Recent advances in radio controlled model testing
At 2010 Chesapeake Powerboat Symposium, United States.
19 - 20 Mar 2010.
Self propelled models under radio control have been used for many years to assess the manoeuvring and handling of ships. The limitations for testing small, fast craft have been linked to the low model weight required and the ability to install enough power, as well as the cost of modelling. Engineers at the Wolfson Unit have developed test methods appropriate for studying the particular problems of small craft, with small budgets, but model speed has always been limited by the available components.
Recent advances in motor and battery technology, the availability of model water jet drives, and developments in small data logging and GPS systems have enabled cost effective modelling of very fast craft. Their handling characteristics can now be assessed accurately at an early stage of the design. This helps to ensure a successful boat, determine the acceptable boundaries of the design, or modify it to eliminate any problems found.
