Igor Ivanovich Sikorsky (25th May 1889 – 26th October 1972), was a Russian American aviation pioneer in both helicopters and fixed-wing aircraft. He designed and flew the world’s first multi-engine fixed-wing aircraft, the Russky Vityaz in 1913, and the first airliner, Ilya Muromets, in 1914.
After immigrating to the United States in 1919, Sikorsky founded the Sikorsky Aircraft Corporation in 1923, and developed the first of Pan American Airways’ ocean-conquering flying boats in the 1930s.
In 1939 Sikorsky designed and flew the Vought-Sikorsky VS-300, the first viable American helicopter, which pioneered the rotor configuration used by most helicopters today.Sikorsky modified the design into the Sikorsky R-4, which became the world’s first mass-produced helicopter in 1942.
Igor Sikorsky was born in Kiev, Russian Empire (present-day Ukraine), the youngest of five children. His father, Ivan Alexeevich Sikorsky, had a Russian and noble Polish (Polish: szlachta) family background. A professor of psychology, Ivan was the son and grandson of Russian Orthodox priests and held monarchist and Russian nationalist views. Igor Sikorsky was Russian Orthodox Christian. Following the Russian Revolution, Sikorsky became a White emigre and opposed Soviet rule.
Igor Sikorsky’s mother, Mariya Stefanovna Sikorskaya (née Temryuk-Cherkasova), was a physician who did not work professionally. She is sometimes called Zinaida Sikorsky. While homeschooling young Igor, she gave him a great love for art, especially in the life and work of Leonardo da Vinci, and the stories of Jules Verne. In 1900, at age 11, he accompanied his father to Germany and through conversations with his father, became interested in natural sciences. After returning home, Sikorsky began to experiment with model flying machines, and by age 12, he had made a small rubber band-powered helicopter.
Sikorsky began studying at the Saint Petersburg Imperial Russian Naval Academy, in 1903, at the age of 14. In 1906, he determined that his future lay in engineering, so he resigned from the Academy, despite his satisfactory standing, and left the Russian Empire to study in Paris. He returned to Russia in 1907, enrolling at the Mechanical College of the Kiev Polytechnic Institute. After the academic year, Sikorsky again accompanied his father to Germany in the summer of 1908, where he learned of the accomplishments of the Wright brothers’ Flyer and Ferdinand von Zeppelin’s dirigible. Sikorsky later said about this event: “Within twenty-four hours, I decided to change my life’s work. I would study aviation.”
With financial backing from his sister Olga, Sikorsky returned to Paris in 1909 to study aeronautics in the world-renowned Ecole des Techniques Aéronautiques et de Construction Automobile in Paris (ETACA, now École supérieure des techniques aéronautiques et de construction automobile (fr)) engineering school and to purchase aircraft parts.At the time, Paris was the center of the aviation world. Sikorsky met with aviation pioneers, to ask them questions about aircraft and flying. In May 1909, he returned to Russia and began designing his first helicopter, which he began testing in July 1909. Despite his progress in solving technical problems of control, Sikorsky realized that the aircraft would never fly. He finally disassembled the aircraft in October 1909, after he determined that he could learn nothing more from the design.
I had learned enough to recognize that with the existing state of the art, engines, materials, and – most of all – the shortage of money and lack of experience… I would not be able to produce a successful helicopter at that time.
Sikorsky’s first aircraft of his own design, the S-1 used an 15 hp Anzani engine, that could not lift the aircraft. His second 25 hp Anzani model S-2 flew on 16th June 1910 at a height of a few feet. Later, Sikorsky built the two-seat S-5, his first design not based on other European aircraft. Flying this original aircraft, Sikorsky earned his pilot license; Fédération Aéronautique Internationale (FAI) license No. 64 issued by the Imperial Aero Club of Russia in 1911. During a demonstration of the S-5, the engine quit and Sikorsky was forced to make a crash landing to avoid a wall. It was discovered that a mosquito in the gasoline had been drawn into the carburetor, starving the engine of fuel. The close call convinced Sikorsky of the need for an aircraft that could continue flying if it lost an engine. His next aircraft, the S-6 held three passengers and was selected as the winner of the Moscow aircraft exhibition held by the Russian Army in February 1912.
In early 1912, Igor Sikorsky became Chief Engineer of the aircraft division for the Russian Baltic Railroad Car Works (Russko-Baltiisky Vagonny Zavod or R-BVZ)in Saint Petersburg.His work at R-BVZ included the construction of the first four-engine aircraft, the S-21 Russky Vityaz, which he initially called Le Grand when fitted with just two engines, then as the Bolshoi Baltisky (The Great Baltic) when fitted with four engines for the first time, each wing panel’s pair of powerplants in a “push-pull” tandem configuration previous to the four tractor-engined Russki Vityaz. He also served as the test pilot for its first flight on 13rd May 1913. In recognition for his accomplishment, he was awarded an honorary degree in engineering from Saint Petersburg Polytechnical Institute in 1914. Sikorsky took the experience from building the Russky Vityaz to develop the S-22 Ilya Muromets airliner. Due to outbreak of World War I, he redesigned it as the world’s first four-engined bomber, for which he was decorated with the Order of St. Vladimir.
After World War I, Igor Sikorsky briefly became an engineer for the French forces in Russia, during the Russian Civil War.Seeing little opportunity for himself as an aircraft designer in war-torn Europe, and particularly Russia, ravaged by the October Revolution and Civil War, he immigrated to the United States, arriving in New York on March 30, 1919.
In the United States, Sikorsky first worked as a school teacher and a lecturer, while looking for an opportunity to work in the aviation industry. In 1932, he joined the faculty of the University of Rhode Island to form an Aeronautical Engineering program and remained with the University until 1948. He also lectured at the University of Bridgeport.
In 1923, Sikorsky formed the Sikorsky Manufacturing Company in Roosevelt, New York.He was helped by several former Russian military officers. Among Sikorsky’s chief supporters was composer Sergei Rachmaninoff, who introduced himself by writing a check for US$ 5,000 (approximately $ 61,000 in 2007 dollars). Although his prototype was damaged in its first test flight, Sikorsky persuaded his reluctant backers to invest another $ 2,500. With the additional funds, he produced the S-29, one of the first twin-engine aircraft in America, with a capacity for 14 passengers and a speed of 115 mph. The performance of the S-29, slow compared to military aircraft of 1918, proved to be a “make or break” moment for Sikorsky’s funding.
In 1928, Sikorsky became a naturalized citizen of the United States. The Sikorsky Manufacturing Company moved to Stratford, Connecticut in 1929. It became a part of the United Aircraft and Transport Corporation (now United Technologies Corporation) in July of that year. The company manufactured flying boats, such as the S-42 “Clipper”, used by Pan Am for transatlantic flights.
Meanwhile, Sikorsky also continued his earlier work on vertical flight while living in Nichols, Connecticut. On February 14, 1929, he filed an application to patent a “direct lift” amphibian aircraft which used compressed air to power a direct lift “propeller” and two smaller propellers for thrust. On 27th June 1931, Sikorsky filed for a patent for another “direct lift aircraft”, and was awarded patent #1,994,488 on 19th March 1935. His design plans eventually culminated in the first (tethered) flight of the Vought-Sikorsky VS-300 on 14th September 1939, with the first free flight occurring eight months later on 24th May 1940. Sikorsky’s success with the VS-300 led to the R-4, which became the world’s first mass-produced helicopter in 1942. Sikorsky’s final VS-300 rotor configuration, comprising a single main rotor and a single antitorque tail rotor, has proven to be one of the most popular helicopter configurations, being used in most helicopters produced today.
Igor Sikorsky was also on the Board of Directors for the Tolstoy Foundation Center in Valley Cottage, New York.
Sikorsky was married to Olga Fyodorovna Simkovitch in Russia. They were divorced and Olga remained in Russia with their daughter, Tania, as Sikorsky departed ahead of the October Revolution. In 1923, Sikorsky’s sisters immigrated to the United States, bringing six-year-old Tania with them. Sikorsky married Elisabeth Semion (1903–1995) in 1924, in New York. Sikorsky and Elisabeth had four sons; Sergei, Nikolai, Igor Jr. and George.
Sikorsky died at his home in Easton, Connecticut, on 26th October 1972, and is buried in Saint John the Baptist Russian Orthodox Cemetery located on Nichols Avenue in Stratford.
The Sikorsky Memorial Bridge, which carries the Merritt Parkway across the Housatonic River next to the Sikorsky corporate headquarters, is named for him. Sikorsky has been designated a Connecticut Aviation Pioneer by the Connecticut State Legislature. The Sikorsky Aircraft Corporation in Stratford, Connecticut, continues to the present day as one of the world’s leading helicopter manufacturers, and a nearby small airport has been named Sikorsky Memorial Airport.
Sikorsky was inducted into the National Inventors Hall of Fame and the Junior Achievement U.S. Business Hall of Fame in 1987.
In October 2011, one of the streets in Kiev was renamed after Sikorsky. The decision was made by the City Council at the request of the U.S. Embassy in Ukraine, which opened its new office in that street. The Sikorsky’s family house in the city’s historical center is preserved to this day but is in a neglected condition pending restoration.
In November 2012, one of the Russian supersonic heavy strategic bomber Tu-160, based at the Engels-2 Air Force Base, was named after Igor Sikorsky, that caused controversy among air base crew members. One of the officers said that Igor Sikorsky doesn’t deserve it because he laid the foundations of the U.S., rather than Russian aviation. However, the Long Range Aviation command officer said that Igor Sikorsky is not responsible for the activities of his military aircraft. In 2013, Flying magazine ranked Sikorsky number 12 on its list of the 51 Heroes of Aviation.
