Ramjet Meaning: Definition, Examples, and Translations
✈️
ramjet
[ˈræmˌdʒɛt ]
Definition
aeronautical engineering
A ramjet is a type ofjet engine that does not have any moving parts. It operates on the principle of air intake at high speed, compressing the air without using a compressor. The air is mixed with fuel and ignited to produce thrust. Ramjets are most efficient at supersonic speeds and are often used in military missiles and some experimental aircraft. Due to their simple design, ramjets can be lightweight and cost-effective.
Synonyms
airbreathing engine, jet engine.
Examples of usage
- The missile was powered by a ramjet for increased speed.
- Researchers are exploring ramjet technology for future aircraft.
- Ramjets are highly efficient for high-speed travel.

Origin of 'ramjet'
Main points about word origin
- The term 'ramjet' combines 'ram', meaning to push forward, and 'jet', which relates to the high-speed flow of gas.
- This technology was first conceptualized in the early 20th century but gained practical development during World War II.
The term 'ramjet' is derived from the combination of 'ram' and 'jet.' The 'ram' refers to the act of ramming or forcing air into the engine at high speed, while 'jet' pertains to the propulsion generated by the engine. The concept of ramjet engines dates back to the early 20th century, with early prototypes and theoretical works proposed by engineers such as René Lorin. However, it wasn't until the 1940s that practical applications were developed, notably in military aviation. The design of the ramjet allows it to operate effectively at supersonic speeds, making it a vital technology in missile development during the Cold War era. The simplicity and efficiency of ramjets have led to their continued exploration in various aerospace applications, particularly in experimental and high-speed vehicles.
