This is the case on many large aircraft such as the 747, C-17, KC-10, etc. If you are on an aircraft and you hear the engines increasing in power after landing, it is usually because the thrust reversers are deployed. The engines are not actually spinning in reverse, as the term may lead you to believe.
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Aircraft using power components are referred to as powered flight . [ 1 ] Most aircraft engines are either piston engines or gas turbines , although a few have been rocket powered and in recent years many small UAVs have used ...
The use of a reduction unit is common in the construction of experimental homebuilt aircraft when automotive engines may be used. These engines, in addition to their lower cost, typically have less displacement than purpose-built light aircraft engines and develop peak power at high revolutions per minute (rpm), typically above 4,000 rpm ...
Constant speed drive for Boeing 727, made by Sundstrand Corporation. A constant speed drive (CSD) also known as a constant speed generator, is a type of transmission that takes an input shaft rotating at a wide range of speeds, delivering this power to an output shaft that rotates at a constant speed, despite the varying input.
Mockup with compressor and turbine cutaway. After the budget of NASA on aeronautics research was severely cut at the start of 2006, Pratt & Whitney committed to spend $100 million a year on the geared turbofan (GTF) development for the next generation of single-aisle airliners, focused on the 25,000–35,000 lbf (110–160 kN) thrust range.

If aircraft performance were to increase beyond such a barrier, a different propulsion mechanism was necessary. This was the motivation behind the development of the gas turbine engine, the most common form of jet engine. The key to a practical jet engine was the gas turbine, extracting power from the engine itself to drive the compressor.
And there are certain parts of the profile of the takeoff, cruise and landing where the aircraft is more vulnerable to that because of the speed of the engines or the proximity to the ground.
Aircraft that regularly operate in icing conditions have systems to detect and prevent ice forming (anti-icing) and/or remove the ice accumulation after it has formed (de-icing). This can be achieved by heating the spaces in internal structure with engine bleed air, chemical treatment, electrical heating and expansion/contraction of the skin ...
