SIKORSKY S-52 HO5S
Title: Sikorsky S-52 HO5S
The Sikorsky S-52 was a utility helicopter which first flew in 1947 and was the first US helicopter to use all-metal blades. It set several speed and altitude records in 1948 and in 1949 was the first helicopter to complete a loop.
93 examples were built, primarily for military users, and the airframe formed the basis for Sikorsky’s unsuccessful contender for the contract which produced the Bell UH-1. In the early 1990’s a kit version for amateur construction was developed as the Vertical Hummingbird.
