A 250 PASSENGER PRANDTLPLANE TRANSPORT AIRCRAFT PRELIMINARY DESIGN

Aldo Frediani, Emanuele Rizzo, Claudio Bottoni

Abstract


Civil transport aircraft of the future are requested to improve their performances to meet the new requirements for the aeronautics of the next decades, with a significant reduction of Direct Operating Costs, less noxious emissions and noise, high performances. The problem of reducing Direct Operative Costs will not be satisfied without a significant improvement of aircraft efficiency, that can be hardly obtained by an optimisation of conventional aircraft. Hence, new non conventional aircraft configurations are becoming more and more interesting. Many configurations have been proposed recently and a brief summary is given here on this subject. The present paper shows a preliminary design of an unconventional aircraft, named PrandtlPlane. The configuration is defined in order to locate a large amount of cargo together with passengers and to reduce the induced drag. The fuselage is wider and shorter than a conventional one, to accomodate 250-300 passengers, together with a large cargo capacity. The paper deals with different aspects of the design as, for example: the architectural solutions, the allocation of passengers and cargo, the procedures for loading and unloading, the structural solution of the fuselage (including main undercarriage), the aerodynamic design at cruise speed and low speed, with the high lift devices extracted.
