the energy that goes into pressuring the propellants isnt waisted that energy is converted to KE too (through the injectors and as pressure drop across the nozzle) if we are assuming perfect environment of course
i think the reason it stops spinning is "real world" friction etc in an ideal environment it would accelerate till it reached C lol -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Ian Woollard Sent: Monday, June 14, 2004 12:20 AM To: [EMAIL PROTECTED] Subject: Re: [ERPS] Re: Tip nozzle paradox Stump wrote: > So we are generating thrust by the centrifugal pumping action alone, > then heating the fuel? No. The scenario is that we are predominately generating the *pressure* by the centrifugal pumping action. The propellent undergoes an exothermic chemical reaction in the tip rocket liberating gaseous fluid that exits through a De Laval nozzle. Clearly there is something impossible in the problem description; otherwise there would be no paradox. The puzzle is: "what is wrong?" _______________________________________________ ERPS-list mailing list [EMAIL PROTECTED] http://lists.erps.org/mailman/listinfo/erps-list _______________________________________________ ERPS-list mailing list [EMAIL PROTECTED] http://lists.erps.org/mailman/listinfo/erps-list
