Bharat Innovates 2026 showcases Green Aero Propulsion Pvt. Ltd., a pioneering deep-tech startup transforming the future of aerospace through sustainable propulsion technologies. Incubated at IIT Delhi, the company is developing next-generation hydrogen-powered and multi-fuel aero engines aimed at decarbonizing aviation and reducing dependence on fossil fuels. With a strong focus on indigenous innovation, Green Aero is building high efficiency propulsion systems for both civilian and defence applications, including drones, aircraft, and advanced mobility platforms. Green Aero Propulsion Pvt. Ltd is also part of an elite group of deep-tech startups selected for the prestigious Bharat Innovates 2026 program by the Ministry of Education, Government of India, to be showcased from 14–16 June 2026 in Nice, France. With breakthrough milestones such as the successful test-firing of India’s hydrogen powered aero engine core, the startup is positioning itself at the forefront of clean aviation technology. By combining fuel flexibility, advanced turbine design, and waste-heat recovery systems, Green Aero is enabling more efficient and environmentally friendly flight solutions. As part of Bharat Innovates 2026, the startup represents India’s growing leadership in deep-tech and sustainable aerospace innovation driving a greener and self-reliant future.

#WATCH | ANI National Security Summit 2.0: DRDO Chairman Dr Samir V Kamat says, "For short-range ballistic missiles, the Pralay is now in the final stages of testing. With respect to hypersonic, we are working on two programs, the hypersonic glide missile and the hypersonic cruise missiles. The glide missile will come out first. We should be doing the first trials fairly soon. And that is at a more advanced stage than the cruise missile. The cruise missile program has not yet been sanctioned, although we are working on the various technologies which will get into the cruise missile..." "For short-range ballistic missiles, the Pralay is now in the final stages of testing and should be ready. Then we have some of our strategic missiles, which can be converted to tactical usage for the medium range and the long range. With respect to hypersonic, we are working on two programs, the hypersonic glide missile and the hypersonic cruise missiles. The hypersonic cruise missiles is one which has a scramjet engine and it is powered during its flight. The hypersonic glide missile is a missile which uses a booster to give it initial velocity, and then it just glides without any powering. The glide missile will come out first. We should be doing the first trials fairly soon. And that is at a more advanced stage than the cruise missile. The cruise missile program has not yet been sanctioned, although we are working on the various technologies which will get into the cruise missile. Recently, we have done a scramjet propulsion for more than 1,000 seconds. So that's been a major achievement, and once the program is sanctioned, we'll convert the scramjet propulsion into a working missile system. And I think that should take about five years after the sanction."

This is the most powerful commercial jet engine currently flying on an operational airliner. The GE90-115B was built by GE Aerospace specifically for the Boeing 777-300ER. It weighs around 8.3 tonnes, has a 3.25 metre wide fan and produces up to 512 kN (115,000 lbf) of thrust from a single engine. To understand the sheer scale of that output, it produces roughly 2.7 times the thrust of the F135 jet engine powering the F-35, the most powerful fighter engine currently in service. The enormous fan at the front uses just 22 carbon fibre composite blades with titanium leading edges. At maximum thrust, it pulls in roughly 1.4 tonnes of air every second, with nearly 90% bypassing the core rather than passing through the combustor. At around 150 knots during takeoff, its 512 kn of thrust corresponds to roughly 39.5 MW of propulsive power, or in automotive terms around 53,000 hp from one engine. And it burns roughly 4-5 kg of jet fuel every second at maximum power conditions. Two of these engines are enough to power a fully loaded 777-300ER weighing more than 350 tonnes. Even if one engine fails after the critical point during takeoff, the aircraft is certified to continue the takeoff and climb on the remaining one GE90 engine. Each engine costs around $35-40 million. More than 2,500, GE90s engines have been built, and the GE90 family has accumulated nearly 130 million flight hours. And this is precisely why companies like GE Aerospace remain so difficult to displace in jet engines. There is never one breakthrough. GE spent roughly $2+ billion developing the GE90, chasing small gains across hundreds of systems, efficiency, materials, reliability and component life.
