Default Tiger pulse jet

Hi guys. I was digging through my grandpas old airplane models and such. We came across this really old Tiger Pulse Jet. My dad seems to think it's from the 50's or around that time.







We don't really know too much about it. I looked around online and found a little info on it. Not sure that the spark plug is stock based upon what I found. But not sure. Just curious as to if it's something that can be used or if it's worth anything. Thanks for any info guys.

That indeed is a Tiger Pulsejet, similar to the US-made Dynajet. Tiger actually made 2 models, a larger one-similar size to the Dynajet, with about 4 1/2 lbs of thrust. The smaller one put out about 2 1/2 lbs of thrust. Both ran on white gas (Coleman Lantern fuel) and were very loud, with no throttling ability. Avibrator/autocoilwas used to provide a spark for ignition, The plug does not appear stock as a standard model sparkplug was provided with the engine -1/4 x 32 thread size. An auto tire pump or compressed air source is also used to start these pulsejets. Once running, the spark coil and air source are quickly disconnected and the engine runs on its own. The tail pipesoon heats to cherry red temperature without any air cooling from flight.
I owned the larger Tiger jet and flew it in controline jet speed events during my late teenage years. Some have intalled these engines in R/C models as Pulsejet Harry can testify. AMA requires a pulsejet waiver to operate these engines for R/C applications.
They are mostly kept/sold/ swapped as collector's items.

I figured it was a more for a collector. I did see some you tube videos with some planes that had a pulse jet installed. No throttling and is loud. Thanks for the info. Know any collectors? Lol

I am not certain, but I believe that the very first engine that PJH owned was the smaller TigerJet. We could never get it to run wirth a darn. He sold it on eBay and got his DynaJet.

As a teenager I once saw one of these pulsejets fly a controline speed demo. It was awesome! It was also the loudest thing I have ever heard in my life. LOL

Is there really an AMA pulse jet waiver requirement? If so, got a link?

Woketman,
Go to: modelaircraft.org and look for their Documents Section.
The pulse jet safety requirements are under AMADoc # 510-Q. The regs are similar to those for turbines but two (2) fire extinquishers are required in addition to a signed declaration that the operator has completed a minimum of 50 flights with a high speed aircraft designed to fly 150 mph or faster. It'snot really a waiver, in the same sense of the wordwith turbines, but the reg must be followed for safety and insurance purposes.

Yes, that was my point. There is no waiver required. Good, looks far simpler to do what's required for pjets. My turbine waiver was a lot easier back when I got it, times have changed!

Po,
That turbine waiver is getting dusty. You need to dust off the turbines and commit aviation!
