Ilya Muromets (aircraft)
The Sikorsky ''Ilya Muromets'' (russian: Сикорский Илья Муромец) (Sikorsky S-22, S-23, S-24, S-25, S-26 and S-27) were a class of Russian pre-World War I large four-engine commercial airliners and military heavy bombers used during World War I by the Russian Empire. The aircraft series was named after Ilya Muromets, a hero from Slavic mythology.Lake 2002, p. 31. The series was based on the Sikorsky Russky Vityaz, Russky Vityaz or Le Grand, the world's first four-engined aircraft, designed by Igor Sikorsky. The Ilya Muromets aircraft as it appeared in 1913 was a revolutionary design, intended for commercial service with its spacious fuselage incorporating a passenger saloon and washroom on board. The Ilya Muromets was the world's first multi-engine aircraft in production and at least sixty were built.Sikorsky 1938, p. 96. During World War I, it became the first four-engine bomber to equip a dedicated strategic bombing unit.Massenkov et al. 1994, p. 23. This ...

Tractor Configuration
In aviation, the term tractor configuration refers to an aircraft constructed in the standard configuration with its engine mounted with the propeller in front of it so that the aircraft is "pulled" through the air. Oppositely, the pusher configuration places the airscrew behind and propels the aircraft forward. Through common usage, the word "propeller" has come to mean any airscrew, whether it actually propels or pulls the plane. In the early years of powered aviation both tractor and pusher designs were common. However, by the midpoint of the First World War, interest in pushers declined and the tractor configuration dominated. Today, propeller-driven aircraft are assumed to be tractors unless it is stated otherwise. Origins The first airplane to have a "tractor" configuration was the Goupy No.2 (first flight on 11 March 1909) designed by Mario Calderara and financed by Ambroise Goupy at the French firm Blériot Aéronautique. When it was constructed, it was the fast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tail Gunner
A tail gunner or rear gunner is a crewman on a military aircraft who functions as a gunner defending against enemy fighter or interceptor attacks from the rear, or "tail", of the plane. The tail gunner operates a flexible machine gun or autocannon emplacement in the tail end of the aircraft with an unobstructed view toward the rear of the aircraft. While the term ''tail gunner'' is usually associated with a crewman inside a gun turret, the first tail guns were operated from open apertures within the aircraft's fuselage, such as the Scarff ring mechanism used in the British Handley Page V/1500, which was introduced during latter months of the First World War. Increasingly capable tail gunner positions were developed during the interwar period and the Second World War, resulting in the emergence of the powered turret and fire control systems incorporating radar guidance. In particularly advanced tail gunner arrangements, the tail armament may be operated by remote control fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tsar Nicholas II
Nicholas II or Nikolai II Alexandrovich Romanov; spelled in pre-revolutionary script. ( 186817 July 1918), known in the Russian Orthodox Church as Saint Nicholas the Passion-Bearer,. was the last Emperor of Russia, King of Congress Poland and Grand Duke of Finland, ruling from 1 November 1894 until his abdication on 15 March 1917. During his reign, Nicholas gave support to the economic and political reforms promoted by his prime ministers, Sergei Witte and Pyotr Stolypin. He advocated modernization based on foreign loans and close ties with France, but resisted giving the new parliament (the Duma) major roles. Ultimately, progress was undermined by Nicholas's commitment to autocratic rule, strong aristocratic opposition and defeats sustained by the Russian military in the Russo-Japanese War and World War I. By March 1917, public support for Nicholas had collapsed and he was forced to abdicate the throne, thereby ending the Romanov dynasty's 304-year rule of Russia (161 ...

Altimeter
An altimeter or an altitude meter is an instrument used to measure the altitude of an object above a fixed level. The measurement of altitude is called altimetry, which is related to the term bathymetry, the measurement of depth under water. The most common unit for altimeter calibration worldwide is hectopascals (hPa), except for North America (other than Canada ) and Japan where inches of mercury (inHg) are used. To obtain an accurate altitude reading in either feet or meters, the local barometric pressure must be calibrated correctly using the barometric formula. History The scientific principles behind the altimeter were first written by Alexander Bryce (minister), Rev. Alexander Bryce a Scottish minister and astronomer in 1772 who realised that the principles of a barometer could be adjusted to measure height. Pressure altimeter Altitude can be determined based on the measurement of atmospheric pressure. The greater the altitude, the lower the pressure. When a barometer is s ...

Compass
A compass is a device that shows the cardinal directions used for navigation and geographic orientation. It commonly consists of a magnetized needle or other element, such as a compass card or compass rose, which can pivot to align itself with magnetic north. Other methods may be used, including gyroscopes, magnetometers, and GPS receivers. Compasses often show angles in degrees: north corresponds to 0°, and the angles increase clockwise, so east is 90°, south is 180°, and west is 270°. These numbers allow the compass to show azimuths or bearings which are commonly stated in degrees. If local variation between magnetic north and true north is known, then direction of magnetic north also gives direction of true north. Among the Four Great Inventions, the magnetic compass was first invented as a device for divination as early as the Chinese Han Dynasty (since c. 206 BC),Li Shu-hua, p. 176 and later adopted for navigation by the Song Dynasty Chinese during the 11th centur ...

Tachometer
A tachometer (revolution-counter, tach, rev-counter, RPM gauge) is an instrument measuring the rotation speed of a shaft or disk, as in a motor or other machine. The device usually displays the revolutions per minute (RPM) on a calibrated analogue dial, but digital displays are increasingly common. The word comes from Greek ''τάχος'' (''táchos'' "speed") and ''μέτρον'' (''métron'' "measure"). Essentially the words tachometer and speedometer have identical meaning: a device that measures speed. It is by arbitrary convention that in the automotive world one is used for engine revolutions and the other for vehicle speed. In formal engineering nomenclature, more precise terms are used to distinguish the two. History The first tachometer was described by an Donkin in a paper to the Royal Society of Arts in 1810 for which he was awarded the Gold medal of the society. This consisted of a bowl of mercury constructed in such a way that centrifugal force caused the level ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
