The Northrop Grumman E-2 Hawkeye is an American all-weather, carrier-capable tactical airborne early warning (AEW) aircraft. This twin-turboprop aircraft was designed and developed during the late 1950s and early 1960s by the Grumman Aircraft Company for the United States Navy as a replacement for the earlier, piston-engined E-1 Tracer, which was rapidly becoming obsolete.
The E175-E2 exceeds this limit by 5,400 kg (12,000 lb), due to its heavier geared turbofan engines. [65] [66] The E175-E2 prototype first flew on 12 December 2019 from São José dos Campos and flew for 2 hours and 18 minutes, starting a test and certification campaign that was expected to take 24 months and involve two additional aircraft.

Typically, it is written in the form x/y, where x is the percentage of weight in the front, and y is the percentage in the back. In a vehicle which relies on gravity in some way, weight distribution directly affects a variety of vehicle characteristics, including handling , acceleration , traction , and component life.
The less you say, the more weight each word carries. In a minimalist design, a user might just state the one or a handful of things they wish to emphasize. Or simply provide links to elsewhere, relying on subpages to elaborate—this may make a crisp and clean first impression. One such design is the "hub" style userpage: like the one by AxG.
The SCREWTOPS returned home to Norfolk, VA on 27 March 2002 and were awarded the Battle 'E', the AKERS award for being the best E-2 Squadron and Naval Unit Commendations. In 2002, the SCREWTOPS operated locally out of Norfolk, VA and for a period of 4 months split the squadron to operate out of 2 Naval Air Stations, Norfolk and Oceana.
The EMD F-units followed the basic B-B truck design of the TA model, but with a V-16 EMD 567 prime mover generating 1350 hp as introduced in 1939. E-units standardized the two engine configuration for passenger locomotives to maximize power and, while the less-reliable Winton Diesel prime movers were in use, faced a less severe loss of power ...
Kit-of-parts philosophy goes hand in hand with advanced manufacturing, automation, and computer and information technologies. Handling multiple identical components as instances of a master element is an efficient use of the computer in the planning stage, and use of standard components can take advantage of mass-production and mass ...
The original designs were in the form of a fixed slot near the leading edge of the wing, a design that was used on a number of STOL aircraft. During World War II, German aircraft commonly fitted a more advanced version of the slat that reduced drag by being pushed back flush against the leading edge of the wing by air pressure , popping out ...
