"The success of the test run indicates that we have already mastered the technologies of designing, producing, manufacturing and testing heavy-duty engines, which is very meaningful for future development of heavy-duty boosters. Next, we will make an integral solid-fuel engine with a fuel load of 145 tons and a thrust of 400 to 500 tons."

"Numerous tests are mainly focused on the ground ignition of hot test runs. Only by doing so can we get the data on engine's working pressure and thrust. These results of the engine performance will be able to be applied for the overall rocket. Then we can use the actual thrust and working period of the engine to calculate how much the carrier rocket can carry and how high it can fly."

"As the current technologies are quite mature, a couple tests of an engine on the ground can collect all the data we need, and then we will know if the engine is qualified for its maiden flight. After its maiden flight, the ensuing fights with payloads will also be a gradual verification for the engine's reliability."

The first test run on China's latest solid-fuel rocket booster engine succeeded in Xi'an City of northeast China's Shaanxi Province on Wednesday.
It is China's first three-stage solid-fuel rocket booster engine with a diameter of 3.2 meters that is for commercial use. The rocket engine can deliver a maximum thrust of 260 tonnes, and was ignited for more than 130 seconds during the tests.
Developed by the Academy of Aerospace Solid Propulsion Technology under the China Aerospace Science and Technology Corporation, it is China's most powerful rocket booster engine.
In the future, it can be used for China's large and heavy-load rockets to meet requirements in advancing space equipment, manned lunar-landing and deep space exploration.
"The success of the test run indicates that we have already mastered the technologies of designing, producing, manufacturing and testing heavy-duty engines, which is very meaningful for future development of heavy-duty boosters. Next, we will make an integral solid-fuel engine with a fuel load of 145 tons and a thrust of 400 to 500 tons," said Ren Quanbin, an official of the China Aerospace Science and Technology Corporation's Academy of Aerospace Solid Propulsion Technology.
The test run is a crucial part in engine development. It aims to verify engine performance, design feasibility and technological reliability. This is a task that must be finished before the engine can be used in an official launch mission.
"Numerous tests are mainly focused on the ground ignition of hot test runs. Only by doing so can we get the data on engine's working pressure and thrust. These results of the engine performance will be able to be applied for the overall rocket. Then we can use the actual thrust and working period of the engine to calculate how much the carrier rocket can carry and how high it can fly," said Wang Jianru, chief designer of solid rocket engine.
In addition to testing whether the engine is competent for launch missions, the test run is also a valuable summary of experiences. It could provide guidance for the later improvement on engine's design and performance.

The engine that went through this test run is a technological verification engine. Its success shows the progress China has made in the development of solid-fuel engines.
