  • INDRA RV25: 240N: Hyderabad-based Raghu Vamsi Machine Tools Private Limited recently launched its fully indigenous Micro Turbojet Engine “INDRA RV25: 240N”. It is a micro turbojet engine. It is designed and developed indigenously by Hyderabad-based firm Raghu Vamsi Machine Tools with support from IIT Hyderabad. It has primarily been developed for unmanned aerial vehicles (UAVs) or drones. The engine has applications in UAVs, air taxis, jetpacks, auxiliary power units, range extenders, and power generation in the future. 

 

  • Turbojet Engine: A turbojet engine is a jet engine which produces all of its thrust by ejecting a high-energy gas stream from the engine exhaust nozzle. In contrast to a turbofan or bypass engine, 100% of the air entering the intake of a turbojet engine goes through the engine core. The component parts of a turbojet engine are the inlet, the gas turbine engine, consisting of a compressor, a combustion chamber and a turbine, and the exhaust nozzle. 

Working: Air is drawn into the engine through the inlet and compressed and heated by the compressor. Fuel is then added to the combustion chamber and ignited. The burning fuel adds energy to the exhaust stream by heating and expanding the air. Sufficient energy to drive the compressor is extracted from the exhaust stream by the turbine. The remainder of the exhaust energy is used to produce thrust, a process which is enhanced by the geometry of the exhaust nozzle.  

As the exhaust gas passes through the nozzle, it is accelerated to high speed as it expands, thus providing propulsion. The thrust produced by the engine can be selectively increased by incorporating an afterburner or re-heat into the engine design. Turbojet aircraft work on the principle of accelerating a relatively small mass of air to a high speed. Thus, turbojets have relatively poor propulsive efficiency at lower airspeeds, limiting their usefulness to high-speed aircraft. 

 

  • Aegis Graham Bell Awards: Recently, the Centre for Development of Telematics (C-DOT), the premier Telecom R&D centre of the Government of India, strikes a hat-trick by securing top position in three awards at 14th Annual Aegis Graham Bell Awards. It was initiated in 2010 by the Aegis School of Data Science. It is a tribute to the father of telephony and great innovator, Alexander Graham Bell. The Aegis School of Business, Data Science and Cyber Security has initiated this award to promote innovations and recognise the outstanding contributions by innovators in various fields including education, Information and Communications Technology (ICT), Artificial Intelligence (AI) and data science. This award in India is supported by the Ministry of Electronics and Information Technology (MeitY), Skill India and the National Informatics Centre. Following are the projects of C-DOT which received this award:  
    • ASTR Project: ASTR (AI & Facial Recognition-powered Solution for Telecom SIM Subscriber Verification) is a game-changer in the fight against cybercrimes.  
    • Designed to analyse, identify, and eliminate fake/forged mobile connections, it’s a crucial step towards ensuring a secure telecom environment. 
    • CEIR (Central Equipment Identity Register) solution: CEIR helps revolutionise mobile security by detecting clone IMEIs, restricting the import of counterfeit mobile devices and also enabling the blocking and tracing of lost or stolen phones. 
    • Quantum Key Distribution (QKD) product: India employs quantum mechanics to create an unbreakable cryptographic protocol even with Quantum computers.
