rocket.. to learn i hope they continue for example set goal of hiting target like baloon or something in the air :) That would be cool. First baloon with GPS attatched and both connected. Second time only visual. Private defence system :)

If they have explosives attached, then it is a little more complicated but still possible. Testing them can become a lot more complicated as there are FAA (surprisingly not ATF) regulations that prevent guided rocket testing without special permission. Guided meaning that it lands in a specific location. It’s a lot easier to design, test and deploy autonomous loitering munitions that do not use rocket motors, like the switchblade drones and the like, these days if you are a budding Tony Stark.

i mean id like that too but tbh i feel like such systems most likely fall under multiple countries regulations of weapon systems just like passive radar code and so son with the kraken SDR not sure if Japan has such regulations not to mention the huge amount of risk this would add for terror attacks and other things like assassinations which in japan are pretty on topic rn so i think the release of the code would be more unlikely, although this may be sweet to send the FSB a present from some activists in Russia this would be hecking sick for causing chaos inland russia

How can you just walk around with it at the park without making rocket noises and pretending it is flying???? That was some impressive self control, I would definitely be like "FSHHHHHHHHHHHHHFSHHHHFSHHHH!!!" every time I carried it around. Amazing project I am really impressed! Also if you do ever need someone to follow the rocket around wherever it goes making rocket noises, I am your man.

Did a laser guided model rocket back in the 80's with nowhere near the tech used here. Photodiodes and 741 op amps for the most part. Tube launched and two staged. Could hit within 4 feet of the aim point at 500 yards.

The missile knows where it is at all times. It knows this because it knows where it isn't, by subtracting where it is, from where it isn't, or where it isn't, from where it is, whichever is greater, it obtains a difference, or deviation. The guidance sub-system uses deviations to generate corrective commands to drive the missile from a position where it is, to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position where it was, is now the position that it isn't. In the event of the position that it is in is not the position that it wasn't, the system has required a variation. The variation being the difference between where the missile is, and where it wasn't. If variation is considered to be a significant factor, it too, may be corrected by the GEA. However, the missile must also know where it was. The missile guidance computance scenario works as follows: Because a variation has modified some of the information the missile has obtained, it is not sure just where it is, however it is sure where it isn't, within reason, and it knows where it was. It now subracts where it should be, from where it wasn't, or vice versa. By differentiating this from the algebraic sum og where it shouldn't be, and where it was. It is able to obtain a deviation, and a variation, which is called "air"

Hi,请问你们是如何计算惯性导航的? 我用 ICM20948 + esp32,100HZ,在matlab中 离线处理 CSV,使用 1阶 0.1hz 高通 filtfilt 后,效果挺不错。然而在 python里 实时处理 串口,使用 lfilter 效果就很不理想。 不是回弹太厉害就是 积分误差太大飞走了。 想学习学习啊!
