Development

Work on the Tu-404 was initiated in 1991 in parallel with another widebody design, the Tupolev Tu-304. The Tu-404 was designed to transport more than 1,200 passengers to destinations 12,000 - 13,000 km away. The Tupolev Design Bureau investigated several possible configurations for the Tu-404, including a flying wing and a conventional design. The flying wing's powerplant would consist of six pusher turboprop engines developing 18,000 kg of thrust each during take-off and each consuming only 0.644 kg/kgf-h of fuel in cruise mode. The engines would have been located in the tail section of the flying wing fuselage between two large V-shaped vertical stabilizers. The central fuselage contains six passenger compartments accommodating 1214 passengers. The leading edge of the central fuselage has a sweep of 45 degrees. Two large removable wings containing fuel tanks have the leading-edge sweep of 35 degrees and are attached to the central fuselage. The wings hold most of the aircraft's fuel.

The conventional design featured a two-level passenger aircraft capable of transporting 1,200 people to destinations of up to 10,000 km. The lower level of the fuselage was designed as a multi-section cargo compartment for transporting cargo in standard aviation containers. Two sub-variants of this design were investigated, a mixed passenger-cargo aircraft with the enlarge cargo section and a dedicated cargo model. The massive low-level wing with a leading-edge sweep of 35 degrees and vertical wingtips has massive control surfaces: multi-section leading-edge control surfaces, low-speed control areas, multi-section flaps. Each half of the altitude control surface is made of two sections.

Proposed powerplants included four Kuznetsov NK-44 or Rolls-Royce "Trent" engines installed on underwing pylons. The aircraft's undercarriage consisted of several carts with multiple wheels in each cart. It is retracted into the central fuselage section of the aircraft. [2]

The project did not proceed beyond the stage of marketing models.

Douglas DC-8 Jet airliner family

The Douglas DC-8 is a narrow-body airliner built by the American Douglas Aircraft Company. After losing the May 1954 US Air Force tanker competition to the Boeing KC-135, Douglas announced in July 1955 its derived jetliner project. In October 1955, Pan Am made the first order along with the competing Boeing 707, and many other airlines followed. The first DC-8 was rolled out in Long Beach Airport on 9 April 1958 and flew for the first time on 30 May. FAA certification was achieved in August 1959 and the DC-8 entered service with Delta Air Lines on September 18.

Tupolev Tu-114 Soviet long-range turboprop airliner

The Tupolev Tu-114 Rossiya was a turboprop-powered long-range airliner designed by the Tupolev design bureau and built in the Soviet Union from May 1955. The aircraft was the largest and fastest passenger plane at that time and also had the longest range, at 10,900 km (6,800 mi). It has held the official title of fastest propeller-driven aircraft since 1960.

Tupolev Tu-154 Airliner by Tupolev

The Tupolev Tu-154 is a three-engine medium-range narrow-body airliner designed in the mid-1960s and manufactured by Tupolev. A workhorse of Soviet and (subsequently) Russian airlines for several decades, it carried half of all passengers flown by Aeroflot and its subsidiaries, remaining the standard domestic-route airliner of Russia and former Soviet states until the mid-2000s. It was exported to 17 non-Russian airlines and used as a head-of-state transport by the air forces of several countries.

Lockheed L-2000 Proposed US supersonic airliner design

The Lockheed L-2000 was Lockheed Corporation's entry in a government-funded competition to build the United States' first supersonic airliner in the 1960s. The L-2000 lost the contract to the Boeing 2707, but that competing design was ultimately canceled for political, environmental and economic reasons.

Tupolev Tu-80 Prototype for a longer-ranged version of the Tu-4 bomber

The Tupolev Tu-80 was a Soviet prototype for a longer-ranged version of the Tupolev Tu-4 bomber, built after World War II. It was cancelled in 1949 in favor of the Tupolev Tu-85 program which offered even more range. The sole prototype was used in various test programs before finally being used as a target.

The Tupolev Tu-75 was a military transport variant of the Tu-4 bomber, as was a similar airliner, the Tu-70, both using a new, purpose-designed fuselage. The first Soviet military machine of this class, it was equipped with a rear fuselage loading ramp. It was not placed into production because the VVS decided it would be cheaper to modify its existing Tu-4s for the transport mission and to use its existing Lisunov Li-2 and Ilyushin Il-12 transports.

The Tupolev Tu-70 was a Soviet passenger variant of the Tu-4 bomber and designed immediately after the end of World War II. It used a number of components from Boeing B-29s that had made emergency landings in the Soviet Union after bombing Japan. It had the first pressurized fuselage in the Soviet Union and first flew on 27 November 1946. The aircraft was successfully tested, recommended for serial production, but ultimately not produced because of more pressing military orders and because Aeroflot had no requirement for such an aircraft. A military cargo aircraft version was the Tupolev Tu-75.

Airbus A310 MRTT Airbus A310 Multi-Role Tanker Transport (MRTT) air to air refuelling tanker / transport aircraft

The Airbus A310 MRTT Multi-Role Tanker Transport is a military air to air refuelling, or in-flight refuelling tanker transport aircraft, capable of operating multi-role missions. The A310 MRTT tanker aircraft is a subsequent development from the earlier Airbus A310 MRT Multi-Role Transport, which was a military transport aircraft for passengers, cargo, and medical evacuation. The A310 MRT and A310 MRTT are both specialist military conversions of existing airframes of the civilian Airbus A310-300C wide-bodied passenger jet airliner.

Tupolev Tu-334 Airliner by Tupolev

The Tupolev Tu-334 was a Russian short-to-medium range airliner project that was developed to replace the ageing Tu-134s and Yak-42s in service around the world. The airframe was based on a shortened Tu-204 fuselage and a scaled-down version of that aircraft's wing. Unlike the Tu-204, however, the Tu-334 has a T-tail and engines mounted on the sides of the rear fuselage instead of under the wings. With the rationalisation of the Russian aircraft companies in 2009 to form United Aircraft Corporation it was decided not to continue with the programme.

Tupolev Tu-244 1979–1993 proposed supersonic passenger airliner

The Tupolev Tu-244 was a proposed supersonic transport (SST) aircraft, developed from the Tu-144. It implemented novel features such as cryogenic fuel to enable flight distances of up to 10,000 km (6,214 mi) and would have carried up to 300 passengers. The project was cancelled in 1993.

The Tupolev Tu-2000 was a planned hypersonic flight experimental aircraft designed by the Tupolev design bureau. It was intended to test technologies for a single-stage-to-orbit aerospaceplane and also the Tupolev Tu-360 intercontinental bomber.

Tupolev Tu-12 Experimental Soviet medium bomber

The Tupolev Tu-12 was an experimental Soviet jet-powered medium bomber developed from the successful piston-engined Tupolev Tu-2 bomber after the end of World War II. It was designed as a transitional aircraft to familiarize Tupolev and the VVS with the issues involved with jet-engined bombers.

The Ilyushin Il-46 was a jet-engined bomber produced in the USSR during 1951-2, as the result of a directive to redesign the Il-42 project. The revised specification was for an aircraft with twice the range and 1 1/2 times the bomb load, with a prototype ready to be submitted for state acceptance trials in July 1952. The Ilyushin design bureau set about designing two versions of the same aircraft, the straight-wing (Il-46) and the swept-wing (Il-46S), with as much as possible common to both aircraft. To meet the schedule for state acceptance trials Ilyushin built only the straight-wing version, fearing that the design, manufacture and flying characteristics of the swept-wing aircraft might cause delays.

Ilyushin Il-18 (1946)

The Ilyushin Il-18 was a Soviet four-engined airliner designed and built by Ilyushin immediately after World War II. Although the aircraft itself was successful, its Shvetsov ASh-73TK engines were too unreliable for civilian use and were further needed to equip the Tupolev Tu-4 bomber, so it was cancelled in 1948.
