@dsdy12053 жыл бұрын
6:20 In the original Valkyrie design this was done with a very large droplet radiator, but it's not as visually impressive as a solid panel radiator 6:25 the original Valkyrie design also made use of only one engine, with a combined defocusing / shadow-shield system (which also includes the matter fuel) to shield everything downstream of the engine from the emissions of the engine, which are mainly concentrated around the reaction zone of the engine. 6:34 In the Valkyrie design this was not needed since the ship ran on pure antimatter. The antimatter was created by literally strip mining Mercury with self replicators to create enough solar collectors and antimatter plants. In the case of the movie, yeah it's a ridiculously powerful laser, but one would argue you'd need as much to do any interstellar travel. The engines on the Venture Star put out very similar levels of power. 6:49 Because the laser emitters are on Earth, and can only point towards Pandora. You can't pull the ship back from Pandora to Earth with a laser sail system unless you use disposable sails to bounce the light backwards.

The radiators are probably only used during downtime between firings of the drives, drawing off the heat of a small onboard reactor that manages things like life support, lighting, recycling, etc. When the drives are in operation, waste heat can be extracted by the reaction mass you're dumping into the drive plume, by becoming part of the thrust plume that excess mass is itself stealing energy (heat) from the drive, which will lose some of it's Isp in exchange for increased thrust. Granted this still wouldn't get rid of ALL the waste heat from the drives, but if the drives are bimodal and can run as fusion plants with much less power generation you will need at least significantly smaller radiators, though not no radiators at all.
@nocare3 жыл бұрын
The problem with the ISV engines is the extreme amount of energy required to maintain the level of acceleration cited for the design. It takes something lake 800-1600 megatons of TNT worth of energy every second for over half a year to work. Although antimatter has this level of energy density even a 99.9999% efficient engine would produce so much waste heat as to vaporize the radiators almost immediately. There is no getting around the need for massive radiators to cool the engines even with magicly capable unobtanium. As there isnt a remotely realistic way to get the efficiency high enough that radiators are unnecessary. They are also massive heatsinks not just pure radiators. Thus why they are so thick instead of more efficient thin designs. Even chemical rockets still need radiative cooling, they happen to get away with using only the engine bell as a radiator. Last even a multi-gigawatt nuclear reactor with a efficiencies of 30% could get away with radiators that are 1/100th the size of the ISVs. The higher your efficiency the smaller your radiator and with Avatars magic tech they should be able to cool reactors with radiators the size of a car.

The expanse has pretty realistic designs for spaceships. The only technology they have is the Epstein drive, an extremely efficient engine capable of producing thrust for weeks at a time. No artificial gravity generators or anything like that. Gravity comes from ships accelerating continuously (with rocket boosters on the bottom and the decks layered like in an office tower). Also spinning components for locations where continuous thrust isn't practical such as space stations. Communications between planets takes hours or even days depending on the distance between the communicators. Space battles take place over hundreds of thousands of kilometers, with the biggest ships carrying missiles that can take hours to reach their targets.

I have thought, ever since I saw it, that an adapted version of this could be built as a "train" between Earth and other planets in the solar system. Strap a couple of VASIMIR drives to it, put shields at the front too, and use compact nuclear reactors such as the Soviet TOPAZ design to feed the drives and overall ship systems. Have a larger set of radiators, and deployable solar panels for when approaching the inner solar system, and you have a very capable ship, able to transport huge loads at very high speeds. Build a bunch of them and have them continuously travelling back and forth from other planets, like a terrestrial train. One in orbit at Earth, one in transit to the planet, one already coming back, one in orbit at the other planet, and one in maintenance at orbit. We would have to build one or two space stations way larger and more complex than the ones we have today to build and service them, of course, and maybe build them orbiting other planets, like Venus and a Jupiter, in order to have resources for emergencies, and safer procedures and communications. Starship's cargo capacity may allow for all of this, like other vehicles like the SLS or the Vulcan(when they become available)...

Unfortunately we don't have engines that are anywhere near efficient enough. Looking at the size of the fuel tanks on this ship we could probably pull a 1.5g burn for a handful of minutes with modern technology. The ISV Venture star is capable of doing that for 170 days each way (meaning if they can't produce the anti-matter fuel at Pandora it would need to be able to perform that burn for 340 days). Increasing a ship's Delta-V to the levels needed for interstellar travel is probably the biggest challenge with creating a vessel like this, and engines of this class are are vaguely theoretical at best for modern science.

The design of this ship is PERFECT. But I have one note. Why not to turn the antimatter engines nozzles back away from the crew modules? The plasma and radiation will be directed behind the ship, far away from the crew modules. Even though they have some radiation shielding, they would not save the people inside because of the MASSIVE amount of radiation caused by the engines. Also the crew would be literally cooked inside of them due to extreme heat of plasma plumes

Wasn't the ship pointed in the wrong direction as it approached Pandora in the opening sequence of the movie? And also it shows the mirror facing the engines which I never understood. Shouldn't the mirror have been facing the opposite way to shield from the laser? Maybe it was mirrored on both sides and we just never saw the other side of it. But not sure why the surface facing the engines needed to be mirrored. Also it seems the ship was sort of a sitting duck if there were any objects in the path that the shields could not protect from. I'm not sure if it had any maneuvering capability once at speed. Any slight evasive action by a thruster to avoid impact with a large meteor could alter their trajectory with Pandora and cause them to miss the target and the ship would be lost and all crew and passengers would have to be euthanized. Sounds like a nerve wracking 5 year journey!
@hoojiwana3 жыл бұрын
It doesn't use the main engines when right near a planet, something I didn't mention! And yes the shield appears to be double sided. As for larger objects, theres essentially no chance of meeting something big being out between stars. Even if there was, they have the smaller manuvering engine to do slight course corrections to avoid things (if spotted long enough in advance).
@StacheMan263 жыл бұрын
A "little" late to this, but presumably the mirror shield is double sided so that they have a backup on hand if the aft facing surface becomes too damaged by interstellar debris to protect the ship from the deceleration lasers on Earth return. Seeing as not having a backup would lead to either large portions of the ship becoming molten debris and/or it hurtling right out the other side of the Solar system with no hope of recovery, having a backup mirror is kind of important.
@marianpazdzioch66323 жыл бұрын
Wouldn't it be more efficient to retract mirror instead of wasing % of the thrust because of that additional angle ?
@kerbodynamicx4723 жыл бұрын
This mirror shield isn't like the thin film of reflective material that makes the laser sail, it also acts like multi-layered armour that stops incoming debris, so is presumable very heavy. Moving it will require a lot of large electric motors, which will add extra mass.

One reason I can think of for not using the the laser on Pandora too would be that if the ship was designed that way they would need a laser to already be on Pandora in order to slow down. So they would need a ship like this one to be able to get there the first time and to get there and back however many times it would take to bring all the equipment necessary just to build the laser on pandora. Then they would have to build a whole new ship designed to use the the lasers both ways as to not have to carry the engines this one has around as dead weight which would waste cargo space. So it would probably be more cost effective to just keep using this system instead of having to build and transport all the other infrastructure needed for a laser to be used both ways after which this ship would become useless.
@lmlmd2714 Жыл бұрын
Absolutely this - not mention the infrastructure to power the thing. It's clear that the operation on Pandora (in the first movie) was a bare bones strip mining operation to get what you need and nothing more. Anything not directly related to that end was a waste of money. Harvesting fuel for the engines would be the absolute maximum trouble they'd be prepared to go to. It'll be interesting how it develops in the future films as it's clear the humans now see Pandora as a target for settler colonialism, not just a source of resources to be exploited.
