JF-17 Thunder Multirole Fighter [Thread 5]

I do take your point I would however refer you the the following:

Officials refused to comment directly on the two-seat variant's potential performance other than to say that would be only "slightly less" capable in most parameters. They said that the twin-seat FC-1 compensated for the loss of fuel space - and related range

New, not improved, less capable? Novel Marketing you have to admit

I think that was lost in translation. What he probably meant was that some parameters like speed and fuel capacity and T:W ratio would be affected only in a minor way - while offering other advantages like I mentioned above.

Just Photoshop images of an aircraft that does not exist at present. Logically speaking, they are simply speculative in nature, in the realm of fantasy just now.

l thought that the cost of the retractable probe was a factor in the decision making loop of the PAF. Now people want to insert a retractAble probe in a tank which might have to be jetisoned in a war scenario. If we are going along those lines then we should be thinking of CFTs
Araz

Inserting a Retractable Probe or a fixed probe in aircraft costs more. CFTs not possible, current Bulkheads cannot support them.

If I base it on that, and the various definition of both form and skin friction.. THEN.. the increase in height of the cockpit area due to the second seat should also factor in form drag. So If I understand you right then the required length of the spine to is to reduce skin friction and not form drag which is unaffected(??) due to the change in design?

Rear seat increase form Drag. Length of the spine and height increases skin friction drag.

because it would screw up the weight and balance of the aircraft.
And also you wouldn't be able to carry more weapons. The whole point of mid-air fueling is to free up the space being used by fuel tanks.
Maybe that's why it just remained to "research" phase and never got through.



pictures, or it never happened. That's the rule I go by now.

Weight and Balance shift should not be significant. Such things are designed to keep the weight change to a minimum. Flight controls are designed to cater for some imbalance (the aircraft can adjust flight controls to cater for asymmetric station loadings).

The tank with retractable probe can hold 340 Gallons of fuel, the one without the probe holds 370 Gallons of fuel.

And how would you re-fuel in real war scenario if the fighter has dropped his tanks for WVR fight?

Tanks are only jettisoned for dash (or emergency landing). Dash only done after completing mission.

And you are right refueling would not be possible for air to air configuration aircraft.

So this tank has its downsides... Agreed

Enough to scare you... and BTW thanks for clarifying promptly.

Scare me, huh? Like seriously?
More likely that I'll be scared when pigs will fly........

This is ugly I hope this design is not finalized

This is ugly I hope this design is not finalized

Ugly only if it is destined for a beauti competition...

What is interesting is the compact design, a single piece stretched acryllic canopy instead of two piece akin GripenB, D, Mir 2000.

The bubbly looking spine can hold sufficient fuel or avionics despite a cofined space. This is called economy without compensating performance. Prime theme of JFT

 

[IndianTiger]

can anybody tell me about the technical reason behind Jf crash. I mean official statement kind of thing.

This news report says twin seater will be ready in 3-4 years and will be a trainer and ground attack plane. China's national aircraft exporter is seeking to expand
its market share by selling more advanced planes to
foreign clients, according to an executive from the
company.
"We have started development of the two-seater FC-1
Fierce Dragon and plan to introduce it to the
international market in three to four years," Ma Zhiping,
general manager of China National Aero-Technology
Import and Export Corp, said at the 50th International
Paris Air Show.
The Paris event, which claims to be the world's oldest
and largest air show, was established in 1909 and is
held every other year at Le Bourget Airport in northern
Paris.
"Many potential buyers have told us they hope we can
produce a two-seater variant of the FC-1 Fierce Dragon.
We are in negotiations with several countries on their
purchases," Ma said. "We hope at least one contract can
be signed this year."
He added the likely deal will involve a considerable
number of FC-1s.
"Around two years ago, I said we had hoped we could
sell 300 FC-1s within five years. Now two years have
passed and the sales record gives me full confidence of
achieving this goal."
Ma's company is the biggest State-owned enterprise
exporting aviation defense products and has a strong
presence in the global military aircraft market. It is run
under the Aviation Industry Corp of China (AVIC), the
country's leading aircraft manufacturer.
The FC-1 Fierce Dragon is a third-generation multi-role
combat aircraft developed by AVIC in coo peration with
the Pakistan Aeronautical Complex, the leading aviation
company in Pakistan.
The aircraft has gained recognition from its Pakistani
users.
"During my trips to many countries, almost everyone I
met would ask me about the aircraft. Many said they
want to join this project," Air Marshal Sohail Gul Khan,
chairman of the Pakistan Aeronautical Complex, told
China Daily.
Compared with the single-seat FC-1, the two-seater will
have better aerodynamic design and more advanced
avionic systems. It can be used as a trainer aircraft and
will outperform the single-seat model in terms of air-to-
surface strikes, Ma said.
Another aircraft highlighted by the Chinese exporter at
the Paris show is the L-15 Falcon, a third-generation
advanced trainer aircraft also developed by AVIC.
Ma said the L-15 Falcon is among the few trainer jets in
the world capable of supersonic flight. It has an
advanced fly-by-wire flight control system and other
state-of-the-art avionic devices. Beside its role as a
trainer aircraft, it has multiple functions such as aerial
combat and air-to-surface strike capability, according to
Ma.
He said a contract to sell six L-15s to an unnamed
African nation was signed at the end of last year.
Chinese aircraft have taken a considerable share of the
trainer-jet market, with about 300 JL-8s — a two-seater
intermedia te jet trainer and light-attack aircraft — being
operated around the world, Ma said.

I don't know why lots of writers say this. Its incorrect

It's NOT incorrect.
Chinese 3rd Gen = world's 4th Gen. This is a fact.
Go search J-20. It will say its a 4th Gen fighter

This is ugly I hope this design is not finalized

until now i was feaaring a twin seater might not be made...and seems quiet a beauty for twin seater if u ask me
