Bro. Thats ditto apache. First blackhawk and now apache. It doesn’t look good on PLA. They could had chose any external design but ended up copying US helicopter design.
Form follows function. Z20 was designed after the PLA’s two decades of existence with S70 Blackhawks. Blackhawk looks the way it does as the U.S. Army laid out requirements for crash absorbing wheeled gear as opposed to the H1’s struts or the retractable gear on a civilian helicopter.
In Attack Helicopters again form follows function. The basic configuration is the same across any number of different aircraft. Many old coldwar aircraft recognition books used the AH64 profile to stand in for the then rumored Mi28. The T929 mockups have the same configuration. Tiger helicopter and Rooivalk also have the same configuration. The KA50 family doesn’t follow this sure but it wasn’t supposed to be a conventional attack helicopter. The Soviets have the Mi28 for that. It was supposed to be a sort of scout attack helicopter.
the Mi24 doesn’t either but that’s because the Soviets were trying to make a helicopter that both transported assault troops and was a gunship. The result is less than great at either role.
The final one that breaks the mold was the one that set the mold the AH1 Cobra family,
But that breaks the mold in that it was so early it was powered by a single engine originally and armed with a grenade launcher and Minigun in the nose turret for mostly rockets. It has skids because those transitioned from its parent the UH1. Later it gained a second engine and moved to a 20mm Gatling gun for the super cobra but it’s always been a mixed Scout attack helicopter.
Now you could break out some experimental models but they are all just that experimental or failed. The form that sticks the most is known. Two tandem seats, fixed reversed tricycle gear with crash absorbers, conventional rotor with high mounted tail twin engine, belly gun, stub wings. It looks like Apache because for an attack helicopter that’s the most successful configuration.
I suppose that India, South Korea and Turkey could have chosen any external design but ended up copying the US' F-22 and F-35 designs instead?
They also consulted with LM at least on the KF21.
