The Tupolev Tu-154 (NATO reporting name: Careless) is a Russian medium-range trijet airliner. It remains the standard airliner for domestic routes in Russia and other states of the former Soviet Union and to a lesser extent in eastern Europe and Iran.

The Tu-154 was developed to replace the jet-powered Tu-104, plus the Antonov An-10 'Cat' and Ilyushin Il-18 'Coot' turboprops. It is designed to operate from austere gravel airfields, to be able to fly at high altitudes above most Russian air traffic, and for takeoff performance.

The Tu-154 first flew on October 4, 1968. Regular commercial service began in February 1972, and production ended in 2006.^[1]

[edit] Design features

This section needs to be rephrased.

Its construction is sturdy, with 14 big low-pressure tyres enabling it to land on snow-covered unpaved runways without sustaining serious damage. Initially it had three rear-mounted Kuznetsov NK-8-2 jet engines, arranged similar to that of the Boeing 727, giving it a relatively good thrust-to-weight ratio. It has triple bogie main undercarriage units which retract into wing pods, and a T-tail empennage. About 900 have been built. Approximately 500 are still in service.

The comparable western counterparts of the Tu-154 are Boeing 727 and Hawker Siddeley Trident. The Boeing has better fuel efficiency and accordingly a greater range. The cabin of the Tu-154 gives the impression is of an oval interior, with a lower ceiling than is common on western airliners (Boeing or Airbus). The passenger doors are also smaller than on the Tu-154's western counterparts. Furthermore, luggage space in the overhead compartments is very limited.

The Tu-154's airframe and the landing gear is strong, since it is partially based on a design meant for bomber aircraft. In July 4, 2000, HA-LCR, a chartered MALÉV Hungarian airlines Tu-154 jetliner landed on its belly in Thessaloniki, Greece. The crew simply forgot to extend the landing gear and the plane skidded 400 meters (440 yards) on the runway. The plane became airborne as the pilots applied throttle, flew around and landed on wheels.^[2] There were no injuries, but it was deemed uneconomical to repair the aircraft for circa 2 million USD.

[edit] Variants

Many variants of this versatile airliner have been built. Apart from the normal differences between weights and powerplants, the Tu-154 was produced in variants which utilized exotic fuels. Like its western counterpart, the 727, many of the Tu-154s in service have been hush-kitted, and some converted to freighters.

[edit] Tu-154

The Tu-154 entered service with Aeroflot in 1972. Powered by Kuznetsov NK-8-2 turbofans, carried 167 passengers.

[edit] Tu-154A

The first upgraded version of the original Tu-154, the A model added centre-section fuel tanks and more emergency exits, while engines were upgraded to Kuznetsov NK-8-2U models. Avionics upgrades were also included.

[edit] Tu-154B

A 180 passenger model with modernised flight controls, added entry doors, and new spoilers.

[edit] Tu-154B-1

This version had uprated engines, and advanced operating equipment.

[edit] Tu-154B-2

This version has Western flight control and navigation systems, including a crosswind landing system and a new radar system.

[edit] Tu-154S

The Tu-154S is an all-cargo or freighter version of the Tu-154B, using a strengthened floor, and adding a forward cargo door on the port side of the fuselage.

Two prototypes based on this aircraft are the hydrogen- or natural gas-powered Tu-155 and Tu-156. The Tu-155 prototype uses natural gas, or methane, fuel for its central engine, and made its maiden flight in the late 1980s. In the Tu-156 all three engines are adapted to burn either hydrogen or natural gas. Cryogenics technology to store the liquid fuel is used in the development of both Tu-155 and Tu-156.

[edit] Tu-154M

Currently, the Tu-154M is the production standard which first flew in 1982. It uses more efficient Soloviev D-30KU turbofans. It is far more economical, quiet, and reliable than previous versions. Aeroflot consistently achieves dispatch reliability above 99% with the Tu-154M, which compares favorably with current western airliners. The original designation was Tu-164.

[edit] Tu-154M-LK-1

VIP transport version.

[edit] Tu-154M2

Proposed twin engined version, to be powered by two PS-90A turbofan engines.

[edit] Tu-154-100

Design with modernised cockpit and redesigned cabin.

[edit] Incidents

This section documents a current event. Information may change rapidly as the event progresses.

Since first delivered for service 63 TU-154s have been lost to accidents, which is above the average for the comparable Boeing aircraft (e.g. 6.8% of Tu-154 planes ever built have been counted as hull losses versus the figure of 5.5% for Boeing 727). However 28 of 63 losses were with no human fatalities. Six of the 63 losses were the result of terrorist or military shootdowns and several were notably the result of poor runway conditions, including one which struck snowplows left on the runway. Others losses came as results of mechanical problems, piloting errors, faulty air traffic control, including a mid air collision in July 2002, etc. ^[6]

On August 22, 2006, while en route from the Russian Black Sea port of Anapa to St. Petersburg, Pulkovo Airlines Flight 612 crashed near the Russian border over eastern Ukraine. All 160 passengers and 10 crew were killed.

Eleven days later, on September 1, 2006, an Iran Air Tours Tu-154 skidded off the runway as it was landing in Mashhad and caught fire. A tire had blown on the aircraft during landing. The aircraft was carrying 147 passengers, 29 of them died in the accident. Mashhad, located 620 miles northeast of Tehran, is visited by some 12 million people annually on pilgrimage to its Shiite Islamic shrines.

On 26 September 2006 a Kyrgyzstan Airlines Tupolev Tu-154 aircraft taking off at Bishkek (bound for Moscow with 52 passengers and 9 crew on board) lost part of its wing in a collision with a USAF Boeing KC-135 tanker. The aircraft was able to take off and return to make a safe landing with a 2.5m part of the wing cut away. ^[4]
