ISRO's Advanced Thermal Protection Systems for Gaganyaan Mission

2025-03-10

As India prepares for its manned space mission, Gaganyaan, the development of robust thermal protection systems (TPS) for the crew module is paramount. During atmospheric re-entry, the spacecraft experiences extreme aerodynamic heating, where temperatures can reach thousands of degrees Celsius. This involves intense convective and radiative heat transfer. ISRO's TPS technologies, including ablative materials and advanced ceramic composites, are designed to dissipate this immense heat, protecting the astronauts and the spacecraft's integrity. This showcases the critical role of heat transfer in extreme engineering environments.

UPSC Angle: This connects heat transfer to space technology, material science, and national security/strategic capabilities. UPSC might ask about the challenges of atmospheric re-entry, the principles behind ablative materials, or the importance of thermal management in space missions.

India's Push for Energy-Efficient Building Codes and Green Construction Standards

2024-08-15

The Bureau of Energy Efficiency (BEE) in India has been actively promoting and updating the Energy Conservation Building Code (ECBC) to mandate higher standards for thermal performance in new constructions. This directly relates to heat transfer principles, as effective building design and material selection (insulation, window glazing, reflective coatings) aim to minimize unwanted heat gain (in summers) and heat loss (in winters) through conduction, convection, and radiation. The goal is to reduce energy consumption for heating and cooling, thereby lowering carbon emissions and achieving climate targets.

UPSC Angle: This highlights the application of heat transfer in sustainable development, urban planning, and climate change mitigation. Questions could focus on the role of insulation, passive cooling techniques, or the impact of building materials on urban heat islands.
