jet propulsion

/'dʤetprə'pʌlʃn/

Thân thiện

A jet engine uses jet propulsion to power an airplane.

Definition

1. Noun:
   • Propulsion by means of the discharge of a jet of fluid toward the rear: A method of creating forward thrust by expelling a high-speed stream of fluid, typically gas, in the opposite direction. This principle is based on Newton's third law of motion (for every action, there is an equal and opposite reaction).

Usage

• General Use: The term is used to describe the technology or physical principle that powers certain vehicles, particularly aircraft and spacecraft.
• Technical/Scientific Use: It is a standard term in physics and engineering disciplines like aerospace and mechanical engineering.

Examples

• Noun:
  • The development of jet propulsion revolutionized air travel.
  • The squid uses a form of jet propulsion to move quickly through the water.
  • Rockets rely on jet propulsion to operate in the vacuum of space.

Advanced Usage

• "jet-propulsion engine": An engine that operates on the principle of jet propulsion. (Note: This is a compound term listed here as it is a common technical variant directly related to the core concept.)
  • The aircraft was equipped with a new, more efficient jet-propulsion engine.

Variants and Related Words

• Jet-propelled (adj): Describes a vehicle or object powered by jet propulsion.
  • The jet-propelled aircraft broke the sound barrier.
• Jet engine (n): A specific type of engine that produces jet propulsion for aircraft.
  • The jet engine's roar filled the air.

Synonyms

• Reaction propulsion: A more general technical term for propulsion generated by expelling mass.
• Thrust generation: A broader term describing the creation of forward force.

Related Phrases

• Principle of jet propulsion: Refers to the fundamental scientific law (Newton's third law) underlying the technology.
  • The course explained the principle of jet propulsion.
