Hey everyone,
I'm working on a 3" min diameter rocket, and I'd like your opinion on going drogueless vs using a streamer for most of the descent until the main deploys. The nosecone separates from the body tube, and that's the only separation point. I'm going to use cable cutters to keep the main wrapped in a nomex burrito until deployment. My expected altitude is ~35,000 ft.
Total rocket weight after motor burnout: 12.5 lbs
Weight of nosecone and everything in it: ~1 lbs
Weight of body tube and everything in it: ~11.5 lbs
Length of nosecone (including shoulder): 20.3 inches
Length of body tube: 55 inches
Number of fins: 3
I've never used a streamer, though I have flown another rocket a number of times with a standard DD config using a drogue and main chute. If you recommend a streamer, can you help me determine the width and length? I haven't been able to find any good design guides for sizing a streamer properly.
Thanks in advance,
Bryce
