The workhorse for the domestic Aeroflot network was a trijet, like its western counterpart, the Boeing 727. The Tu-154 has three engines at the back of the fuselage, two attached to the side and one in the rear fuselage, being fed by an S‑shaped duct with the air intake in front of the vertical stabiliser. Furthermore the Tu-154 has the typical Tupolev main landing gear which is retracted rearward in pods extending from the trailing edge of the wings. Both main landing gears have six wheel bogeys. Finally the Tu-154 is characterised by the sharp forward pointing bullet fairing on top of the vertical stabiliser.
The different versions of the Tupolev 154 can be distinguished by
- the shape of the nacelles
- the shape of the bullet fairing on top of the vertical stabiliser
- the number of emergency exits
- the presence of a cargo door in the left forward fuselage
Details will follow later.
Confusion possible with
The Boeing 727-200 is about the same size as the Tu-154 and has the same basic configuration. The main differences are in the main landing gear (on the 727 two wheels per leg, retracting inward) and the top of the vertical stabiliser (727 has no forward pointing bullet fairing).
Compared to the Tu-154 the HS121 Trident has different cockpit windows and landing gear. The main landing gear has four wheels on one axis and the nose gear retracts sideward.
Another Soviet built trijet but with more modern engines, featuring separate exhausts for the fan flow. Also, it has four wheels on each main landing gear leg (which retract inward), different cockpit windows and no bullet fairing on the tail.
