heya mate here is your answer..........
Start with a well-proven design, like Cottrill's focused wave pulse jet engine. This is a valveless pulse jet designed so that the combustion chamber consists of nothing but a long cone flowing into the tailpipe. Get the plans here.
Materials:
- 22 gauge weldable mild steel sheet
- M10x1.0 metric hex nut
- NGK Model CM-6 spark plug
- Tailpipe Material: 1.25-inch OD "antenna mast" tubing, from Menard's
Tools:
- Pre-designed cone patterns (glued onto manila folder and cut out)
- Fine point PERMANENT marking pen
- Rubbing alcohol
- Leather work gloves
- Eye protection
- Hand operated tin snips - OR - Air-driven hand shears - OR - Air-driven "nibbler"
- Steel pipe mandrel
- Light ball peen hammer or small steel mallet
- Small sandbag
- Electric hand drill OR (much better) small drill press
- Small "half round" file
- Welding outfit and 1/16-inch mild steel filler rod
- Steel tape measure
- Hack saw
- Small "half round" file
- Scrap block of 2x4 hardwood with one rounded edge
- Welding rig and 1/16-inch mild steel filler rod
Step-By-Step:
Build a Chamber
Cut 22-gauge mild sheet steel, tracing a pattern with aircraft snips, to fabricate a two-piece combustion chamber. Using a pipe anvil and mallet, roll a long open cone. Use the mallet to form a blunt dome to cap the cone. Weld each cone's seam. Drill a hole in the dome's tip and weld on a spark-plug mount nut.
