China developing smart rocket able to plot own flight plan

BEIJING: China is developing a smart rocket that can rectify mechanical failures during its flight and plot a new flight path.

The rocket, which is being developed by a project team with the China Academy of Launch Vehicle Technology, will have the ability to perceive, judge, plan and execute flight corrections by itself.

It will be equipped with an advanced reusable power system that can be switched on and off repeatedly.

Based on its flight mission, capabilities and external environment, the rocket can automatically devise the best flight control plan and complete its own space launch.

The ultimate goal for rocket launches is to enter the targeted orbit.

In case of non-fatal malfunctions, such as those that involve non-explosive or non-structural damage, the rocket can respond and make adjustments by itself, including enter- ing emergency rescue orbit and returning to base, to minimise losses.

“If there was an engine malfunction, an ordinary rocket may fail to complete its mission and risk of falling or collision,” said Gao Lei, chief designer of the project team.

The smart rocket, however, could quickly evaluate the situation and its capabilities, and make a new flight plan.

For example, if it loses power, the rocket could maximise its capabilities to set a new target, such as entering a lower orbit, and gradually reach the original target after acquiring orbital transfers via satellites and other kinds of payloads, to complete the mission, Gao said.

Shang Teng, a member of the project team, said that the smart rocket could also reduce costs and all carrier rockets in active service would be upgraded to smart rockets in the future. — China Daily/Asia News Network
