Patent GB-1896-3657
Aircraft based around a central fan. Takes off more or less like a helicopter, then adjusted for horizontal movement.
The engine sits in the car and the fan cools it:
The motor indicated at C is a four cylinder four stroke cycle petroleum motor, of course other types of motor or power could be employed, but I prefer a petroleum motor for this purpose.
In small machines of this description it will be possible to do without a jacket altogether, owing to the enormous blast of air driven downward on to the motor by the fan. In any case only a very small quantity of water need be carried, and this will be sufficiently cooled in the tubular frame G G1 by the before mentioned blast of air.
