Comments

  1. The degrees of freedom defined with this entry represent rigid body motion in the reference coordinate system defined on the AEROS entry. The standard labels that define the various rigid body motion are:
    Table 1. Standard Labels Defining Rigid Body Motions
    LABEL Degree of Freedom Motion Description
    ANGLEA ur (R2) Angle of Attack
    SIDES ur (R3) Angle of Sideslip
    ROLL ˙ur (R1) Roll Rate = pb/2V
    PITCH ˙ur (R2) Pitch Rate = qc/2V
    YAW ˙ur (R3) Yaw Rate = rb/2V
    URDD1 ¨ur (T1) Longitudinal
    URDD2 ¨ur (T2) Lateral
    URDD3 ¨ur (T3) Vertical
    URDD4 ¨ur (R1) Roll
    URDD5 ¨ur (R2) Pitch
    URDD6 ¨ur (R3) Yaw
  2. The degrees of freedom defined with this entry are variables in the static aeroelastic trim solution, unless they are constrained by referencing them with a TRIM Bulk Data Entry.
