Subject: RE: DPW-IV Data Submittal Forms


Here is the updated spreadsheet.  Sorry I forgot to send it out yesterday.  I think Joe is on travel so the web site may not be updated.

 

There have also been a few questions about the bubble location.  I've attached a picture from DPW-III illustrating the measurements.  Please report locations in the global axis system.

We would like to let you know that in the TRIMMED DRAG POLAR section you do not need to include the CD_PR and CD_SF data (these were not included in the spreadsheet calculation).  These data are not needed immediately and can be calculated later if desired.

 

It has also been pointed out that there is a bug in the spreadsheet.  A new version will be sent out Monday.

 

Regards,

DPW Organizing Committee

Hello DPW-IV Participants,

 

The data submittal forms are finally ready.  Thank you for your patience.  Version 3 is the final release if you happened to download the forms before this announcement.

We have also included a spreadsheet to calculate the trimmed drag.

We will start working on the summary plots for the workshop so we can determine a more precise date for the final data submittal.

 

Please let us know if you have any questions.  Thank you for your participation in the 4th AIAA Drag Prediction Workshop.  This is a wonderful opportunity for a blind test of the NASA CRM model, and your participation is greatly appreciated.

 

 

Regards,

DPW Organizing Committee
