Hybrid Rocket Propellant Grains: A ReviewBy Nishad Bhavsar, Paarth Saxena, Prasad Sawant, Maitreyee Birajdar, Pandi Siddharth
Abstract: The go-to-rocket propulsion system is either solid rocket motor or liquid rocket engine, but both have their own drawbacks like solid rocket motors cannot be throttled or stopped and started again or the construction of liquid propulsion systems is quite complex, with difficulty in storage and major safety issues. A hybrid rocket propulsion system uses either fuel or oxidizer in solid form and the other in liquid and has a …

Enhancing Space Safety: A Review of CubeSat Constellations for Tracking Orbital DebrisBy Trisha Shailesh Salvi, Sanjana Sanjay Nalawade, Vijaykumar Gorfad, Pandi Siddharth
Abstract: Space debris includes any human-made object in orbit or idle. Debris reentering the atmosphere or orbiting the Earth are examples of these things. Debris can include satellites or launch vehicles, dysfunctional spacecraft, remains from rockets and airplanes from crashes or explosions, debris from spacecraft and vehicles that were purposefully expelled during separation or operation, etc. The danger of collisions rises as the number of items in the path increases. Over …

Balloon Deployment Strategies for Projectile DeterrenceBy Sayali Fund, Samia Shameer, Drashya Rawal, Pandi Siddharth
Abstract: This paper presents a defense strategy inspired by historical precedents, aimed at neutralizing subsonic projectiles using a swarm of balloons filled with explosive and buoyant gases, such as hydrogen. The balloons are arranged in a swarm to effectively intercept multiple incoming projectiles. Numerous military and security uses are possible for them. Operating costs for lighter-than-air aircraft are lower than those of traditional fixed-wing aircraft. Lighter-than-air vehicles can be made less …

Leveraging Origami for Space Efficiency: A Comprehensive Review of Its Role in AerospaceBy Kabir Belsare, Rutvik Ekshinge, Sampada Game, Shravani Kulkarni, Pandi Siddharth
Abstract: Originating in East Asia, origami has developed beyond its original artistic medium to play a significant role in the design of adjustable systems, especially in the sector of space engineering. Due to tight weight and space constraints, these structures which are essential for aviation and spacecraft make effective use of the geometric qualities of origami. This study provides a summary of recent research, emphasizing the benefits, technical applications, and uses …

CFD Analysis of a Bladeless Propelling Unit for the DronesBy Asmi Raipalli, Prerana Dhawle, Tanaya Joshi, Shraddha Gunjal, Pandi Siddharth
Abstract: Conventionally, unmanned aerial vehicles (UAVs) and autonomous aerial vehicles (AAVs) utilize bladed propellers to produce lift, altitude, and thrust for propulsion. Yet, these blades are susceptible to abrasion when they contact external surfaces, resulting in diminished operational efficiency over time. Our ongoing investigation introduces a pioneering approach by integrating bladeless propeller technology, drawing inspiration from Dyson’s Bladeless Fan Theory. This study seeks to address the wear-related shortcomings of conventional propeller …
