Claims
- 1. The method of making a hydrazine fuel injector comprising, shaping a piece of high temperature alloy to a frusto-conical shape, making a series of machining cuts in different planes radially of said piece, said cuts in certain radial planes being completely through said piece and cuts in other radial planes being of variable depth to form a series of integral feed tubes arranged in two radially spaced-apart circular arrays.
- 2. The method of claim 1 wherein said tubes each have a flow passage lengthwise thereof.
- 3. The method of claim 2 wherein said machining cuts and flow passages are by electrochemical machining.
- 4. The method of claim 1 wherein said machining cuts are made by electron discharge machining.
- 5. The method of claim 1 wherein the cuts made in said other radial planes also vary in depth lengthwise of said piece to have the feed tubes in the inner circular array diverge from fuel inlet to fuel outlet ends thereof.
