Modelling Air Quality in an Aircraft Passenger Cabin using Health Care Standards

The interest in aerosol contamination of aircraft passenger cabins has increased since the onset of the COVID-19 pandemic. Mathematical models have been developed to help describe how an aerosol behaves in a closed space…

A Model for Inhalation of Infectious Aerosol Contaminants in an Aircraft Passenger Cabin

Aerosol contamination of an aircraft cabin by infectious passengers is a concern of passengers, aircrew and the aviation industry. This may be especially important during a pandemic, such as COVID-19, where the full exte…

AERODYNAMIC PERFORMANCE ANALYSIS OF CO-FLOW JET AIRFOIL

The work in this paper aims to increase the maximum lift coefficient of the airfoil by implementing the co-flow jet concept on NACA 0018 airfoil and also to investigate the performance of co-flow jet (CFJ) airfoil.

Comparative study on performance accuracy of three probe and five probe flow analysers for wind tunnel testing

In the field of inviscid fluid flow studies, the theoretical concept has to be developed even more. In order to make it possible, it is very important to supplement the concepts with strong experimental results.

Identify aerodynamic derivatives of the airplane attitude channel using a spiking neural network

The paper proposes a method for identifying aerodynamic coefficient derivatives of aircraft attitude channel using spiking neural network (SNN) and Gauss-Newton algorithm based on data obtained from actual flights.

Experimental and Computational Evaluation of Five Hole Five Probe Flow Analyzer for Subsonic Wind Calibration

It is very essential to predict the flow and its related parameters to understand real life fluid flow. The real-life fluid problems are studied with wind tunnels which gives very efficient results in practice.

Performance Characteristics Design of Pulsed Plasma Thrusters for Drag Counter-Reacting

Determining the performance characteristics of off the shelf pulsed plasma thrusters to enhance the life time of low earth orbiting platforms was investigated theoretically.

A New Method for the Prediction of the Downwash Angle Gradient

A new method for the prediction of the downwash angle gradient due to aircraft wings across the span of an aft horizontal tail in the incompressible regime is presented.

Design and Realization of an Unmanned Aerial Rotorcraft Vehicle Using Pressurized Inflatable Structure

Unmanned aerial rotorcraft vehicles have many military, commercial and civil applications. There is a necessity to advance the performance on several ranges of rotorcraft for using these vehicles successfully in the expa…

Aerodynamic Design and Exploration of a Blended Wing Body Aircraft at Subsonic Speed

Blended Wing Body (BWB) is a novel aircraft concept which provides many different aerodynamic benefits over conventional aircrafts design.

Experimental investigation of a new spiral wingtip

Experiments on the relative merits and demerits of slotted wingtips mimicking a bird’s primary feathers have been performed. The real emargination length of feather tips, their flexibility and curved shapes during cruise…

Low Reynolds Number Numerical Simulation of the Aerodynamic Coefficients of a 3D Wing

A low Reynolds number, three-dimensional CFD analysis is carried out for a finite flat plate wing using the commercial CFD code STAR CCM+.

Blended Wing Body Propulsion System Design

This research paper focuses on the optimization of the propulsion system of a blended wing body design. Two different aspects of the design, the engine placement and count, and the engine itself, are investigated.

Wingtip Vortex Alleviation Using a Reverse Delta Type Add-on Device

The result of interactions of a wingtip vortex of a half-span wing and vortices generated by a slender reverse delta type add-on device were studied using Particle Image Velocimetry in a closed-loop low-speed wind tunnel…

Impact of a Reverse Delta Type Add-on Device on the Flap-tip Vortex of a Wing

The effect of interactions of vortices produced by an outboard flap-tip of a half-span wing (NACA 23012 in landing configuration) and a slender reverse delta type add-on device, placed in the proximity of the outboard fl…
