Information: - World WarII (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the world's nationsincluding all of the great powerseventually forming two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. In a state of "total war", the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources. Marked by mass deaths of civilians, including the Holocaust (in which approximately 11 million people were killed) and the strategic bombing of industrial and population centres (in which approximately one million were killed, and which included the atomic bombings of Hiroshima and Nagasaki), it resulted in an estimated 50 million to 85 million fatalities. These made World WarII the deadliest conflict in human history. - The Sikorsky S - 16 ( named after its designer ) or RBVZ S - XVI ( named after its manufacturer ) was a Russian equi - span single - bay two - seat biplane designed by Igor Sikorsky in 1914 - 15 . Conceived in response to demand for an escort fighter for the Ilya Muromets bombers , it was noteworthy in that it was one of the first aircraft to possess synchronisation gear for its 7.7mm machine gun . The first S - XVI was completed on 6 February 1915 with an 80 hp engine instead of the intended 100 hp because of supply problems . On 17 December 1915 , the Russian government placed an order for 18 aircraft , these being delivered in early 1916 . - A fixed-wing aircraft is an aircraft, such as an aeroplane, which is capable of flight using wings that generate lift caused by the vehicle's forward airspeed and the shape of the wings. Fixed-wing aircraft are distinct from rotary-wing aircraft, in which the wings form a rotor mounted on a spinning shaft, and ornithopters, in which the wings flap in similar manner to a bird. - A bomber is a combat aircraft designed to attack ground and sea targets by dropping air-to-ground weaponry, firing torpedoes or deploying air-launched cruise missiles. - A fighter aircraft is a military aircraft designed primarily for air-to-air combat against other aircraft, as opposed to bombers and attack aircraft, whose main mission is to attack ground targets. The hallmarks of a fighter are its speed, maneuverability, and small size relative to other combat aircraft. - The escort fighter was a World War II concept for a fighter aircraft designed to escort bombers to and from their targets. An escort fighter needed range long enough to reach the target, loiter over it for the duration of the raid to defend the bombers, and return. - A helicopter is a type of rotorcraft in which lift and thrust are supplied by rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward, and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of VTOL (vertical takeoff and landing) aircraft cannot perform. - Igor Ivanovich Sikorsky ("Igor' Ivanovi Sikorskij" "Ihor Ivanovych Sikorskyi"; May 25, 1889 October 26, 1972), was a Russian-American aviation pioneer in both helicopters and fixed-wing aircraft. First success came with the S-2, the second fixedwing plane of his design and construction. His fifth airplane, the S-5, won him national recognition as well as F.A.I. license Number 64. His S-6-A received the highest award at the 1912 Moscow Aviation Exhibition. and in the fall of that year the aircraft won for its young designer, builder and pilot first prize in the military competition at Petrograd.
