They do not have moving parts (e.g. compressor blades, shaft, turbine blades) needed by turbojet engines, increasing reliability, reducing maintenance costs, and permitting them to operate at faster airspeeds.
However neither can be used at low airspeeds at all, being a significant disadvantage as a different engine (e.g. turbojet, rocket) must also be provided for takeoff and landing.
The two main types of rocket engines are Solid fuel rocket engines and Liquid fuel rocket engines.

The main advantage of ac- it required less maintainance The main disadvantage of ac-it can not be stored the main advantage of dc -it required less amount of conductors to transmit and easily stored The main disadvantage of dc-it is more dangerous than ac at high voltage
The Space Shuttle main engines are powered by a combination of Liquid Oxygen (LOX) as an oxidizer and Liquid Hydrogen (LH2) as a fuel. Both propellants are stored in the space shuttle's External Tank during launch. They are fed into the space shuttle's main engines by umbilical lines on the external tank, and then the orbiter's main propulsion system feed lines. The Space Shuttle's main engines can achieve a thrust level of about 512,300 pounds, which is greater than 12,000,000 horsepower.

One of the main advantage of using a Diesel engine as opposed to a regular is that a Diesel engine tends to burn less fuel. They also have very high thermal efficiency.
Google & Yahoo are two main search engines.
Bing, Google and Yahoo are the main search engines.
The two main types of rocket engines are Solid fuel rocket engines and Liquid fuel rocket engines.
The three main classes are the internal combustion engines, steam engines, turbine engines.
You are not specific enough. The main advantage of what? It does not make any sense.
The main advantage of using a web query to get information is the ability to retrieve real-time data directly from a website or online database without manual data entry. Web queries can automate the process of data retrieval, saving time and reducing the risk of errors associated with manual extraction.
main advantage of storing documents in a hierarchy
The main advantage of ECL over TTL is speed.
there is no real advantage. you just have sex.
Portability is the main advantage.
The main advantage is that the patient may not need to wear a cast or brace after the procedure.
