What does EHOT mean in UNCLASSIFIED
EHOT stands for External Hydrogen Oxygen Tank. It is a critical component of the Space Shuttle's propulsion system, responsible for storing and supplying liquid hydrogen and liquid oxygen propellants for the shuttle's main engines during launch and ascent.
EHOT meaning in Unclassified in Miscellaneous
EHOT mostly used in an acronym Unclassified in Category Miscellaneous that means External Hydrogen Oxygen Tank
Shorthand: EHOT,
Full Form: External Hydrogen Oxygen Tank
For more information of "External Hydrogen Oxygen Tank", see the section below.
Key Features of EHOT
- Capacity: The EHOT is a cylindrical tank that can hold up to 24,500 gallons of liquid hydrogen and 11,500 gallons of liquid oxygen.
- Structure: Constructed from lightweight aluminum alloy, the EHOT is designed to withstand the extreme forces and temperatures encountered during launch and ascent.
- Insulation: The EHOT is covered with a layer of insulation to prevent heat transfer from the environment to the propellants.
- Feed Lines: The EHOT is connected to the shuttle's main engines through a series of feed lines that allow the propellants to flow into the engines.
Function of EHOT
During launch and ascent, the EHOT supplies propellants to the shuttle's main engines. The liquid hydrogen is combined with liquid oxygen in a combustion chamber, creating a high-energy exhaust that propels the shuttle upward.
Essential Questions and Answers on External Hydrogen Oxygen Tank in "MISCELLANEOUS»UNFILED"
What is an External Hydrogen Oxygen Tank (EHOT)?
An External Hydrogen Oxygen Tank (EHOT) is a type of fuel tank used in spacecraft propulsion systems. It stores liquid hydrogen (LH2) and liquid oxygen (LOX) as propellants. EHOTs are commonly used in upper stages of rockets and spacecraft for maneuvering and orbit adjustments.
What is the purpose of an EHOT?
The primary purpose of an EHOT is to provide propellants for rocket engines in space. The stored LH2 and LOX are combined and ignited to generate thrust, enabling the spacecraft to perform orbital maneuvers, attitude control, and other propulsion-related functions.
What are the advantages of using EHOTs?
EHOTs offer several advantages:
- High propellant density: LH2 and LOX have high energy density, providing greater specific impulse (efficiency) for rocket engines.
- Efficient operation in space: EHOTs allow for efficient operation in the vacuum of space, where traditional combustion engines are impractical.
- Reliability: EHOTs are generally reliable and have been successfully used in numerous space missions.
What are the challenges associated with using EHOTs?
Using EHOTs also presents some challenges:
- Cryogenic handling: LH2 and LOX are cryogenic fluids that require specialized handling and storage techniques to prevent boil-off and maintain their low temperatures.
- Insulation: EHOTs require extensive insulation to minimize heat transfer and maintain the cryogenic state of the propellants.
- Safety considerations: Hydrogen and oxygen are highly flammable and must be handled with extreme caution to prevent accidents.
Final Words: The EHOT is an essential part of the Space Shuttle's propulsion system, providing the fuel and oxidizer necessary for launch and ascent. Its design, construction, and function have played a crucial role in the success of numerous shuttle missions.
