LOHAN ideas..


Re: Launch rail and backplate issues

Analysis of the previous launch shows that the balloon horizontal speed increased up to a specific altitude after which the rise was almost vertical. Indicating that the wind speed at launch should be negligible.

As far as the backplate is concerned I still maintain that the vertical launch tube is the bets option. The veritcal arragment prevents issues of launch swing and the tube can be used to reduce freezing problems. It would be possible to seal the tube completely by blocking the 'muzzle' end with wax paper, cling film or a light cap so preventing ingress of moisture. This blockage (or could we say hymen) would be broken on launch either by the launch vehicle or it's exhaust gasses. The tube could be loaded in a dry as atmosphere as possible and something like silica gel could be included to further prevent moisture build up. The tube can be insulated by expanded polystyrene to reduce the freezing effects further. maybe chemical hand warmers could be included too.
