S-92 design changes to meet customer requirements

In response to customer requests for additional cabin space and a larger main door, Sikorsky is increasing the S-92 cabin length by 16 inches (41 cm), reducing the height of the tail pylon and relocating the horizontal stabiliser.

The extension added to the forward part of the cabin will allow the installation of a 50-inch (1.27 m) wide door to improve hoisting capabilities and accommodate a Stokes litter during search and rescue operations.

Reducing the tail pylon by approximately 40 inches (one meter) will largely offset the additional weight from the cabin extension. This combination of changes will allow the S-92 to maintain current payload and range.

These design changes provide additional benefits. These include creating an improved fold configuration for shipboard use and increased bird-strike protection by relocating the tail rotor driveshaft and controls aft of the tail spar.

These changes will move the aircraft's centre of gravity forward and result in a flatter hover attitude that improves visibility for confined and shipboard landings and increases aft fuselage clearance from the ground on landing.

The third, fourth and fifth S-92 prototype and all subsequent production aircraft will incorporate the design changes. The changes will not have any impact on price.
