Which of the following statements about Cryogenic Engines are true? 
  • a)
    Cryogenic engines use supercooled propellants, typically liquid hydrogen and liquid oxygen, to achieve high thrust and efficiency. 
  • b)
    Cryogenic engines are primarily used in interstellar space travel due to their ability to withstand extreme temperatures. 
  • c)
    Cryogenic engines operate at temperatures below -100 degrees Celsius to enhance combustion efficiency. 
  • d)
    Cryogenic engines are less efficient compared to traditional rocket engines due to the complexities involved in handling supercooled propellants.
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
Which of the following statements about Cryogenic Engines are true?a)C...
  • Context:  ISRO recently achieved a milestone by conducting the first PreBurner Ignition trial for the Semi-Cryogenic Engine (SCE)-200.
  • Cryogenic engines indeed use supercooled propellants, such as liquid hydrogen and liquid oxygen, which offer higher specific impulse and thus higher efficiency compared to traditional rocket engines. This enables them to achieve higher thrust and efficiency, making them suitable for various space missions.
  • Cryogenic engines are not primarily used in interstellar space travel, and they do not operate at temperatures below -100 degrees Celsius. Instead, they operate at extremely low temperatures, typically below -183 degrees Celsius for liquid hydrogen and below -183 degrees Celsius for liquid oxygen, to maintain them in their liquid state.
