| The Netherlands introduces us to
Henk, who brings to us this interesting design fashioned in the form of a swallow's tail. Henk provided the following information with his entry:
Hallo,
I like to enter my design
“Zwaluw” in to the Design of the Month competition. Zwaluw is the Dutch
name for swallow. The name of the rocket is chosen for its big triangular fins,
resembling the tail of the swallow bird.
On the CD you will find
drawings, part list, photos from the static model and photos from the launching of the
Zwaluw and a video of the launch and the recovery. Al the documents are in Adobe
Acrobat format (pdf). The pictures are in JPG format.
The design was done with
SpaceCad. SpaceCad is a very popular rocket design program in Europe. The design file is
included on the CD, as is a 30 day evaluation version of SpaceCad.
The video is included on
the CD in tree formats, AVI (for the windows media player) and MOV for the QuickTime
player and a MWV file for the download from a website. The MOV is the original file. The
AVI and MWV files are conversions of the MOV
file.
The Zwaluw was launched
tree times on June 26th and 1 time on July 24th 2004
The first time it was
launched on a B4-4. It left the launch rod so fast we ware unable to make any launch
pictures.
The second time it was
launched on a A8-3. Just to give the photographers a change to make a picture. It flies
very nice on a A8-3. It left the launch rod with a very gentle “whoooosh”. The
launch pictures are from this launch.
The third time the Zwaluw
was launched on a C6-5. Oh boy, push the button en start walking right away. The rocket
wend completely out of sight. We were very glad to see it coming down on the streamer.
It was a day with a lot of
wind. So I opted for a streamer. But I had to walk a long way to get the rocket back.
The launch on July 24th
was just for fun with a Sachsen C6-3. The Sachsen has les power as an Estes C6 and burns a
little longer. It was a very calm day so I used a Fliskits 12 Inch parachute. That was a
mistake. I had to walk at least 1,5 Km ( 1 mile ) to get the rocket back. Oh well,
rocketry is not only fun but very healthy!
Sincerely,
Henk
