This project is concerned with the development of design and test methodologies for hovercraft.
Full-scale hovercraft field-testing is to be achieved through the dedicated re-design and re-construction of the ABl11Crossbow hovercraft. The Crossbow hovercraft is an experimental craft, which was built in England in the early seventies. The Crossbows re-design focuses on the production of a versatile craft, which is capable of modification to produce a variety of different operating conditions. The re-design and re-construction comprises several distinct areas. An improved and adjustable lift and thrust system is designed. The design and manufacture of a new more stable and versatile skirt is undertaken with a strong emphasis on replacibility and testing of whole and individual skirt components. A lighter and more corrosion resistant “Nomex” honeycomb material replaces the original aluminium honeycomb chassis. A self contained cooling and exhaust system is designed and fitted to the 175 HP marine outboard engine. A specialised, high efficiency, transmission system is manufactured. The re-design of the field craft takes place in parallel and complementary to the development of a number of experimental test rigs.
The test rigs are designed to more accurately simulate the conditions experienced by an in-service skirt. Critical parameters in the development of these test rigs include comparative testing of candidate materials, correlation between test ng life and in- service craft life and relative costs of full scale and test rig experimentation
