| Abstract: | The basic idea of the LN 2 propulsion system is to utilize the atmosphere as a heat source to vaporize and superheat the cryogenic liquid nitrogen for use in a thermal power cycle.The new LN 2 powered system is different from traditional cycle systems.It adopts both the LN 2 cycle and the traditional oil powered cycle.It can utilize the waste heat of radiator and automobile exhaust in the traditional oil powered cycle to enhance thermal efficiency and lower waste heat pollution.Practically the three stage expansion two reheat process is the best expansion process to attain the maximal specific power.Also the design of the new frost free heat exchanger has been investigated,and the design rules have been worked out |
