Delivering almost 22% more thrust with 40% fewer parts than its F100 predecessor, the F119 allows the F-22 to achieve supercruise speeds of up to Mach 1.8. [ 1 ] [ 2 ] The F119's nozzles incorporate thrust vectoring that enable them to direct the engine thrust ±20° in the pitch axis to give the F-22 enhanced maneuverability.
The Lockheed Martin/Boeing F-22 Raptor is an American twin-engine, all-weather, supersonic stealth fighter aircraft.As a product of the United States Air Force's Advanced Tactical Fighter (ATF) program, the aircraft was designed as an air superiority fighter, but also incorporates ground attack, electronic warfare, and signals intelligence capabilities.
An F-22 Raptor assigned to the 411th Flight Test Squadron flies over Edwards Air Force Base, California, in 2018. The squadron successfully tested the F-22 flying on a 50/50 fuel blend of conventional petroleum-based JP-8 and biofuel derived from camelina, a weed-like plant not used for food, in March 2011. The overall test objective was to ...
As of December 2020, the only combat-ready stealth aircraft in service are the Northrop Grumman B-2 Spirit (1997), the Lockheed Martin F-22 Raptor (2005), the Lockheed Martin F-35 Lightning II (2015), [15] [16] the Chengdu J-20 (2017), [17] and the Sukhoi Su-57 (2020), [18] with a number of other countries developing their own designs. There ...
An order from the engineering department (to be followed by the production department or vendor) overriding/superseding a detail on the drawing, which gets superseded with revised information. Also called by various other names, such as engineering change order (ECO), engineering change notice (ECN), drawing change notice (DCN), and so on.
The classic reproduction methods involved blue and white appearances (whether white-on-blue or blue-on-white), which is why engineering drawings were long called, and even today are still often called, "blueprints" or "bluelines", even though those terms are anachronistic from a literal perspective, since most copies of engineering drawings ...
Engineering can be a very broad term. It stems from the Latin ingenerare, meaning "to create". [6] Because this could apply to everything that humans create, it is given a narrower definition in the context of technical drawing. Engineering drawings generally deal with mechanical engineered items, such as manufactured parts and equipment.
The Lockheed Martin FB-22 was a proposed supersonic stealth bomber aircraft for the United States Air Force, derived from the F-22 Raptor air superiority fighter. Lockheed Martin proposed its design in the early 2000s with support from certain Air Force leaders as an interim "regional bomber" to complement the aging U.S. strategic bomber fleet, whose replacement was planned to enter service ...
