Abstract
This paper describes a technique for determining the components of vehicle drag based on the well established coastdown method. Using on board anemometers to continuously measure the ambient wind input and a sophisticated analysis procedure the method makes it possible for small changes in vehicle configuration to be analysed. The experimental technique and analytical approach are described and discussed in detail, and the accuracy achieved and that expected in further tests is highlighted.
