Re: JF-17/FC-1 Fighter Aircraft thread 2009

In order to do a steep climb like that, you need to have a higher TWR than 1:1 at that moment. I think if it was possible for JF-17 to have more than 1:1 TWR at anytime, in any config (e.g. low fuel) then they would have advertised the crap out of it as "higher than 1:1 TWR!". Given that the aircraft is mainly geared for export, I doubt they would hide any specs that make it look good.

The JF-17 has a TWR of 0.99 with full fuel.So surely, if its half filled with fuel, it will have a much higher TWR. However, in order to go vertically up, you need (TWR-drag)>1.

Strangely enough even though JF-17 is an export fighter, not everything about it is known. Both official sources (CAC or PAC) do not have a complete specs and the ones havent been updated for ages. Maybe because fighter jet customers will directly contact the company and unlikely to a website to read a brochure or watch a promotional video.

JF-17 has yet to perform tricks in an Air Show so its yet to be seen what it can (or cannot) do. Lets hope it appears in the next Zhuhai Air Show and demonstrates whats up its sleeves.


Btw, any latest news of the WS-13 engine?

For a takeoff from the surface of the earth using thrust and no aerodynamic lift, the thrust-to-weight ratio for the whole vehicle has to be more than one. In general, the thrust-to-weight ratio is numerically equal to the g-force that the vehicle can generate.[6] Provided the vehicle's g-force exceeds local gravity (expressed as a multiple of g0) then takeoff can occur.

twin engine FC-1? rumor that twin engine FC-1 may be under develop.
the concept is very similiar to Mirage-4000,twin engine version of mirage 2000.

Where did you hear that rumor and how reliable is it?

I think that's actually only a fan-boy-rumour based on a CG posted about a year ago looking like a mini-JSF.

I even can't think of yet another completly new type besides the J-10A and corrent B-development work, the FC-1 itself and work on the XXJ ... and not more or less a twin-engined FC-1 would a new aircraft.

Just found this from a Chinese Forum:
军事啦军事啦，本期HKZS暴料，TG自己要装备FC啦，外挂从3吨提高到5到6吨，有双座型，加强对地攻击能力
MBD，说错啦，是航空世界，不是航空知识，航空世界09年06期（MBD很恶心的从10块涨到12块了），第24—25页，“枭龙”的发展与未来，访中航技航空产品发展部部长李培。P25后续改进计划，大幅度提高航电设备，推力增加，加装矢量喷管，外挂能力从3.6吨提高到5~6吨，机翼结构和起落架加强（这就不难理解为什么要有新的静力实验机了），增加空中加油能力，发展双座型。

It says, a Chinese magezine called <Aviation World> claims PLAAF will purchase JF-17, upgraded version(with stronger airframe, IFR probe, TVC nozzles, payload gonna be increased from 3.6 ton to 5~6 ton) and two-seats version is also on the way...

Actually Deino, I have also read rumors of some changes coming from the pakistani side and those people aren't fanboys.

I am trying to think of an aircraft say F-XX, with one version a single engine and a second version a twin-engine. Not like J-7 and the J-8 - these are two different types of planes. If something BASED on the FC-1 comes out with two engines, it sure will not be an FC-1, it will be called by a different name, maybe JF-XY where Y ≠ 7!

If that is the case, WS-13 is really on the card. And TVC is logical since FC-1 doesn't have canard and that will handicapped its ability in high speed tight turn.

TVC add another extra 125lbs. weight,this will require much more powerful engine.
