Tu-124 Tupolev
Tu-124
ASCC codename: Cookpot
Short to Medium-Range Jetliner

DESCRIPTION:
The success of the medium-range Tu-104 led Tupolev to develop a derivative to meet an Aeroflot requirement for a short to medium-range airliner to replace the Ilyushin Il-14. While a completely new aircraft, the Tu-124 was essentially a 75%-scale variant of the Tu-104, and the two were difficult to distinguish from a distance.

In comparison with the larger aircraft, the Tu-124 introduced several aerodynamic refinements including extension of the wing trailing edge roots and addition of double-slotted flaps, automatic lift dumpers, and a large center-section airbrake to improve takeoff and landing performance. The Tu-124 was also fitted with a brake parachute for use in case of emergency landing as well as low-pressure tires for rough-field operations. In addition, the Tu-124 introduced much more fuel efficient turbofan engines, being the first short-range jet aircraft in the world to be so equipped.

The initial production model carried up to 44 passengers while the definitive Tu-124V could handle 56. Other notable variants included the Tu-124K and Tu-124K2 VIP transports and Tu-124Sh-1 and Tu-124Sh-2 navigator trainer aircraft. Some 110 civil and 55 military examples were built by the time production ended with the majority serving Aeroflot. Export sales were weak since most potential customers awaited the improved Tu-134, but VIP transports were operated by the Indian Air Force. Other Tu-124s found their way into the militaries of Iraq and China.
