TechTatva’18—Airborne

Quadcombat
Devyani Mehta

Quadcombat was a two-day workshop which aimed to teach students how to make their very own drone. It was beneficial for amateur aeronautics enthusiasts, as no prior knowledge of drones was required to participate. The event took place on 3rd and 4th October and witnessed the involvement of a small group of eager participants.

The first day’s session lasted for two and a half hours. It began with a presentation that illustrated the basic working principles of a drone. The session then proceeded with hands-on work, where the participants were required to frame the basic model of the drone, which included its mainframe, propellers, and the motherboard. Participants found the process of soldering components together particularly interesting and showed active participation throughout the session.

On the second day, the participants were required to bring their unfinished drones and join the remaining parts to the mainframe. This task seemed to be more challenging than the first day’s task, but the participants appeared to enjoy completing it. “Aeronautics has always fascinated me. I had a lot of options but I decided to start from the basics,” said Shraddha, a participant, explaining her motivation to participate in a fundamental drone-making workshop, before moving on to more competitive events like drone-racing.

Although there was a slight delay in starting the event, it was compensated for by the seamless organisation. The participants were pleased to be a part of the event as they got the opportunity to learn something that they were passionate about. According to Shahnaz, the Event Head, “The idea of the event was to make it fun for the participants. I was satisfied with the turnout and the engagement of the freshers. It makes me happy to see them enjoy what I enjoy.”

Airborne conducted the first edition of its new event, Let’s Blimp, on day two and three of TechTatva. The event aimed at educating students about the working of lighter-than-air vehicles. Participants learned to construct their own blimps and engaged in a flight test. Initially, they learnt the craft of blimp-making in a series of pre-TechTatva workshops, and eventually put their knowledge to the test in a two-day competition.

We couldn’t publicise the event as much as we wanted to, that was an issue,” said Tanmay Raut, the Event Head, with regard to the lack of participation at the event. However, the avid learners who did turn up made the most out of this enlightening workshop. With constant help from the organisers, participants assembled the blimp with cardboard and glue, modelling it against a balloon. At the end of an exhausting first day, most contestants were able to shape a blimp with their balloons while some still struggled with the technique of folding the cardboard. A slight change in the procedure allowed the event to be conducted as a workshop rather than a competition which proved to be beneficial for the participants.

After a thorough session on modelling, the participants tested their creations in the second round. They released their blimps from the third floor of AB-5 to check their endurance and range, in a brief flight test. Like any other flight mission, Let’s Blimp had its share of failures and successes. In any case, this unique event was definitely successful in sparking curiosity about aeronautics in all those who attended it.


Hover Race

Airborne’s Hover Race took place on 3rd, 4th, and 5th October in AB-5 207. The event began with an introductory video on the basic working and design of hovercraft. After this, the organisers and the Event Heads distributed the basic logistics and required equipment to the participants.

Round One introduced students to the working principle of a hovercraft. Participants were also given directions on how to build the hovercraft by themselves. The round concluded with a few instructions about the judging criteria. Over the course of the second day, contestants finalised their designs and built their hovercraft.

In the final round, which took place on 5th October, a change of rules took place. It was decided that time trials would be the only basis for judgement, instead of the previous plan of conducting a race. The three best teams made it to the final round. The qualifying criteria for the contestants were the design and construction of the hovercraft, as well as the speed with which they were able to complete the course.

A high-powered battery propelled the winning hovercraft across two points in eight seconds in the first trial, while the other finalists took between thirty to forty seconds to complete the course. The fundamental concepts of aerodynamics, such as lift, were exemplified through this efficient model, crowning it the victor of the competition.

This event allowed students to learn and apply new concepts and at the same time offered the thrill of a competition. The organisers also tried to improve upon the previous year’s event and brought something new to offer students with Hover Race. “Though there was a similar event last year, we tried to improve the event by teaching the contestants something new about modern principles of aerodynamics,” said Sree Teja, the Event Head.
