The parametric study of the ion collection parameters for free molecule flow has been completed for the range of values of practical interest. It has been found that fairly simple relationships can be established for the variation of the ion flux coefficient as a function of any one of the flow parameters Debye number, speed ratio, and applied potential. Results for the transitional regime show trends similar to the collisionless case. Investigation of vehicle angle of attack and internal molecular degrees of freedom on the ion flux have been started, but preliminary results indicate the effects on the flux coefficient are small.
