Processus de conception multidisciplinaire dédié aux configurations Blended Wing Body

The Blended Wing Body (BWB) configuration seems to be one of the most promising concepts to replace the current passenger transport aircrafts with substantial improvement of their performance and reduction of their environmental footprint. However the expected gains still need to be precisely evaluated with airplanes to design. BWB concept is a highly coupled system because every sizing discipline is connected to a single system: the wing. This paper presents the multidisciplinary design analysis and optimization process of a blended wing body and its application to a long-haul commercial transport mission

CONCEPTUAL DESIGN STUDIES OF UNCONVENTIONAL CONFIGURATIONS

The potential of unconventional configurations to reduce the fuel consumption of future aircraft is investigated in the European Clean Sky 2 (ITD Airframe) ONERA-DLR project NACOR (New Aircraft Concepts Research - Call for Core Partners Wave 1). Two design missions are considered: a short/medium range mission (SMR) based on the requirements of an Airbus A320, and a business jet (BJ) mission. In this paper, an overview of the activities considering the conceptual aircraft design phase including initial high fidelity studies is provided
