A design evaluation was made of the previously proposed captive trajectory support (CTS) concept utilizing an existing cantilevered sway-strut mechanism. The evaluation showed that the existing strut was structurally inadequate to handle the aerodynamic and gravitational loads. A full-span, moving-strut concept was examined and proved adequate to meet the requirements of model position accuracy and motion. If procurement is started in FY8l, the CTS could possibly be operational in late FY82.
