A Review of Engineering Developments in Helicopter Design
The Aeronautical Journal, 1969One of the most interesting aspects of the aeronautical endeavours of Henson and Stringfellow was their awareness of the impact of the aeroplane as part of an overall transport system. It is all too easy in the field of aeronautical engineering to become mesmerised by the engineering intricacies of what one is doing and so fail to see the vehicle as ...
