F-22 frontal RCS = ‘size of a marble’ = ~0.0001-0.0002 sq m
F-35 frontal RCS = ‘size of a golf ball’ = ~0.0014 sq m

This values are wide interpretable.
The stated metall golf ball is not only so great as a real golf ball.
This is a bad example for me. Why? This corresponds to a RCS like a physical dimensions value like a strandball at some frequencies.
Marbeles are interpretable two, the standard marble has a 600% greater RCS as the physical dimensions.

In fact this RCS claims are useless!

He was decrying conventional fighters for having horizontal tail surfaces, yet ignoring the Eurocard’s horizontal nose surfaces (canards). Yes, I know canards are smaller.

But where is the rudder at a canard? A small but big difference!
A conventional tail plane acts as cat eye a canard not through the absence of a counter reflector. A V-Tail make this even worser, the best way for a low RCS tail plane is a roof tail but this is a IR-reflektor and IR-amplifier and therefor a big no go. But the best tail is tailless –> B2.

Planform aligment do not decrease the RCS, planform aligment increase the RCS in this cumulated point. The meaning behind it, that incoming radar wave is scatter away from the front quater and focused in a harmless area.

Then notice
The laws of physics maintain that energy must be conserved. If the monostatic RCS is reduced by shaping,
the incident energy must be distributed elsewhere. As such, the target signature is increased at some or all bistatic angles.

What mean that for scattering stealth, used at F-22 and F-35?
The have a greater bistatic RCS. :rolleyes:

The fat stealth fuel-guzzler are a perfect target for a QWIP IRST.

ZAGI says the AN-70 has a great design failure.
Blown leading edge flaps make hedaches when an engine is faild and with two faild engines ends this disastrous. 😉

Against EU support for Greece speak, there is general reservations. All EU countries are suffering from financial problems, and it is not easily communicated to taxpayers that they need to help Greece!;)

Well someone has and that nation is called Germany!!! With a few other helpers along the way…………..

But the Euro no-bail-out agrement prohibits state aids for Greece.

Greece has well known the Euro access surreptitious with faked economic data.
Therefore should Greece ruled out of the Eurozone and this a possible worst case scenario for Greece.

The Greece debt 302 Mrd Euro
http://www.spiegel.de/wirtschaft/soziales/bild-677319-57832.html
Average debt ratio: 112,6 % of the national of the gross domestic product GDP
GDP-increase 2009 = -1,1%
Share at GDP Euro- Zone only 2,6% (2008)

Greece is bankrupt!
Let it die.

can you send an email to the usaf usmc usn australia singapore, [who else is buying aesa right now?] for me and tell them what a terrible mistake they have made and how stupid they are
its all starting to makes sense to me now, i wonder why everyone wants to go aesa, must be just a phase:diablo:

No Notrop Gruman is a slightly bit smater as you and use the high beam agilty and do not degrade the high gain and resolution through fragmentation.:diablo:

We heard several times on that forum, and using information from Thales documents, how the RBE2 was a PESA with a “limited” pure range because of its two “déphaseurs” ( ?? sorry, I forget the word in english) which implies more loss than what would have been possible with another kind of PESA but it was DECIDED like that.

Anyway, now, an AESA will get rid of those elements, so that, the minimum of gain I have read about the RBE2 AESA is around 30%.

The RBE2 phase shifters based on pin-diods. The russian use pin-diods only in the y-plane. In the x direction are ferrit lenses used. PIN-diods are fast but produce much heat.

Of course we know the characteristics of TWTs and MMICs.

Which is why we know that the Mig-25 figure is obvisouly a mistake, a 600kW output power radar would require cooling for another 600kW heat given the actual efficiency of TWT and coupling in a MSC/PESA radar.

This is peak power not averange power. Since the russian lacks in digital technic at this time the had no puls compression. For a good range discrimination are either short pulses with high power or intermodulation (pulscompression) in the Radar pulses and therefor low power.;)

PS. AEGIS has a peakpower of 4-6MW and an averange power of 58kW.
