Tang Changhong has held the position since 2007 and had previously also been the chief designer of the JH-7A strike aircraft. The design and manufacture of the Y-20 involved over a 1000 companies and research institutes.
According to Tang Changhong, the Y-20 may enter service within 5 years provided testing continue to proceed as planned. The aircraft was tested successfully on January 26 and so far test flights have gone well.
Preliminary specifications of the Y-20 from the Xi'an Aircraft Industrial Corporation, which is part of Aviation Industry Corporation of China, are:
- a length of 47 m
- a wingspan of 45 m
- a height of 15 m
The Y-20 will have the option of using several different types of engines. Tang Changhong confirmed that China is developing its own engines for the Y-20, which will be tested during test flights.
The Chinese engines will offer improved thrust-to-weight ratio and fuel efficiency. The four D-30KP-2 engines currently installed produce 12500 kgf / 27560 lbf / 122.6 kN of thrust each.
Once the domestic engines are installed, the Y-20 will increase its takeoff weight and be able to carry a payload of up to 66 tons. Once the Y-20 has entered service, it will continue to be upgraded and improved.
