AESA Radar to India

MiG-35? Could someone explain to me what you mean with that one? (Ok, I know this is an one-liner but I don't have anything more to ask...)

swimmer had a thread about it. its called the mig-29 ovt, which is basically a mig-29 with enhanced avionics and moreimporatantly, tvc. the engine only swivels 15 degrees each direction, so the tvc isnt as advanced as the su-37 one, but its still pretty lethal on a plane as manuverable as the mig-29. russia is offering the plane to india as cheap competition to the f-18.

acutally the TVC on Mig35 is more capable as its an all aspect TVC.. while the one on SU37 can move vertically or horizontally or just one direction(vertically) depending on the version.

nope. the su-37 us a 3-d tvc, with 15 degrees side and 30 degrees(correct me if im wrong) up and down. the migs is only a semi 3-d tvc, which swivels the nozel rather than the entire engine.

The Su-37's AL-31FU TVC is not 3D, in fact it's the same engine used on the Su-30MKI but slightly modefield (the Su-37 uses AL-31FU, while the Su-30MKI uses AL-31FP), the RD-33 OVT used on the MiG-35 is a fully 3D engine, being able to move up to ±15º within the vertical plane and up to ±8º within the horizontal plane. While the AL-31FP can only move to ±15º within the vertical plane.

AL-31FP is a high temperature by-pass engine of modular design. A specific feature of Saturn AL-31FP is an axisymmetric vectoring nozzle with a thrust vector angle of ?15? in the vertical plane providing super maneuverability of the aircraft. The vectoring nozzle control is integrated with the engine control system. AL-31FP engines ensure stable operation in all available evolutions of the aircraft in super maneuverability modes. Saturn AL-31FP engines power advanced multipurpose Su-30MKI and Su-37 fighters...

The nozzles are designated KLIVT (Klimov Vectoring Thrust). In the KLIVT system, the nozzles are not totally movable (as in the case of the AL-31FP engine of the Su-30MKI), but only the rear section part of the nozzles. They can be moved in all directions (up to ±15º within the vertical plane and up to ±8º within the horizontal plane) and not only within the vertical plane as in the AL-31FP engine. The nozzles can be moved at any position of the engine throttle, including during full afterburn.

From this thread.

ok, i looked it up on global securities and it appears your right.

so can we get back to aesa radar now? hows chinas aesa comming along? russias?

Actually AL-41F1 to be put on 35bm is fully 3D TVC for sure, so that's why I have been advocating for China to get that plane.

As for AESA radar, the Russians are definitely developing AESA, but the progress is questionable. If you look at their radar in service, even Bars isn't 100% ESA. All their new radars, Irbis and Sokol are supposed to become PESA. We wil see. These radars have been talked for a long time, but who knows when they will be ready. I read recently the problem with Chinese ESA radars in general is overheating. Apparently, they can keep it working long enough to be certified. If you noticed, most of the Chinese mechanically steered ones have a non-stopping working hour of 150 hours. Who knows how far the PESA radars are at. As for AESA, the issue is cost. The T/R modules are still too expensive.
