Many of you probably know about aerogel. It was completelly new to me when I found it on wikipedia last week. But I don't know how many of you have
ever heard of silica nanofoam...
However these two materials offer many new options in designing aircraft... As you know the density of the air is 1.2 mg/cm3. The density of aluminium
is 2.7 g/cm3 and density of titanium is 4.1 g/cm3. It means that airframe made of aerogel would be at least 2000 times lighter than today's usual
airframes... In wikipedia article you have a photo of a 2g piece of aerogel supporting 2.5 kg brick. That means that it maybe can't sustain pressures
at high supersonic speeds, but it definitelly would sustain pressure at high subsonic speeds... Aerogel is also one of the best (in guinness book
listed as the best) heat insulator. Wouldn't use of such a material greatly affect the range and fuel consumption of b-2 bomber-like aircraft??
But that's not all... The next material is called SILICA NANOFOAM...it has a density of 1.0 mg/cm3, which makes it LIGHTER THAN AIR!! This
material is still only in labs, but it offers you making a solid aircraft that is lighter than air: can hover without consupting any fuel, can be
easily accelerated, ... But eventhough it's still just in labs, many times in history something that was only just in labs in white world could be at
the same time in operational use in black wolrd... The only problem you have to solve is fuel, 'cause you can't have fuel tanks (they weight too
much).. but you can have solar cells... you would have to have 1000m3 to support 2 tons of equipment... it's not that much...it's 10x25x4 meters...
Just imagine phoenix lights, UFO over europe, which could hover and accelerate extremely rapidly... it could all be done with such materials...
Does anyone have any more info??any more pros?? any contras??
