"The latest news (March 2013) suggested that the further improved FC-1 04 prototype just flew, possibly powered by a WS-13 turbofan engine."

Wanted to ask If ever JF-17 comes with framelss Bubble canopy like of F-16/F22/J20 .If not why? what are challenged to it as it really gives an aeroplane quite a view+ pilot has 360 view .

There is a difference between a bubble canopy and frameless. A bubble canopy is one that literally sticks out of the iarcraft like a bubble to provide all round view. The F-86 had a bubble canopy.

A frameless canopy is one where the entire canopy is one big transparency. While this is great, it also means that the canopy has to be very thick and strong to support its own load and survive accidents such as bird strikes; this also means that it takes a lot more effort and finesse to form the canopy. A thicker canopy means extra weight on the aircraft, the F-16 canopy is one of the heaviest canopies for an aircraft in its class and costs more. By contrast, the sort of canopy the JF-17 has only needs the front portion to be thick to survive a bird hit ...while the rear of the canopy can be lighter and easier to form.

Nice explanation .Framless canopies do offer wider advantages then conventional canopies other wise with all tech/sensors in latest fighters like F22/J20 shoudnt have them .Considering Pak Fa it has again frame canopy any one care to explain whats the advantage and disadvantage .In terms of weight i guess couple of extra pounds wont hurt considering weight of frame is also subtracted in case of framless canopy

There are trade-offs involved here. First in the weight. Second is the cost. Third is the available power in case drag increases.

For all three reasons, what we have for now should suffice. Any resources available should go for improving sensor-based situational awareness, TWR, ECM, etc... Moreover Helmet Mounted Targeting Systems are a lot more important than a frameless canopy and would probably mean more in a dog fight. We have yet to implement HMTS solution in JF-17.

Frameless canopy may happen, but it is likely not a priority at this time.

Why go far, look at our own beloved Eff Sola

First of all, its just burnt oil stains, not oil rust.............
here is a pic of an F-14

.
Ohh I forgot to mention one important aspect of all jet engines.
Bearing are sealed with compressor bleed air. Upon engine shut down, scavenge pumps are suppose to suck oil back to the sump. Sometime they don't do it properly or on time, and as a result excess oil drips into compressors and engine compartments where they have drain holes that are vented to atmosphere. This can also be a possibility why these engines are "running dirty"

The JF-17 can carry a variety of missiles and bombs, including air-to-air and air-to-surface missiles, supplemented by a 23/30 mm GSh-23-2 twin-barrel auto cannon. It is powered by a RD-93 afterburning turbofan, and has a top speed of Mach 1.6. The JF-17 is slated to become the "mid-tech" backbone of Pakistan Air Force (Pakistan Air Force), complementing the few "high-tech" surplus F-16s with the J-10Bs order delayed indefinitely. The JF-17 is expected to fill the duties of aerial reconnaissance, ground-attack and interception.


Pakistan Air Force has already started induction, and has plans to induct around 250 units. The JF-17 will replace Pakistan's ageing fleet of A-5C, Mirage-III, Mirage-V, and F-7P/PG by 2015.
Avionics
Aircraft
The software written for the Pakistan Air Force JF-17's avionics totals more than one million lines of instructions, incorporating the concept of open architecture. Rather than using the Ada programming language, which is specially optimized for military applications, the software is written using the popular civilian C++ programming language to better use the large number of civilian software programmers available. The redesigned PT-04 prototype JF-17 had more advanced avionics than its predecessors, which are included on the production version of the Pakistan Air Force jets.
Tactical
The communication systems of Pakistan Air Force comprise two VHF/UHF radios, one of them having capacity for data linking. The data link can be used to exchange data with ground control centers, airborne early warning and control aircraft and other combat aircraft also equipped with compatible data links. Using this ability of data linking it can also communicate with recently inducted state of the art main battle tank Al Khalid Tank in Pakistan army. The ability to data link with other "nodes" such as aircraft and ground stations allows JF-17 to become part of a network, improving the situational awareness of the pilot and other entities in the network. Data linking is an essential part of the main battle systems. Modern warfare is solely based on effective co-ordination between different armed forces. Therefore this system is very useful for today’s battle ground.

Cockpit Of JF-17 Thunder Of Pakistan Airforce (PAF)​

The JF-17 has a defensive aids system (DAS) made up of various integrated sub-systems. A radar warning receiver (RWR) gives data such as direction and proximity of enemy radars to the pilot and electronic warfare (EW) suite, housed in a fairing at the tip of the tail fin for greater coverage that interferes with enemy radars. The EW suite is also linked to a Missile Approach Warning (MAW) system to help it defend against radar-guided missiles. The MAW system uses several optical sensors mounted on the airframe (two of which can be seen at the base of the vertical stabilizer) that detect the rocket motors of missiles and gives 360 degree coverage. Data collected by the MAW system, such as direction of inbound missiles and the time to impact, is also shown on the cockpit displays and HUD to warn the pilot. A counter-measures dispensing system releases decoy flares and chaff to help the aircraft evade enemy radars and missiles. The DAS systems will also be enhanced by integration of a self-protection radar jamming pod which will be carried externally on one of the aircraft's hard points.

Propulsion And Fuel System
The JF-17 is powered by a single Russian RD-93 turbofan engine, which is a variant of the RD-33 engine used on the Mig-29 fighter. The engine gives more thrust and significantly lower specific fuel consumption than the turbojet engines fitted to older combat aircraft being replaced by the JF-17. The advantages of using only one engine are that both maintenance time and cost are significantly lower than twin-engine fighters. A thrust-to-weight ratio of 0.99 can be achieved, with full internal fuel tanks and no external payload. The engine's air supply is provided by two bifurcated air inlets. However the RD-93 is known to produce smoke trails.

Weaponry
JF-17 can be armed with up to 3,629 kg (8,000 lb) of air-to-air and air-to-ground weaponry, as well as other equipment, mounted externally on the aircraft's seven hard points. One hard point is located under the fuselage between the main landing gear, two are underneath each wing and one at each wing-tip. All 7 hard points communicate via a MIL-STD-1760 data-bus architecture with the Stores Management System, which is stated to be capable of integration with weaponry of any origin. Internal armament comprises one 23 mm GSh-23-2 twin-barrel cannon mounted under the port side air intake, which can be replaced with a 30 mm GSh-30-2 twin-barrel cannon.

Simulator Of JF-17 Thunder Of Pakistan Airforce (PAF)​

Active radar homing BVR AAMs can be deployed once integrated with the on-board radar and data-link for mid-course updates. The Chinese PL-12/SD-10 is expected to be the aircraft's primary BVR air-to-air weapon, although this may change if radars of other origin are fitted. Short range infra-red homing missiles currently integrated include the Chinese PL-5E and PL-9C, as well as the AIM-9L. The PAKISTAN AIR FORCE is also seeking to arm the JF-17 with a modern fifth generation close-combat missile such as the IRIS-T or A-darter. These will be integrated with the HMS/D as well as the radar for targeting.

AESA radar is in development for Block III not II.

Klj-7v2 is the standard with 130km range(against 5m2 RCS) and also having some other improvements
