India’s Hindustan Aeronautics, Ltd. is Now 3D Printing Aircraft Engine Components

“Given the high expectation built around the Company, my priorities would be to concentrate on operational excellence, and build the company as technology powerhouse,” said T. Suvarna Raju upon taking position as the new Chairman at Hindustan Aeronautics, Ltd. (HAL) at the beginning of this month.

Raju’s vision for HAL is to move India’s only manufacturer of military aircraft ever morHome_HAL_logoe firmly into the realm of world-class aerospace firms, and is embracing his government’s push toward “Made-in-India” labels affixed to high-quality products. He recognizes that “the Best of Technologies can never be bought, it can only be developed,” and to that end is enhancing HAL’s focus on research and development. HAL has developed a strategic business unit (SBU) to focus on the unmanned aerial vehicle (UAV) market, which in India alone has the potential to be worth $2 billion.

As it turns out, 3D printing will be along for the ride.3D-printed-mini-jet-engine-from-GE1

HAL is looking to additive manufacturing to create components for a 25-kilonewton (kN) aircraft engine, with the overall project valued at Rs 458 crore (over $73 million USD). Raju recently told India’s Deccan Herald that the project was going smoothly until recently, when a supplier reneged on the deal. The 6-and-a-half-year-long project requires the critical components that this particular vendor was due to contribute, and so their backtracking could easily have halted progress quite rapidly. HAL, however, is not one to give up so quickly, and instead of looking to that outside supplier or trying to find another, the company purchased its own 3D printing equipment.

The company’s first engine design is ready for display; an operational version of the engine will be shown next week at Aero India, “Asia’s Premier Air Show.” HAL will have the unit on display at their exhibition space.

HAL’s successful designs also include an 8-kg UAV, which will also be shown at Aero India. The next step there is creating a 10-kg rotary unit, for which R&D is already underway, including work with IIT Kanpur. Researchers there have successfully created a quadcopter, so further UAV development seems right on track.

Raju “would like HAL to grow as a knowledge based organization,” which dovetails with his drive toward company R&D activity. Under Raju’s oversight, HAL has earmarked 10% of its post-tax profit for R&D ventures. Further adding to their research and development efforts is HAL’s drive to set up chairs in academia, including at campuses such as IIT Channai (working on gear boxes), IIT Mumbai (communications), IIT Kharagpur (radar and electronic warfare), and IIT Kanpur (UAVs).

Under Raju’s direction, HAL seems to be on the right track toward tech-based progress. India’s sole military aircraft producer seems to be increasingly well positioned to lead the country’s charge forward, and 3D printing capabilities at the company will serve only to enhance that process. Rapid prototyping will lead to improvements in iteration — a certain benefit in creating such ambitious projects as the 25-kN one on the table now.
