1000C to -150C in 1/100th of a second

[vitchilo]

This is the technology invented by a British company for a space plane... now just imagine if applied to computers??

British company claims biggest engine advance since the jet

The space plane, dubbed Skylon, only exists on paper. What the company has right now is a remarkable heat exchanger that is able to cool air sucked into the engine at high speed from 1,000 degrees Celsius to minus 150 degrees in one hundredth of a second.

Please please please??? CPUs to 1 terahertz, yes we can!

[kromosto]

that cpu will not understand what happened to her.

[Evantaur]

so the cpu goes from +30 to -150c and says *crack*

I can't think of many materials that will take to that fast of a temperature change too kindly.

Did they get permission from Napier to use the Sabre engine name, or was it never protected?

It's crazy to think that jet engines have "limited" us to M2-2.5 since the E.E. Lightning hit mach 2 in the 1960s......and that appeared to be limited by the structural integrity of the rest of the plane!

The SR-71 could cruise at M3.2 and it was turbojet powered, although the afterburner behaved more like a ramjet at high mach speeds.

this technology isn't just to cool down air ? anything solid will mostly results in crack.

I did some programe work for the early engine design on a Cray XMP48 on the design of the air intake as a research student. I use to turn a lot of data in coloured pictures of the air intake using 3 D modeling. The bigest problem was the amount of O2 in the air past 100,000 feet to burn with the fuel, the question was when would the plane have to use the internal oxygen.

The headline is a load of Bull, the temperature of the air is due to the speed of the plane and the high temperature is caused by friction of the atoms agaist the metal surfaces of the plane. In this case the air at Mach5 hitting the blades of the turbine generates the 1000C.

The simple solution is to take the air into a camber and allow it to expande to use a simple law of science. A compressed gass allowed out to expand will decrease in temperature "Gas Law". Concord also had the same problem and the same solution, the air intakes gave way to a large expansion chamber that cooled and slowed down the air to allow the engines to work.

In my day it was called HOTOL.

This is just a Headline to attract 250,000,000 pounds to build the prototype plane!

What altitude for M3.2?

[Kallenator]

What altitude for M3.2?

From Wiki.

Performance
Maximum speed: Mach 3.3[83][84][N 5] (2,200+ mph, 3,530+ km/h, 1,900+ knots) at 80,000 ft (24,000 m)

To my knowledge, fast-moving vehicles in the atmosphere are heated almost exclusively by the compression of the air through which they move, not friction as commonly believed.

Friction!

Ah. I was thinking Topospheric, not Mesospheric (or overall)

Or maybe i'm just wrong
