Semi-Cryogenic Propellant Tank

 

Why in News

Recently, Hindustan Aeronautics Ltd (HAL) delivered the heaviest semi-cryogenic propellant tank (SC120- LOX) to the Indian Space Research Organization (ISRO).

  • In 2020, HAL delivered the biggest ever cryogenic Liquid Hydrogen tank (C32-LH2) to ISRO.

Key Points

  • About:
    • The semi cryo-liquid oxygen (LOX) tank - the first developmental welded hardware - is a part of the SC120 stage intended for payload enhancement by replacing the L110 stage in the existing Mk-III launch vehicle.
      • GSLV Mk III is a three-stage heavy-lift launch vehicle developed by ISRO. The vehicle has two solid strap-ons, a core liquid booster and a cryogenic upper stage.
  • Cryogenic Engine:
    • A cryogenic engine/cryogenic stage is the last stage of space launch vehicles which makes use of Cryogenics.
      • Cryogenics is the study of the production and behaviour of materials at extremely low temperatures (below -150 degree Centigrade) to lift and place heavier objects in space.
    • A cryogenic engine provides more force with each kilogram of cryogenic propellant it uses compared to other propellants, such as solid and liquid propellant rocket engines and is more efficient.
    • It uses Liquid Oxygen (LOX) and Liquid Hydrogen (LH2) as propellants which liquefy at -183 deg C and -253 deg C respectively.
  • Semi Cryogenic Engine:
    • Unlike a Cryogenic engine, a Semi Cryogenic engine uses Refined kerosene instead of liquid hydrogen.
    • The liquid oxygen is used as a Oxidiser.
      • That’s the advantage of using a Semi Cryogenic engine as it requires Refined Kerosene which is lighter than liquid fuel and can be stored in a normal temperature.
    • Kerosene combined with liquid oxygen provide a higher thrust to the rocket.
    • Refined Kerosene occupies less space, making it possible to carry more propellant in a Semi Cryogenic engines fuel compartment.
    • A semi cryogenic engine is more powerful, environment friendly and cost effective as compared to a cryogenic engine.

India Considers Selling BrahMos Missiles to Russia, Paving the Way for a Strategic Shift !

Introduction: Recent reports indicate that India is contemplating the sale of BrahMos missiles to Russia, a move that could signify a potential role reversal between the two longtime strategic allies. The BrahMos missile, a joint creation of India and Russia, has evolved into a formidable weapon system. Atul Dinkar Rane, the CEO and managing director of BrahMos Aerospace, discussed the organization's interest in exploring the Russian market for the air-launched version of the supersonic cruise missile. This development comes amidst Russia's continued reliance on the Soviet-era P-800 Onyx missile, which pales in comparison to the advanced capabilities of the BrahMos. However, the recent geopolitical tensions and conflicts in Europe have impacted the potential for such a sale. Let's delve deeper into the implications and prospects of India's decision and its potential impact on Russia's military capabilities.   India's Deliberations on BrahMos Missile Sales to R...
