Remarks

0. General overview

In this type, normalized roll, pitch and yaw rates for quasi-steady rotations can be specified. All three values are nondimensionalized in the same way and are set to a default value if the corresponding subnode is missing. For loadcase computations, all values are having a default of 0. In case of positive quasi steady rotations within a performance map computation, the positive defaults of +0.003 are used. In case of negative quasi steady rotations within a performance map computation, the negative defaults of -0.003 are used.

1. <pstar> (optional)

This is the normalized roll rate pstar. The roll rate p [rad/sec] is nondimensionalized by: pstar = p * reference length (CMY) / flow speed. The default value is 0. for loadcase computations and +/-0.003 for performance map computations (see section 0).

2. <qstar> (optional)

This is the normalized pitch rate qstar. The pitch rate q [rad/sec] is nondimensionalized by: qstar = q * reference length (CMY) / flow speed. The default value is 0. for loadcase computations and +/-0.003 for performance map computations (see section 0).

3. <rstar> (optional)

This is the normalized yaw rate rstar. The yaw rate r [rad/sec] is nondimensionalized by: rstar = r * reference length (CMY) / flow speed. The default value is 0. for loadcase computations and +/-0.003 for performance map computations (see section 0).
