Abstract:

Resistance data are presented for a simulated Captured Air Bubble CAB landing vehicle configuration operating over calm water. This particular CAB configuration uses a flexible, fabric bow seal instead of the more usual planing ski. Two center-of-gravity positions are considered and comparison is made with the performance of a hydrofoil vehicle of the same size. General indications are that minor changes in center-of-gravity location can have considerable effect on the vehicle trim attitude and performance. Also, in terms of drag-to-weight ratio, the over-all performance of the CAB configuration exceeds that of the hydrofoil configuration at normal mission operating speeds. However, the CAB configuration tested would not have adequate stability in roll. Author
