Synthesis of an Aircraft Featuring a Ducted-Fan Propulsive Empennage

A study is done to investigate the feasibility of the conceptual design of the Delft University Unconventional Configuration (DUUC), an aircraft featuring a ducted-fan propulsive empennage. This research is focused on ducted-fan performance analysis and aircraft longitudinal static stability and balance estimation. The aircraft design Initiator...

Business Jet Design Using Laminar Flow

For conceptual aircraft design to include accurate laminar flow prediction, a link between modern computational tools to determine laminar-to-turbulent boundary layer transition and fast sizing methods is required. For swept wings, it is crucial to include the highly unstable three-dimensional crossflow component of the boundary layer. These...

Conceptual Design of High Subsonic Prandtl Planes

The increasing airtraffic demands on aircraft capacity, sustainability and profitability, require the investigation of unconventional aircraft configurations with high aerodynamic efficiency, as the commonly applied fuselage-wing-tail configuration shows to reach an optimum in that respect which cannot be further improved using current...

Modelling the Propeller Slipstream Effect on the Longitudinal Stability and Control

As the aviation industry continues to strive for improvements in fuel efficiency throughout the entire aircraft design, interest has been renewed in propeller engines. New research into advanced turboprop engines, so-called open rotor engines, seems promising as they combine the inherent high propulsive efficiency of ordinary turboprop engines,...

Landing gear design in an automated design environment

The design of the landing gear is one of the prime aspects of aircraft design. Literature describes the design process thoroughly, however the integration of these design methods within an automated design framework has had little focus in literature. Landing gear design includes different engineering disciplines including structures, weights,...

Synthesis of Novel Aircraft Concepts for Future Air Travel

In the last 60 years many new technologies have entered the aerospace industry, but the overall aircraft design remained virtually unchanged. If we compare an aircraft built in the 1960's with the latest generation, they look strikingly similar. Only small evolutionary changes entered the commercial aircraft market. A lot of these changes are...
