A few things I would like to blog about:
- Sorry, but the F-35 is Fat and UGLY. But I do admit it have some good sides.
- F-22, superior or not?
- PAK-FA, how good is it?
- Affordable General Aviation.
- Composites or Aluminium?
Some day, some day....

So much to blog about, so little time...
Been busy doing all possible things but surfing the net so...
A few things I would like to blog about:

How can the Gripen supercruise when the F-35 can't?*
The F-35 have in excess of 28000 lbf dry and the Gripen Demo have about 15000 lbf dry.
This makes it look like the F-35 should outrun the Gripen any time, still the official figures does not confirm this. Why?
This is my five cent:
The wing is about the same size, the length of the aircrafts are comparable but when you look at the aircrafts head on something else dawns: the Gripen has a tiny frontal area compared to the F-35 and even that is not the whole truth, since there is a major coke bottle shaping starting behind the canards.
This means that even if the skin friction is comparable and the shape friction is not that much better for the Gripen, the wave drag will be much less.
There are thousands of other details, like the thrust characteristics of the engine, wing thickness, mach cone, weights and stuff, but slenderness is always good when you wants to go fast.
*Well, I'm pretty sure that the F-35 can supercruise to some extent, but I think it will only be in a limited temperature and altitude envelope.

Just got to recommend this link...
If you're a airplane nerd like me, this is an exelent link:
http://www.up-ship.com/drawndoc/drawndocair.htm
What do you find when you click on the link?
Airplane cut away drawings and description documents, but not the regular F-16 and so on but more exotic aircrafts like the YF-23, Northrop N-126 Interceptor , Vought V-507, Convair flying submarine report and other airplanes that you hardly have heard of.
Great!
I downloaded a copy of some YF-23 drawings, and printed them in extended A0 format, (that is 0.8 by 3 meters!).
The drawings were not correct to the prototype, but I still think it was worth the $7 that I payed.

A grand day out
Skipped the computer today and did some hands on myself.
A bit cloudy and a tad dirty windscreen, but with a view like this, who can complain?

First Post
A little blog about Airplanes, flying and other technical things interesting to me is about to be created here.
Don't hold your breath for updates, it might be a long time between posts.
My English is not perfect, far from, but I will do my best to make myself understood.
Let's get started.
