Landmarks in the History of Helicopters (Part 2 of 2)

In 1907 Paul Cornu became the very first to pilot a helicopter wherein he managed to lift off the ground for a mere couple of seconds. However, this design was not successful. Over next few years many new designs were experimented with to create enough lift and stability for the machine to stay in flight in a controlled manner.  It was in 1924, after many attempts by other men, French inventor, Etienne Oehmichen built and flew a helicopter the distance of one kilometer making it one of the great achievements of the era.

The period from 1924 to 1933 was marked by small improvements in helicopter design and performance, but did not witness the development of successful or practical designs.  However, the introduction of the Autogiro by Juan de la Cierva was a critical breakthrough that presented helicopter designers. Its rotor system incorporated numerous innovations necessary for practical helicopter rotor systems.

Autogiro and Focke-Wulf Fw 61

By 1936 many of the problems had solutions and with the introduction of the German Focke-Wulf Fw 61, the first practical helicopter was a reality. By this era the helicopter started to resemble the modern day helicopter. The German Focke-Wolfe Fw 61 was capable of flying up to 143 miles at 11,240 feet with a maximum speed of 75 mph.

Sikorsky's VS-300

In 1939 Sikorsky’s VS-300 one of the first practical helicopter and the first successful helicopter in the world to perfect the now familiar single main rotor and tail rotor design was built. The development of the VS-300 established the concepts and principles that were utilized in the design of the VS-316 (R-4), the world’s first production helicopter. Thus began the world’s helicopter industry.

This started helicopter flight in earnest. Later many companies like Sikorsky, Bell, and MIL would further design and develop helicopters that would become the basis for the modern day helicopters, evolving into the very versatile machine that they are today.
