摘要： A method for manufacturing an apparatus with a flow passage includes providing a preform apparatus with a preform flow passage. Flow area of the preform flow passage is determined to provide determined flow area data. The determined flow area data is compared to reference flow area data to provide flow area comparison data. The preform apparatus is chemical milled based on the flow area comparison data.

摘要： A rocket engine fluid-flow system includes a pump fluidly interconnecting a fluid source to a combustion chamber. A nozzle is in fluid communication with the combustion chamber and includes coolant tubes fluidly arranged between the pump and the combustion chamber. An orifice has a throat and is fluidly arranged between the pump and the coolant tubes. The orifice has entrance and exit ramps arranged on either side of the throat. The exit ramp has an exit ramp surface with a divergent angle that is less than a right angle. The entrance ramp provides a smooth approach to the orifice throat. In one example, the exit ramp includes an exit ramp surface having a divergent angle of 20-60°. The exit ramp radius is less than twice the throat radius in one example.
