Insight into my final year dissertation project so far!   Title : Investigation of dragonfly wing aerodynamics through CFD and wind tunnel testing, for UAV application.   Background - Many research papers have shown that dragonfly wings are more efficient in glide than traditional airfoils due to their corrugated nature.   Desing & Analysis - To investigate this, I designed a fixture that allows me to use the wind tunnel for analysis. I also began to conduct CFD analysis on the wing at varying angles, to validate the process.   Testing - The model is now being tested in the wind tunnel, at speeds of 1.4m/s - 14m/s.

Discovery. That’s one thing that keeps Research Assistant Professor Nathan Webb inspired. Along with others in the Gas Dynamics and Turbulence Lab, he is examining the ability of plasma actuators to vector the thrust from a fixed-geometry jet. Read more about the project – plus insightful advice for prospective graduate students – in this edition of our faculty spotlight (link in comments). #aerospace #AerospaceResearch #GasDynamics #GraduateSchool #GraduateStudent #GraduateStudentAdvice #GraduateStudentLife #GraduateStudents #JetResearch #PlasmaActuator #PlasmaActuators #ResearchLife Department of Mechanical and Aerospace Engineering at The Ohio State University

Excited to share the publication: "Combustion Instabilities in Complex Chamber Geometries of Solid Propellant Rocket Motors", co-authored with Juan M. Tizón. This work, based on my BSc final project, presents a 2D acoustic FVM solver for unstructured meshes of solid rocket engine geometries and a model for analyzing combustion instabilities in solid rocket motors. It was developed during my time as a student researcher at the Propulsion & Fluid Mechanics Department of Universidad Politécnica de Madrid, where the team continues to advance this line of research.

I just attended the International Conference on IC Engine, Propulsion and Combustion hosted by Graphic Era Deemed to be University, presenting the paper "Comparative Study of Different Injector Configurations in a Hypergolic Bipropellant Thruster". This paper was part of my Master's thesis at TU Delft | Aerospace Engineering, which I worked on with Dr. B.V.S. Jyoti and Prakhar Jindal under the #Greenlam project funded by #HorizonEurope. In the paper we looked at three different injectors, their effect on the combustion characteristics in a HTP-kerosene thruster simulation and challenges attributed to the numerical modelling of droplet-droplet interaction.

#Design #Simulation #DLR #Mechanical Design of Experiment to observe the vibration index by placing tuning masses on the helicopter rotor blade Objective: Minimizing the vibration index which is responsible for vibration at the rotor hub at Low-speed forward decent flight condition Design Variables: Tuning masses placed on rotor blade[kg] - 0.01kg - 0.23kg(10% of blade weight) Spanwise location of the blade[m]- 0.46m - 2m(22% of span length) Description: While active technologies reduce helicopter rotor vibration, they are also complex and expensive. Helicopter vibration in forward flight is predominantly produced by the main rotor itself. The passive method of placing lumped masses on the rotor blade can significantly reduce rotor vibration. This was the premise of my Master's thesis at German Aerospace Center (DLR) Braunschweig. I am glad that, it led to a paper at the European Rotorcraft Forum in Marseilles. The figure below shows the impact of lumped masses on the vibration index of a rotor blade. Vibration index when varying mass with 0.01 kg increment at varying spanwise locations on the elastic axis of the rotor blade. The maximum Vibration Index is observed at about 0.8m or 40% span of the blade while the least Vibration Index is observed at about 1.84m or 92% span. I would like to thank my mentor Rohin Majeti, PhD for the guidance and German Aerospace Center (DLR) Braunshcweig for their support. #DesignofExperiments #DLR #Design #Simulation #MechanicalEngineering #Jobsearch #Optimization #Stressanalysis #ScientificInstrumentation #Germany #Worldwide #Forceanalysis #Ansys #Autodeskinventor #Fusion360 #FreeCAD #RCE #EAHJena #Brunschweig

Alhamdulillah. my another journal articles, "Improve the aerodynamics performance of the wing using Shark Denticles" has been published Volume 11 Issue 1 2024 issue for publication in the International Journal of recent Engineering science (IJRES) Special thanks to Masum Hossain Paper ID: IJRES-V11I1P106 DOI: https://lnkd.in/guJ9JyiU

Our first activity in LPU of B.Tech Aerospace Engineering Recorded time with obstacle: 19.97 Approx time without the obstacle: 21.74 **Parachute-Making Workshop: An Exploration of Creativity and Engineering** Our inaugural parachute-making activity represented a thrilling experience, creativity, collaboration, and practical learning. Students united to design and construct functional parachutes using basic materials. The objective was to develop a parachute capable of safely delivering a small payload from a considerable height. Throughout the project, we examined the concepts of aerodynamics, drag, and material science, while welcoming trial and error to enhance our designs. The session not only improved our problem-solving capabilities but also nurtured a spirit of teamwork and innovation. It served as an engaging and instructive approach to applying theoretical knowledge to a practical challenge.

I am delighted to share that our recent research article titled “Role of carbide grit size and in-flight particle parameters on the microstructure, phases, and nanoscale properties of HVOF sprayed WC-12Co coatings” has been published in the Journal "Surface and Coatings Technology". In this work, we have captured the effect of particle temperature on in-flight reactions and phase composition of the as-sprayed coatings while keeping the particle velocity nearly constant and vice-versa. The key aspects of this current investigation are:     I.       Understanding the effect of either particle temperature or velocity on phase composition, while keeping the other nearly constant.    II.       The effect of cooling rate and carbide dissolution on amorphization of binder matrix.  III.       The effect of carbide size on dissolution kinetics and decarburization mechanisms.  IV.       The effect of dissolution and decarburization on mechanical properties of binder and carbide phase. I thank my PhD supervisor Professor Partha Pratim Bandyopadhyay for his constant support and encouragement. I would also like to thank the Aeronautics Research and Development Board (AR&DB), India for funding this project and the VTC Surface Technologies Visakhapatnam, A.P, INDIA for letting us use the HVOF coating facility.
