A few designs for fictional futuristic Russian aircraft. Here are some technical summaries:
Sukhoi Su-41 (NATO Reporting Name "Feral") - A 5th-generation air superiority fighter, the Su-41 incorporates low-observable geometry, radar-absorbing materials and a structure made up largely of composites, titanium, and lithium-aluminum alloy. It is powered by a pair of afterburning turbofan engines equipped with three-dimensional thrust-vectoring nozzles capable of deflecting 20 degrees in pitch and 15 degrees in yaw. The high thrust and low drag of the aircraft allows it to supercruise without using the afterburners. An internal weapons bay reduces the drag and the radar cross-section (RCS) of the aircraft. The Su-41 has an active electronically-scanned array (AESA) radar and an avionics suite specialized in the air-to-air role. Data-linking with other aircraft is also possible.
Length: 72 feet, 6 inches (22.08 meters), Maximum Take-off Weight: 79,200 pounds (36,000 kilograms), Maximum Speed: 1,675 miles per hour (2,680 kilometers per hour) at altitude.
Yakovlev Yak-45 (NATO Reporting Name "Firefly") - Designed as a naval aircraft with stealth characteristics and short take-off vertical landing (STOVL) capability, the Yak-45 incorporates the advanced construction features common to other 5th generation fighters. The aircraft has two engines. The main engine is used for forward flight and can be vectored downward more than 90 degrees for vertical take-offs and landings. A second engine is positioned vertically behind the canopy and is used only for STOVL operations. A door on the top of the fuselage opens when this engine is in use. The aircraft is capable of hovering without using the afterburners. The Yak-45 features a Pelikan tail in place of a traditional tail. This reduces drag and RCS.
Length: 55 feet, 2 inches (16.8 meters), Maximum Take-off Weight: 55,000 pounds (25,000 kilograms), Maximum Speed: 1,250 miles per hour (2,000 kilometers per hour) at altitude.
Tupolev Tu-172 (NATO Reporting Name "Blindside") - A supersonic bomber with stealth capabilities, the Tu-172 is roughly the size of the Convair B-58 Hustler or Lockheed SR-71 Blackbird. Large delta wings yield room for a large fuel supply, giving the aircraft long range. A pair of afterburning turbofans are placed on the back of the jet in order to reduce the RCS of the aircraft as seen from below. The nozzles of the engines are embedded within troughs that are lined with heat-ablating tiles. This reduces the infrared (IR) signature of the aircraft when viewed from underneath. A supercrusing speed of Mach 1.5 is achievable as is a maximum dash speed in excess of Mach 2. As with any true stealth aircraft, the Tu-172 has an internal weapons bay (although hardpoints for external carriages also exist on the wings).
Length: 103 feet, 7 inches (31.5 meters), Maximum Take-off Weight: 180,400 pounds (82,000 kilograms), Maximum Speed: 1,430 miles per hour (2,288 kilometers per hour) at altitude.
Mikoyan MiG-39 (NATO Reporting Name "Fossa*") - The MiG-39 is a medium-weight, stealthy, multi-role fighter jet with short take-off and landing (STOL) capability. Its design features lambda wings, all-moving canards and a V-tail. Its single afterburning turbofan engine has a thrust-vectoring nozzle able to deflect 15 degrees in pitch only. The radar in the nose is a passive electronically-scanned array (PESA). Its avionics suite includes a "glass cockpit" and a capability for air-to-ground as well as air-to-air combat. A pair of tail-booms on the MiG-39 contain sensors which warn the pilot of threats coming from the rear.
Length: 58 feet, 3 inches (17.7 meters), Maximum Take-off Weight: 61,600 pounds (28,000 kilograms), Maximum Speed: 1,520 miles per hour (2,432 kilometers per hour) at altitude.
Antonov An-126 (NATO Reporting Name "Canyon") - A very large transport aircraft, the An-126 is designed to carry large payloads with increased fuel-burn efficiency and range. Advanced, high-strength construction materials decrease the empty weight of the airplane and allow for an increase in maximum take-off weight. High aspect-ratio wings equipped with winglets yield great lift efficiency. The V-tail allows for reduced weight and drag as it has only two stabilizers as opposed to a conventional tail's three. Computer control helps keep the aircraft on course and stable in flight. The four turbofans do not have afterburners and have an advance in overall specific fuel consumption when compared to earlier models.
Length: 220 feet, 9 inches (67.2 meters), Maximum Take-off Weight: 1,012,000 pounds (460,000 kilograms), Maximum Speed: 650 miles per hour (1,040 kilometers per hour).
*The fossa (pronounced "foo-sa"), after which the plane is named, is a weasel-like carnivore native to Madagascar.
