The Changhe Aircraft WZ-10 attack helicopter is based on a Russian design commissioned by the Chinese, Kamov's chief design engineer says.
In 1995, Kamov developed a preliminary design in the 6t weight class under a contract with the Chinese government, says Sergey Mikheev, Kamov's chief design engineer, speaking at the Heli-Expo trade show in Las Vegas, Nevada.
"Due to understandable reasons, this information was kept secret," he says.
The Project 941 design was not based on any Soviet-era attack helicopter project and was strictly designed for China's unique requirements, Mikheev says. "They gave us the desired weight, we discussed preliminary performance parameters, then we signed a contract and we fulfilled the contract," he says.
After Kamov completed the design, the Russian design bureau verified the design via testing. Kamov then delivered the design to China and the Project 941 concept was accepted by that country's government for further development, he says. Kamov did not participate in any further developmental work on the WZ-10, he insists.
Thereafter, to the country's credit, Mikheev says, the Chinese handled the rest of the developmental work. That includes the developmental prototypes and the operational aircraft that is currently in production for the Chinese military.
"So I wish success to the helicopter," Mikheev says.
Mikheev would not comment on the WZ-10's performance. "That is a question for the Chinese," he says. "I know what I have done."
