Dynamo

Last updated: March 14 , 2003

Dynamo: A series of Rockets I designed to learn the basics of clustering & air starting multiple motors on different Cluster configurations . Currently I have 2 real  versions . That consist of  4 in. Loc Air Frame 3 Fins & a payload section that is shared between the different boosters .
Dynamo 1 .062 G 10 fin with 7 - 29 mm. motor mounts .
Dynamo 2 1/4 ply fins with  core 38 mm. & 6 - 24 mm. motor mounts .
Krazzy-Kluster Dynamo 2 was lost @ a Maryland Tripoli launch , 
but I still have what's left of the booster /fin can section . 
The next in the series will be Dynamo 2b or will be known  as:
Krazzy-Kluster  or Krazzy-K for short .

It will consist of 4 inch diameter Loc tubing  with a central 38 mm mount surrounded by 6-24 mm same as Dynamo 2 . 
It will differ in the ways that it will also have 6 outer pod type 29 mm motor mounts for a total of 13 motors

Dynamo 1
Not much to see
On a Cluster of :  H 220 & 2 F 101 ground started
with 2 G 35 air started . Only 1 G lit , but  the rocket was still able to achieve an altitude of  1,903 ft.
Wrasp said about 2,500 ft if all of the motors lit .This was it's 6th flight .

& It's  being  repaired !
All I have left from the flight is the tail section .
It had to have a panel btween the fins replaced .
One of the F 101's catoed ( never to be seen again )
& blew out one of the 24 mm motor tubes .
