  AHS Specialist's Conference on Aeromechanics Fisherman's Wharf, San Francisco, CA, Jan. 23-25, 2008 Sponsored by The San Francisco Bay Area Chapter Topics – This meeting will encompass all aeromechanics disciplines. In addition, advances in computational modeling for the integrated technical disciplines of dynamics, aerodynamics, acoustics, and handling qualities will be emphasized. The Conference will cover the interdisciplinary technologies required for accurate analysis and design of rotorcraft performance, loads, vibration, noise and stability. The reported work will include analytical developments, new experimental studies, and correlation/validation efforts. Analytical papers may range from basic aerodynamic flow prediction of rotors to results from comprehensive analysis programs (both with and without coupling to computational fluid dynamics). Experimental papers will span model- to full-scale wind tunnel and flight test programs. Test and evaluation studies enabling insight, improvement and an improved means to design rotorcraft are also desired. Finally, revolutionary new rotorcraft concepts or applications of emerging aeromechanics technologies to new rotorcraft missions will be addressed. (See below for individual disciplines) Abstract Submittal - Abstracts should be written in English and should be no longer than five pages, including background, approach, key results, conclusions, and sample supporting figures. The approach and results should be presented in sufficient detail to allow the reviewer to determine the quality, scope, significance and current status of the work that will be described in the final paper. Priority will be given to abstracts and papers containing significant results and conclusions. Submit abstracts, including paper title, author(s), name(s), address, phone, fax and e-mail address by no later than July 25, 2007. Electronic submittal in PDF file format is required, either by e-mail or CD-ROM. Completed Papers - Authors will be notified of final selection by August 8, 2007. Presentations will be given in an open forum and all papers will be published in the meeting proceedings on CD-ROM. Final papers in electronic format are due on December 15, 2007. The author is responsible for any necessary clearances and approvals. All questions should be directed to the Technical Chairman: Dr. Roger Strawn, US Army AFDD, rstrawn@mail.arc.nasa.gov, (650) 604-4510.
Dynamics - Papers are invited in all areas related to advanced rotorcraft dynamics and aeroelasticity. In particular, papers that provide a better understanding of rotor aeroelasticity and the associated dynamic behavior of the coupled rotor and airframe are solicited. This includes papers that report novel design approaches and analytical methodologies that lead to improved rotorcraft dynamic behavior in the areas of loads, vibration and stability. Papers reporting on the development of rotorcraft dynamic or aeroelastic analyses and experimental validation, using model or full-scale test databases, are especially encouraged. Reports of new experimental results, when supported by sufficient documentation, are also appropriate. Papers reporting on the impact of advanced dynamics technology on the reduction of total rotorcraft costs are particularly relevant. Priority will be given to completed programs where significant conclusions are substantiated and the results contribute to advancing state-of-the-art rotorcraft design and analytical modeling. Aerodynamics - Papers are invited that address recent accomplishments in all areas of rotorcraft and VTOL aerodynamics, including UAV configurations. Topics of interest include, but are not limited to, computational fluid dynamics techniques, wind tunnel and/or flight test results and correlation. For example topics which cover combinations of computational fluid dynamics with computational structural dynamics, flow visualization methods and results, aerodynamic design methods for components or complete aircraft, unique aerodynamic modeling capabilities, and computations or measurements of high angle of attack, unsteady, interactional or vortical flows are welcome. Priority will be given to works where significant conclusions contribute to advancing the state-of-the-art in rotorcraft aerodynamics understanding, analysis, and design. Acoustics - Papers are invited addressing recent advancements in the study of both interior and exterior rotorcraft noise generation, propagation, and control. Of particular interest are papers on current research in interior noise prediction/reduction and aural detection of rotorcraft. Appropriate topics include the application of finite element and statistical energy analysis based techniques to predict the complex noise field inside rotorcraft cabins, active noise control applications for rotorcraft cabins and crew stations, and novel concepts in engine and transmission noise reduction. Additional topics of interest include external noise prediction methods for manned and small-scale unmanned rotorcraft, improved acoustic propagation models for use in detectability analyses, and psychoacoustics relevant to aural detection of rotorcraft. Research papers leading to a basic understanding of fundamental aerodynamics noise sources such as rotor harmonic noise, impulsive noise and broadband noise are also welcome. Papers documenting wind tunnel or flight test acoustic measurements, acoustic data acquisition/reduction/analysis, rotor noise reduction techniques, noise abatement flight operations or implementation of national or international civil noise regulations are also encouraged. Handling Qualities - Papers are invited which address handling quality issues relevant to aeromechanics. Handling qualities encompass aircraft characteristics which govern the ease and precision with which a pilot is able to perform tasks in support of an aircraft mission. This includes basic vehicle stability and control/response characteristics and the pilot-vehicle-control system. Papers are encouraged on topics which address significant results from applications of mathematical modeling to rotorcraft design, to development and use of handling qualities flight test data, rotorcraft component integration, operational needs and experience, night and adverse weather requirements, terminal area operations, and development of advanced flight control systems. Test and Evaluation - Papers are invited which address all aspects of rotorcraft and VTOL testing, including evaluation of components and subsystems. Of particular interest are papers that discuss flight and wind tunnel test results from model or full-scale testing. Papers that address evaluation of innovative flight procedures, new test techniques, and novel control systems are also highly desirable. Especially encouraged, are papers regarding operational and environmental problems that are encountered in the low-speed flight regime when operating and testing rotary wing aircraft from either land or ship-based platforms. Papers are encouraged from experiences in all multidisciplinary areas of testing generally classified as aeromechanics, including aerodynamics, dynamics, acoustics, and inner-loop flight controls. |
