Project summary

Project content is the conduction of complex research, including the development of methodical problems and performing the flight experiment for evaluation and working out of recommendations on realization of possibilities to reducing the harmful impact of civil aviation airplanes on environment (community noise and contamination of atmosphere), and also the forming of scientific and technical backlog of evolution of the technology to airborne monitoring of the Earth, waters and atmosphere on the basis of modern high technologies for obtaining and processing the information.

Purpose and methodology of project.

The purpose of project is the support of fundamental and applied research, and technical developments in the area of environment protection. With this end of view it will be carried out:

– investigation of atmosphere contamination from aircraft engines emission on the cruise flight of airplanes;

– development of the methods to reducing the civil aviation airplanes' impact on environment (community noise and contamination of the atmosphere);

– development of proposals on creation of the aviation complexes for airborne monitoring, realizing the methodology of complex monitoring of the Earth, waters and atmosphere;

– development and realization of complex methodology of theoretical and experimental (including flight) research.

Expected results.

Project #627-3 is the final stage of Projects #627 and #627-2.

In the course of performing the Project it is supposed the following:

– for using the results of modeling and flight experiments, it is necessary to develop recommendations on realization of non-standard optimal trajectories of descent (climbing) and landing approach (takeoff), providing the noise reduction with regard to the typical features of particular airfields;

– to develop operationalmethods for studying the aeroengines' emission effect on atmosphere pollution in the cruise flight conditions, and to make an assessment of that effect under actual conditions, using the results of flight experiment and modeling;

– to develop the recommendations on effective methods of integrated airborne monitoring of the land, water area and atmosphere, based on application of various band aids and the procedures for automated information processing.

On the first Subject of the Project.

As a result of performing works, related to the category of applied research, recommendations on realization of non-standard procedures of piloting at takeoff and landing will be developed and verified in the flight experiment These procedures will permit the reduction of the community noise by 3-5 dB, taking into account the prospects of development of systems of communications, navigation, surveillance and air traffic management (CNS/ATM), thereby satisfying. the flying safety requirements.

The methodology of refining procedures, suggested for various airfields, will be developed. The configuration of the minimum airborne and ground-based equipment suite will be defined, providing the required quality and safety of the aircraft control.

On the second Subject of Project.

The research now under way has a fundamental and applied value, both for the purpose of gaining new knowledge about influence of aeroengine emissions on pollution of the upper troposphere and lower stratosphere, and with respect to the creation of related methodical support and experimental facilities to expand the full-scale investigations and the airborne monitoring of the atmosphere contamination.

Experimental data will be obtained on the change of the composition of engine's emission products in the propulsion jet and along the airplane wake under cruise flight conditions, and also in the zone of influence of the busiest air corridor over territory of Russia.

Statistical and spectral characteristics in the aircraft wake (distribution law, turbulence intensity, timing and spatial scales of urbulence) will be obtained.

Recommendations for the definition of engine emission values under cruise flight conditions will be developed by the conversion of data, obtained in ground measurements, by means of mathematical modeling of combustion processes, or by direct onboard flight measurements.

The obtained results will be used to verify the mathematical models for determination of aeroengine emission product composition under flight conditions and their interaction with the atmosphere for single aircraft, in regional flight corridors and on the global scale.

Research on Subject 2 has goals concurrent with objectives of the "Aircraft Emissions and Reduction Technologies" project (AERONET), supported by the European Commission, DG Research, Aeronautics.

Results, obtained on the final stage of performing works on Subject 2 of the Project #627-3, may serve as a basis for further development of the project, and closer correlation with the European program, for example through AERONET.

On the third Subject of the Project.

Development of recommendations on creation of aviation integrated systems, consisting of: the aircraft, airborne equipment, the ground-based systems for data analysis and presentation, and software, resolving optimally the problem of obtaining data about ecological state of terrestrial surface, water area and atmosphere (on particular examples).

The technology developed is envisaged to extend the capability of applied science to obtain spatial information on the state of terrestrial environment, which is needed for environmental impact assessment, prevention and mitigation of environmental hazards and planning of nature-protection measures.

The hard and software developments should substantially increase the efficiency of airborne monitoring and improve the availability and access of local ecological services to useful environmental data..

The results of the work will serve as a basis of discussion for further continuation of the project and more intense future collaboration with European partners in the context programmes such as the GMES initiative.

According to the Minutes of seminar on the Project # 627-2, that was held in Cologne 23-24 April 2001, investigations, developments and flight experiment, planned in the Project # 627-3, are well corresponding to work conducted on similar subjects in Europe (SOURDINE-2, GARTEUR, X-NOISE programs on subject 2, GMES program on subject 3 and oth.).
