Chinese researchers say they have developed a “groundbreaking” fibre-optic gyroscope that is stable across a large temperature range and can be used for navigation. According to the team from the ...

Helicopters have won high marks in Viet Nam doing the chores they were designed for: carting supplies, ferrying troops, evacuating wounded. But, decked out with bolt-on guns and rocket launchers, the ...

Many critical gyroscopic flight instruments, particularly air- or vacuum-driven ones, are prone to mechanical failure (e.g., vacuum pump), which can lead to instrument disagreement. Such failures ...

The device - which uses hollow optical fibres - achieved 'world record measurement accuracy', according to researchers that developed it Chinese researchers say they have developed a "groundbreaking" ...
