Hello
whats up
Sir why do you think JFT is slightly better than F-7BGI?only because of almost same t/w ratio and the ratio you quoted is also wrong
the specs you are seeing on net of JFT are nt updated since 2007-2008 while the JFT is getting upgrading with the passage of time..
the real t/w ratio of JFT is well over 1..as said in the UK airshow 2010.
the rd-93 with 86kn thrust give 0.95 ratio to JFT bt since in zhuhai airshow we knew that the rd-93 has a maximum thrust of 98kn which give over 1 t/w ratio to JFT.
JFT carry 4 ton payload while F&BGI only 2 ton.
JFT range is 3400km and F7BGI only 2200km
JFT is BVR capable while F-7BGI nt
JFT weapons include anti ship c-80x with a decent range,anti radiation mar 1 from brazil,BVR,WVR(A darter or the latest chineese one),cruise missile ra'ad,h2/4(PGM),
making JFT a true multirole
while f-7BGI carry only WVR and PGM
JFT is much more advance in avionics era..comparing JFT in avionics with F-7BGI is totally BS.
I am not an expert of avionics, but people should read the specifications written in the Airforce Technology I am posting herewith. I have been hearing all along that the F-7BGIs are BVR capable. But, this is the 1st time that I have found reports that supports it. F-BGI is indeed BVR ( Beyond Visual Range) capable. See the specifications below to know that. This plane encompasses many other latest technologies like HUDWAC, as well.
However, there are certain drawbacks of this plane. It has a shorter range and a lighter payload. But, BAF is after a defensive plane only that can finish its mission in short time. Small payloads and short distance also supplement each other. But, this plane is almost as speedy as JF-17 at Mach 1.8.
In case of Bangladesh with a small land, the plane comes back after a short mission is complete and takes new payloads that is taken to enemy positions by a second pilot. This plane is quite compatible with our small landscape and our 4 times larger number of pilots than the number of planes.
I do not think, a BVR-capable F-7BGI would be a dumb plane as some people are trying hard to prove. BVR does not come alone, it must be supported by other avionics. BAF is so secret that we feel we are living in a Communist country. However, we will know about the full specifications of BGIs once these are in Bangladesh.
Since I have edited the specifications in order to shorten it, people are requested to click the link to get the entire page.
J-7 / F-7 - Airforce Technology
An F-7 Length is 14.88m and its Wingspan is 8.32m
The J-7 is a single-engine, lightweight fighter aircraft designed and manufactured by Chengdu Aircraft Corporation (CAC) of China. Its design is based on its predecessor, the MiG-21 aircraft. The export version of J-7 has been designated the F-7.
The J-7 / F-7 has been built principally to meet the requirements of the People's Liberation Army Air Force (PLAAF), and more than 2,400 J-7s are currently operational worldwide.
J-7 variants
In an effort to meet the operational requirements of the defence forces, the CAC has developed 54 variants of the J-7.
Two types of J-7 variants have been built by the company, including a domestic Chinese variant and an export variant. About 28 domestic variants and 26 export variants are in operation worldwide.
The Bangladeshi Air Force purchased 16 F-7MB, 16 F-7BG and eight FT-7B aircraft. These F-7MB aircraft will be replaced with 100 BEYOND VISUAL RANGE-capable F-7BGs by 2010.
Ground attack missions
The J-7 has been designed to perform ground attack missions in all weather conditions. It can climb to higher altitudes with its delta wings at transonic and supersonic speeds. The aircraft also features a small-sized airframe fitted with a powerful engine.It is suitable only for point air defence due to its short-range attacking capability.
HUDWAC avionics
The aircraft is equipped with an efficient avionics system which includes a GEC-Marconi Avionics HUDWAC (head-up display and weapon aiming computer) plus GARMIN global positioning and bombing navigation systems. It is also equipped with a Super Skyranger radar, an FIAR Grifo-7 mkII radar (export) and a Type 226 PD radar.
Cannon armaments
The J-7/F-7 is armed with two 30mm cannons, which can fire munitions at the rate of 60 rounds a minute. The aircraft has five hardpoints, four of which are located under the two wings and one beneath the centreline fuselage section. It can carry a payload of up to 2,000kg. The J-7 is fitted with PL-2, PL-5, PL-7, PL-8, PL-9, Magic R.550 and AIM-9 air-to-air missiles (AAM), unguided bombs weighing 50kg to 500kg, a 55mm rocket pod and a 90mm rocket pod.
"The J-7 fighter aircraft is a copy of the Russian MiG-21."Single turbojet engine
Powered by a single Liyang Wopen-13F/WP-7 turbojet engine the J-7's engine produces 44.1kN of dry thrust, while its afterburner thrust is 65.17kN. The developer of the WP-7 turbojet engine is Shenyang Aero Engine Factory.
Performance
The J-7 can climb at the rate of 155m/s, while the maximum and cruise speeds of the aircraft are 2,120km/h and 1,200km/h respectively. Its combat range is 850km. The ferry range of the J-7is 2,000km and the aircraft can fly to a maximum altitude of 17,800m.
The take-off and landing distances of the aircraft are 800m and 750m respectively. The aircraft weighs around 5,292kg and its maximum take-off weight is 9,100kg.
