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 gained knowledge during their curriculum in practise, by building rockets.

Rockets

In the last years the following rockets were build and lauched

Engines

DARE uses home built and designed rocket engines. Over the years, the following engines have been built and tested.

Engines

SRP (PVC) 180 Ns 1 s
RVD (aluminium) 300 Ns 1.4 s
DX-1 1250 Ns 1.4 s 2.7 kg? 1.2 kg KNO3/Sucrose
DX-1 EE 2500 Ns 1.4 s 2.7 kg? 2.5 kg KNO3/Sorbitol
BigBoy 11000 Ns 5 s 25 kg? 11 kg KNO3/Sorbitol
DEIMOS I (50000) Ns 30 s max 6 kg (indefinite) LCH4/LOX

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.
