Kaman K-125B N60377 - NX60377
Kaman K-125B N60377 / NX60377 (msn 1). The first helicopter designed and built by (Charles H) Kaman Aircraft Corp, Bradley Field, Windsor Locks CT. as the Kaman K-125, powered by a 4-cylinder horizontally-opposed Lycoming O-290. Fitted with a more powerful 6-cylinder Lycoming engine (150hp O-350 or 175 hp O435), the aircraft became the K-125B and was progressively transformed to have a smooth-skinned plywood fuselage pod. Two more similar helicopters were produced with more powerful piston engines, (K-190 and K-225), one of which was fitted with a Boeing 502 (YT50) turbo-shaft engine to become the first gas-turbine powered helicopter in the world. Date: 1947

EDITORS COMMENTS
This historic photograph captures the Kaman K-125B N60377 / NX60377 (MSN 1), the first helicopter designed and built by Charles H. Kaman Aircraft Corp at Bradley Field in Windsor Locks, Connecticut. Initially powered by a 4-cylinder horizontally-opposed Lycoming O-290 engine, the helicopter was later upgraded with a more powerful 6-cylinder Lycoming engine, either a 150hp O-350 or 175 hp O435. With these improvements, the helicopter was renamed K-125B and featured a smooth-skinned plywood fuselage pod. Two additional helicopters, the K-190 and K-225, were produced with even more powerful piston engines. One of these helicopters, the K-225, was fitted with a Boeing 502 (YT50) turbo-shaft engine, making it the world's first gas-turbine powered helicopter. This groundbreaking achievement in aviation history took place in 1947. The Kaman K-125B N60377 / NX60377 (MSN 1) is an important milestone in the development of helicopter technology. Its innovative design and engineering paved the way for future advancements in rotary-wing aircraft. This photograph is a testament to the pioneering spirit and ingenuity of the Kaman Aircraft Corp and the aviation industry as a whole.
