Rotary Hingeline Actuators and Velocity Summing

There is another CR4 thread, "Unbelievable Terminology...", that is a spoof consisting entirely of double-talk. It would be a formidable translation exercise. (All the more so if the destination language has no concept of this type of word-play.)

The advertising hype is almost as bad, but maybe not quite. Someone familiar with this might "get it," but for anyone else, it is very unexplanatory. You might not have the option of rejecting incomprehensible input, in which case my sympathies, but if possible you should bounce this back to the source. They don't necessarily have to make it fly to the Chinese, but they do need to make it comprehensible (jargon-free) to the translator.

My interpretations:

1. a rotary hingeline actuator

An actuator which operates like a hinge with a built-in motor - the sort of thing that could be used to automatically open a door or the lid of some enclosure for example.

2. velocity-summing

A gearbox like a car rear wheel drive differential, but used the other way round. Put motors where the car wheels would have been, and the prop shaft speed (which now becomes the gearbox output) will be the sum of the speeds of the two motors.

If one motor failed the output shaft would still rotate, but more slowly.

Re-reading the OP, it mentions "control surface", so presumably this is an actuator for e.g. an aircraft wing flap of some variety (hence the need for redundancy).

I tried that link but it seems that there is something wrong with the link.

got serveral web links. Share with you guys

Sorry, Wingman...

I just tried it, and it worked for me. It is a pretty slow load. Did you give it enough time?

It sort of looks like you found some answers anyway.

Thanks for the GA, guys.
