The gas-turbine powered Plymouth ion built in 1960 had a turbine inlet temperature of 926 C, a pressure ratio of 4,and inlet conditions of 15 C, 0.1 MPa. solve using cold and standard-air assumptions:
a) Determine the back work ration
b) Determine the maximum possible thermal efficiency. compare this to the maximum Carnot heat engine efficiency for the same high and low temperatures.
c) Determine the turbine exit temperature (this would be the exhaust temp.) Do you think this higher than IC engine exhaust?
d) What could be done to increase efficiency observed? Are there any limits on this?
