Chinese UAV & UCAV development

A single, large, modern turboprop would be optimal, from endurance standpoint. Though it may lack in cruise speed and altitude, compared to a turbofan/turbojet. IF those two are priorities, then it's to be expected a turboprop was not chosen.

A single, large, modern turbofan would be the following engine of choice. But for some reason, the maker chose to go with two smaller engines. Possibly because those were readily and cheaply available, and other solutions would have required lengthy and pricy development. The fact the engines are fairly long and not wide also points out to the possibility those are turbojets and not turbofans. Which would again not be as good as having two turbofans, fuel consumption wise.

CH-817 Micro UCAV:
- Weight: 850g
- Max speed: 18m/s
- Endurance: 15min
- Co-axial rotor, VTOL capability
- Intended targets are armed individuals (i.e. soldiers, terrorists)
- Built-in obstacle avoidance
- Can be deployed by individual soldiers or larger UAVs
- Capable of cooperative swarm tactics. A CH-817 swarm can be deployed by a larger UAV. A swarm can then conduct wide area surveillance and precision strikes against individual targets.

But if it will be be more expensive then a Close air support Aircraft like Super Tucano is better almost same payload and speed

Loss of 10 Super Tucano would mean services of 20 airmen are lost, unless they are rescured and get back to active service in no time. (Suggestive 10 losses taken as reference to Saudi's UAV losses in the Yemen war).

There is no such problem with UAV since they are expendible hardware. Hardware are easily replaced, air crew needs many years of training.
