The amount of heat generated by a system is constant, it doesn't change with dissipation method.
Still the amount of IR given off could be felt differently.
Well, now plane is part of the system, it's no longer matter of stand-alone specs but how well it works as part of, say, air-air defense complex as whole - supply, maintance, coordination etc.
Millitary hardware gets more boring lately
Yes, realistically the US has the biggest integrated military, although, far from perfect.
The israelis are probably the only one that's on par. But given time China may become more of a threat than russia. Anyway, the article will force that war strategy will move into space or shipborn weapons. Emphasis will be set on long range bombardment.
Well, I think cost is the problem as to why there is not much new coming. All the new fancy tech is just too expansive.
Oxygen fuel cell It seem the 'blog' is BS. 1000 degrees is below fire temperature which is a given for catalytic processes. In the past fuel cell had 400 degrees or more so this one may be unrefined, but higher temps also means more efficiency in terms of thermodynamics.
On the other side
this(2007) is said to be fundamentally new and better. Now available in
battery size.
The japanese decision to move away from hydrogen fuel for now is smart and considerate.
The problem lies in storage tech still loosing too much fuel over time, hence, worsen global warming. Of course this doesn't mean hydrogen tech will die, just delayed. After all the cycle of hydrogen and electricity is most desireable.
Someone wants designing machspeed aircrafts again.
Pic1 Pic2 Pic3 Pic4Well, looks nice but totally off: barely not enough fuel for any length; center of gravity will be hell of a problem.
I think speed is prohibitive in the future as it always wastes exponentially more energy.
Efficiency must be very high to justify.
Edit:
Atlantic plastic patch determined!
