The CAC/PAC JF-17 Thunder is a light single-engine multirole fighter plane. The aircraft has been jointly developed by the Pakistan Aeronautical Complex (PAC) and Chengdu Aircraft Corporation (CAC) of China. It was designed to replace the A-5C, F-7P / PG, Mirage III, and Mirage V fighter aircraft in the Pakistan Air Force. The JF-17 can be used for many roles, including interception, ground attack, anti-ship, and aerial.

The CAC/PAC JF-17 thunder can fly with a variety of armaments, including air-to-air and air-to-surface missiles and the 23mm GSh-23-2 twin-barrel Autocannon. The Guizhou WS-13 or Klimov RD-93 turbofan engine gives it a top speed of Mach 1.6. Pakistan wants to form the backbone of the Air Force (PAF), supplementing the CAC/PAC JF-17 thunder at half the cost of the General Air Dynamics F-16 Fighting Falcon. PAF inducted its first JF-17 into its air force in February 2010. In 2015 Pakistan produced 16 JF-17s. As of 2016, Pakistan is believed to have the capacity to produce 25 JF-17 per year. The JF-17 airframe has 58% Pakistani and 42% Chinese / Russian descent.

The Pakistan Air Force plans, by 2017, to include a twin-seater version of the CAC/PAC JF-17 thunder, known as the JF-17B, for both enhanced capability and training. Preparations for the more advanced and technically sophisticated Block III version of the JF-17 aircraft are underway, and its AESA radar, the KLJ-7A, can simultaneously track up to 15 targets.

CAC/PAC JF-17 Thunder Avionics

CAC/PAC JF-17 thunder, an open architecture software, is used. The generals who use the software in the aircraft are written in the ada programming language, whereas JF-17 uses that software to be c programming. Written in the language and f-22 aircraft, which is USA’s same programming language, has been used.

This enables future modifications that if a civilian idea comes into the future, it can be easily implemented in it.

The defense ad system (DAS) of the CAC/PAC JF-17 thunder has many integrated systems such as a radar warning receiver that provides the direction of probability enemy radar, another electronic warfare suite that becomes CAC/PAC. The JF-17 is mounted on the tip of the tail fin of the thunder.

The electronic warfare fair suit is also connected with the missile approach warning system, which protects the aircraft from radar-guided missiles.

The missile approach warning system is mounted around the JF-17 as optical sensors that detect the missile’s rocket and provide 360-degree coverage.

The data that the missile approach warning system has for the incoming inbound missile is shown on the head-up display of the cockpit, and the counter major dispensary systems release decoy flairs to avoid enemy radar and missiles.

The CAC/PAS JF-17 thunder can also be fitted with a self-protection radar jamming pod while carrying on the external head point.

CAC/PAC JF-17 Thunder Radar

The first 42 Pakistani Airforce production JF-17 is equipped with KLJ7 radar, which is a variant of KLJ10 radar, which is used in J-10 then. It is a multi-mode radar and tracks about ten targets in track pile scan mode. And engage two targets semantically.

The operational range, which is said to be 5 meters square for RCS objects, is more than 105 kilometers, so these numbers are classified.

This range is for lookup mode. Where is the range for people down? It is said to be more than 85 kilometers.

It can also be a forward-looking infrared pod (FLIR) according to the mission, and an infrared search and track (IRSC) system can also be installed according to the requirement for the passive target.

China has also developed a mounted helmet site for the CAC/PAC JF-17 thunder, which was prototype tested in 2006.

CAC/PAC JF-17 thunder is equipped with two very high frequency and ultra high-frequency radios, so the high-frequency radio’s capacity is the communication of data linking with ground control centers as well as with AWACS aircraft. Capability is that close of data linking that makes it not as capable of sharing information on network centering work platform, but it is very close to sharing information.

So you can say that the JF-17 thunder is the pilot, which provides very good situational awareness.

Any modern fighter aircraft needs a targeting pod for precision ground attack rolls. Pakistan felt in 2016 that a targeting pod should be put in JF-17, so the pod that was running in their mind at the time was French. Was but Pakistan did a pod test of Turkey in 2017.

CAC/PAC JF-17 Thunder engine

The engine fitted to the JF-17 is the Russian kamov RD93 engine, which is a variant of the kamov RD33 used in mig-29 aircraft, so the position of its gearbox in RD33 Compares has been changed slightly.

The thrust numbers have been increased, but the compromise has been done on its service life, which is only 22 hours, which is very poor as the RD33 engine has a service life of 4000 hours, which is almost half of its life.

CAC/PAC JF-17 thunder engine afterburner Thurst is 5.6 kg newton while as dry thrust is 50.4 kg newton.

In the future, the CAC /PAC JF-17 thunder engine can be replaced with the Chinese WS13 engine; its size is slightly less than the RD93, the weight is 20 kg more, and the thrust difference is 5 kg newton, i.e., It is more than RD93, but it is not the main thing. The main thing is that the service life is more in the RD93 Compares, than the RD93 engine, which has a problem with it is Black Smoke, and the problem is carried forward. Even with the RD93 engine, the current JF-17 has this problem, and it makes this fighter visible in front of the enemy aircraft, which is a big disadvantage.

Airframe and cockpit

The airframe of the JF-17 is of the semi-monocoque structure made primarily of aluminum alloys, with high-strength steel and titanium alloys partially adopted in some key areas. The aerial frame is designed for a service life of 4,000 flight hours or 25 years. JF-17 block 2 uses more composite materials in the airframe to reduce weight. The position and shape of the inlets are designed to give the airflow required for jet engines during maneuvers with high angles of attack.

The mid-mounted wings of the CAC/PAC JF-17 thunder are of cropped-delta configuration. Near the wing, the route is LERX, which produces a vortex that provides additional lift to the wing at higher angles of attack encountered during maneuvers. It incorporates a traditional triangular aircraft-building arrangement, all with a moving stabilizer, single vertical stabilizer, rudder, and twin ventral fin. The flight control system (FCS) includes stability control in the yaw and roll axis and conventional controls with a digital fly-by-wire (FBW) system in the pitch axis. The leading-edge slats/flaps and trailing edge flaps are automatically adjusted during a maneuver to increase turning performance. The FCS of serial production aircraft allegedly consists of a digital quadruplex (quad-redundant) FBW system in the pitch axis and a duplex (dual-redundant) FBW system in the roll and yaw axis.

CAC/PAC JF-17 Thunder

The JF-17’s glass cockpit is covered by a transparent, acrylic canopy that gives the pilot an excellent, all-around field. It has three large multifunction color displays (MFDs) and smart heads-up displays (HUDs), with built-in symbol generation capability. A center stick is used for pitch and roll control, while the hull keeps the paddle under control. A throttle is located to the left of the pilot. The JF-17’s cockpit includes a hands-on-throttle-and-stick (HOTAS) controls. It also has a Pilot Martin-Baker MK-16LE-Zero ejection seat. The cockpit includes an electronic flight instrument system (EFIS) and a wide-angle, holographic head-up display (HUD), with a minimum area of ​​25 degrees. The EFIS includes three color multi-function displays that provide basic flight information, tactical information, and information on engines, fuel, electrical, hydraulics, flight control, and environmental control systems. HUD and MFD can be configured to show any available information. The central MFD is placed at the lowest to accommodate a control panel between it and the HUD.

Up to 3,629 kg (8,001 lb) of ordnance in the JF-17, and fuel can be placed under Hardpoints, two of which are on the wing-tips, four under the wings, and one under the torso.
