The dimensions following were determined from the 4 inch rocket CATIA model. I want to be sure these dimensions are correct before procede
TWA: Total Wetted Area WSA: Wetted Surface Area
Maximum outer diameter of rocket 9.843 cm Inner diameter of rocket 8.89 cm Total body length including nose 166.668 + 36.232 + 11.12 = 214.02
Nose Cone Tip Length 11.12 cm Maximum diameter 2.354 cm Total wetted area (TWA) 41.379 cm^2 Nose Cone (not including tip) Length 36.232 cm Maximum diameter 9.843 cm TWA
Total Nose Cone (WSA = Wetted Surface Area) Length 11.12 + 36.323 cm = 47.443 cm WSA lateral surface area First body tube Length 60.643 cm TWA 1875.134 cm^2 Motor case Length 81.915 cm TWA 3279.031 cm^2 Fins Fin span 14.478 cm Fin root chord 24.13 cm Fin tip chord 11.938 cm Fin thickness .165 cm Material Fin Can Thickness of protuberance .159 cm TWA (approximated) 694.072 cm^2 Length 24.13 cm Other Protuberances Bolts .159 cm
Questions: Where does the baseplate go? Where does the short stack go? What is the forward closure, and where does it go?
