Conceptual Design of Blended Wing Body Airliners Within a Semi-automated Design Framework

Blended wing body aircraft represent a paradigm shift in jet transport aircraft design. Stepping away from the conventional tube-and-wing philosophy, they promise benefits over existing or future conventional aircraft. The most significant challenge with the concept is the increased coupling between aircraft design disciplines that has...

Rudder Incorporated Winglet Design for Blended Wing Body Aircraft

Concern about the environmental footprint of aviation has re-sparked the interest in unconventional configurations, such as the blended wing body aircraft, BWB. While most research studies recognize the potential of the hybrid-body, they also list a number of challenges. Amongst these challenges is the need for adequate lateral-directional...

Effectiveness of Thrust Vectoring Control for Longitudinal Trim of a Blended Wing Body Aircraft

The application of thrust vectoring on civil transport aircraft has only been studied by a few individuals. Quantified investigations need to be carried out to search for the potential benefits of the application of thrust vectoring control on a civil transport aircraft. Blended Wing Body configuration is a novel aircraft concept. Due to the...

Design of Inlet for Boundary Layer Ingestion in a Blended Wing Body Aircraft

Boundary Layer Ingestion (BLI) is a concept in which the fuselage boundary layer is ingested by the engine to produce benefits like improved fuel efficiency, reduction of ram drag and lower structural weight of the configuration. Blended Wing Body (BWB) concept has been researched on and studied in various forms over the years as an efficient...

The Oval Fuselage: A New Structural Design Concept for Blended Wing Body Cabins

Faced with the decreasing fossil fuel reserves and the need to decrease its environmental footprint, the aviation industry is searching for alternative fuels and more fuel efficient engines and aircraft.

Multidisciplinary Design Optimization in the Conceptual Design Phase: Creating a Conceptual Design of the Blended Wing-Body with the BLISS Optimization Strategy

Traditionally, the aircraft design process is divided into three phases: conceptual, preliminary and detailed design. In each subsequent phase, the fidelity of the analysis tools increases and more and more details of the design geometry are frozen. In each phase a number of design variants is generated, fully analyzing them with the tools...
