The de Havilland DH 121 Trident: Description of the Historical Background, Configuration, Aerodynamic and Structural Features, Testing and Systems

Abstract

THE earliest origins of the Trident may be said to lie as far back as 1944 when we made some preliminary studies of the ways in which the newly arrived turbojet engine could be exploited for civil use. Our first thoughts were that the high consumption of the early centrifugal engines would restrict their practical use to short and medium hauls, and we envisaged a three‐engined aircraft with tail booms and engines buried in the rear of a short fuselage somewhat on the lines of a scaled‐up Vampire, capable of carrying 20 passengers over stages up to 750 statute miles and operating from 3,500—4,000 ft. runways.
