S-40

The Sikorsky aircraft dynasty represents one of the most important and innovative chapters in the history of civil and commercial aviation. Built on advanced aerodynamic research and bold engineering, the company expressed the technological excellence of its home country through touring, transport, regional, and long-range passenger aircraft. The specific model Sikorsky S-40 made its maiden flight in 1931.

Designed to meet the growing operational requirements of commercial aviation and passenger or mail routes, this aircraft met strict criteria for stability, control reliability, and efficiency.

The various versions produced served key civil roles, solidifying the brand's reputation as a pioneer in global markets.

From a technical standpoint, the Sikorsky S-40 stands out for a solid and ingenious design, optimized to maximize passenger safety and comfort. The airframe implements refined aerodynamic solutions for its time.

Thrust is provided by 4 × Pratt & Whitney HornetB, proven and efficient powerplants. With a range of 1450 km, the aircraft features a cabin capable of accommodating up to 38 passengers or the operational load in a comfortable and ergonomic environment.

Flight aerodynamic behavior was characterized by exceptional stability and smoothness in the controls, highly valued by both commercial pilots and passengers.
