CZ-6A (Tiankun 2, Pujiang 2)
CZ-6A (Yaogan 40)
The launch vehicle was developed by China Aerospace Science and Technology Corporation and the China Academy of Launch Vehicle Technology.
CZ-6 features a 3.35 m diameter first stage fueled with LOX and Kerosene and powered by one YF-100 engine. Originally the vehicle was to be based on the 2.25 m small strap on of the CZ-5 family, but was changed to the 3.35 m diameter of the bigger booster and the CZ-7 family, although shorter and using only one instead of two engines.
The second stage has the smaller 2.25 m diameter and uses the same fuels with one YF-115 engine.
A restartable third stage reportedly uses the storable combination of Kerosene and Hydrogen peroxide. With four YF-85 engines it provides final orbit trim and can manoeuvre to different orbits to deploy multiple satellites.
CZ-6 can deliver 1500 kg into a low earth orbit or 1080 kg into a 700 km sun synchronous orbit.
Taiyuan is used as a launch site for the maiden launch in 2015, although later the new Wenchang cosmodrome will also be used.
An improved CZ-6A (Chang Zheng-6A) is planned to be introduced during the 13th Five Year Plan (2016-2020). It features 4 strap-on boosters of 1 m diameter, a lengthened stage one, a new stage two with the same diameter as stage one. It is planned to put up to 4000 kg into a sun-synchronous orbit.
