Long March 3

The Long March 3 (Chinese: 长征三号火箭), also known as the Changzheng 3, CZ-3 and LM-3, was a Chinese orbital carrier rocket. It was launched from Launch Area 3 at the Xichang Satellite Launch Center. It was a 3-stage rocket, and was mostly used to place DFH-2-class communications satellites into geosynchronous transfer orbits. It was complemented and later replaced by the more powerful Long March 3A, which has an improved third stage.

Launch failures

Dong Fang Hong 2 launch failure

On January 29, 1984, a LM-3 rocket failed during launch. The third stage failed 4 s after restart for GTO insertion of the satellite, due to incorrect mixture ratio in the engine gas generator, which caused high temperatures and burned out the turbine casing. However, many planned tests on the experimental communications spacecraft were still carried out in the resulting elliptical orbit.

ChinaSat 4 launch failure

On December 28, 1991, a LM-3 rocket failed during launch. The third-stage engine suffered a loss of turbine speed and combustion pressure 58 s after re-igniting for the second burn for GTO insertion and shut down completely 135 s after re-ignition. Loss of pressure in the high-pressure helium supply used for engine control had reduced the propellant flow.

Long March

The Long March (October 1934 – October 1935) was a military retreat undertaken by the Red Army of the Communist Party of China, the forerunner of the People's Liberation Army, to evade the pursuit of the Kuomintang (KMT or Chinese Nationalist Party) army. There was not one Long March, but a series of marches, as various Communist armies in the south escaped to the north and west. The best known is the march from Jiangxi province which began in October 1934. The First Front Army of the Chinese Soviet Republic, led by an inexperienced military commission, was on the brink of annihilation by Generalissimo Chiang Kai-shek's troops in their stronghold in Jiangxi province. The Communists, under the eventual command of Mao Zedong and Zhou Enlai, escaped in a circling retreat to the west and north, which reportedly traversed over 9,000 kilometers (6,000 miles) over 370 days. The route passed through some of the most difficult terrain of western China by traveling west, then north, to Shaanxi.
