Woot! the mad boffins of jet reaction are testing the engine for Skylon the son of hotol yay.
Proper bleeding edge tech that could cange the world.
had a spot on the news

This sounds like the best investment opportunity in decades. If there was a share option in REL I'd stump up a few bob, jut to keep the development in UK.

Alan Bond isnt a fake. If he can make this work, then the jet engine is sooooo last century.

Its great getting up there, and the orbital mechanics are elementary my dear (Gene) Krantz, but re entry may be problematic. Most delivery systems dont even concern themselves with re-entry at all and leave that bit out of the engineering. I'd be interested to see if Skylon or anyone else, could explain how the heat of re-entry is going to be so simple. Does the re-entry just tear the engines apart? does the outer skin of Skylon need replacing after every flight?

Saw the same clip on the box. Looks excellent so it'll go the same way as all of our other inventions:
Yeah. Jammed into a plastic tube for 12 hours eating shite food and watching a bollocks movie over headphones that crackle then having some fat bint with hormone issues telling you that you cannot have another plastic little bottle of wine on your shitty fold down laptop 'table' then somebodies ******* sprog pukes on the back of your seat and starts to howl and the fat **** next to you quietly voids his bowels.

Hell in space vs Hell at 50,000ft? Hmmm. Tough one.

Any help?

Reaction Engines Ltd : Current Projects : SKYLON - The Vehicle

During re-entry, which occurs at an altitude between 90 to 60km the heat is radiated away from the hot aeroshell. Heat is prevented from entering the vehicle by layers of reflecting foil and the low conductivity shell support posts. Liquid hydrogen is evaporated in the main tanks, passed through thermal screens to intercept the small residual heat leak and then vented overboard.

We have been promised this stuff and spandex jackets for fifty years, Please lets get this one off the ground.It would be nice to have a future for uk plc.

What you need is a hook on the bottom of the space station and a long rope that you could lower skylon down on. Nothing is hard when you think it out properly.

TY scalieback.

I'm just a little doubtful about the "reflecting foil" as I dont think such a thing exists: its usually huge chunks of ablating ceramics.
I know. Still, lets hope it does get off the ground (pun intended) and it's not put on the scrapheap like everything else it seems that is looking towards the future.

If anything needs investment then this is it. Not only government investment but from us all who want to make this work. I would. Even if the scramjet works for suborbital flight (think concorde with REL engines) then its going to change world travel in the same way as the jet engine did.
