JF-17 Thunder Multirole Fighter [Thread 3]

[BATMAN]

At least this part (formulae) is true (not sure about the values used other than gravity):

The Russian-made RD-180 rocket engine (which powers Lockheed Martin’s Atlas V) produces 3,820 kN of sea-level thrust and has a dry mass of 5,307 kg.[citation needed] Using the Earth surface gravitational field strength of 9.807 m/s², the sea-level thrust-to-weight ratio is computed as follows: (1 kN = 1000 N = 1000 kg⋅m/s&#178

At least this part (formulae) is true (not sure about the values used other than gravity):

Typically boosters have hight T/W ratios (>~60) because they have to cause immense acceleration to cut away from earth escape velocity & their burnout time is too small (even measured in seconds)!!

First 4 examples from table

Sustainers and upper level boosters have low T/W ratio & correspondingly greater burnout time
e.g RD-0750 (Application: Alternative for Angara central stage, MAKS.)
RD-0146(Application: Centaur upper stage (Atlas); high performance upper stages for Onega, Proton, Angara launch vehicles.)

just my 2 penny

As per Pshamim Sir

SD-10 Test

Re: JF-17 related discussion: Jan - Sept 2010
Good News for all who have been waiting that SD-10 will be tested by PAF before the end of the year. There was a rumor that it may happen but now it was condirmed that plans have been firmed up. That also means that whatever the issues were with the radar have now been resolved.

Re: JF-17 related discussion: Jan - Sept 2010
Pshamim,

A pilot (Farnborough) told that the tested was done but it would be officially fully certified before end 2010.

Yes i didn't meant its deficient. But many times the SBP are inducted for further testing also.

In our case we had the 4 SBP by end of 2007 and the rest of the 4 had come by 2008, thus we had the 4-8 SBP JF-17s for over 2 years in testing and evaluation before the final batch of of 42 got into production in the order for first 50. So these 8 went through testing and evaluation and pilot training, once fully done, serial production started with some changes being done as per the results of evaluation of the first 8 SBP. take the example of rumors that first eight would be having the KLJ-7 radar, which will be changed to KLJ-10 radars from the 9th JF-17 onwards, what happened in reality is debatable though.

Take the example of your LCA which i believe is now in LSP and the different aircraft coming out in LSP have some changes compared to their prototypes, even the LSPs have some changes with each other.

Here plz view the variants section at the end of this page and see what the LSPs have difference.

HAL Tejas - Wikipedia, the free encyclopedia

So this SBP or LSP is common for further tweaking and evaluation before one final configuration is set and fully tested.

Here is my understandings:

Batch Production- A production system in which a process is broken down to seperate operations that are completed as a batch before moving to the next production stage. Generally all the major parts which make up an aircraft is divided as the phases such as fuselage,tail,wings,landing gear,engine and flight control systems. In JF-17 production, it has divided into 8 (according to MuradK) in PAC.

The term "Small Batch Production" here refers not the prototype thingy used for testing purpose rather the definitive design which has to be delivered (Its already in the squadron).

After all this , Mr.Nabil is claiming that

Small production aircraft do not take part in a full fledge military exercise like Azm-e-Nau..... Anything else you wan to know??

An absurd comment to made with a serving aircraft.

What i stated was in the context of SBP for JFT not for any other fighter and i know this is contrary to the usual practice but then we have seen so many things happening against the usual practice throughout its development from de-coupling of avionics to major re-design of inlets, LERX, airframe and what not, also it took part in Azm-e-Nau after rigorous development and testing for 3 years in Pakistani climate and conditions testing various systems in different regimes and circumstances, the first squadron was inducted in February and immediately it displayed its effectiveness in that exercise. The reason of this hurry was the fact that PAF is feeling really confident about JFT and to such an extent that the planned squadron induction was April and it happened two months earlier. I laugh hard when i see such comments from people like yours but i fail to understand why you are bother so much but then, maybe you should

I saw many Indian members making baseless arguments throughout JFT production to induction and even today such as engine blocked, FCS is hydraulic, radar is obsolete, BVR less and now you come with this? Just how much info you have on this issue Mr.? Please enlighten me if you have something worth mentioning instead of grabbing words and making things more complicated than they really are. I do have an idea what i am talking about so next time try a bit hard to convince or dont jump on something that you have no idea about.

As per Pshamim Sir

SD-10 Test



on pakdef info

It is indeed heartening to see the confirmation of news by Sir Shamim that i was told about a simple software glitch between klj-7 and sd-10a and was rectified after a short while. One more thing that is noted with this radar is the ease of integration of some Pakistani and other non-Chinese weapons and how seem less the procedure was for PAF with this radar. For those who think it is a mediocre radar, its transmitter is more powerful than that of Grifo-S who claims a transmitter of 560 watts, most powerful of entire Grifo lineup

For reference.....

Is it mandatory for a person to reveal how much he gained knowledge about this aircraft to question a foolish comment made by you ?? .

i know this is contrary to the usual practice but then we have seen so many things happening against the usual practice throughout its development from de-coupling of avionics to major re-design of inlets, LERX, airframe and what not,

What are you blabbering here ? PT-04 inducted with a good design changes in China how it support your claims OR you just put here to show off your knowledge....OR contrary to usual practice put aside 10 to 15 aircrafts onlee as up gradation testing bed..

also it took part in Azm-e-Nau after rigorous development and testing for 3 years in Pakistani climate and conditions testing various systems in different regimes and circumstances, the first squadron was inducted in February and immediately it displayed its effectiveness in that exercise.


So ? whats your point.. It may be the same SBP one which you claimed forbidden for practice.

I laugh hard when i see such comments from people like yours but i fail to understand why you are bother so much but then, maybe you should

Laugh hard.. Its also a face saving method..

 

[Dazzler]

You win sir, sleep well. by the way, do let us all know when any further development takes place..

Oh.. those peep , sneak jobs are done by others.
