It will be difficult for us to accept awards that require us to sponsor third parties web addresses. Recently I found out that one of these links (awarded for “Internet’s leading web-portal for educational/scholarly resources”) pointed to a porno site. It is hard to believe that American Universities allow their names to be used for such purposes. It’s a shame.

December 1, 2001

Lots of inquiries concerning a book version of the web site and the CD-ROM version with the aerospace database. I do not have time to write a book (possibly in the future). A CD-ROM version is charged 25 British pounds (or equivalent in Euro), to cover our costs of recording, shipping and handling.

I have received some inquiries, apparently suggested by my short notes on the history of aeronautics. Like many other fields of human endeavour, credits are not always clear. Here are a few questions : Who is the inventor of the airplane ? – Who is the inventor of the helicopter ? – Who is the inventor of this and that ? — Well, the answer is not always clear. This web site is not a forum of historical credits, but I would like to invite readers who have truths to tell to do so with the help of documents.

I was asked why I do not charge users to use this web site. The first answer is that on the internet people expect information to be free. No students or professionals would be paying a cent unless they are locked in. Second, by keeping the access free, I got the traffic to increase to over 1,700 users (unique IP numbers) every week (about 6,000 users/month). Third, I try to make business by providing consulting and engineering services in all the technical fields related to this web site, with the laboratory support of my institution, if needed. From a research point of view, the questions I receive are incredibly creative.

I received a number of emails with questions concerning Bernoulli’s equation, pipe flows, airfoils and other basic fluid dynamic problems. These items are not found in this web site, because I focused on advanced topics. If there is something basic you need, please check one of the general books reported in the Reference Desk.

Many search engines have indexed single pages. Readers retrieving each of those pages could not navigate the site. I have re-designed the pages so as to have a pointer to the home page, while maintaining the frames versions. Frames or no-frames remains an issue. There are still problems when moving Forward with the browser.
I thank Claire Dormann at the Center for Tele Information at DTU for her technical advise.

A number of technical books on subjects covered on this web site is now available from the author to educational institutions. These books are free and will be shipped at the author’s expense to foster technical education in developing countries. The books can be shipped in batches of four to five, to Countries outside Europe, North America, Japan and Australia.

Please write to the author, with full name and address, expressing your particular needs. Institutions only. No private individuals, please.

The site has taken off. I found it amusing to see which search terms are used. Here is a partial list extracted from the log files relative to the last two months (the analysis program was analog4.0).

reqs: search term
----: -----------
 219: aerodynamics
  87: drag
  85: wing
  57: car
  53: ground
  40: and
  39: aerodynamic
  35: in
  34: coefficient
  30: effect
  29: metasearch
  27: lift
  26: airfoil
  25: wings
  25: high
  24: effects
  24: speed

  24: of
  24: vortex
  23: fluid
  22: racing
  22: grumman
  21: aviation
  21: airfoils
1295: [not listed: 511 search terms]

It is difficult to keep a keyword index of over 500 terms. However, the search engine and robots traffic (on average 15 spiders/week) indicate that searching through keywords is the main form of retrieving information.

December 1, 1999

I have received emails from people asking to ship them books (to Egypt), papers (to Cuba), computer programs (many places). I have made it clear that this is not possible without incurring in a copyright infringment. I do understand that for some people and in certain parts of the world it is difficult to have access to hard copies of important publications, but I can do no more.

Other people skillfully avoid identifying themselves, so there is no way for me to find out whether a certain student at the University of California (which campus ?) really has to write a science project on aerodynamics. What bothers me most is that their email address is [email protected] or [email protected].
