Schedules would be reduced, loads increased, and the use of fuel for aviation cut by 15 percent. Then, as now, we faced a crisis over energy. Nixon’s speech followed the OPEC oil shock, but.   WASHINGTON (AFNS) -- Aerodynamics testing on the KC Stratotanker confirmed vertically mounted wiper blades reduce aircraft drag by approximately 1% during cruise conditions, potentially saving the Air Force $7 million annually in associated fuel costs. Across the KC fleet, blades are positioned horizontally on the windshield as part of the aircraft’s original s design. "(Aviation fuel efficiency) is not a new AMC initiative, but through the use of new technology, the introduction of improved software and changes in procedures we're able to continually refine the processes that support the flying mission," said Royal Air Force Wing Commander Martin Walsh, deputy chief of the AMC Standardization and Evaluation.   Fuel costs comprise a major portion of air transport operating costs. Thus, energy efficiency is an essential design goal for future transport aircraft. Advanced composite structures, advanced wing geometries, and active control systems all Cited by: 2.

The energy efficiency in transport is the useful travelled distance, of passengers, goods or any type of load; divided by the total energy put into the transport propulsion means. The energy input might be rendered in several different types depending on the type of propulsion, and normally such energy is presented in liquid fuels, electrical energy or food energy.   Aircraft Airframe Fuel Systems Market by Aircraft Type (Commercial Aircraft, Military Aircraft, and UAV), by Engine Type (Jet Engine, Turboprop Engine, Helicopter Engine, and UAV Engine), by Component Type (Piping, Inerting Systems, Fuel Pumps, Fuel Valves, Fuel Gauging and Management System, Fuel Tanks, and Others), by Technology Type (Fuel Injection, Pump Feed Technology, and /5(12).   Pratt & Whitney says its new engines—which use an internal gearbox to slow down the speed of the fan—could save 20 percent on fuel consumption compared to .   Tow-steered composites can reduce the structural weight of an aircraft by 10 percent while reducing fuel burn by percent. NASA is building a prototype of .

Green Aviation Reduction of Environmental Impact Through Aircraft Technology and Alternative Fuels SAVE 20%. Improvement of aeropropulsion fuel efficiency through engine design. Airframe Design for Silent Fuel-Efficient Aircraft Article (PDF Available) in Journal of Aircraft 47(3) May with Reads How we measure 'reads'.   The new specification for the octane unleaded fuel is exactly the same as D—the specification for today’s leaded avgas—sans lead. This acceptance of a standard gives magneto-replacement manufacturers a standard to test against and is an important cornerstone for alternative ignition system development. This report updates a study that analyzed the sales- and activity-weighted fuel efficiency improvement of commercial jet aircraft from to It improves on that work in several significant ways, updating with new aircraft types and data for to deliveries and using refined metrics for measurement, including the efficiency metric value that the.
