HAL Tejas India's Home Grown Fighter
Show Notes Transcript

The Tejas is a single-engine multirole fighter which features a tailless, compound delta wing design that omits horizontal stabilizers in the tail.  This allows for better close-combat, high-speed, and high-alpha performance characteristics than comparable traditional wing designs.  Extensive wind tunnel testing on scale models and complex computational fluid dynamics analysis have optimized the aerodynamic configuration for minimum supersonic drag, a low wing-loading, and high rates of roll and pitch. Tejas is designed with "relaxed static stability" for enhanced maneuverability and agility. Originally intended to serve as an air superiority aircraft with a secondary ground-attack role, its flexibility permits a variety of guided air-to-surface and anti-shipping weapons to be integrated for multirole and multi-mission capabilities.
