Vent Sensor

Postby Voyager » Mon Nov 27, 2017 10:30 am

Has anyone implemented a vent sensor for their hybrid launches? Usually, you can see the venting occurring, but sometimes it is not that obvious, particularly when your launch tower is 90+ metres away. Yes, I have used binoculars, but it would be more convenient to have a very visible indication, either at the pad, or better still, at the LC position with a wireless link.

I'm sure one of you has sorted this out! I did see a post on TRF (http://www.rocketryforum.com/showthread.php?129000-hybrid-rocket-motor-nitrous-oxide-vent-sensor) that describes one pad-based method.

... and I just found this one! https://www.youtube.com/watch?v=ka6EpxNi-YE

I suspect a remote camera watching the vent would be invaluable based on the hybrid launches I have seen. Would take the guesswork out of it fairly cheaply.

Might also help take guess work out of various failures as well.

Maybe something like this is fairly cheap. Only need some batteries and an LCD monitor I guess

I bet there are even cheaper solutions out there.

That's not a bad little system OTT, thanks for that. Could be useful in a number of applications.
