They're sort of in a different weight category. Pacific Rim has absurd violations of physics to make the Jeagers work as a humanoid weapons system. In comparison, an Object is to physics as a D&D Sphere of Annihilation is to everything; When moving at 500 kph (not quite top speed), they would be losing enough energy to air resistance to melt about twenty tons of steel per second, and heating their (steel) hull armor to a similar degree.

The point Heir of the Void is making is that the laser propulsion system is not 100% efficient (no machine is). Some energy used to move the Object will be released as waste heat. Since the Object is huge, it creates a lot of drag compared to say a jet, thus more energy needed to maintain top speed. As a result, The heat produced will melt the Object.
Let's just say that laser tech has advanced such that its close to 100% efficient and the material used has a ridiculous high melting point and a ridiculously good heat sink is developed and call it a day. The bottom of the Objects do get melted though and is replaced periodically. (the water strider needs to replace the legs twice per day) Let's just treat the top speed as just that: top speed and not a speed that the Object can maintain for long.

Comparatively, if an Object is abstracted into just the spherical main body, its drag coefficient would be at least .5, give or take. That's what I used to calculate 5 GW of drag. In actuality, the drag coefficient would be much higher, the various weapons protrusions would make the flow lines resemble a plate of spaghetti, and probably have a lot of other bizarre (and negative) effects on airflow. Also, an Object is traveling at or around sea level, whereas supersonic aircraft are generally more than ten thousand meters up; the much lower air density at that altitude is good for cutting down drag. |

Actually, that Laser Launch Technology, and its a real thing. Most of the feasible designs work by using a laser on the ground to blast a target of ablative material (ceramic, probably) into plasma, which then explosively expands to propel the vehicle. There are a few designs that don't involve starting with a solid-state fuel target, but they generally use something to capture the heat of the laser to expand working gas contained in the craft.

Certainly, you could force it to work, but the end product would be horrifically inefficient AND result in either 1: A continuous firestorm and Hiroshima-grade thermal flash around the object or 2: A somewhat less impressive firestorm, and an object that posed a severe radiation hazard to every living thing (and sensitive electronic device) above the horizon. My design would basically be a Plasma Jet Engine. Air is drawn in from filtered intakes (at speed you could use the forward motion of the object to smash the air through a nano-scale particle filter, if you feel that would be beneficial) and pumped to a reaction chamber where a carefully controlled amount of plasma is injected. The plasma super heats the air, expanding it and then uses that expansion for thrust. The drawback of this scene is that it would require an 'engine' with a defined 'front' and 'back', and a single vector of thrust. Though with a centralized pump system and multiple apertures... Primary weapon would be a free-electron laser optimized for the middle-UV range, intended to target and destroy enemy orbital assets, which would shift to an x-ray spectrum beam (Because you can do that with a FEL) to engage Objects. The other primaries and secondary would all be intended for maximum trolling; neutron beams to transmute the enemy's armor into radioactive isotopes, railguns with slugs desigined to crush a small sphere of plutonium to super-critical mass with their impact force, stelth drones to draw on the faces of the enemy's support crew, that sort of thing. |

its Ghost Madoka time!!!

i was expecting Qwenthur to be a jackass when trying to render all the spare turbine useless by poking each every of them as fast as possible if it weren't for a conveniently placed maintenance log just left there in the room by a dumbass staff member

Reposting again since I was able to get this image up and running, but realized that it was far away for peeps to see it:
For these 8x8 IFVs, I first thought that they could be BTR-80s/90s. I realized that the front hatches were different, but the designs do resemble those made in Western countries. Then again, this may be just a fictional APC made for the show. Perhaps the same for the autocannon/HMG setup.

Complicated and implausible propulsion systems aside, don't you think the self-destruct mechanism needs to be redesigned? Or maybe scrapped entirely? They lost their billion-dollar (or maybe more) equipment due to a wrongly designed self-destruct system. It should prompt upgrades in that area.
Today's weapons have self-destruct systems that destroy the data stored inside of themselves- that's it. Warships, our most expensive weapons, don't even have those because mother nature will destroy the data for us if the ship is ever destroyed. It also to me seems implausible that objects could be piloted by just one person. For a warship, which has like 3-4 different kinds of weapons onboard (same as object), it takes a team of 6 people to operate the weapons and sensors, and another team of 3 people to move the ship around. For a fighter plane, it takes only one person. Not sure why that is. I guess if there's only one enemy unit and your one unit is invulnerable to most things, things get a lot simpler. Pilot-chan is a little too young to be piloting. I think you can pilot if you're 18 in today's US military; it's probably the same in Japan; she is not even that old yet. It also takes ~18 months of training (US military) to become a pilot. |

Think of each of them as a Gundam rather than the mass produced mobile suit. As for the pilots, we'll leave that for a later time.

Axs for the point about crew: yes, this. Even if the pilots were psionic extraterrestrials, they do not use a direct mind-machine interface, so even if the pilot had the raw processing power AND the multitasking ability to preform all of the necessary tasks (and the two are very different capabilities), the control would still be a severe bottleneck. I think the only way this setup could work is if the Object is essentially an autonomous robot with the Elite Pilot being an overseer and strategist who happens to be inside the robot, giving it commands to execute rather than using it as an extension of himself. Otherwise, they'd probably need to go as far as using the pilot's nostrils as command interfaces to get enough bandwidth. As for how fighters can have a single pilot, classically it's because fighter weapons are almost universally on a forward-fixed mount, so flying the plane is aiming the weapons, and later because getting a missile lock was about getting the enemy in your (forward facing) missile lock zone long enough for your computer to lock on to them. Interestingly, in a lot of ways, a modern (Fifth-Gen) fighter is almost an autonomous robot with the pilot being an overseer and strategist who happens to be inside the robot, giving it commands to execute rather than using it as an extension of himself. For example, most modern fighter aircraft are intentionally unstable, then stabilized by precision computer control to allow extreme agility in combat. This has the downside of making them practically impossible to fly without the computer. Admitadly, I think I could by the Objects easier if they had even one to two dozen crew; at that point, I could think of them as warships rather than funny-looking Gundams. And that's not even getting into the psychological effects of giving that power to one person. If you weren't a psychopath before you started piloting... And as for the age... they have an 18-year-old with the rank of Major in command of a Weapon of Mass Destruction. By U.S. Army standards, the sum of the time-in-grade requirements to reach Major is 8 years, and it usually takes considerably longer than that. Quote:
But seriously, the self-destruct command system is shit. It should be manual-only as long as the pilot is alive and capable of commanding the craft; the automatic detonation should be active only if the pilot is dead, the pilot has ejected, or the pilot is alive and the ejection system is non-functional. |
