Another light armed reconnaissance helicopter, the WZ-19, or Black Tornado, also made its maiden public appearance on Tuesday.
It is also developed and manufactured by the Aviation Industry Corp of China and will be used primarily for reconnaissance and supporting ground forces, experts said.
"The WZ-10 and WZ-19 can supplement each other in combat with the WZ-10 being an advanced attack helicopter and the WZ-19 playing a supporting role," Wu Peixin, an editor at Aerospace Knowledge, said.
"They represent the advanced specialized military helicopters in the world, and more important, their entry into service enables China to develop ground aviation forces without being disrupted or contained by anyone else."
Homegrown jets
The C919 also broke new ground with five confirmed and five optional orders from GE Capital Aviation Service.
The US aircraft leasing company ordered 10 C919 aircraft in 2010.
"Increasing orders show that both domestic and foreign consumers have given the C919 their endorsement,'' said He Dongfeng, general manager of the Commercial Aircraft Corp of China.
The aircraft will be using the world's leading technology and is competitive, he added.
