Mikoyan Project 1.44
https://en.wikipedia.org/wiki/Mikoyan_Project_1.44
The Mikoyan Project 1.44/1.42 (NATO reporting name: Flatpack) was a technology demonstrator developed by the Mikoyan design bureau. It was the Soviet Union's answer to the U.S.'s Advanced Tactical Fighter (ATF), incorporating many fifth-generation jet fighter aspects such as advanced avionics, stealth technology, supermaneuverability, and supercruise. The design's development was a protracted one, characterised by repeated and lengthy postponements due to a chronic lack of funds; the MiG 1.44 made its maiden flight in February 2000, nine years behind schedule, and was cancelled later that year. Preliminary design The MiG 1.44 had its origins in the early 1980s, when the U.S. Air Force began developing a fighter under the Advanced Tactical Fighter (ATF) project, which would result in the supermanueverable and stealthy, albeit costly, Lockheed Martin F-22 Raptor. Consequently, the Soviet government tasked its fighter design bureaux the job of developing a fighter with which to counter the American threat, and replace the Sukhoi Su-27. Mikoyan occupied itself with two concurrent projects, one of which focused on a heavy multi-role design designated MFI (Mnogofunksionalni Frontovoy Istrebitel, "Multifunctional Frontline Fighter"), the other a light tactical fighter named LFI (Lyogkiy Frontovoy Istrebitel, "Light Frontline Fighter"). To minimise costs, both designs were to share as many components as possible. However, as the research and development phase for the two projects progressed, costs escalated due to the complexity normally associated with advanced aircraft projects. As a result, the Soviet government created the Combined Task Programme in 1983 with the aim of maximising efficiency and developing technologies to be used for all classes of aircraft. Mikoyan became the primary contractor for the programme, the importance of which was illustrated with its inclusion into the Soviet five-year economic plan. The design bureau soon formulated initial specifications for the new fighters. Mikoyan proceeded with the preliminary design of both the MFI and LFI with participation from numerous institutions, which assisted in the progressive definition of the designs. TsAGI (Tsentralniy Aerogidrodinamicheskiy Institut, "Central Aero- and Hydrodynamic Institute") was responsible for collecting wind tunnel test results, which, along with theoretical studies, were vital during this phase of development. The institution recommended that Mikoyan include canards for the MFI, since it offers great agility and lift, the latter important as the MFI was a statically unstable design. The delta wings then had a wing leading edge sweep of 40–45°. During this period, engineers undertook unprecedented wind tunnel testing to refine the MFI's aerodynamics and verify its radar cross-section (RCS). The MFI would have a variable engine intake ramp located under the front fuselage, reminiscent of the Eurofighter Typhoon; this was particularly important with the nature of the aircraft, since it allows for sustained air flow into the engine during sudden manoeuvres. As for the engine themselves, research was conducted on thrust vectoring, allowing for markedly improved manoeuvrability and short take-off and landing performance. Besides the mechanical and aerodynamic aspects of the design, engineers investigated hundreds of issues to refine the layout and specifications. In 1987, Mikoyan and the associated institutions submitted the MFI and LFI proposals for review. Design The MiG MFI was a delta wing, twin-tailed, fifth-generation air superiority/strike fighter design that incorporated advanced technology to theoretically give the aircraft excellent stealth and fighting attributes. It featured a close-coupled canard layout which, when working with the vectorable engines, gave the aircraft remarkable maneuverability. The aircraft had a tricycle landing gear system, with a single, dual-wheel landing gear in the front, and two single wheels in the rear. The MFI had relaxed stability and was controlled by a fly-by-wire flight control system. Mikoyan made use of weight-saving materials in the construction of the aircraft, with aluminium-lithium alloys making up 35% of the empty weight, steel and titanium alloys (30%), composites (30%) and others (5%). The MiG MFI was unconventional in its layout, in an effort to improve in-flight efficiency and stealth characteristics. Efforts were made to minimise surface-area, possibly to reduce drag. The wings were of delta planform, with leading-edge sweep at 52°. At the tips were dielectric fairings which housed electronic countermeasures/electronic support measures. The wings had full-span leading-edge flaps. The canards, meanwhile, had a leading-edge sweep of 58°, and had prominent dogtooth which improved airflow over the wings at high alpha (angles of attack). Russian aviation experts claim that the unorthodox design, use of radar-absorbent materials (RAM), and internally mounted weapons, gave an radar cross-section (RCS) of less than 0.3 m2 (3.2 sq ft), comparable to that of the F-22 Raptor. The RCS falls to 0.001 m2 (0.011 sq ft) with the use of a plasma shield. The fighter is equipped with a glass cockpit and features a Pulse-Doppler radar. The N014 radar, with a range of 420 km (260 mi) and target detection from 250 km (160 mi) to one metre (3.3 ft), was able to track up to 40 targets and shoot against 20. The radar system has a passive electronically scanned array antenna and is linked to a fire-control system. The 1.42/1.44 fighter is believed to have evolved into the Mikoyan LMFS fifth-generation light fighter project. Some Russian military analysts believe that the Chinese fifth generation J-20 drew heavy inspiration from or was fundamentally based on the MiG 1.44, citing similarities in its canards, tail section, and "duck like" aerodynamic design.
