J-20 Mighty Dragon "2002" first flight
J20
Extended version follows:
J20
[Note: Thank you to Frank Lau for the video links.]
----------
J-20 Mighty Dragon has three times the combat radius of the F-22 Raptor
I view the J-20 Mighty Dragon as a large F-22. It has greater range and a similar payload. Two side-bays for short-range air-to-air missiles and a main weapon bay to carry medium-range air-to-air missiles.
J-20 combat range: 1,243 miles (see Chengdu J-20 - Wikipedia, the free encyclopedia)
F-22 combat range: 471 miles (see Lockheed Martin F-22 Raptor - Wikipedia, the free encyclopedia)
----------
The cube root of 3
In an earlier post, I made the claim that the J-20 Mighty Dragon has a far greater combat radius (e.g. 1,243 miles) than the F-22 (e.g. 471 miles).
Obviously, it is indisputable the J-20 has significantly longer range than the F-22. Your eyes can easily note the larger physical size of the J-20 in a photographic comparison (with the pictures normalized to match the sizes of the pilots' helmets and airplane wheels).
Anyway, we're moving onward to a mathematical analysis. For a J-20 to have three times the range of a F-22, it needs to carry three times the fuel. Volume is determined by three dimensions (e.g. length, width, and height).
To carry three times the fuel of a F-22, the J-20 must have a fuel tank that is three times larger. The cube root of three will indicate how much larger the J-20 fuel tank must be in physical dimensions.
The cube root of 3 = 1.44
Thus, if the J-20 fuel tank is 1.44 times longer, 1.44 times wider, and 1.44 times taller than the F-22 then the J-20 has three times the fuel load of the F-22.
Anyway, I don't have the schematics for the J-20 and F-22. However, it is entirely plausible that the J-20 fuel tank is 1.44 times larger than the F-22 in all three dimensions. Therefore, it is credible the J-20 has three times the combat radius of the F-22. The US Air Force screwed up in building an air superiority fighter with such a short range.
China can easily bomb (with ballistic, cruise, or MLRS missiles) any potential airfields that may serve as a base of operations for the F-22. Without a base to resupply fuel and ammunition, the F-22 is out of action in the Chinese theater of operation.
[Note: I am aware the J-20 will weigh a little more than the F-22 and it will have to carry a little more than three times the fuel load. However, this is offset by more lift from the canards and the calculations are meant to be approximate to illustrate a point.]
Seriously ??? to travel 3 times longer, it needs to have 3 times larger fuel tanks? Which planet did you come from?
the terms engine efficiency, drag, sustain military thrust consumption, operational load capacity mean nothing to you?

Heck that is confusing..
By that logic .. an A-380 should outrange the B-777LR by how much???

Utter nonsense. This is what happens when we have someone with absolutely no relevant experience going by 'looks' alone and starts making a fool out of himself.J-20 Mighty Dragon has three times the combat radius of the F-22 Raptor

Wow...Anyway, I don't have the schematics for the J-20 and F-22. However, it is entirely plausible that the J-20 fuel tank is 1.44 times larger than the F-22 in all three dimensions. Therefore, it is credible the J-20 has three times the combat radius of the F-22. The US Air Force screwed up in building an air superiority fighter with such a short range.
a. This mission need statement (MNS) provides requirements for a theater missile defense (TMD) capability.
Fine......How about all of China's is within the B-2's combat radius. Remember, during the Yugoslavia air campaign, B-2s flew from CONUS to Yugoslavia and back without landing.China can easily bomb (with ballistic, cruise, or MLRS missiles) any potential airfields that may serve as a base of operations for the F-22. Without a base to resupply fuel and ammunition, the F-22 is out of action in the Chinese theater of operation.
Now that is more 'Chinese physics' in play. If this is true, then why are airliners, aircrafts whose weight lifting capability is paramount, do not have canards? If anything, these airlifters should be festooned with various sized wings and winglets EVERYWHERE.[Note: I am aware the J-20 will weigh a little more than the F-22 and it will have to carry a little more than three times the fuel load. However, this is offset by more lift from the canards and the calculations are meant to be approximate to illustrate a point.]
Any real data to go with that...??? Or is this more 'Chinese physics'?Regarding drag, the J-20 is a more aerodynamic plane than the F-22. The F-22 has two large gaps between the engine airducts and the fuselage. Air will flow into the gaps and create drag for the F-22. The J-20 is a later and more modern design. There is no drag-inducing gap. Instead, the J-20 airduct has been seamlessly integrated into the fuselage. Therefore, the superior design and less drag favor the J-20.
A longer combat radius does not automatically equal to superiority. The F-15 have a greater combat radius than the F-22 but guess who is going to die first when they meet each other?1. J-20 Mighty Dragon 1,243-mile combat radius is indisputably LONGER than F-22 471-mile combat radius. Look up the word "longer" in the dictionary.
China have no experience in such attacks, let alone 'easily'.2. The F-22's short 471-mile combat radius is a problem, because it means that it must fly from a base in Japan (or Korea). However, China's SRBM, IRBM, and cruise missiles can easily destroy all major air bases on Japan.
When an F-22 is 'less stealthy' it is within someone's radar detection range. Get it? But since you have demonstrated gross ignorance and misunderstanding of 'stealth' to start, I would not be surprised if you do not understand.3. Using a drop tank on the F-22 would render it less stealthy. By the way genius, how is the F-22 supposed to fly from Shanghai back to Alaska? Is there a drop tank store in mid-air on the way back?
This indicate you do not understand how external fuel works at all.By the way, there is an additional problem. Even if a F-22 flying out of Alaska (or Guam) was able to somehow reach the Chinese coast with drop tanks, it would have little to no loiter time. Basically, the F-22 is useless and cannot engage in aerial combat. It's out of fuel. If it doesn't leave immediately, it will have to crash land. This is a one-way trip.
That is funny considering no one have as much experience as we do. So now you are telling everyone that the USAF never -- NEVER -- considered that possibility. I hope the PLAAF thinks like you do.4. The use of gigantic air-refueling tankers is out of the question. They'll be shot down by Chinese surface-to-air missiles, J-10 air-to-air missiles, or a stealthy J-20 (when inducted).
Look up effective radar horizon and see how useful those radars can be. Not much.5. The B-2 is subsonic. It is a slow moving and lumbering aircraft. One of the designers for the B-2's engine has already spilled many of its secrets to China. The B-2 should be detectable with Low-Band radar (see Russian / PLA Low Band Surveillance Radar Systems (Counter Low Observable Technology Radars)). Chinese interceptor aircraft can be vectored in to intercept the subsonic B-2 sitting duck.
Got any hard data?6. Are you a moron? The air gap between the airduct and fuselage on the F-22 leads to a roughly 45-degree angled wall in the back. Are you telling me you don't understand that there is significant drag when high-velocity air (especially when the F-22 is flying supersonic during supercruise) collides with a solid angled wall? You make it sound as if you've never seen a photograph of the rear of the F-22 airduct-fuselage gap.
Meters lengths freqs systems are ground based, therefore their EFFECTIVE detection range are line-of-sight limited from the ground, not from being airborne.1. Low-Band radar can provide information on the general location of a stealth plane. The Low-Band radar can guide an interceptor to the general location of an enemy stealth plane. Using an AESA-equipped radar, an interceptor should be able to detect an enemy stealth fighter within 20 miles.
That is not the issue. Your argument is that the J-20 is 'more aerodynamics' than the F-22 based solely upon the diverter assembly.2. Try reading the definition of "drag." It perfectly fits supersonic air slamming into the rear wall of the F-22 airduct-fuselage gap. Jesus, I can't believe you're questioning the basic definition of "air resistance." Are you for real?
Drag (physics) - Wikipedia, the free encyclopedia
"In fluid dynamics, drag (sometimes called air resistance or fluid resistance) refers to forces which act on a solid object in the direction of the relative fluid flow velocity.[1][2][3][4] Unlike other resistive forces such as dry friction, which is nearly independent of velocity, drag forces depend on velocity.[5]"
