Advancements in the aviation sector have consistently aimed to maximize efficiency through a multi-disciplinary approach, focusing on optimizing both structural and aerodynamic performance. Although modern aerospace structures are engineering marvels, they often lack or limit the flexibility observed in nature—such as the flexible, flapping wings of birds. This contrast underscores a significant opportunity to enhance […]

This seminar presents a systematic methodology for the design of flight control laws for Medium Altitude Long Endurance (MALE) UAV operating at high altitudes, including the development of control law for fully autonomous take-off and landing operations. The process begins by developing a detailed model of the aircraft, incorporating parameters such as mass, inertia, aerodynamic […]

Shape Memory phenomenon in some intermetallics like NiTi is well known. However, during arbitrary thermomechanical loading, these materials exhibit several other interesting, yet less-understood phenomena. In this talk, Thermal Arrest Memory and associated effects during interrupted phase transformations in shape memory alloys are discussed and some fascinating underpinnings in the associated martensitic transformations are highlighted. […]

Some decades ago J. T. Stuart formulated a theory for nonlinear saturation of hydrodynamically unstable modes. He proposed that an unstable mode, upon gaining sufficient energy, distorts the mean flow. This mean flow distortion reduces the shear, thus reducing the inviscid energy production mechanism which eventually results in a saturation of instability. In a hypersonic […]

Abstract: The presentation opens with a comparison of high-temperature materials with everyday metals. This will be followed by a discussion of challenges and an understanding of the machinability of high-temperature materials. Next, various strategies for machining high-temperature materials, along with practical real-life case studies, will be presented. We will be introducing the concept of Feed […]

With the climate change becoming as one of the main challenges for human existence, every sector has to contribute in reducing its climate footprint. Being an international and hard to abate sectors, aviation is struggling to find a viable replacement for kerosene. This talk focuses on a novel multi-fuel combustion strategy that is aimed at […]
