The best aircraft engines for fighters in terms of thrust

The best aircraft engines for fighters in terms of thrust
Impossible to define, which aircraft engine is better, which is worse, because these are complex engineering products, characterized by many different characteristics and designed for different types of aircraft, designed to perform different tasks. Therefore, they can only be compared by individual parameters.. If you select the top three among fighter engines based on their thrust, then it will contain products of Russian and American manufacturers.

Thrust is one of the key parameters of a combat aircraft engine

In aviation, thrust is called force., pushing an airplane in the air. It is opposed by frontal resistance. If the car is flying straight and horizontally at a constant speed, then the thrust will be approximately equal to the frontal resistance.

Most often, thrust is measured in kilonewtons (kN) or kilogram-force (kgf). Roughly one kilogram-force accounts for 10 Newtonian. And if exactly, the 1 kgf = 9,80665 n.

Using this indicator, select the three best engines in terms of thrust. To make things easier, we will compare their thrust by the maximum indicator in afterburner mode.

Engines for the Su-27 family of fighters

Russian fighters Su-27, Su-30 and Su-35 belong to the same family. The Su-27 became the basis for the design of the later Su-30 and Su-35..

The Su-27 combat aircraft uses an AL-31F by-pass turbojet engine with an afterburner. Two such engines are installed on each fighter.. They are also used to equip Su-30 fighters.. Such an engine in afterburner mode is capable of developing maximum thrust 122,6 kN.

A newer Su-35 fighter uses a different engine - AL-41F1S, controllable thrust vector. This product, like the previous, It has a length 4,9 meters and diameter 1,2 m. Despite, that the new unit has the same dimensions, he is able to develop much more traction, than its predecessor. She is already 142,2 kN.

American champion F-22

F-22 fighters, produced in the USA, equipped with Pratt engines&Whitney F119-PW-100. To date, more than 500 units. This product is a twin-shaft engine, equipped with counter rotating high and low pressure rotors.

By thrust, which is almost 155 kN, F119-PW-100 is fully qualified to be the leader among fighter aircraft engines. True with some caveats.

As stated earlier, traction is far from the only characteristic. Therefore, due to the greater mass, the maximum speed, developed F-22, below, than the speed of the Su-35, even though an American develops a lot of cravings, than a Russian.

Besides, as it turned out, F119-PW-100 engines develop their resource faster, than expected. Therefore, the US Air Force is already beginning to experience a shortage of these products..

On the other hand, if the engine life is coming to an end, this indicates their intensive use. And the active use of products indicates that, that he found his place in the American military aviation and is quite satisfied with its characteristics by its users.

Unified Russian aircraft engine

In July of this year, Evgeny Semivelichenko, Managing Director of the Lyulka Experimental Design Bureau at the Ufa Engine Building Software, told RIA Novosti about the start of the development of a new universal aircraft engine for Su-27 fighters, Su-30 and Su-35. Moreover, the product can be installed on any of three types of aircraft without modifying the airframe..

Improved engine performance compared to predecessors is planned, and it will involve the nodes, already used in previous models.

The unification of engines for different types of fighters is a positive factor in terms of the economics of their production.. At the same time, it will become cheaper and easier to service this equipment in parts.

And when the first prototype of the new engine is created, it will be interesting to know its technical characteristics, including developed traction.

The best engine is American 5 generation that stands on the F-22 ALLOWS TO FLY WITH SUPERSONIC SPEED WITHOUT afterburner!
