Quote:

In AeroTech's RMS/Hybrid motor design, pressurized liquefied nitrous oxide (N2O) is employed as the oxidizer while cellulose (C6H10O5) is utilized as the solid fuel (patent pending). Advantages of hybrid propellant technology for the high-power rocket enthusiast include markedly lower cost per flight than solid propellants, less restrictive shipping regulations and elimination of the need to comply with various aspects of the federal explosive laws that currently plague the purchasing and storage of large solid propellant rocket motors.

RMS/Hybrid motors use a high pressure aluminum alloy cylinder to store the liquefied nitrous oxide oxidizer prior to flight. The cylinder/valve assembly is mated to a standard RMS 54mm motor casing and aft closure via a specially designed forward closure/N2O injector plate assembly. The forward closure design includes a provision for a combustible Pyrovalve (patented) which restrains the flow of N2O until the moment of ignition.

Seeing rockets being launched doesn't do much for me...

Unless there were explosives in the head and it was being aimed at something. Smile

That first shot is pretty cool. The one where the camera is attached to the rocket. Smile

what? "those" rockets? or the crummy estes solid fuel ones?

id imagine youd have a bloody hard time getting the bits to launch ones as in the likes of those videos...

that said, i reckon an aluminium N2O hybrid rocket motor would make a good project...

cheers

there was a story on slashdot.org about some australian rocket-nerd attaching video camera and 2.4 GHz transmitter to get live footage from one of these rockets ... (rather than retrieve a camera from the crash site?)

... tho when i last tried his site the movies weren't downloading as it had probably been /.ed
Very Happy
Charles.
