TheDefence Research and Development Organization (DRDO) recently achieved a significant milestone by successfully conducting a flight trial of the Autonomous Flying Wing Technology Demonstrator, an indigenous high-speed flying-wingUnmanned Aerial Vehicle (UAV).This successful demonstration places India in an elite group of countries that have mastered the controls for flying wing technology.Elite Club EntryThe Defence Ministry announced on Friday that the DRDOconducted a successful flight trial of the autonomous flying wing technology demonstrator in Karnataka’s Chitradurga. With this achievement, India joins an elite club of countries that have mastered the controls for flying wing technology, showcasing a remarkable advancement in the nation’s technological readiness levels.Development by DRDOTheUAV, designed and developed by DRDO’s Aeronautical Development Establishment, marks a significant step leap inIndia’s aerospace capabilities.Defence Minister Rajnath Singhcommended the DRDO, armed forces and the industry for the successful flight trial, emphasizing the strengthening of the armed forces through the indigenous development of critical technologies.Flight Trials and Technological AdvancementsThemaiden flight of the aircraft took place in July 2022, followed bysix subsequent flight trialsin various developmental configurations, utilizing two in-house manufactured prototypes. These trials led to advancements in aerodynamics, control systems, real-time simulation, hardware-in-loop simulation and ground control stations. The final flight in the tailless configuration demonstrated India’s control mastery of flying wing technology.Aerospace Technology ShowcaseThe UAV prototype features a complex arrowhead wing platform constructed from lightweight carbon prepreg composite material developed indigenously. The composite structure, equipped with fiber interrogators for health monitoring, serves as a testament to ‘Aatmanirbharta’(self-reliance) in aerospace technology, showcasing India’s ability to innovate and manufacture advanced materials domestically.Autonomous Landing CapacityOne of the standout features of the UAV is its autonomous landing capability, eliminating the need for ground radars, infrastructure or a pilot. This unique capability allows for take-off and landing from any runway with surveyed coordinates. The autonomous landing was made possible through onboard sensor data fusion, coupled with indigenous satellite-based augmentation usingGPS-aided and GEO Augmented Navigation (GAGAN) receivers, enhancing GPS navigation accuracy and integrity.
