Design and Analysis of the Control and Stability of a Blended Wing Body Aircraft


Future aircraft generations are required to provide higher performance and capacities with minimum cost and environmental impact. This calls for the design of revolutionary unconventional configurations, such as the Blended Wing Body (BWB), a new tailless aircraft which integrates the wing and the fuselage into a single lifting surface. It has been proven in previous works that this concept has an efficient economical performance and is a promising candidate for solving the current air traffic problems, despite its challenging control and stability features. KTH and DLR are investigating new ways to improve the aircraft conceptual design process in a multidisciplinary environment. The CEASIOM1 software for aircraft design is enhanced by implementing CPACS2, as an unified and more versatile software framework. After researching the latest developments in the BWB concept, a BWB aircraft baseline is designed and its aerodynamic behaviour and performance analyzed with a special emphasis on its stability and control features. The allocation and sizing of the control surfaces is then iterated over to find the optimum winglet size for minimum drag and radar detectability conditions. All in all, the satisfactory performance of the BWB concept and the usefulness of new design softwares were confirmed.

Aerodynamic analysis of a sustainable-energy sailplane using CEASIOM


This master thesis explains in detailed the process followed to make an aerodynamic analysis of the Warsaw University of Technology sailplane, The PW-5 Smyk, using a computerized environment developed as part of the SimSac project: CEASIOM. Throughout the document it is possible to find a step-by-step description on how the geometry should be defined in the CEASIOM’s stand alone module for Vortex Lattice Method solutions, Tornado. Besides, it provides a full description of the grid generation and the criteria used to determine if a mesh could be adequate for the specific purpose. At this point a mesh validation is  carried by comparing aerodynamic predictions with experimental measurements taken during the sailplane’s flight. Moreover, once the domain discretization and  calculation parameters have proven to be effective, a series of flight states are defined in Tornado with the aim of evaluate the airplane aerodynamics during different operating conditions. In fact, those computations were made following a special organization, which is required by SDSA in order to produce graphics as a solution found by the VLM code. At the end of the document the reader will find the presentation of the main plots achieved with CEASIOM and a short discussion on the implications that each of them has on the aircraft’s aerodynamics.
