EcoDemonstrator
The ecoDemonstrator Program is a Boeing flight test research program, which has used a series of specially modified aircraft to develop and test aviation technologies designed to improve fuel economy and reduce the noise and ecological footprint of airliners. Starting in 2012, several aircraft have tested a total of over 250 technologies as of 2024; half remain in further development, but nearly a third have been implemented commercially, such as iPad apps for pilot real-time information to reduce fuel use and emissions; custom approach paths to reduce community noise; and cameras for ground navigation and collision avoidance. Boeing's named airliner technology programs started in 2001 with the Quiet Technology Demonstrator, and have continued, through the ecoDemonstrator, to the ecoDemonstrator Explorer program announced in 2023. Quiet Technology Demonstrator program The ecoDemonstrator program followed the joint Rolls-Royce and Boeing Quiet Technology Demonstrator (QTD) ...

Fuel Economy In Aircraft
The fuel economy in aircraft is the measure of the energy efficiency in transport, transport energy efficiency of aircraft. Fuel efficiency is increased with better aerodynamics and by reducing weight, and with improved engine brake-specific fuel consumption and propulsive efficiency or thrust-specific fuel consumption. Endurance (aeronautics), Endurance and Range (aeronautics), range can be maximized with the optimum airspeed, and economy is better at optimum altitudes, usually higher. An airline efficiency depends on its fleet fuel burn, airline seating, seating density, air cargo and passenger load factor, while operational procedures like aircraft maintenance, maintenance and Airway (aviation), routing can save fuel. Average fuel burn of new aircraft fell 45% from 1968 to 2014, a compounded annual reduction 1.3% with a variable reduction rate. In 2018, CO₂ emissions totalled 747 million tonnes for passenger transport, for 8.5 trillion revenue passenger kilometres (RPK), ...

General Electric GE90
The General Electric GE90 is a family of High-bypass turbofan engine, high-bypass turbofan aircraft engines built by GE Aerospace for the Boeing 777, with thrust ratings from . It entered service with British Airways in November 1995. It is one of three engines for the 777-200 and -200ER, and the exclusive engine of the -200LR, -300ER, and 777F. It was the largest jet engine, until being surpassed in January 2020 by its successor, the General Electric GE9X, GE9X, which has a larger fan diameter by . However, the GE90-115B, the most recent variant of the GE90, is rated for a higher thrust (115,000 lbs) than the GE9X. Background In the early 1980s, GE began to develop an unducted fan (UDF) engine, which was thought to be a more fuel-efficient option to propel short-haul airliners, a compelling proposition after the 1979 oil crisis. NASA gave GE a grant in February 1984 to continue its research, eventually building the experimental General Electric GE36, GE36. One of the major inn ...

CFM International LEAP
The CFM International LEAP ("Leading Edge Aviation Propulsion") is a high-bypass turbofan engine produced by CFM International, a 50–50 joint venture between the American GE Aerospace and the French Safran Aircraft Engines. As the successor to the widely used CFM56, the LEAP competes directly with the Pratt & Whitney PW1000G to power narrow-body aircraft. Design The LEAP incorporates several design features intended to improve fuel efficiency and reduce emissions compared to the CFM56. Its architecture includes a scaled-down version of the low-pressure turbine used on the General Electric GEnx engine. The fan blades are made of composite materials via a resin transfer molding process and are designed to untwist under load to maintain aerodynamic efficiency. Although capable of operating at higher pressures than the CFM56, the LEAP engine is typically operated at lower pressures to improve durability and service life. It utilizes a higher proportion of composite material ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Grant County International Airport
Grant County International Airport is a public use airport located northwest of the central business district of Moses Lake in Grant County, Washington, United States. Formerly a military facility, the airport is owned by the Port of Moses Lake, and its runway is the 17th longest in the U.S. According to Federal Aviation Administration records, the airport had 1,369 passenger boardings (enplanements) in calendar year 2008, 2,920 enplanements in 2009, and 1,442 in 2010. It is included in the National Plan of Integrated Airport Systems for 2011–2015, which categorized it as a ''general aviation'' airport.

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for taxiing, takeoff or landing. For aircraft, it is generally needed for all three of these. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or Seaplane, floats needed to operate from snow/ice/water and skids for vertical operation on land. Retractable undercarriages fold away during flight, which reduces drag (physics), drag, allowing for faster airspeeds. Landing gear must be strong enough to support the aircraft and its design affects the weight, balance and performance. It often comprises three wheels, or wheel-sets, giving a tripod effect.

Toboggan
A toboggan is a simple sled used in snowy winter recreation. It is also a traditional form of cargo transport used by the Innu, Cree and Ojibwe of North America, sometimes part of a dog train. It is used on snow to carry one or more people (often children) down a hill or other slope for recreation, or as a rescue sled. Designs vary from simple, traditional models to modern engineered composites. A toboggan differs from most sleds or sleighs in that it has no runners or skis (or only low ones) on the underside. The bottom of a toboggan rides directly on the snow. Some parks include designated toboggan hills where ordinary sleds are not allowed and which may include toboggan runs similar to bobsleigh courses. Toboggans can vary depending on the climate and geographical region. Such examples are Tangalooma (Australia) where toboggans are made from Masonite boards and used for travelling down steep sand dunes at speeds up to . Etymology The term toboggan likely comes from an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
