has anyone heard of the new mach 5 missiles? they do not use a warhead of any kind. the way they work is they have a uranium core (not to try to gain a nuclear blast, but because uranium is supposedly very dense) that on impact, keeping in mind this thing is hurling itself through the air at 5 times the speed of sound, vaporizes the target and itself. apparently, between the pressure wave and the actual impact, almost nothing can escape vaporization. My question is does anyone have any idea what kind of propellant these things use? i believe, and also my dad who designs missle guidence system test equipment, that it is a mixture of ammonium nitrate, magnesium, a binder and a resin. These propellants are also used in Sidewinders and Patriot missiles fyi. If this is the type of propellant used, it would have to burn extremely fast. Anyone have any ideas as to the composition of this faster than sound marvel? |

Although impressive, these particular anti-ballistic missiles are not that effective, and are very costly to operate. Information about the propellant formula is available all throughout the internet. I would recommend ordering CP Technologies' book/video/software bundle www.space-rockets.com . 60bucks is a small price to pay for pre proven information that could save yourself from injury as the result of inexperience. Think about this when your thinking about mach 5 missiles, in order to exit the gravity of the earth, all rockets bound for space must go several miles a second. |

I ran across a patent once that used regular smokeless powder to propell a rocket to mach 5, or faster than 1 mile per second. The powder was loose inside the rocket casing and burned almost instantly. The casing was very strong of course. Not something you could duplicate at home. ------------------ |

That's called propelled cannon. |

I went through my old CD files and found the patent. Go her e to see the patent and links to the patent drawings of the rockets. I don't know what you're referring to by "propelled cannon" but it isn't these rockets. ------------------ [This message has been edited by nbk2000 (edited March 06, 2000).] |

Yea, those rockets are kicked out by the ignition and not burning on the path, that's why it's called cannon, and the high speed is due to the nozzle. Propelled cannon. |

Look up the definition of "rocket" and "cannon". A cannon propels a projectile by combustion outside of the projectile, a rocket by combustion inside the projectile. Cannons have recoil, rockets do not. It doesn't matter how long or short the combustion takes place, or if it takes place in the barrel. What matters is where the combustion takes place, inside or outside of the projectile. ------------------ |

Doesn't make any difference by tracing the definition. The igniton and burning combined is the same as a burst in the cannon, yet the rocket functions without a barrel, and gas is blasting through the nozzle to propell the shell. It IS POSSIBLE to reproduce the shell on a smaller scale since it only have to stand 50000psi, which is only about 2X the pressure of a .22 LR. Take a thicker(than a bigbore rifle barrel) steel tube, make a shell and get it cryo'd, you bet it will stand 50000psi. For the detailed part, a small machine shop can handle it more than adequate. The reason these shells can't go with ordinary explosive warheads is that at an acceleration of 10000fps, explosives can't merely stand the shockwave of the initial burst. |

The motor case and nozzle assembly are preferably made of a material having a high strength/weight ratio in order to withstand the relatively high internal chamber pressures and to increase the mass fraction. The patent says that the motor casing needs to be made out of the following type of materials. "Typical such materials are high strength resin matrix graphite and glass fiber composites, 6-4 titanium alloy, 17-4 PH precipitation hardening steel or 300 grade maraging steel. The graphite and fiberglass composites are, however, preferred because the resulting motor case will weigh less for the same chamber pressure." Titanium alloys and graphite composites are NOT common, easily obtained, inexpensive materials to use. Not something the home experimenter can fuck with. Not without a LOT of money. I suppose you could use steel that's been cryoed, but would it still be light enough to fly? And the .22 comparison is silly. The .22 casing doesn't have to withstand the pressure since it's supported by the gun barrel. The rocket has to not only withstand the pressure, but also the heat of the burning propellant, force of acceleration, and still be light enough to fly. The acceleration of the rocket may be 20,000 G, but artillery shells do that all the time. Explosive warheads are useable. But with tolerances beyond the average pyro. Oh, one last thing. This isn't a "propelled cannon" (whatever the fuck that's supposed to be), it's a rocket. Look at the patents title. Enough said. ------------------ |

You bet you don't have any idea what a graphite/glass fiber composite is, it's the material of "SYNTHETIC GUNSTOCK", you are more silly to think that anyone will use ".22 case" to stand 20000psi.(what is the chamber for? barbeque?) You are just too used to deter people from doing things you haven't think of or things you don't have knowledge to talk about (painful eh?), that you don't use common sense to really evaluate the possibility to BTW in your precious patend, it said the shell is relatively inexpensive to make. For the name, if it makes you feel bad or anything just say it, the patend of Glock pistol didn't say it's a "Glock" in the patend neither. You do believe artilleries have a initial 10000~fps=3.3~km/s, and the minimal velocity [This message has been edited by HMTD Factory (edited March 07, 2000).] |

Everything comes down to practicality, and what you wish to do. Gauss rifles are not very practical, but I am working on them anyways. Maybe even in the hopes of making them practical. |

First of all, fool, you should realize how expensive REAL graphite composite anythings cost. Your thinking of the common, cheap fiberglass composite. I said "The .22 casing doesn't have to withstand the pressure since it's supported by the gun barrel." To use your own words "you are more silly to think that anyone will use ".22 case" to stand 20000psi.(what is the chamber BTW, if you read the whole patent, you might realize that "relatively inexpensive" is being used when comparing the cost to $50,000 ATGMs. If it cost $1,000 per rocket, that is "relatively inexpensive" in military terms, but could YOU afford it? And that's in mass manufactured quantities. And your right, the Glock Patent doesn't call it a Glock, it calls it an "Automatic Pistol", which is exactly what it is, just like the rocket patent calls it a "High velocity impulse rocket". As for the warheads, "The payload may be any one of a variety of payloads, such as a kinetic energy penetrator, an explosive warhead, an electronics package, a debilitating gas warhead or a chemical/bacteriological warhead, or in some applications, no warhead at all." Another example of your word twisting; "You do believe artilleries have a initial When you've finished grade school and finally gotten into high school, you may learn that velocity and g-forces are not the same thing. Why would somone want a rocket instead of a cannon? When's the last time you carried a cannon on your back? DUUUHHHH(slack jaw with drool). You have this habit of throwing out red herrings to try and distract from your lack of facts. Very annoying. Like a mosquito buzzing about. Finally, "patend (your spelling)" is correctly spelt as "patent". Please make a note of that. ------------------ |

Nothing else to say besides bad spelling? NBK? When you finished basic science courses like kinetic physics(well you have to stop being cranky in class to learn faster), you'll know that the accleration is directly related to force, the burst of acceleration will detonate explosives, and any other warheads are not practical for this shell due to the short range and lack of maneuverability.(Just list the detonation threshold to show you, your previous post just told, you don't have any glue, clue, sorry for the spelling.) For the old .22 thing, NBK, I know guns more than you do, which you should already admit. You are the one who dances around to avoid facts that are not on the pro side of things you mentioned. If I am an annoying mosquito, Don't feel bad, it's not your patenf after all. Don't distract yourself, O twisted one. [This message has been edited by HMTD Factory (edited March 08, 2000).] |

Since your unable to refute anything I've said with facts you've had to resort to word games. There are so many red herrings in your last post that this topic smells like a fishing boat. "You are twisted now NBK". Wrong. I've always been twisted, but not when it comes to facts. "...a rocket like ...., recoil backward,..." Did someone forget the 3rd law, you know "equal but opposite"? Rockets don't have recoil. If you can't get even that simple fact straight, what hope is there for the rest of your "facts"? "...this shell due to the short range and lack of maneuverability." Again, read the patent. It's not intended as a guided missle. The rocket travels so fast that wind doesn't have time to affect the flight to any significant degree. As for accuracy, that's a matter of tolerances and reproducability of design. And short range? Did you miss the mention of orbital insertion? Obviously someone hasn't bothered to read the patent before spouting off at the mouth. And in yet another example of word twisting you say that "..you'll know that the accleration is directly related to force..". I said "..velocity and g-forces are not the same thing.". Please learn the simple fact that Velocity and Acceleration are two different things. Both of our statements are correct, but your infering that mine is wrong just because it's different. Look up the definitions (although I already know you won't) of "Velocity", "Acceleration", and "G-force". ------------------ |

Well alright Ho ju, I can yield. The shell can be produced without Hi-Tech machine/material. Cryo'ed steel can be used as shell hulls due to enhenced strength. No explosive initiated warheads are to be carried by this shell. The sudden force provided such acceleration will cause detonation. Winds affect objects traveling at high speed especially. The recoil IS opposite to the direction of traveling and gas jet from the shell can knock down the launching person at the rear of its nozzle.(if the 3rd law is EQUAL and OPPOSITE, then the recoil are suppose to be Will select and delete posts. |

I've already disproved everything you've posted twice already so I don't need to go over it again. ------------------ |

Well i guess this Thread is going no where fast. you both presented good arguments in your own right and i think you people have said all you needed to say about this subject under this thread. ------------------ http://members.xoom.com/Splynncryth |
