Would we ever see any significant pressure wave produced by a engine working on the Lenoir cycle?

Good Question! "That would be a real quandering" For all intent and propose Rocket Man, confirmed my Answer/Question.
Thanks

Hi Rocket Man
That's great! I couldn't remember where that information came from but I did remember reading it. At first you read everything you can about what interests you (in this case PJ's)
and soon forget where to find it.

The pulsejet uses Barometric pressure the (Lenoir cycle) which unlike external compressive drive such as the Otto cycle's piston, or the Brayton cycle's of the compression turbine, Pulse Jets engine relays on compression from acoustic resonance and barometric pressure. This limits the maximum (pre-c...

My condolences as well.
My Mother was a victim of diabetes and Alzheimer she pass in 2003.

Viv This guy did the welding for me. I could meg weld ok but his work is first class. Remember Eric the guy from Sweden? Here's a link. It was my inspiration for this project. http://www.pulse-jets.com/phpbb3/viewtopic.php?f=2&t=5717&st=0&sk=t&sd=a&start=45 PyroJoe Thanks having the flu sucks! Just ...

I've haven't had a chance to fire them up. Been real under the weather. Just wanted to add these pitchers while I was thinking abou...

Yeah, Doug, really cool. How many boats came out? Anything as interesting as pulse jet power? Hi Mike, Yeah! there were more paddle boats this year. The motorized group was smaller, only 5 and 1 sunk before the race started. 19 total entry's this year. 6 entry's from out of town some from Utah and ...

Here I'm just entertaining the crowed. Fire and loud blast's! that just seems to please them.

White pine County Rec. Ely Nevada Cave lake Bathtub Races Summer of 2011 25th of June. My entry was a twin Lockwood Pulse Jet Engine Liquid Propane Powered. The gasoline injection turned out to be harder to vaporize than I anticipated. However the larger pontoons gave me more flotation. i.e. Less wa...

Put succinctly, water injection = extra massflow = extra thrust. Eric Beck is the man for chapter and verse on it. Here's some good stuff Mark found - http://www.pulse-jets.com/phpbb3/viewtopic.php?f=2&t=4628&st=0&sk=t&sd=a&hilit=water+injection#p54152 Oh, and augmentors. "he wrote compactly but cl...

Given that you'll be running on water, it seems to me that water injection might well give you a handy boost. Hi tufty, Funny you mention that but I’ve already set up another pump from a RV camper specifically for pumping water. Personally, I don’t see any advantage in trying to run on water. But y...

Hello Mike, I was talking to an Ed Dempsey, out in your neck of the woods. I needed some help on an old military 3 phase 4 wire 400 HZ aircraft motor. At first I had no idea who he was, and later embarrassed. He holds the worlds fastest electric car record. At the Bonneville salt flats! 110 miles fr...

Hi Doug I think I would still go with plain old pump gas if I could, do you recall were you came across the high octane making a difference and the circumstances it was run under? we do know that ethanol mix's tend to mess with pump seals and probably alters the performance, downwards or upwards? n...

Hi Doug That's a monster your building there ;-) what did the prototype run like? any pics, are your clamps holding the exhaust pipes able to slide due to heat expansion? Oh and ordinary pump gas will be fine no need or high octane any thing on a pulse jet Viv I read somewhere high octane gasoline ...
