Mikoyan-Gurevich I.42/44 MFI
Designed as a replacement for the Su-27, the MiG 1.42 MFI (Mnogo-Funktsionalniy Istrebitel – Multi-Role Fighter) was publicly rolled out in January 1997.
The MiG 1.42 Mnogofunktsionalny Frontovoi Istrebitel (Multifunctional Frontline Fighter), or MFI, was designed as a response to the American F-22. Its makers, MAPO-MiG, say it will be able to outperform the most advanced US fighter, the F-22 Raptor. Like the F-22, the MiG 1.42 has a "thrust vectoring" system that gives it greater manueverability than current fighters. It also has similar stealth capabilities, employing composite materials, a special shape, S-shaped compressor channels, internal weapon storage, and perhaps an active radar cancellation system or a plasma cloud stealth system to avoid detection. Considering previous Russian fighters, such as the super-manoeuvrable Su-37, the MiG 1.42 will definitely enjoy greater manoeuvrability. Additionally, MAPO-MiG also claims that it would be stealthier than the F-22. And, since it is bigger, the MiG 1.42 will have a greater range. The MiG 1.42 is a twin-engine aircraft with a cranked delta wing, canards, twin tail fins, jet intakes under the nose, and 3D vectoring nozzles. It features the new Phazotron N-014 phased array fire control radar as well as a rear-facing N-012 radar.
The delta canard has a wing sweep of between 40 and 45 degrees, with a vortex generating dogtooth on the canard. The large wing of slender section, three sets of trailing edge control surfaces, and pronounced actuator fairings. External pylons are visible.
The stated intent of the delta canard configuration was to provide for excellent high AoA performance, and low supersonic energy bleed, by avoiding the trim drag associated with a conventional configuration.
The paired, outwardly canted vertical stabilisers are attached to a pair of large tailbooms, which house aft looking avionics and enclose the innermost trailing edge surfaces. Two ventral keels protrude beneath the vertical stabilisers, mounted on the tailbooms.
The aft fuselage is dominated by the paired and closely spaced Lyulka/Saturn AL-41F afterburning turbofans. These were to be fitted with circular thrust vectoring nozzles, which would be limited to 2D vertical vectoring should the tailboom arrangement be retained for production aircraft. The large single mainwhhels retract forward into the fuselage, close to the wing roots. The fuselage geometry provides for a modest inlet tunnel S-bend, which will reduce the inlet tunnel and compressor face RCS.
The inlets are variable, ventrally mounted, and feature a stepped multiple shock design. Two supporting struts, angled outward to reduce RCS, are employed to stiffen the inlet and nose structure. The clearance between the upper inlet lip and lower nose is intended to provide for good boundary layer separation at high AoA.
The structure is reported to comprise 30% composite materials, 35% aluminium lithium alloys, and 30% steel alloys.
Engine: 2 x Lyulka AL-41F turbofans, ~200kN
