Superconducting materials have special radar absorbance properties by exploiting the inefficiency of high temperature superconductors above their Tc (critical temperatures). It has been shown that the RCS is reduced as the magnetic field increases -in turn increasing the surface resistance within the magnetic field. The effect is more pronounced as radiation resistance decreases and superconductors are particularly efficient at absorbing X-band (microwaves), exhibiting behaviour akin to radar absorbing lossy magnetic materials such as carbonyl & ferrite iron that respond to the magnetic field in a microwave.

To date, using superconducting materials for stealth applications have been focused on the aircraft’s antennas, in an attempt to address the problem of scattering and turning the absorbed radar waves to thermal energy.

Magnesium Boride/diboride (Mg-B) properties as a superconductor have only recently been discovered (2001), it has broken new ground for superconductivity based on the well known electron-phonon interaction and hence would be particularly efficient at radar absorbance.

OAO ‘NPP Motor’ in association with the Ufa State Technical Aviation University have established a working fan-blade of the [engine] compressor’s first stage based on a magnesium boride matrix (Mg-B) and reinforced carbon fibre composite. Note the carbon fibre composite is low reflective. This has been around 5 years in the works.

‘NPP Motor’ are a contractor for the PAK-FA Stage 2 engine.

I triple checked everything- it’s the real deal.

Superconductors require cryogenic temperatures to work. You’re not going to get that in jet engine fan blades.

The panel from the photo seems to be 1 cm thick.
I recall DjCross when T-50 flew first saying that from panels thickness one could approximately give what kind of band radars the platform will be invisible.Can somebody confirm this and what would be the target?
Sorry if the assumption sounds silly

This is true, but only to a certain extent. Convenctional RAM requires a certain thickness to be effective (I think on the order the wavelength/2 or the wavelength/4 IIRC). This is also true of conventional Jaumann absorbers. However, comparatively new (that is to the conventional Jaumann absorber) capacitive Jaumann absorbers do not require this. This is what the F-35 is rumored to use, and it would make sense for the T-50 to use the same.

I thought the J-10b is going to be exported to Pakistan as the FC-20?

I cannot do Calculus with Excel

Try dx*SUM([function values]).

No, it’s the AVIC JF-17’s DSI, since JF-17 prototype PT-06 flew over 3 months before F-35 prototype AA-1 did. 😉

Yeah… no.

I think Tu-214 is cool. Maybe Russians can experiment with a Phalcon style lay out like the Singaporeans..

I’d like to see that on the SSJ-100.

What does the Rafale have for a short-range HOBS missile? I mean something like IRIS-T, AIM-9X, Python 5 would seem to be a natural couple for for the upcoming HMD for the Indian Rafale.
