Pulsejet-powered Long-EZ (part 2)

[Snapx4000]

your pulse jet dont work fine

[NYRugbyPilot]

why are the kanards so big and bulkey?

[Viper6454]

Still don't see why you need to be so dramatic over this.

[suldubulduu]

where is the gas ? what is fuel economy on this pulse-jet (how much liters per minute)?

[0fVolfAndMan]

is that a pertronix flamethrower ignition coil

[imSMD]

i dont know if you will answer to that question but..

can you make a tutorial about how did you make the pulsejet please

[Dre4dwolf]

If i strapped like 20 of these to my back? ;)

[TheTruthHurtsYup]

Epic Beard Mans brother.

[bamfest4life]

how did i get from rc car videos to this

[Celis215]

@bamfest4life lolz, i was actually searching for skateboard fails but realized i was here in this category... LOL!

[sonnytiger]

That is really cool, that thing glides magnificently!

[straighttailpilot]

Wow that is very interesting. I had never heard a pulse jet before. sounds just like a normal engine but cooler.

[TheYodoc]

You had plenty of altitude to turn back to the runway.

[thehacksrule]

nice landing

[ebr62933]

Don't your ears just love it when this thing quits. Every thought of building a Fieseler Fi103?

[sheepball]

nice



[69arildodildo]

Good one! Is it possible to throttle a pulsjet?, and, how small can they be made? Best regards,

[JlkJlk18000]

How do you keep it cool? I created one that worked on a oil cooled version and had the actual pulse jet inside the body of the plane with oil coolant which was circulated (and cooled I might add) all by the wind generated from flying... If you dont have anything to cool it (aside from it being outside the plane) how long can you fly it before it over heats? (or does it at all?)

[zambodiazook]

That was totally awesome! Well done!

[Palexb14]

Could a pulsejet be put onto a real plane, or aren't they that efficient?

[SirDeanosity]

@Palexb14 My assumption is the noise would to great to be legal.

[fbenzeno]

awesome plane and setup, but ill stick to electric planes :)

[uarequeer]

wow good job man how many hours does it take u to make one of those? and is tyhere any practical use for these or is the thrust at that level not there? also wut is the fuel consumption of these things? is it more or less then a normal jet... lbs of thrust compared to amount of fuel?

[MRjesseNL]

vuvuzela?

[hamood128]

Not to put any of you Aiejreb by mobile camera

And paste the aircraft and photography and put it in YouTube

[Sumermagor]

LOOK AT 1.28, what goes past there? UFO?

[whynabile]

IGNITION AT 1:00

[A5runner]

still nice landing!

[mrwiggles2]

Very cool.

[mintkendishin]

its a fart jet

[highmountain0]

@mintkendishin lips:)

[gamesbok]

Side-slip to spot land anywhere you like.

[SvenOkonomi]

Glides well dispite the anvil on its back. :P

[KnightChatX]

That's like Buzz Aldrins Tulsa's Rocket Racers, nice.

[butterfly01princess]

LoL......

[TheZanahorias1]

Its cool, but its not the quietest thing in the world...

[PotholesInMyLawn]

Almost sounds like the real thing

[curea229]

Nice. But how are you getting the pulsejet going without any ram intake?

[SvenOkonomi]

That stuff is what dreams are made of. :p A nice big weird and noicy plane. Excellent stuff. *subscribes*

[gonitronow]

the ram-air intake causes the reeds to remain open at high speeds. i would suggest a change in intake orientation because it will go MUCH faster with reeds that close at high speeds

[turbomiata007]

damm good flying

[Flight1142]

Can you tell me please where did you get your pulse-jet? Thanks and great flying!!!

[xjet]

@Flight1142 I make them and sell them for $299 including shipping. I only make small batches though and there's a waiting list at the mment

[Flight1142]

Thanks for your response and congratulations for your work. I think price is reasonable but I have some additional questions: Can you tell me what is the size of an equivalent glow engine to your pulse-jet? What type of fuel does it uses? It looks a little bit noisy too, I am right? Would I need something else to put it on on a given airplane? Thanks.

[gogogeedus]

I'd like to have a go at a pulse jet one day,thats about number 5000 on my [to do] list.

[boorelius]

@gogogeedus

same for me

[ravijagdev]

hey, what fuel r u using? and does that spark plug keep sparking after u take out the thing u ignited it with???

[DragonToko]

Nice piloting!

[danebrewer10]

is this the engine they put in the V1 rocket? it looks pretty similar plus is sounds about the same.....

[Prod1Kh]

@danebrewer10 Yes, it is.

[1HumanKind]

@danebrewer10

the V1s were powered by pulse jets yes. "buzzbombs"

[wtfah67]

nice power cap.

[swishersweets666]

are these more efficient than car engines?

[96bikerider96]

i want to make one

[swordofpassion]

great job

[BlakeMason2]

That sucker just lept up into the sky--great thrust.

[discoape]

Good choice not to turn around on a test flight.

[danielgosson]

Can you vary the thrust or throttle on these or is it just full on or full off?

[xjet]

You generally have full power or nothing. Pulsejets can be made to throttle to a degree on the ground but once you're in the air the ram-effect of the airflow tends to cause them to run too lean if you try to throttle them to any degree.

[fil2efly]

Oh its a glider now. Brillant

[CorruptH3ro]

how does the pulse jet f dif from any nitro rc jet can anyone tell me

[elliotmotoX]

thats awesome, sounds like a little 2 stroke nitro car

[Flight1142]

A different kind of propulsion for a RC model, cool.

[Indianmalujl]

so is this still deflagration right?

[xjet]

Yes, it is deflagration.

[adarshramanathan]

how fast does it go?

[xjet]

Check out my latest video to get a better idea. We clocked it at about 170 with a radar gun last weekend.

[zyoungson]

wow great plane, great to see something different

[gatmack]

doesnt sound like a jet

[xjet]

It's a pulsejet. Unlike a turbine, a pulsejet works by repeatedly exploding a mixture of air and fuel in the body of the jet and using the ejected hot gases to create thrust. The same kind of engine as use don the V1 flying-bomb. Google: pulsejet for more information.

[SthealthRaider]

hey i got a question sooo u only need to ignite the spark plug one time ?

then it all ignites itself?

[xjet]

That's right. Once the engine is running the ignition is turned off and disconnected. It will continue running all by itself. See my other video on how a pulsejet engine works for more info on the theory behind these engines.

[vollrathj]

can you cut the power down any time or you gotta wait till it runs out of fuel?

by the way i visited your 1 tree hill while on a stop over going to samoa...

[noonedude101]

Buzz Bomb!!! lol

[stealhty1]

come you could easy make 180 and land at front of you,may be too much of an plane

for you ,lol

[thebigbrownbox]

so pulse jets aren't throttleable right?

[xjet]

Valved engines can be throttled when run statically but it's not really practical to throttle them when they're in the air due to the ram-effect which tends to simply make them lean-out and stop.

[thebigbrownbox]

makes sense. Great work btw!

[xjet]

Check out Part 3 (see video responses) for a longer flight now that the fuel system is fixed.

[RCSuperPowers]

Great work!

[RoboTekno]

nice job, well done and nice save.

[2m1986]

Good! Very Nice!

[3DBlockBuster]

Bruce, just watched your Junk Yard Wars, that was pretty cool. Can't wait 'til you square away problems and have a movie of flight 'til the last drop :); Oh and of cause a ProBro vid. Do you have a preview on YT already :)

Awesome job!

[Tripp393]

can it kill people? like it should?

[xjet]

Should it?

[Tripp393]

shouldn't it?

[3DBlockBuster]

Tripp393, why should it kill people?

[cheetah100]

The ultimate in stealth technology :)

[xjet]

Yep, once you've deafened them with a pulsejet they won't be able to hear the battalion of tanks advancing on their positions :-)

[spasdirect1]

I will borrow Barry's hearing aid.

[xjet]

Even Barry had to put his fingers in his ears :-) (and for the benefit of those who wonder what we're talking about - Barry is a fellow club-member who is *very* deaf already)

[spasdirect1]

Great Bruce, wished I was there. Maybe next Sunday

[xjet]

Bring hearing protection :-)

[Brobolio]

Awesome!!!

The sound is crazy, cogratulqations on the maiden.

Saludos.

[bluedog1976]

Well done my friend. Your neighbors must love you when you crank that puppy up in the shed.

[POPPAVALIUMANDROPOV]

Good job better luck with the next flight

[xjet]

Now that I know the airframe has no vices I'll be able to throw it around a bit more next time and with a new fuel filter I should get the full 2-3 minutes of flying that 20oz of fuel should provide :-)

[JasperPalmer]

What would have happened if you had turned it into the wind?

[xjet]

Well as this was the first flight of this plane and in an unmodified form they tend to have some nasty flying characteristics, I was worried that it might have stalled while turning back towards the runway so I decided to play it safe. As it turns out, my modifications have meant that it is a very docile flyer so I could have done the turn easily without any risk. Still, it's always better to be safe than sorry on a test-flight.

[storchnuts]

Your a worry Bruce LOL keep it up looks and sounds bloody GREAT cheers Frank

[statesy1]

Well done, hurry with the next vid..
