Abstract : Future Large Aircraft is a generic term used to describe a future medium sized tactical transport aircraft and derivatives for other roles. Its design will utilise modern technology to provide a replacement for airforces' mixed fleets of Hercules, Transall and a multitude of other aircraft used in tanking, maritime patrol, and other such roles. Studies conducted so far have shown the powerplant to be the key technology for a new military transport aircraft. Relative to the Hercules and Transall, large gains in capability, and savings in cost, are available with modern powerplants. The influence of powerplant selection is so critical that it is likely to drive the mission capability that can be economically provided. This paper identifies the main design requirements for this type of aircraft. The benefits of modern technology when applied to both airframe and engine in a military transport are discussed. Turboprop, turbofan, and propfan engines are compared, and the benefits and availability of civil engines reviewed. Finally, several different aircraft solutions are presented, covering the range of possible powerplants, and their characteristics compared.
