Aerodynamic Design of a Flying V Aircraft in Transonic Conditions

The Flying V is a long-range, flying-wing aircraft where payload and fuel both reside in a V-shaped, crescent wing with large winglets that double as vertical tail planes. The objective of this study is to maximize the lift-to-drag (𝐿/𝐷) ratio of the Flying V in cruise conditions, i.e. 𝐶𝐿 = 0.26, 𝑀 = 0.85...

Propeller Slipstream Effects on Longitudinal Static Stability: Effect of the Rethorst Correction at the Horizontal Stabilizer

The potential for a correction by Rethorst for Vortex Lattice Methods (VLMs) exists to improve Longitudinal Static Stability predictions when applying the Rethorst correction to a slipstream engulfed horizontal stabilizer. The Rethorst correction has already proven to result in accurate lift predictions in VLMs for an isolated wing in a...

Performance of a Single-Aisle Aircraft with Auxiliary Propulsion and Power Unit

The aviation industry has grown at a steady rate of 5% per year over the past decades and is projected to continue this growth over the coming years. In sharp contrast stands the increasing concern with the reduction of the environmental impact of flying in the short term. To this end, a fuselage boundary layer ingesting propulsor powered using...

Fuel Tank Integration for Hydrogen Airliners

Zero-carbon-dioxide-emitting hydrogen-powered aircraft have, in recent decades, come back on the stage as promising protagonists in the fight against global warming. Nevertheless, most recent studies agree that hydrogen aircraft would underperform their kerosene counterparts in terms of operative empty mass and specific energy consumption. The...

Conceptual Design of Hydrogen Fuel Cell Aircraft: Flying on hydrogen for a more sustainable future

The demand for air travel is increasing as more people gain access to commercial aviation. As the current generation of aircraft makes use of fossil fuel combustion, this growth results in an increase in the global emissions. This is at odds with the worldwide efforts of reducing the adverse effects of climate change. Therefore, advanced...

An Assessment of a Regional Turboprop Featuring Wingtip-Mounted Propellers: Design Integration Coupling Propeller-Wing Aerodynamics and Structural Wing Weight

The current focus in the aviation industry for more sustainable designs, could mean the revive of propeller propulsion, due to their relative high propulsion efficiency compared to jets. In addition, the application of wingtip-mounted propellers installed in tractor configuration can be used as tip-vortex attenuating devices, reducing the wing...

A Novel Aircraft Market Assessment Model under Flexible Passenger Demand

Due to strong demand for air travel before the COVID-19 pandemic, major airports were constrained in capacity and this issue was expected to worsen in the coming decades. Novel aircraft (concepts) could help to alleviate these capacity constraints. However, the market competitiveness and impact of novel aircraft is often challenging to assess,...
