isn't it like navy colour?
IMO it is too light (more white than a PLN-grey) and we know that the Z-10's are alos white in primer !

2 schools of thoughts here:
1. Backup for WZ-10 if the project fell through
2. Lightweight dedicated scout helicopter compliment the WZ-10.
For export market too? SOmething like a JF-17?

JF-17 would've remain a paper-only project if not for Pakistan joined in, then tailored to the latter's requirements.
The thing is, China's arms market is still a "lower-end" of the scale one - essentially, those who can't buy or couldn't buy from the west, but unwilling to buy from the former Soviet-bloc (Russia, primarily), most of these countries are pretty poor or small, their need for rotor-wing assets are predominantly transport or utility type, dedicated scout or attack types don't fit.
Alright, Pakistan is a special case in here, a niche that works out for both Pakistan and China.

Re: 3 advantages of directing helicopter engine exhaust upwards
Projecting the exhaust upwards is mostly a Infrared signature reduction technique one very proven as the RAH66 used it too. it has little barring on the flow as the air flow will mix it up and disperse it too rapidly too make any real issue.
The Acoustical stealth is not the heat exhaust it's the tail rotor. While conventional tail rotors typically have two or four blades, Fenestrons have between eight and 18 blades. These may have variable angular spacing, so that the noise is distributed over different frequencies and thus sounds quieter. The housing allows a higher rotational speed than a conventional rotor, allowing it to have smaller blades. the other main cause is Blade-vortex interaction this is where the rotors rotating though there cycle impact with the air disrupted by the previous rotor blades travel. this effect can be abated via use of main a main rotor with some degree of flex and altered shape the rotor too reduce the effect.3 and 2 are the same, so you lose!! No tofu for you
1, I don't get it. How does engine exhaust produce acoustic signature? And the chopper's main rotor is already loud enough it will drone out any other noise anyway.
Actually, there is one more advantage of that design and it is pretty obvious. If you point the exhaust upward, it obscure/shield the heat source away from being detected on the ground down below by the enemy soldiers. The soldier has to be on a position ABOVE the chopper to be able to target the engine exhaust, by which the exhaust is partially shield by the spinning fan blades anyway and the heat is dispersed quickly by the spinning rotor.

Re: 3 advantages of directing helicopter engine exhaust upwards
Mpleio just posted this Z-19 with millimeter wave radar aka Chinese longbow. This year many new system will be introduced. The modernizing of PLA is surging ahead.This new radar combine with the new EFOGM missile should make it potent sytem
Does this confirmed the position of Z-19 as scout helicopter to complement a much heavier Z-10?
Radar
Despite the original plan, the millimeter wave (MMW) fire-control radar (FCR) is not standard for WZ-10, because the radar was not ready in time. The urgent need forced the early samples of WZ-10 to be evaluated without the planned radar, and it was only later did the radar become available. The MMW FCR for WZ-10 is developed by China Northern Electronic Co. (中国北方电子公司), a subsidiary of Norinco. This MMW FCR is fully solid state and fully digitized, weighing 69.5 kg, less than half of similar former Soviet system. In comparison, both the Russian Arabelet / FH-101 MMW FCR used on Kamov Ka-50N and the Ukrainian Khinzhal MMW FCR used on Mil Mi-28N weight around 150 kg. In contrast to Russian system that uses two antennas, the Chinese MMW FCR adopts western approach of using a single antenna, similar to AN/APG-78 used for AH-64D Apach Longbow. The radar is designated as YH, short for Yu Huo (浴火), meaning bathing in fire. YH MMW FCR is fully integrated with other subsystems of the onboard electronic warfare system, such as radar warning receivers (RWR), laser warning receivers (LWR), electronic support measures (ESM), and electronic countermeasures (ECM), with the entire EW system onboard WZ-10 named after the radar. Final radar deployment configuration has yet to be determined.
