China's J31 stealth fighter copied much of the technology of the fifth generation US F-35 fighter jet. Specifications for the J-31 were revealed online.
The J-31 is a mid-weight, twin rudder and twin-engine jet with the typical configuration that is commonly shared by other 5th generation fighters such as Sukhoi T-50. J-31 incorporates certain stealth characters such as forward swept intake ramps with diverterless supersonic inlet (DSI) bumps, trapezoidal wings and a two-piece canopy.
The J-31 appears to be a smaller and more agile aircraft than the Chengdu J-20 that resembles a twin engine F-35C.
The reported maximum engine thrust figure of "88.29 kn" or 9 tons, does conform with statements made by Chinese officials to IHS Jane's at the 2015 Paris Air Show that China was testing a new 9-ton medium thrust turbofan on the Chengdu Aircraft Corporation FC-1/JF-17 fighter. Thought to be an improved version of the WS-13 Taishan turbofan reportedly developed from the Russian Klimov 8.29-ton thrust RD-33 turbofan, it will power versions of the single-engine FC-1 and the twin-engine FC-31. China is working on an improved variant named WS-13A with 100KN of thrust for use on the J-31.
The data posted online describes the FC-31 as "designed for high survivability, low radar detectability, low IR (infrared) signature, and excellent capabilities for electronic counter measures".
Avic said the fifth-generation fighter jet, which has a 1,200 km (750-mile) combat range and a top speed of 2,205 kph (1,370 mph).
The J31 has a maximum payload capacity of 8 metric tons.
Pakistan Air Force is looking to buy 30 to 40 J-31 aircraft.

Police in Malaysia's Sabah state have received a report claiming that an aircraft wreckage with the Malaysian flag painted on it was found on a southern Philippines island.
The report was made by a man who said the wreckage with human remains inside was spotted by his nephew, from the southern Philippine island of Tawi Tawi, at Ubian Island in southern Phillippines several days ago.
State Commissioner Jalaluddin Abdul Rahman said the man made the report at the Sandakan police station on Saturday.
In the report the man, an audio visual technician in his 40s, said his nephew and a few others were hunting for birds when they spotted the wreckage on the island.
They managed to get near the wreckage where they found human bones. They also found skeletal remains in the pilot's chair with the seat belt fastened.
Before leaving the area, they took a flag they found in the wreckage.
The man said he informed police as the wreckage could be that of an airplane that disappeared last year.
Malaysia Airlines flight MH370 disappeared in March last year en route from Kuala Lumpur to Beijing with 239 passengers and crew on board, most of them China nationals.
The incident triggered one of the largest search for an aircraft focusing in the Southern Indian Ocean.
Last month, French authorities confirmed a piece of wing found on the shore of Reunion Island in the Indian Ocean has been identified as part of the MH370 wreckage.
The flaperon was found on the shore of the French-governed island on July 29 and Malaysian authorities have said paint colour and maintenance-record matches proved it came from the missing Boeing 777 aircraft.

A former French airline CEO Marc Dugain claims that the US may have shot down Malaysian Airlines flight MH370 and then covered it up, adding to a rash of conflicting theories about the missing plane.
In a six-page article published by French weekly Paris Match, Dugain claims that the Boeing 777 may have got into trouble and as it was approaching the US military base on the British territory of Diego Garcia in the Indian Ocean, it was shot down. US forces may have feared the plane was attempting a 9/11 style attack on the base, Dugain said.
“It’s an extremely powerful military base. It’s surprising that the Americans have lost all trace of this aircraft. Without getting into conspiracy theories, it is a possibility that the Americans stopped this plane,” Dugain said, English-language website The Local reported Friday.
Dugain said there were witness in the Maldives, the nearest islands to Diego Garcia about 500 kilometers to the north, who claim to have seen a “huge plane flying at a really low altitude” with Malaysian Airlines colors flying toward Diego Garcia.
In August, the UK Daily Mirror reported that the MH370 was heading for the tiny Indian Ocean atoll of Diego Garcia, but the US Embassy in Kuala Lumpur denied this. A spokesperson for the US Embassy in Malaysia told the local Star newspaper at that time that there was “no indication that MH370 flew anywhere near the Maldives or Diego Garcia.”
He added: “MH370 did not land in Diego Garcia.”
Dugain writes that the aircraft, which disappeared on March 8 with 239 people on board, while on a scheduled flight from Kuala Lumpur to Beijing, could have been hijacked remotely and then steered toward Diego Garcia.
Another explanation, he says, is that an onboard fire forced the crew to turn off all electronic devises without damaging the plane’s exterior, allowing it to continue on autopilot with everybody on board asphyxiated.
The testimonies of witnesses in the Maldives have been suppressed, Dugain claims, adding he was approached by a British intelligence officer, who warned him he would be taking “risks” by trying to find out what really happened to the MH370. As the British own the island, it would figure they would cover up any incident, Dugain said.
The US has consistently denied it has had any knowledge of the fate of the airliner, but Dugain doubts the US, which is “equipped with the best technology in the world” could have completely lost track of “a 63-meter-long object.”
Sir Tim Clark, CEO of Emirates Airlines, the world’s largest, said in October that he thought information on what happened to the doomed airliner was being withheld by some people and that even with all its electronic communications systems turned off the plane would still be traceable by powerful military radar.
There have been a host of theories about what could have happened to the missing airliner, some them seemingly more the stuff of thrillers than air crash investigators.
British journalist and author Nigel Cawthorne said that it may have been shot down by military exercisesbeing conducted by Thailand, Japan, Indonesia, the US and personnel from China in the South China Sea.
Even more far-fetched is that MH370 could have been flown north in the shadow of another plane and would have avoided detection on radar before branching off and landing at an airfield in north east China, Kyrgyzstan or Turkmenistan.
A third claims there could have been a botched hijack attempt. Analysis of radar data shows the plane began to fly erratically and climbed to 45,000 feet before dropping to a very low altitude.
The pilots could have flown like this to disorientate the hijackers or the hijackers themselves could have flown the plane up to this altitude to kill the passengers by starving them of oxygen by depressurizing the cabin, while they had access to another oxygen supply. Under this theory the attempts fails and the hijackers accidentally kill themselves.
In October, the investigation was focused entirely around an underwater search. As of December 17, 11,000 square km of the seafloor had been searched. The search of the southwest Indian Ocean is being conducted by three vessels and is expected to be completed by May 2015.

A piece of aircraft wreckage discovered on a remote island in the Indian Ocean has raised hopes that it may be from the missing Malaysia Airlines Flight 370. But the possibility was not greeted with joy by all.
Sarah Bajc's boyfriend, Philip Wood, was on the Boeing 777 before it disappeared on a flight from Kuala Lumpur, Malaysia, to Beijing with 239 people on board on March 8, 2014.
"My initial reaction was I wasn't sure whether to believe it because there have been so many false alarms," Bajc said in a statement to NBC News Wednesday.
"If it is from the plane than any hope that I might have had that this plane landed safely somewhere is harder to believe," she said. "My thread of hope goes away."
The wreckage was found Wednesday on the coastline of rugged Reunion Island, a French territory east of Madagascar off the southern tip of Africa. The wreckage has not been confirmed to have been a part of Flight 370.
Sources told NBC News that Boeing investigators have looked at photos of the piece of debris and believe it appears to have come from a Boeing 777. There is only one 777 missing in the world right now — Flight 370, also called MH370.
Bajc was preparing to move from Beijing to live with Wood, a 50-year-old Texas native and IBM Malaysia employee, in Kuala Lumpur at the time of the tragedy.
Bajc said that if the wreckage is determined to be from Flight 370, the confirmation would bring closure and perhaps some insight into why the passenger plane went down. She does not believe Malaysia has been tough enough in its response.
"I am still very angry at the country of Malaysia for their lack of efforts to hold anyone responsible for this," Bajc said. "They have failed the world."
Search crews from around the world have scoured the vast region for any sign of the missing plane, but no debris confirmed to have come from the aircraft has ever been found.
