In a major leap toward self-reliance in defense technology, India is set to develop its very own fifth-generation fighter jet—the Advanced Medium Combat Aircraft (AMCA) . In a historic move, Defence Minister Rajnath Singh has approved an innovative execution model for the indigenous stealth fighter programme. This model brings together Hindustan Aeronautics Limited (HAL) and private industry players in a competitive framework, marking a significant shift in how India approaches military aviation manufacturing. This bold initiative comes at a critical time, as China has already fielded two fifth-generation fighters , and reports indicate it will supply 40 J-35 stealth jets to Pakistan . Against this backdrop, fast-tracking the AMCA has become an urgent national security imperative. AMCA: India’s Indigenous Stealth Fighter Dream The AMCA project , spearheaded by the Aeronautical Development Agency (ADA) under the Defence Research and Development Organisation (DRDO) , received its l...
Researchers' Work Towards Better, Fatigue-Resistant Alloys Introduction Fatigue failure is one of the most critical challenges in materials engineering, impacting industries such as aerospace, automotive, and structural engineering. To combat this, researchers are working on developing fatigue-resistant alloys that can withstand repeated stress cycles without compromising structural integrity. This article explores the latest advancements in fatigue-resistant materials , the science behind fatigue failure, and how emerging technologies like machine learning, nanotechnology, and additive manufacturing are revolutionizing the field. Understanding Fatigue Failure in Alloys Fatigue failure occurs when a material experiences cyclic loading, leading to the gradual formation and propagation of cracks until the material ultimately breaks. The key factors affecting fatigue resistance include: Stress amplitude and mean stress Microstructural characteristics Environmental conditions (e...
