In the ever-evolving landscape of renewable energy, where innovation meets ambition, a US-based energy start-up named Radia is poised to redefine the future of both aviation and the wind industry.

At the heart of their groundbreaking vision lies the WindRunner, an extraordinary aircraft designed to set new records and revolutionize how we approach clean energy transportation.

WindRunner is not just an aircraft; it is a colossal flying machine that, when fully certified, will hold the title of the largest and heaviest aircraft ever built by humankind.

With dimensions that dwarf even the most iconic airplanes in history, WindRunner is a feat of engineering designed to transport the world’s largest onshore wind turbines to remote, hard-to-reach locations—places where conventional transportation methods fall short.

This mammoth aircraft, which spans 356 feet in length, is 127 feet longer than a Boeing 747-400 and boasts a wingspan of 261 feet. Its towering height of 79 feet is a testament to its unparalleled design, tailored specifically to meet the demands of the modern wind industry.

WindRunner’s cargo bay volume is equally impressive, measuring 272,000 cubic feet—enough to accommodate the equivalent of three Olympic swimming pools. To put this into perspective, that’s 12 times the volume of a Boeing 747-400.

But WindRunner’s capabilities extend far beyond its sheer size. It is engineered to transport massive cargoes, including wind turbine blades up to 300 feet in length, directly to wind farms. With a maximum payload capacity of 160,000 pounds, this aircraft can carry cargoes up to 344 feet long, 24 feet high, and 24 feet wide—dimensions that push the boundaries of what was previously thought possible in airborne transportation.

To date, Radia has secured nearly $100 million in funding from a consortium of external investors. This substantial financial backing underscores the confidence in WindRunner’s potential to transform the renewable energy landscape.

India Launches Its Medium-Lift Class Helicopter Program, chooses New Engine

India’s longstanding need for a Medium Helicopter may soon become a reality as the country has fully ramped up its engine development efforts. This new helicopter is set to replace the Russian-built models currently in service and will play a crucial role across various scenarios for the Indian Armed Forces.

Hindustan Aeronautics Limited (HAL) and SAFHAL Helicopter Engines Pvt. Ltd. (SAFHAL) have launched a groundbreaking partnership to develop a state-of-the-art high-power engine named Aravalli.

This new engine will power the upcoming 13-ton Medium Lift Helicopter (IMRH) and the Deck-Based Multi-Role Helicopter (DBMRH), both of which are being designed and developed by HAL.

Named after the majestic Aravalli mountain range in India, the Aravalli engine symbolizes the country’s drive for self-reliance, or Aatmanirbharta, in critical engine technologies. This cutting-edge engine will be instrumental for the IMRH, a versatile 13-ton multi-role helicopter designed to meet the needs of the Indian armed forces, and the DBMRH, a 12.5-ton naval variant tailored for the Indian Navy.

The IMRH is poised to become a cornerstone of the Indian armed forces over the next decade. With its first flight expected in 3 to 4 years, the IMRH is anticipated to begin induction by 2030, with plans to integrate between 300 to 400 units, and potentially more in the future.

The IMRH is envisioned as a highly versatile multi-role helicopter that will enhance the operational capabilities of the Indian military. The DBMRH, designed for naval operations, will also face the challenges of high-altitude environments in regions such as Ladakh, Sikkim, and Arunachal Pradesh—areas of strategic importance due to their proximity to the China border.

In addition to its military applications, the Aravalli engine is projected to enter the civil market, serving roles in offshore operations, utility services, and VVIP transport. The long-term vision includes Maintenance, Repair, and Overhaul (MRO) activities to further extend the engine’s utility and support the aviation industry.

This collaboration between HAL and SAFHAL builds on their successful history of working together on the Shakti engine, which powers several HAL helicopters, including the Advanced Light Helicopter Dhruv, the Light Combat Helicopter Prachand, and the Light Utility Helicopter. The proven success of this partnership lays a strong foundation for the development of the Aravalli engine, setting the stage for a new era in India’s helicopter capabilities.
