The National Aeronautics and Space Administration (NASA) has made a commitment to deliver data to the International Civil Aviation Organization’s Committee on Aviation Environmental Protection (ICAO CAEP) defining community response to sounds from supersonic aircraft designed such that their sonic boom is replaced with a soft “thump” sound. The dataset will be a correlation of public perceptions of these sounds to the corresponding acoustic levels and will support efforts to develop international standards for permissible noise from supersonic overflight.

AbstractProton exchange membrane fuel cells (PEMFC) not only offer more efficient electrical energy conversion, relative to on-ground/backup turbines but generate by-products useful in aircraft such as heat for ice prevention, deoxygenated air for fire retardation and drinkable water for use on-board. Consequently, several projects (e.g. DLR-H2 Antares and RAPID2000) have successfully tested PEMFC-powered auxiliary unit (APU) for manned/unmanned aircraft. Despite the progress from flying PEMFC-powered small aircraft with 20 kW power output as high as 1 000 m at 100 km/h to 33 kW at 2 558 m, 17

In aeronautics, economic and environmental aspects become increasingly important. As those are very much influenced by the frictional drag of the airplane, a reduction of skin friction which causes a major portion of total aerodynamic drag is desirable. One possible approach for passive drag reduction is the application of riblets small longitudinal grooves orientated in flow direction. Through an adapted rolling process, riblets can be brought into metal sheets on a large scale. For this process a thin high-strength steel wire is wound around a work roll to structure it with the negative ribl

During the short flight, Coandă was able to notice the near-fit alignment of the flue gas jets with the airplane fuselage. Later, both Coandă and other scholars have intensively studied the effect that is named The Coandă Effect, in his honor.

Nowadays, worldwide environmental issue, associated to reduction of pollutant and greenhouse emissions are gaining considerable attention. Aviation sector contribution to the whole CO2 released accounts to around 2%, but it is expected to grow in the next future due to increase of demand. Probably, combustion engine design and fuel efficiency have already reached their optimum technology level and only a breakthrough as hybrid-electric propulsion could be able to satisfy the new international more demanding requirements. However, an improvement of the technology readiness level of hybrid-elect

By the strengthening of the economic competition became it apparent a company can’t be valued separate, it should be examined as a complex system. In the assessment of corporate performance is increasingly emphasized the environmental performance. The relevant information of stakeholder about the environmental performance is todays an expection, For this, a management control system is needed, which provide relevant information to managers, hence facilitating the informed decision. This study highlighted, accounting systems are able to meet this demand sufficiently, the accounting means not on

Environmental protection is actively becoming one of the main issues of the Sustainable Development Agenda, and is therefore in the focus of various scientific papers and publications. In the context of vehicle platooning, the environment represents an important area, considering that some of the main goals of this transport technology are to reduce fuel consumption and the reduction of harmful gas emissions. Both goals are achievable when optimizing the speed of vehicles in the convoy, but they also depend on the number of vehicles in the convoy, the type of road they travel on, the weight/ma

Streszczenie:

Increasing knowledge about the risk of toxic effects caused by anthropogenic mercury accumulation in ecosystems has resulted in a growing pressure for reduction of the discharge of mercury waste. Consequently, the mercury waste problems of dental clinics have been given increased attention, and restrictions on handling and discharge of contaminated waste have been established in several countries. Major amalgam particles from trituration surplus of those produced during the carving and burnishing of new amalgam restorations are generally collected in coarse filters and sold for refinement.
