The PlayStation 3 Thread!

5k each? Wasn't it going to be a 80/20 split, production-wise? -
Transformers Super Thread 4: The Return
David Hingtgen replied to Dangard Ace's topic in Hall Of The Super Topics
True, going for "realistic" white and black shuttle mode is kinda pointless, when you have bright purple train-halves on the wings. -
Quick comment: "AV-8" is one of the "wrong" designations in the US military that really doesn't fit/conform. It's out of sequence and the letters are backwards, or both. It's often said it might actually be a joke---A V 8. Aviate.

Transformers Super Thread 4: The Return
David Hingtgen replied to Dangard Ace's topic in Hall Of The Super Topics
Or the simple reason behind the original color scheme: Astrotrain was white and black. Space shuttles are white and black. Steam locomotives are black (often with white trim) He was realistically colored in both modes, which is pretty rare for any non-car TF. I always wanted a white Astrotrain, as it'd make for a "perfect" shuttle mode. Didn't Diaclone Blitzwing have grey and green for the same reasons? -
The heat the engine makes has little direct influence on thrust. The most powerful jet engine ever built is among the coldest-running ever built. Heat=noise and fuel consumption, mainly. The goal is to make thrust, not heat the atmosphere. Heat coming out of the engine is basically "wasted fuel energy"---it would have been better for that heat to be converted to kinetic energy to increase the velocity of the exhaust. Jet engines have always preferred dense air, it directly influences thrust produced. Every jet in the world has a "engine performance based on density of the outside air" chart. Density of air is affected by temperature. Cold air=denser. Airliners were the main users of water injection, but no longer. If it was really cold out (below freezing or so) you could operate the engine at "water injected thrust levels" without actually using the water--because the air was so cold and dense anyways, water injection would be pointless (and it might freeze). Anyways, the water is injected in the compressor section, not the combustion section. The point is to increase the density of the airflow. Thrust is change of momentum, momentum=mass x velocity. (that is how a jet engine works, nothing more--mass and velocity of the air---not its temperature) Anyways, say you inject water into the airflow going into an engine. As the air is compressed, it heats up. It'll heat up enough to vaporize the water. The water didn't heat up by itself, the heat was transferred to the water from the air. So the air is cooled. Ideal gas law (chem 101): p=p/Rt or Density=pressure/(R*temp) If temp goes down, density goes up. Increased density means more mass per unit time. Since thrust only cares about mass and velocity, more mass at the same speed means more thrust. The short version has always been "the water fools the engine into thinking its sucking in more air than it really is". Cooling effects and reasons (and how the Harrier uses it and why) are another topic, I'll post that tomorrow. (Nitty-gritty jet physics are always taxing---I have to get my books out to get the formulas right, etc) PS--water injection often leads to black exhaust, a big reason it's no longer used. Not simply "smokey" like many old jets are, but BLACK, like this: http://www.airliners.net/open.file/0541868/M/

It has everything to do with weight. There is no "V/STOL system", it's simply water injection. Old and simple way to temporarily increase the thrust of jet engines. You get increased thrust for as long as you have water to inject. There's a zillion Harrier variants out there, and an equal number of engine variants, but here's an example: Harrier weighs 20,000lbs. Engine normally can put out 19,500lbs of thrust---not enough to takeoff or hover. But with water injection, thrust can be boosted to 20,700lbs. That's enough to take takeoff. But it only carries enough water to do that for 60 secs. But if the Harrier only weighed 18,000lbs, then the engine at 19,500lbs of thrust could easily lift it, without resorting to water injection--and it could keep it up for quite a while. 19,500lbs would probably be the 5 min takeoff limit, but if the Harrier was that light, you could probably have the engine set at max continuous thrust--which is exactly that, and the Harrier could hover indefinitely. Harriers use water injection for both power and cooling---but the more you overstress the engine, the more it's relied on for cooling. But it still comes down to weight--if the plane weight less, the increased thrust wouldn't be needed, and the engine wouldn't have to work as hard, and it'd have no cooling issues at all. Every little bit weight at the upper end makes the engine work a LOT harder to get that extra thrust to carry the weight. Weight=more power and fuel needed. (even in level flight) More power=more heat. Cooling issues are the result, not the cause.

Which technically isn't flying... (The wings make NO lift in battroid mode, extended or not---they're only spread out in battroid mode so the missiles have room) With the power valks have, there really shouldn't be any time limitation for hovering. If the Harrier could shed 2,000lbs it could hover for as long as it had the fuel to do so. GERWALK mode is far more interesting, for the feet are delivering vertical thrust, and all forward thrust is from the backpack, thus the wings also develop lift so long as you're moving forward. (so you should actually have the most lift in that mode) And as we see in M0, aerodynamic controls certainly play a big part.

I'm shutting down the decal and sticker business
David Hingtgen replied to Anasazi37's topic in Toys
Plus Hasegawa decals are the thickest in the industry. You want thin decals? Microscale. Nobody makes them thinner, nor can print finer. Cartograph is next. And there's a number of very good printers in Mexico and South America, which are often strangely 'anonymous'. Of course, thinness and conformity are quite separate. Hasegawa are thick but conform well, while Academy are thin but stiff as cardboard. -
Gunpod for VF-11B (from Mac+) pics?
David Hingtgen replied to grebo guru's topic in Movies and TV Series
The VF-11B's gunpod is quite different from a C's (it's not just a C's with a bayonet), and with the B's gunpod being fairly heavily featured in Ep 1 of the OVA, there should certainly be some official artwork SOMEWHERE of it. I mean, there's multiple views of the door hinges for the connectors for the sound booster of Mylene's valk. Surely the VF-11B's gunpod deserves lineart. -
Is there a good place to get replacement decals
David Hingtgen replied to PDeMaio's topic in The Workshop!
We're ALL going to need YF-19 decals fairly soon, sure hope Takatoys or someone can deliver. -
Kikaioh rocked. The more anime series you've seen, the more you'll get out of it. Still amazed it came to the US. Reason enough alone to never sell my Dreamcast. (though the final boss is CHEAP imho)

The mini-game for a PS3 wait should be Tekken 1. -
The PlayStation 3 Thread!
David Hingtgen replied to Apollo Leader's topic in Hall Of The Super Topics
The more translations of Famitsu reviews I see, the less credit I give the magazine. Nobody is more shallow/cares only about graphics than Famitsu. GamePro is better, and I realized GamePro really sucked when I was 11. -
I'd argue more for "stylistic" drawing than lazy. Alternate universe Burkes or something.
-
Northrop jets have always been sleek as hell. The F-5 prototype could supercruise, the YF-17 could (yup, it's THAT much sleeker than a Hornet), and we all know about the YF-23. IIRC, the YF-22 design couldn't supercruise until they brought NASA on board to "tweak" about a zillion points on the airframe until it could slip through the mach. Whereas the YF-23 in mil power will easily out-accelerate a F-16 in burner.
-
Yup--clearly Burke-ish, but not a Burke. Nor the JASDF Kongo class (their version of the Burke). They're just far too "swept back" overall.
-
What's with all the people selling their PS2's? Yeesh, I still have my PSX. (you never know when a backwards incompatability may crop up--and the amazing fact that sometimes the fast-loading is actually slower)
-
Plus the little fact that MiG-29's that do have louvers have them closed most of the time, and they're very hard to see when they're closed. Why model opening louvers when you can just show them closed?
-
The F-22ish F-15 design is only a silhouette, but trust me, it's 99% accurate to an YF-22. It was one of those "history of the design charts", and there were basically two final choices after all the refinements: What we got, and one that looks like the NEXT fighter we got.

Huge FF fan (I like JRPG's, should be obvious by now), but I skipped 11. Saw 12 tonight when I was preordering CV: Portrait of Ruin. Will probably pick it up sometime in next 2 weeks. (Still have to finish Okami, which went on hold for Valk Profile 2).

Telekinesis=Jean Grey=able to do ANYTHING with enough practice/skill.

I'll let Nied handle this one. Accurate and correct Flanker info: http://mysite.wanadoo-members.co.uk/flanke...anker_home.html PS--wasn't the Su-37 officially called an Su-35-2 or something? I know Nato designated it a "Modified Flanker E" (with the Su-37/27M being the standard Flanker E) Note the use of past tense.

Transformers Super Thread 4: The Return
David Hingtgen replied to Dangard Ace's topic in Hall Of The Super Topics
Um, "Hulk" was the movie debut of the F-22. They said Lockheed themselves provided pics/specs etc for it to be accurately modeled in CG. Maybe it's the debut of ACTUAL F-22's on screen? Though I don't recall any mentionings of F-22's being flown for filming. -
Ever see the 2nd-to-last F-15 design proposal? Matches the F-22 almost exactly. The YF-22 looked more next-gen than the F-22. They "F-15'd it up" for the production version.

Transformers Super Thread 4: The Return
David Hingtgen replied to Dangard Ace's topic in Hall Of The Super Topics
Or even better, start the rumored "military" line of Alternators. F-22 Starscream... Though we still don't know if SS is a YF-22 or F-22. The early design art was clearly a YF-22---you know, the cyber-monkey that they said wasn't anything like the final version. Sorry, never really like Megatron's design. Character yes, robot no. I only complain about stuff I care about. (note I haven't said a word about Classics Bumblebee for example--I simply don't care about him)
