Power unit with stored energy

摘要

The weight of a high pressure storage vessel 20 for an oxidant used to oxidize fuel in a combustor 12 which in turn provides gases of combustion to a turbine wheel 10 may be minimized by providing an incendiary device 32 within the vessel 20 which is triggered by a sensor 34, 36 in response to some sensed characteristic of the oxidant within the vessel 20 to increase the pressure within the vessel 20 and to drive the oxidant to the combustor 12.
