Interest in powered flight on Mars has been growing in recent years, and as such new developments are being made in determining the effects the Martian atmosphere has on the flow physics and performance, specifically with regards to similarity parameters: the Reynolds number & the Mach number. This paper aimed to investigate whether the...

Leading-edge inflatable (LEI) kites use a pressurized tubular frame to structurally support a single skin membrane canopy. The presence of the tubes on the pressure side of the wing leads to characteristic flow phenomena for this type of kite. In this paper, we present steady-state Reynolds-Averaged Navier-Stokes (RANS) simulations for a LEI...

Recent trends in aviation highlight the ever-increasing need for fuel economy and sustainability. Active morphing technology can offer significant benefits over conventional wing designs. Inspired by nature, smart morphing technologies enable the aircraft of tomorrow to sense their environment and adapt the shape of their wings in-flight to...

A new aircraft configuration, the Delft University Unconventional Configuration (DUUC), was recently invented by the Flight Performance and Propulsion group at TU Delft. As a solution to the concerns regarding the environmental and health impact due to increasing demand of air travel. The DUUC has a characteristic feature which consist of two...

Propellers were the first means of powered propulsion for aircraft. However the development of propellers stalled due to the growing interest in jet propulsion. Due to the growing interest in more fuel efficient and environmentally responsible aviation, propeller research is currently seeing a resurgence. <br/><br/>Wingtip-mounted propellers are...

To reduce the environmental impact of aviation, new aircraft configurations are investigated. One of these researches is the PARSIFAL project, that investigates an efficient box-wing aircraft for passenger transport. In previous work, an engine sizing tool is developed to design the engines of the PARSIFAL aircraft. The tool is developed as part...

Wingtip-mounted propellers have the ability to enhance the propeller-wing system performance. For inboard-up rotating tractor propellers, the swirl in the propeller slipstream can be used on the wing to reduce the influence of the wingtip vortex, decreasing drag. Furthermore, lift is enhanced by increasing dynamic pressure and angle of attack...

A low-speed aerodynamic analysis on the conventional NACA ram-air inlet of the Airbus A320 with a new closure flap was conducted. The conventional closure flap mechanism inside the NACA ram-air inlet is replaced by a morphing plate design. Steady-state Reynolds-Averaged Navier-Stokes (RANS) based Computational Fluid Dynamics (CFD) simulations...

With the goal of decreasing the environmental impact of aircraft, ducted propellers emerge as an efficient propulsive alternative. Ducts are able to increase the thrust to power ratio of a propeller system by both producing thrust and/or lowering tip losses of propellers. In this thesis, RANS CFD simulations were used to analyse the possible...

A study of the aerodynamic performance of a NACA 643418 airfoil with trailing edge serrations is presented. For the prediction of the changes in lift due to the serration installation, an empirical law is derived that can be extended to typical cambered airfoils for wind turbine applications. The law is deduced from 2D and 3D Reynolds‐averaged...
