Abstract
A method for manufacturing a liquid fueled rocket engine involves forming a first flange in apposition to a top end of a first tube, fixing an injector head to the first flange to form an inner shell liner assembly, shaping the inner shell liner assembly, forming a second flange in apposition to a top end of a second tube, positioning the inner shell assembly inside the second flanged tube and fixing the second flange to the injector head. Rocket engines manufactured using the method have performance superior to existing rocket engines in at least one parameter.
Claims11
A method for manufacturing a liquid fueled rocket engine, said method comprising:
- forming a first flange in apposition to a top end of a first tube comprising a first metal alloy to form a first flanged tube;
- fixing an injector head to the first flange to form an inner shell liner assembly;
- shaping the first flanged tube of the inner shell liner assembly;
- forming a second flange in apposition to a top end of a second tube comprising a second metal alloy to form a second flanged tube;
- positioning the inner shell assembly inside the second flanged tube and fixing the second flange to the injector head to form an outer shell liner assembly;
- and
- shaping the second flanged tube of the outer shell liner assembly
- wherein:
- said shaping the first flanged tube comprises applying external pressure to outer surfaces of the first flanged tube to reduce a circumference of the first flanged tube at said outer surfaces and
- said shaping the second flanged tube comprises applying external pressure to outer surfaces of the second flanged tube to reduce a circumference of the second flanged tube at said outer surfaces.
