  How Mathematical Modelling and Optimisation Guide Spacecraft Trajectories

  By Nandika Kohli

  Abstract: Spacecraft trajectory design is fundamentally a mathematical problem involving the prediction, evaluation and optimisation of motion under complex physical constraints. This article explores how mathematical modelling and optimisation are used to determine feasible and efficient trajectories for spacecraft. Beginning with the simplified two-body model, the article introduces the differential equation governing gravitational motion and explains how initial position and velocity determine the subsequent trajectory. It then examines how trajectory design …

  Effect of Leading-Edge Roughness on the Aerodynamic Characteristics of the Wind Turbine blade

  By Santhosh Sabapathy

  Abstract: Leading-Edge Roughness (LER) strongly dictates boundary layer transition and performance degradation on an airfoil operating at transitional Reynolds numbers, an aerodynamic regime where shear-layer stability mechanisms remain highly complex. The wind tunnel experiments were conducted to investigate the aerodynamic impacts of surface roughness applied over 25% of the chord of a NACA 0018 airfoil using two discrete roughness gradations. Surface roughness induces an early boundary layer trip, causing elevated section …

  Transfer Learning Based High-Precision Multi-Class Object Detection for Real-Time UAV Autonomous Landing via YOLOv8l in Unstructured Scenarios

  By Vivek Verma, Vaibhav Singh

  Abstract: A significant challenge for autonomous drone landings in unstructured environments is that of reliably detecting and identifying objects in real-time to ensure safety and accuracy of the landing area. This paper presents a well-founded method for solving this problem using the YOLOv8l object detection framework to detect landing zones, obstacles and people in the relevant vicinity of the landing area. The dataset used for the training of the model contained …

  Metamaterial-Based Thermal Shielding Structures for Reusable Hypersonic Space Transportation Systems

  By Bibhu Prasad Ganthia, Subash Ranjan Kabat

  Abstract: The rapid development of reusable hypersonic space transportation systems has intensified the need for advanced thermal protection technologies capable of withstanding extreme aerodynamic heating conditions encountered during atmospheric re-entry and sustained hypersonic flight. Conventional thermal shielding materials often suffer from high structural weight, limited adaptability, thermal fatigue, and degradation under repeated thermal cycling. This study proposes a novel Metamaterial-Based Thermal Shielding Structure for Reusable Hypersonic Space Transportation Systems, integrating engineered …

  Industrial Prognostics via Ensemble Machine Learning: An Uncertainty Aware Framework for RUL Estimation on NASA FD004 Telemetry

  By Taufique khan Asadulla Khan, Sonali Nimbhorkar

  Abstract: Estimating the Remaining Useful Life (RUL) of industrial machinery in real-time is now vital for both operational safety and smart resource management. In the aviation industry, turbofan engines deal with constantly shifting flight conditions, making traditional, scheduled maintenance both expensive and prone to error. This paper addresses the flaws in common “point-prediction” AI models, which offer a single failure date without any margin for error, by introducing a new, uncertainty-aware …

  Effect of Blunt Truncation in an Aerospike Nozzle

  By Vijai Raaj K R, Yukesh Kanna M, Maheshwaran C, Mohamed Zameer M S

  Abstract: Aerospike nozzles are gaining attention as a more advanced alternative to conventional bell nozzles, mainly because they can perform efficiently across a wide range of altitude conditions. Unlike traditional converging–diverging nozzles, aerospike designs naturally adjust to changes in ambient pressure, allowing the exhaust flow to expand more effectively. This results in better thrust performance under varying operating conditions, making them a strong candidate for future aerospace propulsion systems. In this …

  EGT Margin of A Jet Engine – Cause, Impact, Improvement & Simulation Theory

  By Sandeep Prajapati

  Abstract: When an engine runs, it produces heat and there is a range of temperature in the engine chamber. For Jet Engines, when it starts, temperature starts increasing within a range. At various durations of the engine run, there is some temperature. Higher the thrust, higher the heat temperature. This temperature is called Exhaust Gas Temperature (EGT). There is a maximum allowed gas temperature for each type of engine and the …
