For All You Hypersonic Glider Builders
Posted in Homebuilt, airplane, tagged Boost Glide, hypersonic, NASA on Friday 2009.09.11 | Leave a Comment »
If you use a fifties shape, active roll damping is a really good idea at subsonic speeds at least. Old NASA video of some wind tunnel flying models. (via Secret Projects forum)
Hydrocarbon Scramjet Already Flown

By ATK in 2005. Shows how little I know.
EDIT: Spaceref had the details, Mach 5.5.
(Scramjets are still not a space application.)
Paramotoring Over The Wintry Helsinki

Some pics from some guys who travelled to here from midwest Finland. It doesn’t look that glamorous since the weather is cloudy. At least a proper winter this year (last winter there was practically no ice at all.) Some of the pics are from Espoo too (the neighbouring city where I currently live).
The snow kinda [...]

Nice video explanation of the SABRE engine by Richard Varvill.
In a sense, it boils down to the problem of changing the hot fast low pressure intake air flow to a cold slow high pressure flow.
In the Sabre engine, techniques somewhat similar to liquid air plants are used: there is a compressor, that is coupled to [...]
Simple Materials

I’m fascinated how some people still nowadays build a vehicle out of wood, strap a small engine onto it and dash through skies at 200 km/h speeds. Very few tools are needed for wood working, although a lot of time has to be spent. There are some modern materials, like glues (usually epoxies) used in [...]
Aluminium Alloys

or aluminum, as they say in the US.
It was a bit weird experience researching this on the internet a while back, so I thought maybe a short recap is useful.
Basically, clean aluminium is quite weak. If you [...]
There Are Failures

In every endeavour. Yet the viability of the whole can not always be deduced from them.
The Armstrong-Whitworth Ensign, Bristol Brabazon and Saro Princess all flew but none operated for real. Yet machines like DC-3, Lockheed Constellation or even the Boeing 707 were successful. [...]
Swedish Missiles, Changing a Ship’s Course
Posted in Architecture, Demotivation, NASA, airplane, tagged ares i, sweden, missile, air defence on Friday 2008.12.05 | 1 Comment »
Some years ago, Sweden had a plan to defend their air space with a vast network of radars at cellular phone network masts coupled with very fast missiles. And whaddya know, now Swedish missile oxidizer technology is finding itself to Ares I. I don’t know if it’s from the same missiles.
Ares I is becoming a [...]
