Our launch windows are dependent on the NSWRA launch schedule, as that is when we get access to the launch site and have the altitude clearance.George Katzhttps://www.blogger.com/profile/05735356042927822858noreply@blogger.comtag:blogger.com,1999:blog-38795037.post-88307016014440859922012-01-26T09:00:04.542+11:002012-01-26T09:00:04.542+11:00Hi George,

We are designing it so we could use full bore (22mm) nozzles on the boosters, as well as a larger central nozzle. The target launch pressure is 250psi (~17 bar).George Katzhttps://www.blogger.com/profile/05735356042927822858noreply@blogger.comtag:blogger.com,1999:blog-38795037.post-83564800872105337872012-01-25T03:10:15.779+11:002012-01-25T03:10:15.779+11:00Hi George,
What kind of rocket will the Polaron G2...Hi George,<br />What kind of rocket will the Polaron G2 - Phase 2 be? <br />To get a force of 3000N, you need a high pressure and/or large surface for all the nozzles together.<br /><br />The rocket I' planning will be launched at 8 bar with max 3x Ø22mm nozzles and 1x Ø9mm nozzle. That makes only 962N of pulling force.<br /><br />It seems that you can't launch on Saturday due to the weather conditions. <br />If we can believe it, next weekend (04/02) it will be dry and with not too much wind...<br />A good site for weather prediction : http://www.buienradar.nl/weersverwachting-plaats.aspx?bron=3&lat=150.867&lon=-33.7667&naam=doonside&cnl=Australi%C3%AB&c=AustraliaJanhttp://www.bloggen.be/jfwaterrockets/noreply@blogger.comtag:blogger.com,1999:blog-38795037.post-76321086071871591772012-01-24T20:04:29.281+11:002012-01-24T20:04:29.281+11:00Thanks guys.
