Hello everyone*
For stack* designed as per STS-1* i am in a situation that critical velocity is lower than design velocity.
So far i know by introducing helical strakes or other attachments* critical velocity can be increased.

But how to evaluate critical velocity after introducing strakes.

Please provide your opinion/ guidance on same.
