  1. Banned for not realizing that on this page 1296 96/12=integer 8.
  2. and has radiator panels which radiate heat in space, and uses LNa as a coolant to transfer the heat from the reactor to the panels. The reactor itself is too small and dense to be an effective radiator.
  3. Voskhod has been cancelled for the sake of more robust Soyuz, which was able to maneuver, let the crew get in/out, carry a pack of missiles (7K-PPK) or a autocannon (7K-VI and probably 7K-P). The militaries were agreed for a while to keep having Voskhod in hands rather than Soyuz in clouds, but Korolyov was among the main Soyuz proponents, as it was following his idee fixe of the Martian (after the Lunar) expedition, and was compatible with his lunar plans. So, two more planted flags would play no role. Also, the next Voskhod was to carry Yuri Senkevich, the cult figure of the Soviet paraspace and paraesoteric propaganda, the Soviet TV narrator, the official top of the medical part of Korolyov's space program, who would undertake a surgery over a rabbit in zero-g. As we know now, only Yulia Peresild (I would give her two Hero Stars, for the flight, and for the b...hurt canonade which it caused) can do surgery in zero-g without the patient's bleeding. So, it would be a doubtful flag next to those ones, like the Laika death was. (Though, I would add "The Herbs and Stewed Rabbit" orbital experiment, to make happy at least the tolkienists.) A kind of oxymoron. It would fly due to better quality control in Kuznetsov bureau, having upgraded the pathetic NK-15 to the excellent NK-33, so that even Chelomei was going. to use NK-33/NK-43 in his UR-500MK kerolox Proton. Nobody but specially dedicated people in the USSR was aware of the Space Race is even happening, N-1 ever existed, and Soyuz had any relation to the Moon. The official story was that after the Luna-16 and -17 have delivered some ground and had riding across the Moon, the race is over, and "who needs it anymore?" This flying snowman was another dead end of the Soviet rocketry, like R-7, having lousy 95 t (modified) payload. Too much for daily needs, pathetically low for lunar trips (needing at least ~150 t). Both Korolyov's N-1 and R-7 were totally unupgradable due to their conical shape, handworked curvatures, lack of waffling of the internal surfaces due to the shape, weak (RD-107) or unstable (RD-111) engines. That's why immediately after the N-1 had been finally cancelled, Glushko and Yangel immediately had to start a new rocket family (Energy/Zenith) from scratch, and were still limited with the factory equipment left from the N-1. A successful flight of N-1 would be slowing any further development of alternatives at all and the orbital stations in particular. N-1 was able to deliver one, and had no reserves for upgrade. It's like all Korolyov's designs, brilliant for a barn rocketry of the GIRD times, but weird for mass engineering.
  4. Mount Duke Nukem. Because 3- d > 2+ d.
  5. Floor 4630: A dystrobar. Zero calories in every bar meal.
  6. We call it Neptune soup, as there are several sorts of hot ice in the Neptune. Waiter! Just Cola with ice. With heavy ice. With heavy water ice.
  7. Calling 911 because you aren't you.
  8. Who called Mizery? She's going to ban him. The thagomizer is a result of a reconstruction mistake. Actually it was directed downside, and the steganographicsaurs were using it as a plough to farm crops. (Or the Elder Ones were doing it with the stegosauruses, by rotating their tails upside down.) Btw, an idea for the Atlantis fans.
  9. And that's the problem, as the high thrust means high energy production rate, and most part of this energy will be waste heat, heating the solid structure of the combustion chamber, regardless of physical principles of the energy production. This means either appropriate size (tens meters) but low thrust, or high thrust but huge size (kilometers), as L ~ R2T4, so RT2=const. As the T is limited with the construction (i.e. solid) material melting point, so R~sqrt(L), i.e. chamber size ~ sqrt(energy production rate, and thus thrust). It's possible to actively cool the chamber, but as it happens in vacuum, the only way is to radiate the waste heat outside with radiator panels. But first, the panels temperature is limited with melting point of the panel material, and boiling point of a droplet-based liquid cooling, i.e. in a ny case with 1.5 .. 2 kK. And second, you should transfer the waste heat from the chamber to the radiator, so you need a coolant and pipes for it. So, this is also limited with melting point of pipes, boiling point of liquid cooland or ionization point of gaseous one. In any case, the active cooling system temperature is limited with ~2 kK, and this makes the low-thrust-vs-huge-heavy-chamber inevitable. The only realistic, not handwaving, way to solve it, is to completely remove both combustion chamber and cooling system, by moving the reaction zone far outside from the ship, and directing the kinetic energy from the reaction zone towards the ship rear shield, aka pusher plate. And that's what Orion is. The propulsion nukes don't have to be full-featured weapons. They can be simplified, purposed only to interact with the ship drive. Thus, they can widely use U-233 deuteride instead of plutonium, and be compressed by the Z-pinchers, like in minimag Orion. The same can be replaced with fusionukes in the more future future.
  10. Just a moment, sir. I'll catch something and substistewte it there. Bartender! Stop lighting the alcohol shots. Every burning shot is warming the atmosphere and fills it with carbon oxides.
  11. Equestria is the vegans' hell. Only grass to eat, and the pony rides you.
  12. Floor 4628: The dystarting past of that future.
  13. Lemmings The people who ask "Lemme in!", being not aware, what's in.
  14. 1. Orion receives just the part of total heat which is carried by the plasma jet. Most part of waste heat dissipates around the explosion point. 2. Orion works in pulse mode, unlike the continuous chemical or nuclear reaction engines, so it has ~0.5 s to emit some part of the absorbed heat. 3. Orion pusher plate is cooled by portions of coolant water, pumped through the plate internal structure/ 3b. The Orion coolant water doesn't need a close cycle, it turns into steam and gets vented out right in situ. Loss of water? No, a free attitude control, water-steam RCS, to hold the Orion on course during the engine work. 4. The Orion pusher plate is massive, unlike the nozzle lattice of permanukes and thin chalice of chemicals. It has great heat capcity, so the waste heat is distributed uniformly. 5. The pusher plate is prevented from the direct tungsten plasma hit by the soft plasma cloud of former oil, sprinkled on the plate between the explosions. 6. The Orion thrust is great, unlike the puny permanuke nudging. The interplanetary jump acceleration takes less than hour. So, the Orion doesn't need heavy rad protection from permanently working megareactor, the crew can sit in a small room, protected from rear end. Thus, it's more safe and efficient even from the radprotection and mass view. And this is a description of the coolant water and sprinkled oil. From the very beginning the Orion was to use several yield in flight, from sub-kiloton in upper air (and, I guess, in the Martian de-orbiting), to several kiloton in vacuum, exploded at different distances. By varying the yield and the frequency, it can vary its thrust. It can go down instead. The onboard reactor for the minimag Z-pincher can be using aneutronic B+H or N+H or C+H fusion, where the non-charged particles are generated at low rate, or even (B+H) be absent. Though, I believe that the mini-mag is a temporary-to-never intermediate design, and the two-staged fusion X-ray laser charges, compressed to fusion by similar Z-pinchers (i.e. returning to the original idea with intermediate inert discs) can bring the thrust to interstellar ark values.
  15. /Oh, /you/ /see/ /age/. Spelling ban.
  16. If compare the pusher plate and nukes total mass to the enormous kilometers-wide structures or negligible thrust of its alternatives, then Orion is super-efficient. It combines small size, low mass, and short burn time.
