In a significant step for India's aerospace sector, Hindustan Aeronautics Limited (HAL) successfully conducted the maiden flight of its new Advanced Light Helicopter Dhruv–New Generation (NG) in Bengaluru on Tuesday. This event marks a pivotal move in HAL's strategy to adapt the proven Dhruv platform for the competitive civil aviation and international export markets.
A Milestone for Indigenous Aviation
Civil Aviation Minister K Ram Mohan Naidu hailed the achievement as a key milestone for the country's civil aviation manufacturing ecosystem. He emphasized that the project showcases improved coordination between aircraft manufacturers and regulatory bodies, which is crucial for reducing the time required for certification of new aircraft.
The Dhruv-NG is a 5.5-tonne, twin-engine, multi-role helicopter designed and manufactured by HAL. It is an upgraded version of the existing Dhruv platform, with enhancements specifically targeted at:
- Safety and Performance: Incorporating advanced systems for safer and more reliable operations.
- Ride Quality and Passenger Comfort: Focused on making the helicopter more appealing for civilian and VIP transport roles.
- Operational Capability: Retaining the ability to operate effectively in hot and high-altitude conditions typical of the Indian subcontinent.
Power of the Indigenous Shakti Engine
At the heart of the Dhruv-NG's upgrades are its twin Shakti 1H1C engines, which are fully indigenous. The Directorate General of Civil Aviation (DGCA) has already granted a type certificate for this engine, declaring it as India's first certified civil turboshaft engine.
Developed by the Aero Engine Research and Design Centre (AERDC)–HAL in Bengaluru, the Shakti 1H1C engine delivers a maximum continuous shaft power of 568KW. HAL states that using this indigenous powerplant offers higher power ratings and the significant advantage of in-country maintenance and support. This not only boosts national self-reliance under the 'Aatmanirbhar Bharat' initiative but also promises to lower long-term operating and lifecycle costs for operators.
The Road Ahead: Testing and Certification
HAL Chairman and Managing Director, DK Sunil, outlined the next phase for the Dhruv-NG program. The company plans to conduct an extensive flight test campaign involving approximately 130 flights over the next few months. These tests will be carried out using two prototype helicopters to rigorously validate all performance and safety parameters.
This successful maiden flight is more than just a test; it is a strong statement of intent from HAL. By repositioning the Dhruv platform for civil and export markets, HAL aims to capture a share in the global utility helicopter segment, leveraging India's engineering prowess and cost-effective manufacturing capabilities.
