The S-duct also finds use on combat aircraft, where it has the important advantage of blocking the front of the jet engine from radar. In international aviation regulations the triple engine layout is also considered inherently safer for the increased redundancy and this allows the use of certain airfields at high elevation only for aircraft with more than two engines. 1000s of Unique Dollhouse Miniatures Curated by Mini Lovers Like You. Since modern jet engines have more power and reliability than those of the 1970s and can safely power the aircraft with only two engines, the trijet design is no longer used for large commercial airliners but is used on the latest Dassault Falcon 7X and Falcon 8X business jets in order to provide significantly more total thrust while enabling the continued use of smaller engines in the 15-30kN class that all Falcons have historically been designed with.

The S-shaped duct is a complicated and costly design. The research undertaken during the design of the L-1011 indicated that losses of using an S-duct were more than compensated for by the above savings. The S-duct design also reduced the total empty aircraft weight. On the Lockheed L-1011 TriStar, engineers were able to maintain engine performance comparable with straight-through designs by limiting the curve of the S-duct to less than a quarter of the radius of the engine intake diameter. Ĭompared to the straight-through design on the DC-10 and MD-11, the S-duct allows a shorter fin and a rudder closer to the longitudinal axis. The straight-through layout also increases total aircraft aerodynamic drag by 2–4%. ![]() The straight-through layout leaves the engine high above the ground, making access difficult. Only the McDonnell Douglas DC-10 and MD-11 trijets' designers chose not to use the S-duct and go with a "straight-through" layout. Most trijet designs opted for the S-duct layout. The S-duct was easier to service than alternative trijet designs. ![]() The S-duct was invented as a solution for positioning the central engine on trijets. Currently, the Dassault Falcon 8X and Dassault Falcon 900 business jets are the only aircraft in production that use the S-duct design. The shape of the S-duct is distinctive and easily recognized, and was used in several aircraft, beginning in 1962 with the Hawker Siddeley Trident. The S-duct is located in the tail, or empennage, of the aircraft. In this configuration, the intake is in the upper rear center of the aircraft, above or below the stabilizer, while the exhaust and engine is at the rear of the aircraft. An S-duct (or serpentine inlet) is a type of jet engine intake duct used in several types of trijet aircraft. ![]()
