Introduction

When using an internal aerodynamic model, an unsteady aerodynamics model must be defined, such as the Morison model.

Notes

The following data can be specified when using the Morrison unsteady hydrodynamics model.

  1. If flag @QUASI_STEADY = YES, the quasi-steady version of Peters model is used, i.e., unsteady aerodynamic terms are ignored. (Default value: @QUASI_STEADY = NO).
  2. If flag @PROFILE_DRAG_AIRLOADS = YES, corrections to account for profile drag loads will be added to the airloads. (Default value: @PROFILE_DRAG_AIRLOADS = YES).
