Canard controlled rocket and roll reversal
Hey all!
I am currently working on making a canard controlled rocket (only the roll is controlled!) as part of a student project. I am currently working specifically on the roll control, which means the canards, and as such investigating the potential for roll reversal due to the negative aerodynamic effects of canard deflection on the tail fins (canard-tail interference for example).
The rocket we are working on would be 2.4m in length with a diameter of 16cm and flying around Mach 0.6. From my research, a rocket of this scale and speed should not be subject to roll reversal, and would most likely only suffer from a (slight?) reduction in roll control authority.
Still, I would very much like to be able to closely study the aerodynamic effects of canard based roll control, notably to be able to optimise the position and dimensions of the canards to minimise negative effects.
Therefore, I was wondering if there were any tools I could use to simulate these effects, and notably be able to calculate the total roll moment coefficient as a function of the canard deflection angle and/or dimensions, without having to resort to CFD (I would like to find a more time efficient alternative :) ). I am aware that Missile DATCOM is often used for this (it popped up a lot in my research), but I am not in the US so...
If you have any leads/recommendations for appropriate tools/software/methodology I could use, it would be highly appreciated!!
Thank you in advance
