Making missile doors part 2 ...







Much better second time around

Hi Ramesh,
thank you for the fast answer. Super work. Greeting Steamtrucker

hi Ramesh
do you have any plans/pics about your working missile system?

Hi Heiko, sorry no plans of my own, only the Japanese ones for my propel torpedos...

I have two choices, either like my propel torpedos (make it larger like Matt Spade design)
Or Compressed air like this

£ 120 per unit, not bad! :shock:

the torps, are they working now? how do you refill them? and what dimension has the nozzle inside? have you tested the maximum pressure?
a lot of questions, i know

Regards
Heiko

EDIT:
I have found one info: 0,6mm nozzle-diameter.
and how do you store/start the torp?

Hi,
Yes the Torpedoes are working. Uses butane gas (lighter fluid refill). The fill adaptor is inside the nose cone The rear nozzle is 1/16 inch OD. Inside is a medical needle (maybe your right about 0.6 – 0.8mm). Smaller diameter makes it go faster. I don't know what the pressure is. It is not as much as using airbrush propellant. The pressure is not great, you can hold the torpedo with 2 fingers and remove the end cap. It is low power, it won't fly through the air (too heavy). For missiles I think you should use airbrush propellant and make it out of plastic tube to make it lighter. The fins are straight but it still goes nearly in a straight line. 1 oring is enough to seal and hold the nozzle in place. To charge, you must first place the end cap on the nozzle. Then place it through the front of the torpedo tube. A mechanism hold the end cap in place. To launch you use a servo to 'push' the torpedo off the end cap. Torpedo stops when it runs out of gas – about 15 meters on full charge.
