40pounds thrust pulsejet

[deatharena89]

Hello everybody today was my happiest day in my whole life engine got life and looks very powerful take a look at the video.

This is the biggest engine i have ever made, i would really say that PLEASE WEAR EAR MUFFS while you start any bigger pulsejet. Today i experienced the pain of the loudness. Tomorrow iam going to buy an ear muffs for sure, my ears would have been blasted today. You could see at the end i ran away leaving the cylinder and the camera woman ran away. Really i didnt expect so much sound. Used one pair of injectors and fueled only two intakes.

Actually i closed one of the intakes because my tank was only 8kg during starting and after it has been started engine will automatically throw away the cloth and started screaming with high thrust. Engine successfully ran with four intakes. YAAAAAAAAAAAAAY

starting ANY pulsejet without earmuffs is something i don't do. i only run smaller ones, but only two times a year at exhibition flyshows. and on those flights i get restricted to runs of max 5 minutes. well most spectators have enough of it by than anyway with few low passes over the runway
awesome engine you build. need to do some researche into those types of jets. i only have valved jets

Thank you, making valveless is fun as well as irritating because even a small change will affect the overall performance of the engine.
