    Russia Offers Upgraded BMP-3 Russia is offering its upgraded BMP-3 Infantry Fighting Vehicle (IFV), manufactured by High Precision Systems, a subsidiary of Rostec, to export customers in the Asia-Pacific region including India. A spokesperson for Russiaʼs state-owned defence export agency Rosoboronexport, which is also a subsidiary of Rostec, has said Russia is offering the upgraded vehicle to India for supporting its efforts to modernise its armoured vehicle fleets. According to the spokesperson, the baseline BMP-3 IFV has undergone several enhancements, including the integration of a firmware suite enabling the vehicleʼs autonomous operation. The spokesperson said the BMP-3 has been modified after “taking into account the experience of combat usage” gained in Ukraine. The upgraded vehicle was first displayed at the Vietnam International Defence Expo (VIDEX) 2024, held in Hanoi in December 2024. The BMP-3 features a new chassis, engine, weapons system, and hydro-m...

  Turbine blade from Turbo-Union RB199  jet engine. This is a blade with an outer shroud which prevents gas leaking round the blade tip in which case it wouldn't contribute to the force on the aerofoil. The platform at the base of the aerofoil forms a continuous annulus ring which, together with cooling-air cavity purge flow prevents hot gas leakage onto the turbine discs. The short extension, or shank, between the platform and fir-tree fixing in the disc allows space for cooling-air entry to blade, may control blade vibration modes and heat transfer to disc rim. The turbine blades have a golden colour in this engine cutaway. A turbine blade is a radial aerofoil mounted in the rim of a turbine disc and which produces a tangential force which rotates a turbine rotor. Each turbine disc has many blades.  As such they are used in gas turbine engines and steam turbines. The blades are responsible for extracting energy from the high tempe...

Examples of gas turbine: (1) turbojet, (2) turboprop, (3) turboshaft (shown as electric generator), (4) high-bypass turbofan, (5) low-bypass afterburning turbofan Gas Turbine A gas turbine or gas turbine engine is a type of continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: •      a rotating gas compressor •      a combustor •      a compressor-driving turbine. Additional components have to be added to the gas generator to suit its application. Common to all is an air inlet but with different configurations to suit the requirements of marine use, land use or flight at speeds varying from stationary to supersonic. A propelling nozzle is added to produce thrust for flight. An extra turbine is added to drive a propeller (turboprop) or ducted fan (turbofan) to reduce fuel con...
