APIAN-INF: an aerodynamic and aeroacoustic investigation of pylon-interaction effects for pusher propellers

Advanced propellers promise significant fuel-burn savings compared to turbofans. When installed on the fuselage in a pusher configuration, the propeller interacts with the wake of the supporting pylon. This paper presents an experimental analysis of the aerodynamic and aeroacoustic characteristics of this pylon–propeller interaction. An isolated...

Design and Analysis of an Installed Pusher Propeller with Boundary Layer Inflow

Boundary Layer Ingestion is an integrated propulsion concept in which a propulsor operates in boundary layer flow instead of the free streamflow with the goal to reduce the fuel flow for a given operating condition. The objective of this thesis is to obtain a better understanding of the power benefit of an installed pusher propeller at the aft...

Empennage Wake Filling using Steady Chord-wise Blowing for Propulsive Fuselage Concepts

It is the need of the hour to focus research and development towards curbing emissions due to the growing aviation industry. Employing boundary layer Ingesting(BLI) propellers for development of propulsive fuselage concept(PFC) aircraft while utilizing hydrogen as an alternative energy source, is the idea behind project APPU(Advanced Propulsion...

Parametric Modeling and Optimization of Advanced Propellers for Next-Generation Aircraft

As traditional fossil fuels become scarcer and more attention is given to environmental impact of the combustion of fossil fuels, for next-generation aircraft, the focus of development will mainly be on reducing fuel consumption. Open rotor engines have the advantage over conventional turbofans that they are expected to perform 25% to 30% better...

Aerodynamic design for a pusher propeller spinner

The present work has placed particular importance on the spinner aerodynamic design in order to enhance the performance of a pusher propeller configuration. The research has been focused on the aerodynamic shaping of the spinner in order to provide a better understanding of the nacelle-blade-spinner interaction in cruise conditions. The set of...

From Trash to Treasure: Design of a gripper for automated sorting of mixed aluminium scrap to create added value

Reukema is the biggest non-ferrous trader in the Netherlands. They want to investigate the possibility of sorting aluminium in a robotic system. Aluminium is one of the most used materials worldwide. Demands for aluminium are ever increasing. Recycling scrap is needed to keep up with the demand. An important step in the recycling process is the...
