For those interested, I did post about this launch under my thread “Brazoswood High School 2018 WSMR Launch”

Yes, I read all of his posts at the time they were posted and learned a lot. I also took his advice. Of course some of it was way over my head because I was in high school, but I did the best I could, even learning along the way. It was a very far stretched goal for a high school team, however...

I think that will be good. The R powered rocket I designed in high school had a 9.6” steel tip (needed the weight for stability, was in a time crunch) we also looked at manufactured nose cones from various companies and measured their length ratios (tip : full length of nose cone) and took a...

Okay, thanks!

Does this finite analysis come on the 2018-2019 student edition of solidworks?

I see that the fin can is made out of aluminum. What are the fins themselves made out of? And what airfoil do you plan on using? Also what speed and/or altitude are you optimizing for (where will you spend the most time in flight but what is your projected apogee and max speed?)

Thank you Dave!

Awesome! Thank you so much. I hope for the best!

Well, I'm not necessarily an "engineer" yet, but I love problem solving, even under pressure. It is the reason I want to become an engineer. Of course as a college student I continue to learn as I go and learn from those around me. I love rockets and they continue to fascinate me. So if I'm not...

Howdy! My name is Noah Carter and last year I was the Dynamics Manager for my high school's rocketry team (2018 Brazoswood Goddard Team, flight video is on youtube). We launched an R-motor to 28,000 ft (with only 40% oxidizer load). Now I am attending Texas A&M University (Freshman, College of...

For those who remember me (it's been a while), my high school, Brazoswood High, "successfully" launched our 19.5 ft, 328 lbs (dry mass), hybrid R class motor (rough avg 10,000 N) to 28,572 feet (msl) on June 23, 2018. The reason I said "successfully" was because we had a leak at the top of our...

5:1 Conical

Yes, we need the tip to take on the aerodynamic heating and for structure. Mainly the heating. Max velocity ranges from 2.7 - 3.12 mach (still designing).

Conical

I am trying to figure out how long the nose cone tip should be. I didn't know if there was a ratio or something to find how long the tip should be.

Howdy, does anyone know a ratio for nose cone tips? Nose cone dimensions: Length- 38 inches , Diameter- 7.74 inches

Does anyone have a spreadsheet that can calculate fin flutter?

Okay, thanks so much!! Sent from my iPhone using Rocketry Forum
