Fortran 90 is a great language for numerical analysis because of it’s matlab like array handling capabilities and ability to split the algorithm for multi-cpus but the chances of it being used in a missile somwhat escapes logic.
Great pictures.
A few questions
1. How much was the distance that Mig-25 had to cover to reach japan
2. Why Russians were’nt able to shoot the aircraft, the moment they noticed defection.

There is nothing really wrong with all metallic design. I have been doing some research works at IFQ in Germany during my studies (Boronepoxide, Hohlkugelkomposite, mostly for aerospace and robotic industry) and besides many advantages we have also found various drawbacks. Any long thin *skinny* structures are absolutely inappropriate for composites as they feature very low Young’s modulus and require large cross sections to keep the construction stable. They feature excellent damping characteristics at high frequencies and they have a big technological advantage that they are casted in cold state as they harden due to various chemical processes. Therefore no thermal energy and no expensive metal cast forms are necessary.
We have tried to build a robotic twin arm purely of composites, tried to reinforce the damn thing with glass and carbid phasers but it has proven impossible to get the things right without the vital parts (mostly attachment points) being made of aluminium or even steel.

Why are you speaking about almost 30yrs old Su-27? This is very little representative for the 21st century. Current Su-30MKI feature N011M BARS radar with passive phased array (330km search against a F-15-sized target, 4 targets simultaneous tracking (8-target with development prototypes)). That is one of the best devices currently available, being outclassed only by AESA types like APG-77, so where is the problem, then?
1: The bottom line is that composites are the future, no matter how difficult the technology is. All future aircrafts will use it.
2:BARS is a very good radar in terms of range. However it has been said that it does not posses all modes that western radars have. Finally a decade from now when active phase radars will become common, BARS will loose much of it’s luster and perhaps Russia won’t be able to field an active array, relegating it again behinf west.
There’s nothing inherently wrong with an all-metallic build. ‘Composite’ might sound sexy but it’s not a magic word denoting inherent superiority. Regardless, the Su-27 is not a Russian aircraft, it’s Soviet. Development programs carried on by Russia from the Soviet Union (Su-30MK, Su-35, MiG-29M1/MiG-29M2) do not have poor avionics, poor MMI, or low engine life.
Furthermore, it ain’t like any Western aircraft besides the F-22, F-117, and B-2 can seriously claim to not have a ‘huge RCS’. In other news, the Russians recently reduced the RCS of an Su-35 by half through application of RAM.

China is exponentially improving, while Russia/west linearly, I’d say with in 10 years there will almost be a parity.
——————————————————————————–It’s easy to exponentiallly expand in comparison with more developed players, because you had nothing special to begin with, anything you do is an improvement. Regardless, in 10 years time the USAF will have the F-22 in established service, with the PAK FA probably in flight tests (the Russians are hoping to have it ready sooner, but really, let’s be realistic). To think that China can reach that technology level in a decade is *way* too optimisitic (it also presupposes that China’s economic honeymoon will continue indefinitely which is not guaranteed, though I’d say it was a guarantee until at least 2008, for obvious reasons).
First of all, I have personally great respect for Russians, however denying obvious facts is no good.
Composites may have their problems, but then west is using it, and not with out good reasons, what ever can reduce the weight ought to be used. Mastery of composites is must for superpower. PAK-FA will also use it. But then west again has a lead here.
Radars: The passive-phase array antenna is a really good achievement however it is teamed with poor cpus and signal processors, denying the phase array antenna to show it’s true glory. I may be wrong, but I read some where that Indians are planning to replace the cpu/processor of Bars radar.
SAR feature is also notably poor on Russian radar.
ECM/ECCM: Su-30 MKI is using Israeli equipment, not russian.
Poor MMI: Notable achievements have been made in MMI department recently. However compared to west, there is still something lacking. Compare the cockpit of rafale with su-xx to see what I mean. Also the pilot seat is upright.
Engine life: A really big issue. India and China can attest to that. Also please note that in commercial aviation, western engines are hughely superior to Russian ones.
You are right that new players can expand exponentially, the point is that where will be China 10 years from now compared to Russia. My idea is that in a world increasingly dominated by electronics, Russia is increasingly looking backward. One big edge that west had always over USSR was electronics.
In terms of ideas, Russia is super power in the league of US, in terms of implementing technology it is even behind some small european countries.

[I]Russia I still beleive is No.2 in aviation followed by Dassault, then European Union. China I would say in top 4 or 5. [/]
Yes but it is fast lossing it’s edge. It has great width of technology in that it makes every thing from aircrafts to spaceships. But once it comes to vertical depth i.e. quality it has probelms, Su-27 is a great concept implemented poorly. e.g poor avionics, huge RCS, poor MMI, low engine life, all metallic build. Imagine what this aircarft may have turned out to be if built by west.
China is exponentially improving, while Russia/west linearly, I’d say with in 10 years there will almost be a parity.
Speaking of radars, why don’t China and Russia jointly undertake a development. Russian passive array antenna (pero ?) can be combined with chinese electronics to come up with something that’s a credible alternative to western radars.
