Type 1475 Radar
The Chengdu J-20 (), also known as Mighty Dragon (, NATO reporting name: Fagin), is a twin-engine all-weather stealth fighter developed by China's Chengdu Aircraft Corporation for the People's Liberation Army Air Force (PLAAF). The J-20 is designed as an air superiority fighter with precision strike capability. The aircraft has three notable variants: the initial production model, the revised airframe variant with new engines and thrust-vectoring control, and the aircraft-teaming capable twin-seat variant. Descending from the J-XX program of the 1990s, the aircraft made its maiden flight on 11 January 2011, and was officially revealed at the 2016 China International Aviation & Aerospace Exhibition. The aircraft entered service in March 2017 with the first J-20 combat unit formed in February 2018, making China the second country in the world to field an operational stealth aircraft. Development The J-20 emerged from the late-1990s J-XX program. In 2008, the PLAAF endorse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

WS-10
The Shenyang WS-10 (), codename Taihang, is a turbofan engine designed and built by the People's Republic of China. Chinese media reported 266 engines were manufactured from 2010 to 2012 for the J-11 program. Unofficial estimates placed production at more than 300 units by May 2015. Description The WS-10A is advertised as an engine with thrust. It has full authority digital engine control (FADEC). Development The WS-10 is reverse engineered from the CFM56 with the experience gained from the Woshan WS-6 turbofan project, which was abandoned at the start of the 1980s. The WS-10 project was reportedly started by Deng Xiaoping in 1986 to produce an engine comparable to the Saturn AL-31. The work was given to the Shenyang Aeroengine Research Institute (606 Institute) of the Aviation Industry Corporation of China (AVIC). Initial production models suffered quality issues from the early direct use of AL-31 control systems. Furthermore, Salyut refused to sell the control system s ...

Tactical Bombing
Tactical bombing is aerial bombing aimed at targets of immediate military value, such as combatants, military installations, or military equipment. This is in contrast to strategic bombing, or attacking enemy cities and factories to cripple future military production and enemy civilians' will to support the war effort, to debilitate the enemy's long-term capacity to wage war. The term "tactical bomber" only refers to a bomber aircraft designed specifically for the primary role of tactical bombing, even though many other types of aircraft ranging from strategic bombers to fighters, interceptors, and helicopters have been used in tactical bombing operations. Tactical bombing is employed for two primary assignments. Aircraft providing close air support attack targets in nearby proximity to friendly ground forces, acting in direct support of the ground operations (as a "flying artillery"). Air interdiction, by contrast, attacks tactical targets that are distant from or ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low Rate Initial Production
Low rate initial production (LRIP) is a term commonly used in military weapons projects and programs to designate the phase of initial, small-quantity production. The term is also applied in fields other than weapons production, most commonly in non-weapon military equipment programs. With LRIP, the prospective first buyer and operator (i.e., a country's defense authorities and the relevant military units) can thoroughly test the weapons system over some protracted amount of time in order to gain a reasonable degree of confidence as to whether the system actually performs to the agreed-upon requirements before contracts for mass production are signed. At the same time, manufacturers can use the LRIP as a production test phase in which they develop the assembly line models that would eventually be used in mass production. Therefore, the LRIP is commonly the first step in transitioning from highly customized, hand-built prototypes to the final mass-produced end product. In practic ...

Diverterless Supersonic Inlet
A diverterless supersonic inlet (DSI) is a type of jet engine air intake used by some modern combat aircraft to control air flow into their engines. It consists of a "bump" and a forward-swept inlet cowl, which work together to divert boundary layer airflow away from the aircraft's engine. This eliminates the need for a splitter plate, while compressing the air to slow it down from supersonic to subsonic speeds. The DSI can be used to replace conventional methods of controlling supersonic and boundary-layer airflow. DSIs can be used to replace the intake ramp and inlet cone, which are more complex, heavy and expensive. Technical background The fundamental design of a gas turbine engine is such that the air flow-rate entering its compressor is regulated by the amount of fuel burned in its combustor. For supersonic flight the air entering the inlet also has to be regulated to a similar amount by the design of the entrance of the inlet duct. The optimum design of the duct wil ...

Chengdu Aircraft Design Institute
AVIC Chengdu Aircraft Research and Design Institute (CADI; zh, s=成都飞机设计研究所, labels=no; historically the 611 Institute) is a design institute that works with the Chengdu Aircraft Industry Group for military aircraft. Built in 1970, it covers an area of 310,000 square meters. History In May 1970, the Shenyang design team for the J-9 moved to Chengdu; this was part of the " Third Line" program that moved defence industries to the interior to make them less vulnerable to foreign attack. The team was later renamed as the 611 Institute. The design work on the cancelled double-canard J-9 influenced later CADI designs. The Chengdu J-10 used the double-canard layout. The Chengdu J-20 also used canards.

Taxiing
Taxiing (rarely spelled taxying) is the movement of an aircraft on the ground, under its own power, in contrast to towing or pushback (aviation), pushback where the aircraft is moved by a tug. The aircraft usually moves on wheels, but the term also includes aircraft with skis or Buoyancy, floats (for water-based travel). An airplane uses taxiways to taxi from one place on an airport to another; for example, when moving from a hangar to the runway. The term "taxiing" is not used for the accelerating run along a runway prior to takeoff, or the decelerating run immediately after landing, which are called the takeoff roll and landing rollout, respectively; however, aircraft are considered to be taxiing when they leave the runway after landing to travel to a gate (airport), gate or remote stand for disembarkment. Etymology As early as 1909 aviation journalists envisioned aeroplanes to replace the taxicab in traffic-congested cities. Some aviators and some linguists report t ...
