Hello all I am currently building a couple of pulsejet engines for testing with a veiw to use them in an ultralight plane. These engines first came to fame for being used on the world's first genuine cruise missile, the V1 "doodle bug" or "buzzbomb" used by the Germans in WWII. There has been a lot of researh done on them, and I intend to make these engines primarily for use by the R/C model fanatics, and possibly for a few speed boat freaks who want to really push the envelope on the water. I'll attach a nice little app i got to design these engines if anyone wants to give it a try. Happy Landings! Pete.
