Shenlong (spacecraft)

Shenlong (simplified Chinese: 神龙; traditional Chinese: 神龍; pinyin: shén lóng; lit.: 'divine dragon') is a prototype Chinese robotic spaceplane that is similar to the American Boeing X-37.[1] Only a few pictures have appeared since it was revealed in late 2007.[2]

Shenlong Test Platform

The latest academic models shown in 2000, reveal a delta winged spaceplane with a single vertical stabilizer, equipped with three high-expansion engines. Presuming a seating arrangement of two crew members sitting side-by-side in the cockpit, dimensions could be very roughly estimated as a wingspan of 8 m, a length of 12 m and a total mass of 12 tonnes. This is within the payload capability of the Chinese CZ-2E(A) or Type A launch vehicles.

Shenlong Spaceplane

Images of an aerodynamic scaled model, ready to be launched from under the fuselage of a H-6K bomber,[3] were first published in the Chinese media on 11 December 2007. Code named Project 863-706, the Chinese name of this spacecraft was revealed as "Shenlong Spaceplane" (神龙空天飞机). These images, possibly taken in late 2005, show the vehicle's black reentry heat shielding, indicating a reusable design, and its engine assembly.[4] First sub-orbital flight of the Shenlong reportedly took place on 8 January 2011.[5]

It has been proposed that the vehicle is fitted with a Russian-designed D-30K turbofan engine, which would likely not provide enough power to reach low Earth orbit. A larger Shenlong model, however, would be capable of carrying a payload to orbit. Analysts had previously reported on a late 2006 Chinese test flight of what is believed to be a scramjet demonstrator, possibly related to the Shenlong vehicle.[4]

Earlier, images of the High-enthalpy Shock Waves Laboratory wind tunnel of the CAS Key Laboratory of high-temperature gas dynamics (LHD) were published in the Chinese media. Tests with speeds up to Mach 20 were reached around 2001.[6]

As of 2007, the CAS academician Zhuang Fenggan (莊逢甘) said that a first test flight of the spaceplane would be conducted during the "Eleventh Five-Year Plan", meaning from 2006 to 2010.[7]
