IAR 93
The Avioane Craiova IAR-93 Vultur (''Eagle'') is a twinjet, subsonic, close support, ground attack and tactical reconnaissance aircraft with secondary capability as low level interceptor. Built as single-seat main attack version or combat capable two-seat version for advanced flying and weapon training, it was developed as a joint Yugoslav-Romanian project in the 1970s for the air forces of both nations. The Romanian aircraft were built by I.R.Av. Craiova as IAR-93, and its Yugoslav counterpart by Soko as the Soko J-22 Orao. For Romania, the IAR-93 was intended to replace MiG-15s and MiG-17s in the fighter-bomber role. Development On May 20, 1971, Romania and Yugoslavia signed the governmental agreements for the YuRom R&D programme. The program managers were Dipl. Dr. Engineer Teodor Zamfirescu for the Romanian party and Colonel Vidoje Knežević for the Yugoslav party. The requirements called for a light subsonic aircraft for ground attack and tactical reconnaissance missions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Attack Aircraft
An attack aircraft, strike aircraft, or attack bomber is a tactical military aircraft that has a primary role of carrying out airstrikes with greater precision than bombers, and is prepared to encounter strong low-level air defenses while pressing the attack.Mortensen 1987, pp. 24–25. This class of aircraft is designed mostly for close air support and naval air-to-surface missions, overlapping the tactical bomber mission. Designs dedicated to non-naval roles are often known as ground-attack aircraft.Gunston 2009, p. 73. Fighter aircraft often carry out the attack role, although they would not be considered attack aircraft ''per se'', although fighter-bomber conversions of those same aircraft would be considered part of the class. Strike fighters, which have effectively replaced the fighter-bomber and light bomber concepts, also differ little from the broad concept of an attack aircraft. The dedicated attack aircraft as a separate class existed primarily during and after Wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reconnaissance
In military operations, reconnaissance or scouting is the exploration of an area by military forces to obtain information about enemy forces, terrain, and other activities. Examples of reconnaissance include patrolling by troops (skirmishers, long-range reconnaissance patrol, U.S. Army Rangers, cavalry scouts, or military intelligence specialists), ships or submarines, crewed or uncrewed reconnaissance aircraft, satellites, or by setting up observation posts. Espionage is usually considered to be different from reconnaissance, as it is performed by non-uniformed personnel operating behind enemy lines. Often called recce (British, Canadian and Australian English) or recon (American English), the word for this activity has at its root the associated verb ''reconnoitre'' or ''reconnoiter''. Etymology The word from the Middle French ''reconoissance''. Overview Reconnaissance conducted by ground forces includes special reconnaissance, armored reconnaissance, amp ...

Liberation From Fascist Occupation Day
Liberation Day, officially known as the Liberation from Fascist Occupation Day ( ro, Ziua eliberării de ocupația fascistă) was observed on 23 August in Communist Romania to celebrate the 1944 Romanian coup d'état, the event that caused Romania to leave the Axis in World War II and marked the beginning of the Soviet occupation of Romania (styled by the regime as "liberation"). It coincides with the European Day of Remembrance for Victims of Stalinism and Nazism. History On 23 August 1944, King Michael I of Romania, alongside politicians from allied opposition parties (the Romanian Communist Party, the Social Democratic Party, the National Liberal Party, and the National Peasants' Party) led a coup against Romanian Conducător, Marshal Ion Antonescu, and his fascist government. The successful coup, now known as King Michael's Coup, was organized in part due to the Romanian governments alignment with Nazi Germany and the Axis Powers. The day after the coup, the Army Group Dumi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerobatics
Aerobatics is the practice of flying maneuvers involving aircraft attitudes that are not used in conventional passenger-carrying flights. The term is a portmanteau of "aerial" and "acrobatics". Aerobatics are performed in aeroplanes and gliders for training, recreation, entertainment, and sport. Additionally, some helicopters, such as the MBB Bo 105, are capable of limited aerobatic manoeuvres. An example of a fully aerobatic helicopter, capable of performing loops and rolls, is the Westland Lynx. Most aerobatic manoeuvres involve rotation of the aircraft about its longitudinal (roll) axis or lateral (pitch) axis. Other maneuvers, such as a spin, displace the aircraft about its vertical (yaw) axis. Manoeuvres are often combined to form a complete aerobatic sequence for entertainment or competition. Aerobatic flying requires a broader set of piloting skills and exposes the aircraft to greater structural stress than for normal flight. In some countries, the pilot must wear a ...

Zero-zero Ejection Seat
In aircraft, an ejection seat or ejector seat is a system designed to rescue the pilot or other crew of an aircraft (usually military) in an emergency. In most designs, the seat is propelled out of the aircraft by an explosive charge or rocket motor, carrying the pilot with it. The concept of an ejectable escape crew capsule has also been tried. Once clear of the aircraft, the ejection seat deploys a parachute. Ejection seats are common on certain types of military aircraft. History A bungee-assisted escape from an aircraft took place in 1910. In 1916, Everard Calthrop, an early inventor of parachutes, patented an ejector seat using compressed air. The modern layout for an ejection seat was first introduced by Romanian inventor Anastase Dragomir in the late 1920s. The design featured a ''parachuted cell'' (a dischargeable chair from an aircraft or other vehicle). It was successfully tested on 25 August 1929 at the Paris-Orly Airport near Paris and in October 1929 at Băne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wing Flutter
Aeroelasticity is the branch of physics and engineering studying the interactions between the inertial, elastic, and aerodynamic forces occurring while an elastic body is exposed to a fluid flow. The study of aeroelasticity may be broadly classified into two fields: ''static aeroelasticity'' dealing with the static or steady state response of an elastic body to a fluid flow; and ''dynamic aeroelasticity'' dealing with the body's dynamic (typically vibrational) response. Aircraft are prone to aeroelastic effects because they need to be lightweight and withstand large aerodynamic loads. Aircraft are designed to avoid the following aeroelastic problems: # divergence where the aerodynamic forces increase the angle of attack of a wing which further increases the force; # control reversal where control activation produces an opposite aerodynamic moment that reduces, or in extreme cases, reverses the control effectiveness; and # flutter which is the uncontained vibration that can lead ...

Batajnica Air Base
The Colonel-pilot Milenko Pavlović Air Base ( sr, Војни аеродром пуковник-пилот Миленко Павловић, Vojni aerodrom pukovnik-pilot Milenko Pavlović), commonly known as Batajnica Air Base ( sr, Војни аеродром Батајница, Vojni aerodrom Batajnica) is the main military air base of Serbia. It is located between Batajnica and Nova Pazova, about 25 km northwest from the center of Belgrade, Serbia. It is the only airport in Serbia with two runways. History Construction of the airbase started in 1947 and was completed in 1951, when the airbase was officially opened with one grass and two asphalted runways. The purpose of the airbase is to protect the capital Belgrade from aircraft attacks. It was known as 177th Air Base until the 2006 reorganization and was home of 204th Fighter-Aviation regiment, 138th Transport-Aviation Regiment and other units of Yugoslav Air Force.

Bacău
Bacău ( , , ; hu, Bákó; la, Bacovia) is the main city in Bacău County, Romania. At the 2016 national estimation it had a population of 196,883, making it the 12th largest city in Romania. The city is situated in the historical region of Moldavia, at the foothills of the Carpathian Mountains, and on the Bistrița River (which meets the Siret River about to the south of Bacău). The Ghimeș Pass links Bacău to the region of Transylvania. Etymology The town's name, which features in Old Church Slavonic documents as ''Bako'', ''Bakova'' or ''Bakovia'', comes most probably from a personal name. Men bearing the name Bakó or Bako are documented in medieval TransylvaniaRădvan 2010, p. 456. and in 15th-century Bulgaria, but according to Victor Spinei the name itself is of Turkicmost probably of Cuman or Pechenegorigin. Nicolae Iorga believes that the city's name is of Hungarian origin (as Adjud and Sascut). Another theory suggests that the town's name has a Slavic origin, ...

Afterburner
An afterburner (or reheat in British English) is an additional combustion component used on some jet engines, mostly those on military supersonic aircraft. Its purpose is to increase thrust, usually for supersonic flight, takeoff, and combat. The afterburning process injects additional fuel into a combustor in the jet pipe behind (''i.e.'', "after") the turbine, "reheating" the exhaust gas. Afterburning significantly increases thrust as an alternative to using a bigger engine with its attendant weight penalty, but at the cost of increased fuel consumption (decreased fuel efficiency) which limits its use to short periods. This aircraft application of "reheat" contrasts with the meaning and implementation of "reheat" applicable to gas turbines driving electrical generators and which reduces fuel consumption. Jet engines are referred to as operating ''wet'' when afterburning and ''dry'' when not. An engine producing maximum thrust wet is at ''maximum power,'' while an engine ...

Rolls-Royce Viper
The Armstrong Siddeley Viper is a British turbojet engine developed and produced by Armstrong Siddeley and then by its successor companies Bristol Siddeley and Rolls-Royce Limited. It entered service in 1953 and remained in use with the Royal Air Force, powering its Dominie T1 navigation training aircraft until January 2011. Design and development The design originally featured a seven-stage compressor based on their Adder engine — the Viper is in effect a large-scale Adder. Like the similar J85 built in United States, the Viper was originally developed as an expendable engine for production versions of the Jindivik target drone. Like the J85, the limited-life components and total-loss oil systems were replaced with standard systems for use in crewed aircraft. Because it was initially developed as an expendable engine, the Viper was subject to many recurring maintenance issues. This led to the development of the first Power by the Hour program in which operators woul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
