F22 vs Су37. Their comparison

Requirements for fifth-generation aircraft is quite extensive. The main ones can be summed up in two definitions - stealth and versatility.

Americans have high hopes for the F-22. We have in service is a multi-purpose su-37. And many military experts question. Can he win against F22 Су37?

History of the F-22

The US plans have already been building such an aircraft, which is fundamentally different in its flight characteristics from those aircraft that existed in service.

The air force has formulated the basic requirements for the prospective fighter.

The Car had to have:

• New avionics;
• Engine is running computers;
• Needs to be invisible to means of detection of air targets.

The contest was launched in mid-1986. Work on the creation of new machines were involved in groups of two KB. The conditions of the competition restricted time frame: the design was given 50 months.

Also did not specify the comparison: F22 vs Су37.

And by the beginning of the 1990s, both cars marked "Product of YF-22 and YF Item-23" was ready.

In the design process was done a lot. Consequently immediately rejected the expensive radar, which performs the function of the circular review of a vessel. Also had to refuse from the additional optical and protective systems. Such sacrifices due to the fact that the project went beyond project funding the F-22.

In the Summer of 1991 was won by the machine, in which participated companies such as Lockheed, Boeing and Dynamics.

An Expensive toy?

Probably all remember the expression "weight in gold"? So, these words are very appropriate to the American aircraft F22. Against Су37 (it price we learn later) only the initial cost of "American" was above 4.5 times. But if we take into account indirect costs, the price of the "superweapon" reached the mark of 350 million dollars!

How to create a su-37

The Decision on the creation of the su-37 was adopted in 1986 and the MIC under the Council of Ministers of the USSR.

The First prototype was created taking into account the realities of the cold war - Russian "Terminator" vs "Raptor" (USA).

The Plane was created with the involvement of the design Bureau named after P. Sukhoi, and named after A. Cradles (design Bureau "Saturn"). Also been involved in other institutions and organizations. Among the developers was the French firm "Sexton avionik"

Experimental flights, which were tested powerful new engines AL-37ФУ, was held in the beginning of 90-ies. The engine is created the increased thrust and rotary nozzles.

The Results of the tests were so successful that accelerated the creation of a new aircraft.

But then came the August 1991, and was followed by a series of events – the collapse of the Soviet Union, the elimination of Minaviaprom and, as a consequence, was ceased the funding. All this led to the fact that the program for creating advanced aircraft was phased out and happily forgotten.

So opponents of the US in those days could only rejoice in the fact that in the virtual war Raptor vs su-37" they have lost as serious rival.

Design features of the F-22 Raptor

At the service of the F-22 Americans, to reduce visibility to enemy radar, has decided to put all the weapons inside the plane.

The seats on the wings of the aircraft for placement of the attachment of weapons on the plane, but in order to disguise they are not used.

The Use of composite materials in the hull of the flying machine (accounting for 40% of total coverage) has allowed to reduce the overall weight of the structure. In addition to weight reduction, the use of such materials allows to increase the resistance of structure to overheat.

Also the body of the plane was covered with a material, which successfully absorbed the radio waves. With the same purpose (to increase visibility) the canopy and pilot compartments under the chassis was made in saw-tooth form. These forms were allowed to efficiently dissipate the reflected electromagnetic wave from the radar of the enemy.

The parameters of stealth, of course, the F22 wins (against Су37). This also helps the diamond shape of the wing.

Powerplant Raptor is a combination of two engines of P&W F119-PW-100, which are characteristic of this plane of the flat jet nozzle. The use of ceramic materials in their construction can significantly reduce the visibility of the machine in the IR spectrum.

With engine power of 11,000 kgs, the plane can easily overcome the barrier of the speed of sound. And this option boasts a limited number of combat vehicles, including the F-22 and su-37 .

Features of the su-37

The Russian rival the f-22 is equipped with automated control system. It moves absolutely all of the aerodynamic regulation, and turn the engine nozzle with the control knob.

The Electronic system automatically provides the protection of a fighter based on not only his weight, but the selected flight regime. The aircraft is equipped with an automatic output mode "corkscrew".

The Radical transformation undergone cockpit. The Central control knob has been replaced on the side. And levers engine control replaced by a strain gauge, which directly improved motor control through kupela.

What is the result? To increase the precision of piloting, improved control of the aircraft when exposed to pilot the big overloads. The aircraft was supplied with an integral fly-by-wire control system, which automatically changes the thrust vector of the power plant. This solution allowed us to give the aircraft maneuverability at low and near-zero flight speeds, which has a positive effect if you compare F22 vs Су37.

Changed the information field on the dashboard. Before the pilot now has four multi-function LCD monitor, developed by the French firm "Sexton avionik". Monitors are protected from the solar flare, now the pilot can see the basic dynamic parameters in all weather conditions.

An Additional indicator is also installed on the windshield that displays the necessary information.

Increasing the comfort level of the cabin has increased tolerance of overload for the pilot, and this, in turn, gives you the opportunity to fully realize all the combat capabilities of the combat vehicle su-37 vs F-22 even the line pilots.

How much is su-37

According to the results of extensive market analysis conducted by the developers, it was found that potential buyers of the su-37 presents range from 24 countries. The number of travelers from different countries already is 1 000 articles!

Such strong interest is not only unique characteristics, but also attractive cost of the aircraft on the international market, especially in comparison (F22 vs Су37) does not exceed $30 million.

Arms "Raptor"

The Combat power of the f-22 Raptor consists of 20-mm cannon M61A2 Vulcan class for 480 shots. The machine also can carry on wing pylons or six missiles "air-air" AIM-120C AMRAAM and two missiles of the type AIM-9M Sidewinder.

The Plane carries the bomb load, which consists of air bombs and JDAM type guided bombs, type GBU-39. At the same supersonic speed does not interfere with the aircraft to make an attack.

Combat equipment su-37

Compare F-22 and su-37 should start with small arms and cannon of the Russian fighter. It consists of rapid-fire single-barrel 30-mm cannon GSH-301, which is located in the right wing and has a capacity of 150 cartridges.

Complements oneoriginally missile and bomber gear. It is placed in the beam holder 12 in points:

• 6 – under the outer wing panels;
• 2 - under the wing tips;
• 2 – under the engines;
• 2 - under zernoprom.

The Aircraft can be equipped with:

• 8 guided missiles "air-air";
• 10 medium-range missiles with active homing;
• 6 missiles for close air combat, R-73;
• 6 bombs KAB-500Kr with a guidance system.

The use of missiles KH-29L, S-25ЛД and X-59M fighter is equipped with containers of weapons control.

All unmanaged aviatourne type "air-land" collects a total mass of 8 tons. It can submitted by:

• 16 bombs FAB-500M54;
• 14 bombs FAB-500M62 FAB-500M62;
• 14 incendiary tanks ZB-500;
• 48 bombs ofab-100-120;
• 8 containers kmgu;
• 120 unguided rockets C-8 (6 blocks B-8М1);
• 30 rockets s-13 (6 units UB-13);
• 6 rockets s-25 (PU-25).

Long-range detection presents pulse-Doppler radar with fixed antenna array and on-Board radar to the rear view.

The Sighting system of the su-37 consists of a thermal imager, which is combined with a laser rangefinder–designator. The installation allows to detect and maintain multiple objectives.

"Jumping" su-37

Domestic "Drying" has acquired so high fighting qualities that they should be discussed separately.

The Aircraft can change the slope angle of up to 180° to endure it for as long as is the rocket. The combat vehicle are no restrictions at all angles of attack. And due to the increase of the lift force have the opportunity to perform a new aerobatics:

1. Turn the plane 360°.
2. Fire Forced a reversal.
3. Rotate on vertical.
4. Perform "Cobra" at the corners 150° - 180°.
5. The Coup when you run the figures "bell".
6. The Coup, with the loss of altitude as 300-400m.

With such possibilities of maneuvering extremely beneficial looks of the su-37 "Terminator" (against the F-22 "Raptor"), which provides him an advantage in a dogfight.

Early warning System on F-22

On-Board equipment consists of two computers installed CIP, each of which is equipped with 66 modules. They consist of a 32-bit processor i960.

On Board the American aircraft has radar type AN/APG-77. The unit includes a phased array antenna, which consists of 2000 elements, allowing both to receive and emit signals.

With the help of radar target detection occurs at a range of 225 km Inas on-Board radar detects targets at a distance of 525 km.

Self-protection system prevents the interception of radar signals of the enemy. Such a system is the F-22 (compared to su-37) helps to find the target, so the enemy does not notice this using your equipment.

Experts doubt?

Currently, the U.S. military specialists highly doubt its air superiority.

And this is no coincidence. Access to the scene of fighting in Syria, the new Russian aircraft has shown the world the power of Russian weapons!
