I was going to post on @Kshatriya87 's thread on the CH5. Considering the multiple efforts to develop a MALE UAV for the different arms of the PLA, I decided it would be better to create a thread where all Chinese MALE drones can be discussed:
To kick things off, here's a translation of Henri K's article on the CH5's first flight on eastpendulum.com
Military drone CH-5 takes off

The duel between the two largest manufacturers of military drone in China continues to rage - after the first flight in February of MALE UAV Wing Loong II designed by the aircraft manufacturer AVIC, it was the turn of the CH-5 the group of Chinese aerospace company CASC which made its inaugural flight this week at an airfield in northern China.
The 3.3 ton drone was towed on site around 1400 hours on Friday, 14 July, protected by a military camouflage tarpaulin and another waterproof in blue color.
After about two hours of preparation, notably to check the various on-board and on-ground systems, and also to refuel the CH-5's piston engine, the aircraft took off and landed A 20 minute flight, all fully automated.

The CH-5 program actually did a first flight two years ago, in August 2015, but it was a prototype that was completely revised thereafter.
It is the same model presented last year at the Zhuhai Airshow 2016 which took off this week in an aerodrome whose name was not revealed.
Compared to its prototype, the CH-5 is no longer the same aircraft. While it preserved the V-tail and the same reciprocating piston engine, the aerodynamics were completely modified. The front tip is in "negative dihedral" now, the middle wings have replaced the low wings and the vertical stabilizing keel has been removed.
Not to mention the fuselage that has been completely redesigned to take into account, in a way, passive radar stealth.

As for the performance of the CH-5, the communications made by its designer CAAA, subsidiary of the group CASC, are quite confusing. Indeed, if its chief engineer SHI Wen spoke more than 10,000 km and 60 hours autonomous flight to Xinhua Agency reporters after the first flight of this new CH-5, the figures given to Zhuhai Airshow 2016 are only 6,500 km and 40 hours of flight, when the drone was still presented in the form of a scale model.
In comparison, the Wing Loong II of a MTOW of 4,200 kg can only be kept in flight for 20 hours by being armed, for a size comparable to that. It is therefore hard to imagine that for a MTOW 25% weaker, we have three times the autonomy and twice as many external frequencies.
The most likely explanation is that the figures released this week are only targeted characteristics, while the current UAV is performing more modestly.

Wing Loong II and CH-5 compete in the external market, especially in the large market in the Middle East where the two families of drones Wing Loong and Cai Hong (CH-x) Already conquered a large number of countries, such as Saudi Arabia, the United Arab Emirates, Iraq, Egypt, Jordan ... etc, the design philosophy behind these two products remains very different.
When the 611 Chengdu Institute favors both the survivability of its Wing Loong II with an operational ceiling and a higher cruising speed, and the variety of missions with a wide range of ammunition, the CAAA aims, for its part, Easy and inexpensive operation, thus the cost of the overall life cycle much lower for future CH-5 customers.
For example, SHI Wen revealed that the cost of producing a CH-5 is only 25% of the US MQ-9 drone , and one of the tricks to get to this seems interesting - unlike the RQ-9 which has been designed to last as long as the cell, but which considerably increases the cost of design and production, CH-5 only lasts 33% of the total life of the drone but its cost Is also divided by three. The CBW has been adapted and reinforced to allow for more frequent wing change. This choice reduces the cost of production and the risk of having to completely change the "all-life" wing after intense use, but does not change the cost of the customer use cycle.
The full-scale model of CH-5, presented at the last Zhuhai Airshow 2016.
Armament level, the CH-5 has six points of loading able to charge two different types of missiles today - the Air-Sol AR-1 missile of 45 kg and a range of 10 km already widely used in Iraq , And a smaller one, the AR-2 , which is a new missile model weighing less than half - which allows different types of targets to be addressed with greater flexibility and efficiency.
The CAAA is also planning to propose its new MALE drone for civilian missions such as maritime surveillance and geological surveys. For this purpose, several internal payloads have been designed, ranging from the optronic ball to the embedded SAR radar, via the hyper-spectral camera for example.
Finally, although the authorities did not want to reveal the exact location where the CH-5 made its maiden flight, but based on one of the photos showing the drone control screen, The image of a runway, it is believed to be Pingquan Airfield, a level 2 permanent reserve airport of the Chinese Army with a 2,400-meter runway. The facility is located about 223 km northeast of the city of Beijing, where the CAAA site is located.
