There are two types of drag on a rocket; induced drag, and profile drag. Induced drag only occurs when the fin creates lift. ... So if your rocket is flying slow, and has very small fins, the Reynolds number might be so low that the fin will be very ineffective (because the Coefficient of Lift will be smaller).

RockSim calculates the CP at 11.465 inches from the tip of the nosecone on the rocket. The fins have the right shape and the simulation indicates more stability than when using just one set of six fins as above (CP at 10.993 inches).

As you can see, the fins are not cut uniformly. And the root edge is not flat. That must be fixed, as the edge must mate well with the body tube to glue well, and it must be squared with the flat so the fin will stand up straight.. ... Snap Dragon; Scratch-Built Model Rocket...

Dear User, Let us assume that we are working with a simple-minded, straight-nozzle rocket, of the type that is sold by Estes. We should also assume that we are talking about absolutely equal fins - uniform in size, shape and weight.

A multidisciplinary effort was undertaken to investigate the effect of structural loading on a rocket of interest to the U.S. Army. This report addresses the element of aerodynamic loading. ... The results provided the aerodynamic loading component used during the initial portion of the rocket flight.
