New engine being designed for fifth-generation Russian fighter aircraft

By Nikolai Litovkin, Russia Beyond the Headlines   |   Nov. 28, 2016 at 10:20 AM

The United Engine Corp., part of Rostec state holding company, successfully conducted the first ground-based ignition of the second stage of the engine for the Prospective Airborne Complex of Frontline Aviation (PAK FA T-50 aircraft).

In order to carry out the testing, gas generators had to be prepared for it, in addition to the demonstrator engine.

What is the PAK FA flying with now?

Currently, the PAK FA is using a first stage engine, a modernized Al-41.

According to Pavel Bulat, avionics specialist and head of the Kupol Group of Companies, the AI-41 is an updated version of engines used for the Su-27, Su-30 and other models in that series.

“The engine for the T-50 was significantly upgraded from the original models, incorporating the latest control system, compressors, etc. Nevertheless, it still falls short of the fifth-generation model, and is very noticeable on radar screens,” he said.

The new second-stage engine is one of the most advanced in the world, said Bulat. It enables the T-50 to accelerate to supersonic speed, and maintain that velocity throughout the flight, without using afterburners.

“The speed will be as much as Mach 1.6 (about 1,200 mph), depending on the terrain over which the flight is taking place. The engine will also significantly improve the stealth properties of the PAK FA, thanks to the use of new composite materials,” said Bulat.

The designers expect to start testing the new engine on fighter jets in 2018 and for the motor to be fully integrated in 2020.

“In addition to the engine, a radar station also needs to be modified, and engineers need to remove the last deficiencies in the airframe concept, which, among all the aircraft flying today, is the most modern in the world,” said the analyst.

New fighter’s weapons: 30-mm cannon

The firing unit consists of one of the lightest cannon in its class, the 9-A1-4071K, which is designed to destroy armored vehicles or armored enemy targets. During one flight, the pilot can shoot 150 rounds from the 30-mm cannon.

This new weapon is a modified single-barrel GSh-301 aircraft cannon, used in Russian fighters and bombers.

Aircraft bombs

The future T-50 fifth-generation fighter will also carry high-explosive and volume-detonating bombs, Sergey Rusakov, general director of the Techmash Group, announced on Sept. 22.

Rusakov said they are now considering high-explosive incendiary OFZAB-500 aviation bombs for the PAK FA, and volume-detonating ODAB-500PMV, which are currently being used in Russian operations in Syria. Engineers have produced a set of warheads for future tests.

Operational principle and the use of bombs in Syria

According to the rearmament program, Russian Armed Forces will receive a batch of 12 T-50 fighters before the end of this year. A new contract for the supply of fifth-generation aircraft will be discussed with the Ministry of Defense at the end of 2016, after which the War Department will decide how many new aircraft are needed.

Competing with the Raptor

The newest Russian fighter aircraft was produced as the main competitor to the F-22 Raptor. The American stealth fighter distinguished itself during the Iraq War.

“The T-50 will go into serial production much later than the Raptor. This allows us to take into consideration all the pros and cons of the existing aircraft when constructing our own fighter. A similar situation existed when we were working on the multipurpose fourth-generation Su-27 fighter. The prototype of that domestic aircraft came out much later than the American F-16, and took into account the shortcomings of its precursor. As a result, the domestic Sukhoi was able to beat the ‘American,’ in terms of combat characteristics,” Vadim Kozyulin, professor at the Academy of Military Sciences, told RBTH.

The expert noted that the T-50 would be able to use the full range of existing high-precision air-to-air missiles, as well as all precision-guided munitions.

“As part of the ‘stealth’ concept, special missiles for the PAK FA are being developed, with a square cross section that will allow more warheads to be carried in hatches during combat missions,” Kozyulin added.

There were test firing 9A1-4071K aircraft cannon for the Russian fifth generation fighter T-50 (PAK FA) for scientific test range aircraft systems, located near the village of Faustovo Moscow region.

 Aerogun tests were on the test bench, loading 30-mm ammunition in the input tray, and test firing, according to “Rossiyskaya Gazeta “.
It is known that the gun 9A1-4071K for the Sukhoi PAK FA (PAK FA) has been developed by specialists of JSC “Instrument Design Bureau” in late 2014. Because open source is known, that it is an upgraded version of the high-velocity gun GS-30-1.

The gun is ideal for aircraft: its weight of only 50 kilograms, it is considered to be the easiest in the world of 30-millimeter cannon. Unique automation scheme has allowed the base to give 9A1-4071K highest for this type of weapon rate per barrel – up to 1,800 rounds per minute. Feature of the gun is also a stand-alone system vodoisparitelnogo cooling barrel. Its principle of operation is simple: the gun in the casing is water, which is heated in the barrel (during firing) is converted into steam.

Fire from the new gun will be conducted high-explosive-incendiary projectiles and armor-piercing tracer shells, capable of striking even lightly armored ground, surface and air targets. On ground targets gun is effective when shooting at a distance of 1800 meters, in the air – to 1200. Previously 9A1-4071K gun was tested in a multi-purpose fighter Su-27SM. T-50 (PAK FA project) – a fifth-generation aircraft equipped with a fundamentally new avionics suite and promising radar with a phased antenna array. Source gadgetstyle.com.ua

High-explosive incendiary bomb aviation OFZAB-500 was established use in high speed with low altitudes against manpower and easily vulnerable field installations, warehouses and fuel depots. The bomb is intended to replace in the Russian Air Force obsolete FOZAB-500. It is used at altitudes of 300 – 20,000 m at speeds of 100 – 1200 km / h.

OFZAB-500 allows the wearer to carry out maneuvers with large congestion. The bomb can be used on a large number of combat aircraft of Soviet and Russian-made MiG-21, MiG-27, MiG-29, Su-17, Su-22, Su-24, Su-25, Su-27, Tu-95, Tu -16.

Bomb manufactured by the Russian company basalts. Furthermore, the term thermobaric air bomb can meet even the names vacuum bomb, fuel, bomb, aerosol bomb, v detonujúca bomb or a high-explosive bomb.

The bomb is designed to control industrial zones, unprotected or protected by live force (eg. In enclosures, tunnels, caves), nepancierovanej technology and military equipment. The bomb is scheduled for troop (front) airplanes and helicopters. It can be used for the destruction of anti-personnel mines and anti-tank.Planes can toss a bomb from a height of 200 to 12,000 m at speeds of 500-1500 km / hr.
