MNNIT to study lightning impact on planes
Funded by the
Defence Research and Development Organisation
(DRDO), the project, costing around Rs 60 lakh, was awarded to Ashutosh Kumar Upadhyay, associate professor in the applied mechanics department at MNNIT.
The research puts spotlight on the May 21 incident wherein the front portion of a plane travelling from Delhi to Srinagar was damaged due to a storm and lightning strike jeopardizing the lives of 227 passengers. Upadhyay said the damage to planes due to lightning is a serious problem.
"The cause of damage to planes from lightning will be investigated. Research is being conducted to identify which mixed substances can reduce the effect of lightning. Planes are at risk from both lightning and charge because they become a medium for the current between two clouds. This study focuses on composite panels used in modern aircraft. It will be analysed how lightning strikes affect the structure, temperature, electrical flow, and mechanical strength of the panel," said Upadhyay.
He said electrical, heat and mechanical effects will be combined through multi-physics modelling techniques to understand the type of damage and its impact on the aircraft.
Based on this, a new code will be prepared, and the simulation software will be updated with this code, allowing the electrical resistance capacity of the new material to be easily tested. This will reduce the effect of lightning on the aircraft. DRDO has assigned this project for three years. A JRF will be appointed for the project.

India has made huge leap in missile technology: Former DRDO chairman
Dr G Satheesh Reddy COIMBATORE: India has reduced its missile production turnaround time from 10-12 years to 2-3 years, making a huge leap in technology, said Dr G Satheesh Reddy, president of the Aeronautical Society of India and former secretary of Directorate of Defence Research & Development and chairman of DRDO . 'This enables us to stand on a par with developed countries like the US, Russia and China though these countries are one to two decades ahead of us," he told TOI on the sidelines of a programme in Coimbatore on Saturday. "India is a missile power. India is actively developing hypersonic missiles and air-to-ground-borne missiles like the BrahMos,' he said. He said India has 300-400 drone manufacturing companies with nearly 25,000 AI engineers in the southern region. They are capable of making the world use products made in India. "So far, India was working for others, getting their products. Now India has to make them get our products and also get them to work for us," he said. Earlier, addressing at the Academia-Industry Meet 2025 for Aerospace & Defence, hosted by the Kumaraguru Centre for Industrial Research & Innovation in association with the Aeronautical Society of India, he highlighted four key takeaways from Operation Sindoor. First, the Indian armed forces have gained confidence in indigenous technologies. Second, it boosted the morale of the country. Third, the industry has witnessed success, which will increase orders. Lastly, the world has seen India's capabilities, which is expected to increase export orders as well.

Planetarium to get observatory dome, telescope
Patna: In a move aimed at enhancing scientific engagement and promoting astronomy education, deputy CM Samrat Choudhary on Saturday announced that an observatory dome and an additional telescope will soon be installed at the planetarium here. Tired of too many ads? go ad free now The project, estimated at Rs 99 lakh, is set to be executed through the National Council of Science Museums (NCSM), Kolkata, an autonomous body under the Union ministry of culture. The initiative has been proposed by the Bihar Council on Science and Technology and also includes a consultation fee of Rs 14 lakh. The NCSM had earlier supplied a telescope to the planetarium. Calling the project a significant step towards nurturing scientific curiosity, Choudhary said, "This is an important initiative by the state government aimed at fostering scientific thinking and research aptitude among the youth of the state." He added that the modernisation of the planetarium would not only raise scientific awareness among the general public, particularly young people, but also deepen the interest of science students in astronomy.

Scope for bridge between India, international startups in defence and aerospace sector: Union minister Piyush Goyal
Academy Empower your mind, elevate your skills Union Commerce and Industry Minister Piyush Goyal on Saturday said there is scope to establish a connection or "bridge" between Indian and international start-ups within the defence and aerospace further expressed confidence that India is poised to become a preferred supplier for the defence and aerospace sector in the near future."...there is scope for a bridge or a connection between startups in India and internationally in the space of defence and aerospace. I will ask Startup India to see, and we will use the services of the companies and their connection, if we can connect the two," Goyal said in response to a reporters after visiting the Aerospace SEZ at KIADB Export Promotion Industrial Area in Devanahalli near here, he said the defence and aerospace zone will be the beginning of a path-breaking journey in the field."I have absolutely no doubt that in the years to come, particularly given the great relationships that India is creating with many other developed countries, India will become a preferred supplier for defence and aerospace," he the design and innovation activity happening within global capability centres in India, Goyal said, "Now we will not only design and innovate in India, we will patent in India, we will produce in India and hopefully become a globally relevant partner in the supply chain. I'm truly very very optimistic about the potential of this sector." Earlier, after attending the Industry Interaction in Bengaluru, the Union Minister told media that the deep tech industry, the startup ecosystem which is present in the city in a big way is a "jewel in our crown"."We are proud of the good work that the tech sector, particularly the global capability centres are doing," he said and assured that the Government of India will extend full support to the technology industry and the startup out that the union cabinet recently approved a scheme to provide Rs 1 lakh crore to promote research and development and innovation, Goyal said, "We have also come out with a Rs 2 lakh crore employment generation incentive scheme along with several other programmes for skill development, the PM internship programme, and several other initiatives." "The startup fund of funds of Rs 10,000 crore, and all of these put together, will give deep encouragement to support the growing startup ecosystem, tech ecosystem and manufacturing ecosystem," he added.
