Welkom bij de DARE wiki. De dingen hieronder heb ik nog maar even laten staan omdat er nog wel een paar handige tips in staan.
Delft Aerospace Rocket Engineering (DARE) is een studentenvereniging met als doel studenten de gelegenheid te geven om zelf amateur raketten te ontwerpen, bouwen en lanceren. DARE is verbonden aan de vliegtuigbouwkundige studie vereniging Leonardo Da Vinci van de faculteit Luchtvaart- en ruimtevaarttechniek (L&R) van de Technische Universiteit Delft. (TU Delft).

History
DARE was created in 2001 by six enthousiast Aerospace Engineering students, studying at the Technical University of Delft. These students had a craving to apply the knowledge gained during their curriculum in practise, by building rockets. In 2005 DARE has joined the 'Universalis' foundation. This foundation enables DARE to handle its own business on their own account. To learn more about Foundation Universalis, surf to Stichting Universalis

Raket stabiliteit
De stabiliteit van een raket is de neiging van de raket om terug te keren naar zijn evenwichtspositie. Een amateur-raket werkt meestal met passieve stabiliteit. Deze kan worden verkregen door het bevestigen van vinnen aan de raket. Voor de stabiliteit van een raket zijn twee punten van belang, het zwaartepunt en het aërodynamische drukpunt.

Other optional things to do
- Control the rights of anonymous and logged in users through the Control Panel (which can be found in the toolbox on the left side of this page).
- Add the url for your wiki to the Categorized wiki list. Simply edit that page and put your wiki under the appropriate category.
- To increase the amount of space you have for uploads, add links to http://editthis.info from external sites, and go to the Link Quota Page to increase your uploads quota.
- Edit MediaWiki:Sidebar to change the navigation menu
- Add this wiki to some external wiki indexes:
- If you are feeling adventurous and know a little about web design you can edit the javascript and css to the Header to change the look of your wiki.
- You must log as admin to do this
- Whatever you enter in this page will be added to the html in the header after the standard style sheet, so you can override styles.
- Read the User's Guide for other usage and configuration help.
- Add your wiki to the map of wikis
- Add a message to the Feedback Page if you see anything that could be improved.
