DESIGN, DEVELOPMENT AND INITIAL TESTS OF ONR SUPERCAVITATING HYDROFOIL BOAT XCH-6
Abstract
The XCH-6 is the first supercavitating hydrofoil open water test craft. A total of 13 hrs, 48 min. of development testing was completed. The testing and development work produced a craft which is statically and dynamically stable about all 3 axes over the speed range from 0 to 50 mph. Cavity flow conditions are also stable. A pitching instability problem due to air entrainment around the pod, as well as various other structural and flow problems encountered, were resolved. The General Electric T-58 gas turbine power plant was modified, to provide resistance to the effects of operation in a salt laden atmosphere. Specifications for modification, operation and maintenance of this engine were developed. A 200 hp, 6000 rpm, right angle, over-the-stern drive in a minimum size envelope was designed, fabricated, tested and modified to provide power transmission to the propeller. (Author)
