The Aerodynamic Design Philosophy of the Handley Page Jetstream: A detailed account of the aerodynamic considerations involved in the evolution of a new executive or feederliner aircraft

THE relation between aerodynamics and the design of an aircraft and its power plant is unique in engineering; it is only in aircraft design that good aerodynamics is a prerequisite for success. Of course the structure must be good (though this is true of ships or bridges) and so must the motor (but this also applies to motor cars and railway engines) and the electrics must be efficient (and so must they be for a television set); and so on through many other technologies. But the start, and the heart, of the design is aerodynamics, the one feature that distinguishes aeroplanes from all other forms of transport. At the present time Handley Page Limited is engaged in the production of a new turboprop business cum feeder‐liner aeroplane the H.P. 137 Jetstream, which made its first flight on August 18.
