 Figure 5-10: Second Doublet Command to Morphing Servo


 The roll rate and yaw rate responses to the second morphing doublet are shown

in Figure 5-11. It can be seen that the morphing doublet commanded in the second

maneuver was of a slightly larger magnitude than the first maneuver. This results in a

larger roll rate response due to a larger morphing deflection.

Yaw Rate(right)



 It is also seen that there is a minimal yaw rate response from the actuation of

a larger morphing deflection. Therefore, it similarly resulted in an almost pure roll

motion with a slightly faster roll rate response than with the previous maneuver.

 5.4 Modeling

 The data from open-loop flights is then used to approximate a linear time-domain

model using an ARX approximation [18]. This model is generated by computing

optimal coefficients to match properties observed in the data.
