For those who know sounding rockets, this info may be well-known, but bear with me, I'm still learning where to look!
The Deacon and the Cajun were basically the same case and fins, but different propellants. Cajun had about 30-40% better performance with the same payload.
Same holds for the Nike-Deacon (DAN) and the Nike-Cajun (CAN). The only dimensional differences will be a result of different payload compartments. Parts for one were virtually interchangeable with the other.
Looks like the most-common nose cone was a conical, about 34.2" long. Translation, a 3.4" conical balsa nose cone will be very close.
Below is a corrected Deacon / Cajun single-stage rocket, using a 26.6" (2.7") payload section, 107" motor section (10.7"), and a 34.2" conical nose cone (3.4"). The fins are also corrected from the previous file, which were grossly oversized...
Length: 16.80"
Diameter: 0.65" (ST-6)
Fin Span: 2.05"
Weight: 0.47 oz
1/2 A3-4T......314'......Dv 6 FPS.......36" x 1/8" rod
A3-4T..........688'......Dv 32 FPS......36" x 1/8" rod
A3-5T..........695'......Dv 4 FPS.......36" x 1/8" rod
Note to Carl: Take a look at the last line in the simulations above. Could a 5-second delay be worked into a 1.75" 13mm casing, using the DECAP style motor?
I'll try whipping out the Nike booster next...
Enjoy!
