Details of the input variables are given below. At the right bottom of the screen is the output from the program displayed in output boxes. By convention, input boxes have a white background and black numerals, output boxes have a black background and green numerals, and labels are given in red or blue letters. Details of the output variables are given below. On the left is a schematic drawing of the nozzle you are designing.
Flow is from left to right through the turbojet nozzle and from top to bottom for the rocket nozzle.
The exit and free stream conditions are also noted. You can select the type of input by clicking the appropriate blue button at the top right. You can design a turbojet nozzle or a rocket nozzle by using the choice button at the top. While the physics is the same for both types of nozzles, the limits on the flow variables are typically different. A jet nozzle will have a larger throat area and a lower chamber total pressure than a rocket nozzle.
