Sikorsky H-5: One Seriously Ugly Helicopter

The article "Sikorsky H-5: One Seriously Ugly Helicopter" by Will Dabbs, MD, delves into the history and significance of the Sikorsky H-5 helicopter, an early model utilized during the Korean War. Historically designated as the R-5, the helicopter was colloquially known as the "Flying Washing Machine" due to its primitive construction and tough handling. Despite its unappealing appearance, the H-5 became instrumental in military operations, notably in medevac missions, thus earning a distinguished place in aviation history.

The article explains that although aesthetically unpleasing, the H-5 was a technically advanced aircraft for its time. It featured a 450-horsepower gasoline-powered Wasp Junior radial engine, an enclosed cockpit, and an aluminum airframe which represented an evolution from its predecessor, the R-4. This advancement allowed the H-5 to perform critical tasks such as rescuing injured soldiers from rugged terrains during the Korean War. The helicopter's cramped space and challenging flight requirements, including the need to manage its center of gravity carefully, didn't deter its success in various missions.

Moreover, the Sikorsky H-5 was the first commercial helicopter under the designation S-51 and played a role in the US Navy's Antarctic Development Program. Its use in commercial operations began in the late 1940s, operating in mail and passenger delivery. Despite its many limitations, the H-5's contribution to aviation, especially in medical evacuations and harsh environment operations, paved the way for future helicopter designs.
