Pronunciation: [pɹəpˈɛləz] (IPA) 
The word "propellers" is spelled with double "p" and double "l" because it follows the rule of doubling consonants in certain situations. In this case, the consonants are doubled because they come after a stressed short vowel. The IPA phonetic transcription of "propellers" is /prəˈpɛlərz/. The stressed syllable is "pel" which is marked with the inverted "e" symbol. The "z" at the end signifies the plural form of the word.
Propellers are mechanical devices used to generate propulsion or lift by producing a rotational motion in a fluid medium, such as air or water. They are commonly used in various applications, including aviation, maritime vessels, and industrial machinery.
Typically consisting of two or more blades attached to a central hub, propellers operate by converting rotational energy into thrust. As the blades rotate, they create a pressure difference between the forward and rear surfaces. This pressure difference causes the fluid medium to flow faster on the forward-facing side, resulting in a forward or upward force, depending on the application.
Propellers are extensively used in aircraft, where they act as airfoils to provide lift, generate thrust for forward motion, or control the aircraft's attitude. In maritime applications, propellers are used to propel boats, ships, and submarines through water. They may be mounted on shafts driven by internal combustion engines, electric motors, or other power sources.
The design and construction of propellers depend on factors such as the desired speed, maximum efficiency, and the medium in which they will operate. Factors like pitch, diameter, number of blades, and blade shape are carefully calculated and optimized to ensure optimal performance.
Overall, propellers play a crucial role in various industries, providing efficient and reliable propulsion in both air and water mediums.

The word "propellers" has an interesting etymology. It derives from the verb "propel", which comes from the Latin word "propellere". "Propellere" is a compound word consisting of the prefix "pro-" (meaning forward) and the verb "pellere" (meaning to drive or push). So, "propeller" essentially means "something that drives or pushes forward". The term is mainly used to refer to the rotating blades of a device or machine, such as an aircraft or ship, that generates thrust and enables forward movement.
