Analysis of potential wake vortex encounters at a major European airport

Frank Holzäpfel

In this study, 12 potential wake vortex encounters that were reported at a major European airport have been investigated. Because almost all encounters occurred in ground…

Modeling of CPACS-based fuselage structures using Python

Jan-Niclas Walther, Michael Petsch, Dieter Kohlgrüber

The purpose of this paper is to present some of the key achievements. At DLR, a sophisticated interdisciplinary aircraft design process is being developed, using the CPACS data…

Common computational model for coupling panel method with finite element method

Tomasz Goetzendorf-Grabowski, Jacek Mieloszyk

Conceptual and preliminary aircraft concepts are getting mature earlier in the design process, than ever before. To achieve that advanced level of maturity, multiple…

Aerodynamics analysis of the main rotor influence on the static stability of the gyroplane

Marcin Figat

This paper aims to present the results of aerodynamic calculation of impact the main rotor on the fuselage and the tail of a light gyroplane. This kind of vehicle is a type of…

Plasma-based flow control for low-pressure turbines at low-Reynolds-number

David S. Martínez, Elisa Pescini, Maria Grazia De Giorgi, Antonio Ficarella

Reynolds number in small-size low-pressure turbines (LPT) can drop below 2.5 · 10⁴ at high altitude cruise, which in turn can lead to laminar boundary layer separation on the…

Turbulence modelling techniques for aeroelastic problems: results and comments from the Second AIAA Aeroelastic Prediction Workshop

Marcello Righi

The quality of aeroelastic predictions strongly depends on the quality of aerodynamic predictions. At the boundary of a typical flight envelope, special flow conditions may arise…

The effect of gusts on aircraft wake vortices

Anton Stephan, Frank Holzäpfel, Stefan Zholtovski

This study aims to investigate the effect of gusts on aircraft wake vortices. Aircraft wake vortices present a potential risk to following aircraft, particularly during final…

The civil use of small unmanned aerial systems (sUASs): operational and safety challenges

Laura Novaro Mascarello, Fulvia Quagliotti

In the past decades, both civil and military applications of small unmanned aerial systems (sUASs) have been on the rise. The sUASs guarantee the performance of dangerous, dull…

Fluidic actuators for separation control at the engine/wing junction

Philipp Schloesser, Michael Meyer, Martin Schueller, Perez Weigel, Matthias Bauer

The area behind the engine/wing junction of conventional civil aircraft configurations with underwing-mounted turbofans is susceptible to local flow separation at high angles of…

On-design exergy analysis of a combustor for a turbojet engine: a parametric study

Ahmet Topal, Onder Turan

The purpose of this study is to perform an exergy analysis of a turbojet engine combustor at different cycle parameters.

Active flow control concepts and application opportunities

Heribert Bieler

Aerodynamics drives the aircraft performance and, thus, influences fuel consumption and environmental compatibility. Further, optimization of aerodynamic shapes is an ongoing…

Research on light aircraft spinning properties

Ewa Cichocka

The paper focuses on the evaluation of a light aircraft spin. The main purpose of this paper is to achieve reliable mathematical models of aircraft motion beyond stall conditions…
