The black smoke thing only occurs frequently on Russian imported rd-33 engine which happens to be install on the first prototype of FC-31. And thick black smoke don't always occur as only when pump increase fuel. We all can see JF-17 during most of the flight do not produce thick smoke and small amount of trail light smoke.Source: View attachment 554220
Chinese new engine developed successfully! What models will be equipped in the future? CCTV reveals important information.
18-04-2019
Recently, several online photos show that China has achieved success in the development of new aero engines. In the 22nd "Sichuan Youth May Fourth Medal" to be commended, the picture of the development team of China Aerospace Turbofan Engine was announced. In addition to the team's concern, the engine behind it is more interesting. The engine was covered with a thick mosaic, and although it was coded, the outline could still be distinguished. From the outline point of view, the engine nozzle is not large, but it is suspected to be jagged. If it is jagged, it may be a vector aero engine or a stealth engine specially designed for stealth fighters.
In terms of size, the film is speculated as a medium-thrust aero engine, not a large-thrust engine. Some analysts believe that this is a turbofan-15 large thrust aero engine, but more it is considered a medium-thrust turbofan-19 aero engine. Because it is a turbofan-15, its size will be larger, for which more analysis is considered to be a turbofan-19 aero engine. The engine had previously been rumored that it entered the two-machine special project in 2016 and became a national key model, which means that the Russian development of the engine has been successful. In fact, the turbofan-19 is a medium-thrust engine. It is not the same as the turbofan-10 series and the turbofan-15. It is just the same level as the turbofan-13 series. The thrust is less than 10 tons. It is suitable for light fighters or medium-duty doubles. Use with fighters, such as the Dragon Fighter, the medium-sized dual-engine FC-31 "The Eagle Stealth Fighter" or some trainers.
What models will be equipped in the future?
What kind of aircraft will be equipped in the future? If it is a turbofan-medium thrust engine, it will gradually replace the turbofan-13 series engine in the future. Its positioning is similar to that of the Russian Air Force's RD-93 aircraft engine and the US Army F-414 aircraft. The engine, one equipped with the MiG-29, and one equipped with the F/A-18 "Super Hornet". The RD-93 aero engine is now being mass-produced on the FC-1/JF-17 "Dragon Fighter" and becomes the main power unit. Although China's turbofan-13 engine has been successfully developed for many years, it is equipped with very few aircraft. Although the parameters are more advantageous than the RD-93, there is actually a big gap.
At the Zhuhai Air Show in 2014, the FC-31 "Suiying" stealth fighters appeared at the Zhuhai Air Show, which left a deep impression on the audience. At the same time, the engine smoky during the flight show disappointed the audience. Because the engine of the FC-31 "Suiying" stealth fighter was suspected to be a turbofan-13 model, the lack of power caused the occurrence of black smoke problems. If the turbofan-19 was successfully developed, then the future FC-31 "鹘鹰" stealth The fighter can solve the power problem. Judging from the video released by CCTV, the video has a large number of images of the FC-31 "Suiying" stealth fighter, and it is likely to become its core power in the future.

Judging from the current data, the maximum take-off weight of the FC-31 "Eagle" stealth fighter is below 28 tons, which is only equivalent to the US F-35 "Lightning Joint Attack Aircraft", but it is more than the Russian MiG-29 "Pivot Point". "The fighter plane is much higher than the US Army F-18 nickname "Hornet". Therefore, once the turbofan-19 is successfully developed, the prospect of the future FC-31 "Xiaoying" stealth fighter will be more clear, and it is impossible to rule out the possibility of getting on the ship. From its size and take-off weight, it is entirely possible to become China. The next generation of aircraft carrier carrier aircraft, specifically how we are not good, let us look forward to this!

According to another source. WS-13 is the first modern turbofan of China approved for mass production. It is quite a successful engine project for China aviation. It also the catalyst for quick development of more advance WS-19 turbofan.
