The LiftDrag system computes lift and drag forces enabling simulation of aerodynamic robots.
The following parameters are used by the system:
link_name : Name of the link affected by the group of lift/drag properties. This can be a scoped name to reference links in nested models.

- entitiesFromScopedName to learn more about scoped names. air_density : Density of the fluid this model is suspended in. area : Surface area of the link. a0 : The initial "alpha" or initial angle of attack. a0 is also the y-intercept of the alpha-lift coefficient curve. cla : The ratio of the coefficient of lift and alpha slope before stall. Slope of the first portion of the alpha-lift coefficient curve. cda : The ratio of the coefficient of drag and alpha slope before stall. cp : Center of pressure. The forces due to lift and drag will be applied here. forward : 3-vector representing the forward direction of motion in the link frame. upward : 3-vector representing the direction of lift or drag. alpha_stall : Angle of attack at stall point; the peak angle of attack. cla_stall : The ratio of coefficient of lift and alpha slope after stall. Slope of the second portion of the alpha-lift coefficient curve. cda_stall : The ratio of coefficient of drag and alpha slope after stall. control_joint_name: Name of joint that actuates a control surface for this lifting body (Optional)
