About the Club

At The 3rd Dimension Aeromodelling Club, we engage ourselves to design and develop a span of models varying from Aerodynamic gliders to Autonomous Drones. We take up projects that unfold new areas related to aeromodelling, fluid mechanics, surveillance, advanced control systems, and auto-piloting algorithms, which sets new records for us.

The club was founded in 2013 by many aeromodelling enthusiasts who had a passion for defying gravity and soaring high by building UAVs from scratch. Over the years, our models were evolved significantly, our domain has expanded wide, and we have secured many podiums in different National Competitions and events.

Events Conducted

Workshop: Every year, we as a club organize a workshop for freshers which helps them understand the club, and also we include some hands-on sessions in the workshop through which the interested people get some sense of the actual work culture of the club. The workshop consists of two parts Aero and Tronix.

  • The Aero domain workshop involves introductory sessions to Aerodynamics, XFLR plane design, and design software like Solidworks and Catia for Design and analysis.
  • The Tronix domain of the workshop involves the Basics of programming, computer vision and stereo vision.

Projects

VTOL (Vertical Take-off and Landing)

We have analyzed and categorized existing VTOL solutions. Using this knowledge, we are designing our VTOL aircraft with significant payload objectives operations (point to point delivery/drop zone delivery) and surveillance operations (Search and rescue, Mapping, Land monitoring, filming/photography, photogrammetry etc.) We aim to achieve these objectives by making our aircraft efficient in hover, transition and horizontal flight combined.

VKAT (VON KARMAN AEROELASTIC TURBINE)

We designed a bladeless turbine using the principles of Fluid-Structure Interaction to extract clean energy from the Vortex-Induced Vibration of a bluff body in a low-velocity fluid (Von Karman Effect). We determined the ideal dimensions and working conditions of the bluff body by fluid simulation. We designed the energy extraction method and the final product with multiple smaller units to scale up the energy output.

MID-FLIGHT RECONFIGURATION DRONE

The main limitation of a drone is the flight time of the drone, i.e. the time taken for the power source (usually a battery) to reduce from its total capacity to the minimum required to land the drone without any damage. Any alteration or modification imparted in the drone is done, so keep in mind to solely increase this parameter called flight time. The drone that we have proposed here also has a similar goal. The proposed drone would be one that can be configured between a quadcopter(4 rotors), Hexacopter(6 rotors) and octocopter(8 rotors). These varying configurations would enable the drone to carry payloads of different capacities and accordingly increase flight time.

EKRANOPLAN

This project aims to make an aircraft that can take advantage of the ground effect, The phenomena by which aircraft tend to glide near the surface of the ground as their wings are more efficient, experiencing less drag (vortex drag) and increased lift (more significant; the pressure difference between the top and bottom of the wing. Because of their efficient flight, these aircraft can travel longer distances, faster, using less power. Their efficiency gradually increases with an increase in their weight till a certain point, allowing these aircraft to be much heavier and carry a greater payload than other aircraft. Our aircraft would be designed to fly over level surfaces like plains/water bodies, carrying increasing payloads as we test capabilities.

STATIONARY GLIDER

The project’s primary aim is to build a vertical Take-off and Landing (VTOL) craft specifically targeted for the military surveillance and transportation of medical goods. In this project, we seek to eliminate the standard limitations faced by existing UAVs and extend their usage boundaries. Unlike other VTOLs, this product is detachable and detachable, which helps in de-centralized manufacturing. This Product uses only a pair of motors which cut down the power consumption.

FIOT

The flying IoT project was developed to communicate with the drone using a web application and cloud computing. The web app was made using React framework and Bootstrap for styling. The waypoints for the drone to cover were selected using the web application. A cloud platform(AWS IoT) was used to communicate between the drone and the Web App, and all the real-time sensory data from the drone was stored in the cloud database. The microcontroller, ESP32, was used in the drone with a built-in wifi module to transfer all the data from the sensors directly into the cloud database.

VISUAL ODOMETRY

Odometry is an essential task for any ground or flying robot to know its location concerning the environment. In this project, we explored Classical Visual Odometry and odometry parameters prediction using visual sensors. The algorithm we used was based on the Optical Flow KLT algorithm and using RANSAC to optimize the extracted features. We were able to show that the algorithm works effectively on the small straight sequence of images. However, it deviated a bit while taking turns.

AKULA

This project is an autonomous robot fish that looks like a shark in form and motion and can carry a payload with inbuilt cameras for underwater surveillance through advanced image processing with controlled communication techniques.

What we did: We analyzed all the body features of a general fish, their movement inside water and also the size and positioning of various fins on their body and designed the mechanism for its action.

Induction Process

Generally, the induction process starts at the end of the academic year. It is around two months-long process where we teach and test the inductees right from the basics. We expect inductees to learn the basics during the induction process and perform well in the tests. Generally, the whole process is divided into 2 to 3 stages where the difficulty of the tasks increases as we move ahead. There may or may not be the interview rounds at the end of the 1st and 2nd stages. However, in the final stage, we have a Technical as well as an HR interview.

Note for the current 1st years for this academic year(2021-2022): We are launching Discord Community, where we will share all the resources to learn the basic stuff about aerodynamics. You can learn by doing some projects during your first year. The community will help you get started. If you do well during your first year, we may take you right before the official induction process. However, the induction process will be open for every 1st year(Whether he has joined Community or not).
