AN INTRO TO TEAM RAKSHAK
AN INTRO TO TEAM RAKSHAK
Team rakshak is the official team of IIT Bombay consisting of 40+ students from various disciplines who work collaboratively to develop a fleet of robust Unmanned Aerial Vehicles (UAVs) to support Search and Rescue Operations (SRO) in the event of a disaster. The team was formed in the year 2015 by some of the IITB enthusiasts to build drones/planes that can be used for rescue missions. These aircraft can provide relief measures in the disaster-stricken area (e.g., Landslide, Flood, Earthquake) and can be used for surveys & mapping of cities and conservation of wildlife with slight modifications.

GARUD UAV 2022-2023
GARUD UAV 2022-2023
Garud was a fixed wing UAV Team Rakshak developed for AUVSI-SUAS competition. As a recruit in team rakshak, I took part in the making of the prototype for the UAV. Suggested methods and worked on wing mounting and attachment of landing gear. Post competiton, I also worked in scrapping up useful components from Garud.

Drone casing DESIGN
Drone casing DESIGN
As a junior design engineer, I have taken part in the process of designing and manufacturing a canopy for Skyhawk Quadrotor drone. we were tasked with the development of a casing for our drone to reduce drag and increase lift. This page is the summary of my work regarding that.
My work has been selected as final as it gave optimum and satisfactory results. Here is a summary of my cad model and simulation results. I have used Ansys fluent for CFD.

Drone Casing MANUFACTURING
The main challenge was manufacturing and we had two amazing seniors, Sanjay Kareer (design head) and Gohil Jaydeep ( Manufacturing head) of AeroD subsystem. We implemented hot wire cutting techniques to shape out the thermocol to make the mould for canopy. Unfortunately we couldn't continue the manufacturing beyond that

Parachute manufacturing
Parachute manufacturing
The main objective of skyhawk drone was to drop 5 payloads of 500g each without much damage and with considerable accuracy. Before parachute, secured free drop was suggested, which didn't work well and violated the condition for gentle impact as proposed by competition guidelines.

AMPHIBIOUS PLANE R&D
AMPHIBIOUS PLANE R&D
As part of team Rakshak's R&D project, I guided the recruits for designing a water landing gear for the RC plane they build using depron sheets.
We simplified the geometry of usual amphibious landing gears and scaled it to the bouyancy needs of the RC plane. CFD simulations were also performed. After simplification, we made a cut out plan to make it out of sheets of depron.
