    Lead Center: LaRC The challenge of energy-efficient flight has at its foundation aerodynamic efficiency, and at the foundation of aerodynamic efficiency is low drag. Drag can be broadly decomposed into four components: viscous or skin friction drag, lift-induced drag, wave or compressibility drag, and excrescence drag due to various protruding. for the aerodynamic model become clear. The normal flight envelope, where FFS aerodynamic models are well validated should be extended to areas with high angles of attack at low and high Mach numbers from takeoff to cruise speeds of - flight.

    The Next Generation Air Transportation System (NextGen) is an ongoing modernization project of the United States National Airspace System (NAS). The US Federal Aviation Administration (FAA) began work on NextGen improvements in and plans to have all major components in place by The goals of the modernization include using new technologies and procedures to increase the safety. environmental. This will allow air transport to grow in an environmentally sustainable manner, while continuing to ensure freedom to travel by air. 3. The democratization of air travel is one of the wonders of our age. Access to sustainable air transport must be guaranteed for future generations. 4. Rio+20 must set clear objectives and establish.

An extension of this analysis is shown in figure 9 in which the drag breakdown analysis is limited to only the ground transportation sector.

The data of figure 9 shown that ground transportation drag is 20% skin friction drag and 80% pressure drag. This. Impact of Advanced Aerodynamic Technology on Transportation Energy Consumption An assessment of the role of fluid dynamic resistance and/or aerodynamic drag and the relationship to energy use in the United States is by: “Aerodynamic Impact on Noise and Emissions”, Session IV of “Potential Impacts of Advanced Aerodynamic Technology on Air Transportation System Productivity”, NASA Technical Memorandum Author: Egbert Torenbeek.

ine the potential for advanced air transport technology, both passenger and cargo. The objectives of this study were to examine the economic, environmental, energy, soci-etal, and safety impacts of advances in the technology of high-speed aircraft, com-muter aircraft, and air cargo.

To bring the scope of the assessment within manageable. The air transportation system is changing and will continue to change. Over the long term, however, it will be difficult for the air transportation system to change rapidly enough to meet changing requirements related to capacity, environmental effects, consumer satisfaction, safety, and security, while meeting ongoing requirements for the economic viability of service providers.

In order to identify the exact sources of noises through noise source identification technology developed by JAXA which uses multiple microphones to identify the noise source, this study aims to improve the resolution of sound pressure distribution to which image processing methods were applied, and to develop technology for identifying aerodynamic phenomena which cause noise by simultaneously.

current air transportation systems is not a solution. There is a need for a revolutionary approach to both the air transportation operations as well as the development of large and small aircraft.

To revolutionize the operational efficiency of the air transportation system requires insertion of new technology such as anCited by: The air transportation system already expends considerable resources to deal with public concerns and government regulations related to the effects of aviation on local and regional air quality, climate change, and community noise.

Few researchers have performed aerodynamic studies on the vehicles in order to evaluate the impact of various flow parameters like velocity, surface area Author: Richard M Wood.

Engineers are closer to understanding, and therefore manipulating, invisible aerodynamic drag forces, that cause an estimated 50 per cent of transportation fuel to be lost before we can use it. Home» Advanced Aerodynamic Technologies for Improving Fuel Economy in Ground Vehicles Heavy vehicles lose a tremendous amount of energy from wind resistance, braking, and rolling resistance.

Such non-engine losses can account for about a 45% decrease in efficiency. Frederick O. Smetana is Professor Emeritus at North Carolina State University. Prior to his year academic career, he served as a flight test engineer for the Douglas Aircraft Co.
