Traditionally, increasing the range of artillery required either larger guns (which reduces mobility) or expensive rocket-assisted projectiles (which often sacrifice the explosive payload\/lethality). By integrating a ramjet engine\u2014which uses the shell&#8217;s own forward velocity to compress air for combustion\u2014IIT Madras has found a way to <strong>increase range by nearly 50%<\/strong> while maintaining the shell&#8217;s original destructive power.<\/p>\n\n\n\n<p>For students and aspirants in Aerospace Engineering and Defense Research, this project signifies a shift toward <strong>Indigenous Modernization<\/strong>. It proves that India can upgrade existing &#8220;legacy&#8221; hardware (like the 155mm Bofors or Dhanush guns) into high-tech precision systems at a fraction of the cost of new missile batteries. This success, fueled by the &#8220;Professor of Practice&#8221; initiative, bridges the gap between academic theory and frontline military application.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-technical-specifications-amp-requirements\">Technical Specifications &amp; Requirements<\/h2>\n\n\n\n<p>Based on the research and press release, here are the core requirements and features of the new technology:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Platform Compatibility:<\/strong> Designed specifically for <strong>155 mm artillery guns<\/strong>, the standard caliber for the Indian Army.<\/li>\n\n\n\n<li><strong>Propulsion Mechanism:<\/strong> Replaces the standard &#8220;base-bleed&#8221; unit with a <strong>solid-fuel ramjet engine<\/strong>.<\/li>\n\n\n\n<li><strong>Performance Metric:<\/strong> Targets a range extension from the standard 30-40 km to over <strong>60+ km<\/strong>.<\/li>\n\n\n\n<li><strong>Core Principle:<\/strong> Employs atmospheric oxygen for combustion, meaning the shell carries more fuel\/explosives rather than an oxidizer.<\/li>\n\n\n\n<li><strong>Key Components for R&amp;D:<\/strong> * High-speed air intake system.\n<ul class=\"wp-block-list\">\n<li>Solid propellant grain.<\/li>\n\n\n\n<li>Nozzle assembly designed for gun-launch G-forces.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-historical-trends-amp-research-analysis\">Historical Trends &amp; Research Analysis<\/h2>\n\n\n\n<p>Historically, the Indian Army has relied on &#8220;Base Bleed&#8221; technology to reduce base drag and increase range by roughly 10-20%.
