Aerospace How much do spoilers increase drag coefficient?

  1. Mar 12, 2010 #1
    Approximetly how much is the drag coefficient if orginally the coefficient is 0.02689. I know it depends on aircraft etc but im only looking a rough estimate.

    As a first order guess, spoilers are a flat plate. But, what outside sources have you consulted?

    what do you mean by outside sources?
  5. Mar 12, 2010 #4
    Books, AIAA journal papers, NASA technical server, etc. What exactly are you trying to model here?

    i am modelling the braking system. so i need to know how much drag the spoilers provide to enhance my model
