China have plenty of domestic options..I've been wondering what engines does large Chinese drones/UCAV use? I don't think China has any turbofan engines within the expected thrust range for large drones(~5tf for large drones such as CH-7/WZ-7/GJ-11/GJ-21)
They will eventually replace it with a turbofan soon I assume? Turbojets are notoriously inefficient at subsonic speeds. IMO it seems weird that they choose an old turbojet for a HALE drone which I presumed to require highly efficient turbofan engines for longer range. Or was there a specific reason that WZ-7 might require a turbojet? Maybe extreme high alt performance?WZ-7 Soaring dragon powered by WP-13 turbojet from AECC Guizhou Liyang. this engine is borrowed from J-7.. WP-13 turbojet have many variants.
honestly, there is not much information available about these smaller engines. but i have heard, WP-13 has already been replaced with turbofan engine but again, we don't have any authentic information.. even if they didn't replace but it will eventually replace with turbofan.They will eventually replace it with a turbofan soon I assume?

Some rumours going on about a certain UAV being excessively expensive
A certain province’s private company is really ruthless. Don’t be fooled by the airshows and promotional material boasting “excellent quality at a low price” — when it comes down to it, the price they’re quoting domestic users for an armed reconnaissance UAV is approaching that of a J-10 fighter. Sure, it’s high-end, but it’s not worth paying several times the price of a Wing Loong or a CH drone…
User: "Where did you get the nerve to quote that price? Do you seriously think I’m rich enough to treat a J-10 like a disposable item and not feel a thing?"
Because they previously clung to a powerful backer and landed a sizable foreign trade deal, they had a good run and aren’t too anxious now — so when they later moved into the domestic market, they got cocky.
They believe their product is excellent, so why shouldn’t they charge more? That’s why it’s been hard to sell.

Some comments debate if it's TB-001, some other comments are also saying they have heard TB-001 is expensive.
