1957 Engined Gazelle Napier Piston Radial Replacing Sikorsky Turboshaft Westland Xl722 Aeronautics
EDITORS COMMENTS
In this photograph, the Sikorsky-built S-58, XL722, takes center stage, showcasing an intriguing transformation. This helicopter, manufactured by Sikorsky in 1957, underwent a significant modification by the renowned British aircraft company, Westland. The most notable change was the replacement of its original radial piston engine with a modern Napier Gazelle turboshaft engine. The Sikorsky S-58, also known as the Sikorsky Sea King, is a versatile twin-engine, twin-main rotor helicopter that was initially designed for the US military. Its robust design and impressive capabilities made it a popular choice for various applications, including search and rescue, military transport, and law enforcement. In the late 1950s, Westland, a leading British aircraft manufacturer, recognized the potential of the S-58 and sought to enhance its performance by integrating a more advanced powerplant. The Napier Gazelle turboshaft engine, a powerful and efficient aeronautical innovation, was the perfect choice. This upgrade not only increased the helicopter's power output but also improved its overall efficiency and reliability. The photograph captures the XL722 during this pivotal moment in its history, with the Napier Gazelle engine proudly installed. The date, June 1957, marks the beginning of a new chapter for this remarkable helicopter, as it embarked on a journey of continued innovation and excellence in the realm of aviation. This image is a testament to the relentless pursuit of progress in the aeronautical industry, as companies like Sikorsky and Westland collaborated to push the boundaries of helicopter technology. The Sikorsky-built S-58, XL722, with its Napier Gazelle turboshaft engine, stands as a symbol of ingenuity, adaptability, and the enduring spirit of aviation.
