Instead of utilizing chemical explosives to propel the projectile, the electromagnetic rail launcher creates a Lorentz force through the passage of high-current pulse through two parallel rails and the armature. This method allows for quick acceleration to high speeds, without needing explosive propellants. The railgun also offers many advantages, including faster projectile speeds, lower logistics burden of explosives, and longer distances and better accuracy. Although several technical hurdles exist, such as the need to find solutions for power supply and barrel wear, recent advancements in material sciences and pulsed power systems will progressively assist in achieving the final technical barriers to the practical implementation of railguns in future armies and space launch systems.Item Design and Development of Hybrid Solar Fruit Dryer(NHCE, 2026) S RAKSHITH -1NH23ME400 DHAYAN SAMCEER-1NH22ME016The demand for efficient and hygienic methods of fruit preservation has increased significantly due to rising food spoilage, seasonal availability of fruits, and the need for value-added products.

This project aims to develop and characterise novel composite filaments from polylactic acid (PLA) and calcium phosphate (TCP) for fused deposition modelling (FDM) of bone tissue engineering scaffolds. Medical-grade PLA and TCP will be precisely blended and melt-extruded into a homogenous filament using a single-screw extruder. The resulting composite filaments will undergo comprehensive characterisation for mechanical properties (tensile strength, flexural modulus), thermal behaviour (DSC, TGA), and morphology (SEM) to confirm uniform TCP dispersion. Printability will be assessed by fabricating complex scaffold designs. Preliminary in vitro studies will evaluate the biocompatibility and osteoinductive potential of the printed constructs.Item Design and Development of Multipurpose Agricultural Equipment(NHCE, 2026) M Manohar Reddy-1NH22ME034 Shashi Kumar V N- 1NH23ME401In India, nearly 70% of the population depends on agriculture for livelihood, yet most farming activities still rely on manual methods. These traditional practices demand heavy physical effort and expose farmers to health risks, especially during spraying and grass cutting. This project focuses on developing a Bluetooth-enabled, multipurpose automated farming device that integrates fertilizer/seed dispensing, spraying and grass cutting operations into single system. The device can be remotely controlled and monitored using a mobile application, making operations easier and safer. Overall, the system improves efficiency, reduces labor dependency, saves time, and supports smarter, technology-driven farming practices.Item Design and Development of Maglev Wind Turbines(NHCE, 2026) S. Vaishnavi -1NH22ME047 G. Brinda-1NH22ME021Wind energy is one of the most promising and clean renewable energy sources available today. However, conventional wind turbines face performance challenges, especially in low-wind regions, due to mechanical friction in bearings and the high torque required to initiate rotation. These issues lead to energy losses, frequent maintenance, and limited efficiency, especially under sub-optimal wind conditions. This project proposes a novel approach by integrating magnetic levitation (Maglev) technology into a wind turbine system. By suspending the rotating components using magnetic repulsion forces—specifically with the help of neodymium magnets—the system achieves frictionless rotation, resulting in lower startup wind speeds and significantly reduced wear and tear.Item Development of Hybrid Composite Material Using Bio Waste Particles For Sustainable Development(NHCE, 2026) Kousik Sree D V -1NH22ME031 Sundara Rajan A -1NH23ME402This investigation fabricates sustainable hybrid bio-composites from lantana camara (invasive weed), hemp fibers, VBR 8912 epoxy, and 5 wt% groundnut shell powder via compression molding (185-200°C, 2500 psi) with 5% NaOH fiber activation. Locally sourced lantana (10 mm shreds, 80°C dried), hemp, and micronized shells (10 μm) form 60-90 wt% reinforcements. NaOH roughens surfaces, boosts crystallinity (XRD ~22° 2θ), and enhances adhesion (SEM/EDAX).

Many residential and public spaces still rely on traditional staircase designs, leaving wheelchair users dependent on others for movement between different floor levels. Conventional wheelchairs are designed for flat surfaces and cannot safely operate on stairs, which increases both physical risk and emotional stress. Although commercial stair climbing devices exist, they are often expensive, complex, and difficult to maintain, making them unsuitable for widespread use, particularly in cost-sensitive environments.Item Design and Development of a Frictionless Eddy Current Braking System(NHCE, 2026) Kaushal Arul -1NH22ME030 J Sujay-1NH22ME026Most conventional braking systems operate on the principle of friction, where kinetic energy is converted into heat to reduce speed. Although effective, friction-based braking systems suffer from drawbacks such as excessive heat generation, wear and tear, noise, and frequent maintenance requirements. To overcome these limitations, this project focuses on the design and development of a frictionless eddy current braking system. In this system, braking is achieved without any physical contact by using electromagnetic induction. When a conductive aluminum disc rotates in the presence of a magnetic field produced by permanent magnets, eddy currents are induced within the disc. These currents generate an opposing magnetic force that slows down the rotation smoothly. The system was designed, fabricated, and experimentally tested using a 12V DC motor and an adjustable air-gap mechanism.
