JF-17 “Thunder” fighter or CAC FC-1 Xiaolong jets

The PAC JF-17 Thunder (Urdu: جے ایف-١٧ گرج‎), or CAC FC-1 Xiaolong (Fierce Dragon; Chinese: 枭龙; pinyin: Xiāo Lóng), is a lightweight, single-engine, multi-role combat aircraft developed jointly by the Pakistan Aeronautical Complex (PAC) and the Chengdu Aircraft Corporation (CAC) of China. The JF-17 can be used for aerial reconnaissance, ground attack and aircraft interception. Its designation “JF-17” by Pakistan is short for “Joint Fighter-17”, while the designation and name “FC-1 Xiaolong” by China means “Fighter China-1 Fierce Dragon”.

The JF-17 can deploy diverse ordnance, including air-to-air and air-to-surface missiles, and a 23 mm GSh-23-2 twin-barrel autocannon. Powered by a Guizhou WS-13 or RD-93 afterburning turbofan it has a top speed of Mach 1.6. The JF-17 is to become the backbone of the Pakistan Air Force (PAF), complementing the General Dynamics F-16 Fighting Falcon whose performance it roughly matches, at half the cost. The PAF inducted its first JF-17 squadron in February 2010 and five years later 54 units were in service, and 96 units were on order, to be delivered by the end of 2018.

The airframe is of semi-monocoque structure constructed primarily of aluminium alloys. High strength steel and titanium alloys are partially adopted in some critical areas. The airframe is designed for a service life of 4,000 flight hours or 25 years, the first overhaul being due at 1,200 flight hours.  Block 2 JF-17s incorporate greater use of composite materials in the airframe to reduce weight.

The mid-mounted wings are of cropped-delta configuration. Near the wing root are the LERX, which generate a vortex that provides extra lift to the wing at high angles of attack encountered during combat manoeuvres. A conventional tri-plane empennage arrangement is incorporated, with all-moving stabilators, single vertical stabiliser, rudder, and twin ventral fins. The flight control surfaces are operated by a computerised flight control system (FCS), which also adjusts the slats/flaps for improved manoeuvrability. Up to 3,629 kg (8,001 lb) of ordnance, equipment, and fuel can be mounted under the hardpoints, two of which are on the wing-tips, four are under the wings and one is under the fuselage.

Cockpit

The man-machine interface of JF-17 Thunder is kept very simple and flexible at the same time too. The cockpit consists of three Multi functional displays (MFDs) supported by a smart Heads Up Display (HUD). The symbology and functionality of the controls is kept very much similar to SAAB’s Gripen aircraft – an aircraft evaluated by PAF in the past. Implementation of HOTAS (Hands On Throttle-And-Stick) is visible in the design. The commonalty of the cockpit helps in decreasing time and training costs thus making a speedy fighter conversion to the aircraft.

Engines

The RD-93 is known to produce smoke trails. The Guizhou Aero Engine Group has been developing a new turbofan engine, the WS-13 Taishan, since 2000 to replace the RD-93. It is based on the Klimov RD-33 and incorporates new technologies to boost performance and reliability. A thrust output of 80 to 86.36 kN (17,980 to 19,410 lbf), a lifespan of 2,200 hours, and a thrust-to-weight ratio of 8.7 are expected. An improved version of the WS-13, developing a thrust of around 100 kN (22,000 lbf) (22,450 lb), is also reportedly under development.

THE JF-17B COULD BE THE FOUNDATION OF THE BLOCK-III: Here

Excerpt

It would be erroneous to argue that the JF-17 is not hampered by its drawbacks, but it would be equally disingenuous to argue that there were feasible and accessible alternatives. The JF-17’s baseline design – i.e. the Super-7 – was frozen at a time when Pakistan was sanctioned by the U.S., which in turn resulted in the non-delivery of 71 Lockheed Martin F-16A/B Block-15s. In the absence of accessible alternatives, the only alternate avenue for the PAF would have been to retire aging A-5s, F-7Ps and Mirage III and 5s without enough replacements, thereby causing a sharp downfall in fleet size.

The JF-17 was to return to the drawing board anyways (to accommodate for emerging technology trends – i.e. Block-III), but the cost of its absence would have been buying costlier imports. Since 18 F-16 Block-52+ cost $1.4 billion U.S., the alternative (in the 2000s and 2010s) would have, at best, been another one or two new F-16 squadrons. The PAF tried to offset the design limitations with relatively good Western subsystems and avionics, most notably from Thales, but this too fell through due to cost as well as Paris’ desire to reinforce its efforts to sell the Dassault Rafale to India.

Ultimately, the PAF proceeded with the JF-17 as-is, and successfully supplanted its A-5s, F-7Ps and Mirages. In addition, the JF-17 emerged as a credible air defence compliment to the F-16s, resulting a doubling of network-enabled and BVRAAM-capable fighters in the PAF (to 150+ fighters). It also increased the number of fighters capable of deploying stand-off range air-to-surface munitions, especially since the F-16s have yet to be equipped with such munitions. In 2015, the PAF confirmed that the JF-17 was cleared for using the C-802 anti-ship missile and Mectron MAR-1 anti-radiation missile (for engaging ground-based radars).[6] In March 2017, the PAF celebrated the successful integration of the Global Industrial & Defence Solutions Range Extension Kit, a precision-guided glide-bomb kit (providing 50-60 km in range) for Mk-8x-series general purpose bombs.

The JF-17 was also accompanied by other important gains. Besides being a fighter the PAF could freely equip and configure, it also enabled Pakistan Aeronautical Complex (PAC) to build a strong local supply channel to support the fighter. This began with merely assembling kits from China, but by 2015, PAC was responsible for manufacturing 58% of the fighter (with AVIC providing the remaining 42% under the original workshare agreement).[7]

The local channel also enables the PAF to support the JF-17 using domestic currency and labour costs, enabling the fighter’s operational costs to be more affordable than imports. PAC is also serving a vital role in being the supplier of the JF-17’s electronics, which it is manufacturing under co-production or licensing agreements. Not only are Chinese systems being produced under license, but several Western subsystems are also being built at PAC (under co-production deals).

While the PAF opted to induct the JF-17 Block-I and Block-II, it was fully cognizant of the capabilities found on and expected of contemporary high-technology fighters. For the JF-17, the PAF may have pushed the bulk of those requirements to the forthcoming JF-17 Block-III. Granted, the slated subsystems – such as the active electronically-scanned array (AESA) radar and HMD/S – would be significant upgrades, but the JF-17B seems to suggest that the Block-III will be more than just tacking new equipment to an existing design. The design itself may see several key alterations.

The swept-back vertical stabilizer of the JF-17B is housing components for a new three-axis fly-by-wire system.[8] If this is replacing the hybrid flight control system of the Block-I/II, then it may mean a reduction in weight as well as added net internal space. Interestingly, a CAC representative (Zhu Zeng) was quoted saying in 2013 that while the JF-17 Block-I was using a hybrid flight control system, CAC did have a fully digital flight control system it could develop in two years.[9] This may have been put into the JF-17B.

Externally, the JF-17B is larger than the JF-17 Block-I/II. The JF-17B has an enlarged nose to accommodate an AESA radar, but there are other airframe changes as well. AVIC’s purported JF-17B brochure states that the JF-17B’s wingspan is a half-metre longer than that of the JF-17 Block-I/II (9.5 m vs. 9.0 m[10]). It is also slightly longer than the Block-I/II (14.5 m vs. 14.26 m[11]). The lengthened wingspan may indicate an increase in payload, which is one of the JF-17 Block-III’s additions (Aviation Week – subscription required). The JF-17B airframe may also been built differently than the Block-I/II, at least in terms of materials (see below).

If this is a representation of greater composite materials usage, then this could be indicative of further weight reduction. It will be interesting to see if relaxed stability and lower wing loading were also incorporated into the design, especially with the presence of a digital fly-by-wire system. This would help improve the JF-17’s maneuverability.

The tail/engine exhaust area has also been altered, though it is unlikely that this is indicative of an engine switch at this time. The PAF did express interest in a new turbofan engine – the RD-33MK and WS-13. Either one of these engines would improve the JF-17’s fuel efficiency, maintenance costs, and thrust-to-weight ratio (TWR). As per Alan Warnes (via Aviation Week – subscription required), an engine switch will likely happen, though it is not known if this is slotted for the JF-17 Block-III or for later builds.

The PAF was finalizing the Block-III’s design in 2015, which was also around the time the PAF confirmed that the JF-17B will be developed and produced. Since the JF-17B itself was a new program, it is possible that the JF-17B and JF-17 Block-III are connected. Seeing the additional changes, the JF-17B is evidently a separate stream from the JF-17 Block-I/II, and it would make sense to scale the cost of developing the JF-17B to the JF-17 Block-III. Not scaling the JF-17B’s development to the Block-III would mean isolating the JF-17B as a different aircraft, which would not be cost-effective for end-users.

      I’m not surprise that China & Pakistan is not doing a Road show to showcase the JF17 to those small to Middle sized countries who are on a tight budget. Heck, even Laos & Cambodia would be prime candidates for the JF-17.

    Yes Gripen is more expensive than SU30 because the Thai package included huge amount of missiles. 12 Gripen plus 2 EAW Saab 340 and 2 Saab 340 came to about USD1.2 billion. Before they chose the Gripen they were looking at SU30s but the RTAF have a dislike to large fighter planes.

        The aim with the JF-17’s design was to provide a skilled pilot with a chance of success, even against aircraft that cost double the price.

        Take the SU-30. It has a much bigger airframe and can carry more fuel and weapons. But it’s large size gives it a *HUGE* RCS(Radar Cross-Section, meaning it’s easier to detect, even from longer ranges). So there’s always a trade-off, the JF-17 design went for a smaller airframe, but the weapons and avionics it packs are pretty comprehensive.

        Take for example it’s radar – the NRIET KLJ-07. It’s very similar to the J-10’s radar design, only the sender/reciever dish is smaller. It has comprehensive radar-modes for many different situations, including sea-targeting, “beacon mode”(for homing in JF-17s or other friendly aircraft towards a high-value target, tracking multiple air targets, track-while-scan, etc. So the little warplane’s functions have been thought through pretty thoroughly.

        Pakistan faces a much larger foe(India), and we’ve had multiple wars over Kashmir(disputed region the British left, all of Pak’s rivers can be controlled from there). The Airforce is trained to go up against numerically superior enemies, so the JF-17 really needed to deliver. The Pak Airforce also flies the latest American Block-52 F-16s, and we’ve had demonstrations(inside Pakistan as well as Airshows in Turkey, Britain, France and Dubai) where the JF-17 showed itself pretty evenly-matched against the latest F-16s.

        As I said, it packs enough power to give a well-trained pilot a fighting-chance even against costlier or bigger planes.

        That’s why I see the JF-17 fill a niche for places such as Africa, Central America and South America. It’s those places who can’t afford Western or Russian prices.
