Wing-body-nacelle-tail configuration, one of the configurations for DPW-8
The Challenge
Advance state of the art in both the DPW and AePW fields while collaborating and advancing multidisciplinary aerodynamics topics. A rich knowledge of seven Drag Prediction Workshops and three Aeroelastic Prediction Workshops will be leveraged.Structure
- This is a true collaborative effort between the two workshops and not simply co-location of the two workshops
- Comprised of three to six Technical Working Groups, each of which investigates a given topic in greater technical detail
- Some Technical Working Groups will be DPW-focused while others will overlap with the Aeroelastic Prediction Workshop
- At the workshop, the DPW and AePW communities will meet separate for part of the time and together for a final joint session
- A low barrier to entry will be provided for student participants
Objectives
- To build on the success of Drag Prediction and Aeroelastic Prediction Workshops
- To provide an impartial forum for evaluating the effectiveness of existing tools and methods
- To identify areas needing additional research and development
- To develop the infrastructure for future multidisciplinary workshops
General Information
- This workshop is open to participants worldwide. Efforts will be made to ensure representation from all areas of industry, academia and government laboratories.
- Efforts are being made such that submissions can range from the simpler test cases through highly-advanced methods.
- Student participation encouraged through reduced computational requirements and decreased registration fee. (Graduate and undergraduate students)
- Participation in the CFD studies is not required to attend the workshop. Everyone is welcome!
- Open forums will be included in the workshop to discuss the solutions and modeling techniques.
- Results will be made available after the workshop in a report and on the DPW website.
- A registration fee will be required for attendance.
- AIAA membership is not required.

Working Group #1: Source of Scatter Working Group
Leads: Marshall Galbraith, Ed Tinoco, and Raj NangiaThis is similar to the traditional DPW approach for transonic flow on a static geometry. This group will concentrate on identifying the reasons for data scatter that was observed in DPW-VII.
Working Group #2: Static Aeroelastic Deformation Working Group (with AePW)
Leads: Ben Rider, Stefan Keye, and Garrett McHughFluid-structure interactions will be calculated and studied in detail. This group will be comprised of individuals in both DPW and AePW communities with significant collaboration leading up to the final workshop.
Working Group #3: Buffet Working Group (with AePW)
Leads: Brent Pomeroy, Bret Stanford, Andrea Sansica, Daniella Raveh, and Hadar Ben-GidaThis group seeks to identify nature of pre- and post-buffet flight regimes with unsteady CFD analysis. Simulations will be performed on both experimentally-measured deformations and with coupled fluid/structure interactions. Members of the DPW and AePW communities will be involved.
Working Group #4: Wind Tunnel Test Environment Working Group
Leads: Melissa Rivers, Ed Tinoco, and Ben RiderThis group seeks to understand the impact of the wind-tunnel environment when compared to free-air CFD, in particular both forces and moments as well as surface pressures.
Students
Students, both graduate and undergraduate are encouraged to attend and submit data for the workshop. Individuals can participate in any of the four working groups. Efforts are being made to minimize barrier to entry such that students can attend the workshop and interface with technical experts. Student submissions do not need to achieve all of the components of a specific Test Case. Instead, students are welcomed and encouraged to submit whatever data they have generated, no matter how small the database. A significantly-reduced rate will be charged to students.Geometry
Geometry for DPW-8 available for download.Experimental Data
Experimental data for the NASA Common Research Model and ONERA OAT15A airfoil is publicly available.Grids
Committee-supplied grids are being generated in multiple formats from two commercial partners (Helden Aerospace and Cadence. Standard gridding guidelines have also been developed.Data Submission
Data should be submitted in the workshop-standard format to enable the Committee to do ensemble data analysis.Email Updates
