Aerodynamics plays a crucial role in cycling, as most of the resistance a cyclist must overcome is drag. The aerodynamic performance of cyclists has been investigated in multiple experiments all around the world to understand the aerodynamics and reduce the drag. To improve the cycling aerodynamic knowledge and understanding, a Generic Cyclist Model (GCM) is created. The original Generic Cyclist Model is placed in a time trial with an asymmetrical leg position. This work broadens the aerodynamic knowledge by investigating the GCM with a symmetrical leg position. The aerodynamic sensitivity of the Symmetric Generic Cyclist Model and the differences compared to the Asymmetric GCM are analysed based on the influences of the leg position, Reynolds number variation, crosswind and the addition of flow control devices.
The wind tunnel experiment used force balances and 3D particle image velocimetry to analyse the aerodynamic performances; drag area, and flow fields of the cyclist.
The experiment indicates that the leg position has a significant influence on the aerodynamic performance, with the symmetric leg position yielding a lower drag area. This indicates that the legs have a great influence on the overall aerodynamic performance of the cyclist. The velocity and vorticity flow fields show a leg wake reduction and weakened repositioned vortices. The Reynolds number variations and the introduction of crosswind have a great influence on the drag area and flow fields of the cyclist. Showing that high velocities and crosswind are beneficial for drag area reductions for the Symmetrical GCM. Furthermore, the addition of flow control devices is beneficial for drag area reduction.

The aim of this Design Synthesis Exercise was to design a floating large-scale wind farm of 1 GW in deep water using an Airborne Wind Energy System (AWES) that is cost-competitive, largely recyclable and uses less material than conventional wind turbines. By exploring the project foundation, carrying out an iterative single-system design process, and delving into the farm layout and management, this project assesses the feasibility of this novel concept. This report proposes an initial design with the resources currently available to the team while highlighting the next steps that need to be taken in order to pursue further design iterations, prototyping, and testing of this concept. This initial design, the tool developed to carry out the sizing, and a detailed reflection on the limitations of this design process and concept could be stated as the main contribution of this project to the field of airborne wind energy.
