 Here are a couple videos of pulse jet engines
being run. The top one is a home-made pulse jet engine mounted on an R/C Long EZ.
The bottom video presents a short tutorial on how the Dyna-Jet is built, how it
is made, and how to start it.
Here is an article in the 1946 issue of Popular Science magazine
entitled "Baby V-1 Jet Flies for Fun," which may be one of the first mentions of
the Dyna-jet engine, which was developed by William Tenney and Charles Marks of
Minneapolis, Minnesota. It was later marketed in the 1950s by a company named Curtis Automotive Devices manufactured the
now-coveted Dyna-Jet engine (they typically sell for >$400 on e-Bay --- if you
can find one).
Are they still around today? Yep, only the company name is now
Curtis Dyna-Fog. One of the first pulse-jet products aerospace engineer Russell
Curtis produced was the Dyna-Jet "Red Head" miniature engine for use in
model rocketry (per their website).
This advertisement was scanned from page 57 of the June 1957 edition of American
Modeler.
According to the U.S. Bureau of Labor Statistics'
inflation calculator the $35.00 price in 1957 would be $339 in 2021 money.
Below is the e-Bay auction mentioned.
