The purpose of this research is to develop a MATLAB model which can calculate the aerodynamics, such as lift, drag, and pressure, on an airfoil as it changes shape. This model needs to be computationally efficient and should have reasonable accuracy. A constant strength doublet panel code, which takes thickness and camber distribution as inputs, is used to model the aerodynamics. This code has ...

According to Slotnick et al. (2014), in 2025, air transport will contribute 1.5 billion tonnes of CO2 emissions annually. Of course, there are many other fluid dynamic engineering systems and processes that contribute to environmentally damaging emissions. Hence, it is critical to study aerodynamics with the view to creating more energy-efficient systems. Broadly speaking, the design engineer h...

We propose a novel estimation method of the rotational velocity of a flying ball as well as its position and translational velocity via aerodynamics model by measuring the ball trajectory using the middle speed cameras for table tennis system. The aerodynamics model is complex nonlinear and the measured data of the ball trajectory has quantization errors because the size of the ball is very sma...

This paper presents a new framework for the coupled optimization of aero-structural systems. The framework permits the use of high-fidelity modeling of both the aerodynamics and the structures and represents our first step in an effort towards the development of a high-fidelity multidisciplinary optimization capability. The approach is based on efficient analysis methodologies for the solution ...

Rotary wing aerodynamics represents a widely investigated topic due to this discipline’s large number of applications in several fields engineering and physics [...]

In this work we analyse the potential for a warp drive spacetime to develop instabilities due presence of quantum matter. Particularly, look points infinite blueshift (which are analogous black hole inner horizon, known its semiclassical instability), and categorise them through behaviour geodesics in their vicinity. We find that warp-drive bubbles dimension 2+1 or higher fact likely be stable,...

This paper presents a recently developed computational tool for aeroelastic analysis of aircraft performance. The computational tool couples a vortex-lattice code, Vorview, with an aeroelastic model that computes wing structural deflections under a combined coupled bending-torsion motion. The aeroelastic model of the wing structure is based on a one-dimensional structural dynamic theory using s...

This research investigated the relationship between athlete aerodynamics (based on peak frontal area during recovery phase) and finishing position for athletes in the 100m5000m wheelchair Athletics events. A retrospective analysis was performed on T54 classified male and female finalists (n=86) at the 2016 Rio Paralympic Games. Medalling female athletes more consistently favoured an aerodynamic...
