Deployable devices have the potential to reduce or eliminate physical constraints placed
on vehicle design while enhancing the aerodynamics characteristics of the system. This
investigation looks at augmenting an existing boost-glide system with a deployable device
to increase the system's range or accuracy by varying design parameters. Two different configurations are considered, one which has a single-delta shape and one with a double-
delta. A rapid robust design methodology that views the multidisciplinary design problem
as a dynamical system is implemented to robustly design the deployable. This method-
ology allows concepts from dynamical system theory to be used in order to broaden the
computational tools available to the MDO problem. In addition to the physical parameters
of the deployable device, the impact of the guidance algorithm is also considered. The
product of this investigation is a family of designs which compare favorably to those obtained through traditional Monte Carlo methods and are achievable in less than 5% of the
computational time. The obtained deployable designs have the capability to enhance the
baseline boost-glide system's 1σ range by 50% and improve the 1σ accuracy by an order of
magnitude. It is seen that the single-delta configuration provides similar accuracy as the
double-delta; however, the double-delta configuration is capable of providing ranges that
are twice that of the single-delta.
