## Book 1.1

A textbook on the use of fluids in mechanical engineering

by

Ivor Bittle

**This picture epitomises the whole objective of this book. The received wisdom is that fans when used to create an air cushion are noisy in the extreme and grossly inefficient. I thought that this was wrong. I used the well-known knowledge that is available to anyone to design and build this model ferry that rides on an air cushion. It is so quiet that I cannot monitor the lift fan by listening to it and where the very best full-sized air cushion needs 15 kilowatts to lift a ton the model requires 7 kilowatts per ton. As a bonus it produces no bow wave. It is fast. It says that there is something to be gained by the use of science and practical knowledge in mechanical engineering.**
