isn't it like navy colour?
Does it use an indigenous engine? Would it be the lower-end attack helicopter of choice in the PLA?
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?
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.
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
