The JF-17 has a power to weight ratio of 0.99.

Is the engine already being pushed to the limit of what it can deliver or is it possible to make it produce more power to pass that magic 1.00 mark?

we are looking for a better engine to increas the TW ratio. also the block II have planes to be using more composite materials so that the weight will be reduced therefore hopefully the second block of JF17 will have a better TW ratio. now as we ahev planes to undergo so many things to do so it dont think that the current engine can do us any better with the same plane structure. of courese it is not that these upgrades are only aimed at better TW ratio but surely it is an important part of the upgrades!

regards!
 
If its get 1.00 TW Ratio then it can take off like F15 or F22..max climb.
 
using composites, and chinese WS13A engines with 15% more thrust or french engineM88-2. in block2 will help
 
This is how you should not run a program... Foreign input delay, internal delays, no pilots etc etc...

Tejas may skip operational clearance deadline

Ravi Sharma

BANGALORE: Worried over the pace of the indigenous Light Combat Aircraft (LCA) Tejas programme, the Indian Air Force has suggested that the deadline for the fighter’s initial operational clearance (IOC) be postponed.

According to the latest schedules, the IOC is December 2010. But with a number of issues dogging the design and development of the fighter, the postponement was suggested during last week’s ‘monthly review meeting.’ Senior officials from the designers, the Aeronautical Development Agency (ADA), the IAF (including the newly appointed Deputy Chief of Air Staff Air Marshal N.V. Tyagi) and the manufacturer, Hindustan Aeronautics, were present.

Highly placed sources told The Hindu that the software integration of crucial equipment like the Israeli-built multimode radar (MMR) with the aircraft was yet to be completed. The lack of a radar meant that crucial points on the flight envelope were yet to be tested.

The ADA has still not provided HAL with the digital flight control computer and air data computers which have to be integrated into the LCA programme’s Limited Series Production 3 (LSP3) aircraft.

The new LSP3, which was scheduled to make its first flight in June 2008, is now expected to do so only in September.

Both the IAF and the ADA have bemoaned the low sortie generation by HAL. Just 11 sorties were undertaken in April, 24 in May and 23 in June. Officials claim that a minimum run rate of 30 sorties a month is required to meet the present IOC deadline. With this in mind, a plan to prepare two aircraft for flying in the forenoon and one in the afternoon was worked out. But this has not fructified.

HAL officials, however, deny that sortie generation is the primary reason behind the delays. “With two aircraft withdrawn from the flight test programme, we have just five aircraft to generate sorties,” said an official.

“And even the available aircraft are not fully fitted to undertake the flights that are required. We have even painted LSP3 in its new colour [grey] and are ready. LSP4 will have its ground run before the end of July and the fuselages for LSP5 and LSP6 are ready. On six occasions in June while the aircraft was prepared and the weather good, there were no pilots.”

Officials said the IAF was aware of the shortage of test pilots at the National Flight Test Centre (the LCA is flown exclusively by these pilots) and was looking to increase their number.

Why LCA is being discussed in JF-17 thread:whistle:
 
Oneliner? Rhetoric question? Whatever...
 
hey people,china is using multy paylons for missile launch.
is there any chance that PAC will use it for jf-17 ? any news about multipaylons for jf-17?
 
The JF-17 has a power to weight ratio of 0.99.
what is power to weight ratio? Is this TWR? according to my information, JF17's TWR is less than F16's TWR

sir you are right on this, but, this was perhaps because the F16s were primarily designed for the WVR supremacy where sharp turns and all these things helped, however we have all seen that the turn of JF17 was equally sharp to that of a F16, moreover in that vedio the F16 was flying on full military thrust whilw the JF aws not fully operational!
however it do not means that JF do not need a better TWR and the chances of getting it have been discussed.....
better engine
more composite materials etc!

regards!
 
Recent news (October 2008) suggested that PLAAF has decided to acquire some FC-1s (dubbed J-9?) as a low-cost light figher/attack aircraft to replace its obsolete J-7s and Q-5s. Currently FC-1 is undergoing various weapon integration tests.

Plus thunder does it without AB, While the Falcon does all its manv with AB
 
No doubt aircraft with higher TWR can accelerate faster. However, TWR changes as fuel is consumed. JF-17 TWR is 0.95 with full fuel load and with full after burner, compared to F-15C at 1.1 or Mig 29 at 1.15. One wouldn’t know how much fuel and other ordinance each aircraft is carrying when these meet face to face. It is possible that Jf-17 in interception mode and fully loaded MIG 29 have the same TWR at a given point in time. TWR is important but not it is not an ‘end all’ by itself
