Hi, i'm curious is there a recommended ratio of rocket length to diameter for the most efficient design?

I hope this post finds you all soaring high in your rocketry adventures I'm a high school student currently navigating through the fascinating world of water rocketry for my research paper My focus is on the optimization of water rocket fins in terms of their size. We’re a university team just getting started with building model rockets, and one of our main goals is to develop an active control system We’re currently debating between using movable fins (canards) or thrust vector control (tvc). For example, this will not be the desired result if the rocket comes out of the pad and after it spins around a bit and stabilizes the angle at which it rotates

How can i determine the correct choice of canards for a rocket going 2 mach It is really difficult to guess how the canards selected with the created program control the rocket. I have a tall/thin rocket with a fineness (aka aspect ratio or length to diameter ratio) of ~26 (80” long 3.1” diameter) As currently configured, it has a stability margin of 3.7/14.6% in openrocket I'm still new here, and it's a pleasure to meet you all If it's not too much of a bother, i like to get some advice on making a model rocket kit fly higher

Like a few general tips that can be used before/during launch

Or maybe some slight modifications that can be made to a model rocket.

Long story short i just got my level 1 over the weekend and flew it low and slow But now i might like to reach for the stars as it were lol I'm terrified of losing my rocket though and am contemplating investing in some sort of tracking system

I know these egg timers are suggested but yes. Aftershock ii has officially become the highest and fastest amateur rocket of all time After a thorough internal review, the. Large and dangerous rocket ships
