Pulsejet Engine Vertical Launch - VTOL Pulse Jet Rocket

[leviterande]

finally my dream came true VTOl incorporating the amazing Pulsjet, simple, light buuuuut very very hot and loud

[MrMaxclip]

Could you also use it as a rocket engine in space?

[TheNWONOW]

Install a gyroscope stabilization system and let that rip rip free air! 

[cowsrock94]

the only problem with pulse jets in modern tech is that they get extremely hot on their outer surface, and are loud as hell.

[BeckTechnologies]

@cowsrock94 And rocket engines dont?

[rizendell]

@BeckTechnologies Think they could use that to put something in space? It would have to carry its own fuel and the payload... Which would probably mean lots of o2 for operation in a vacum. And Im not sure what that vibration would do to the payload while under the stresses of the atmosphere.

[cowsrock94]

@cowsrock94 I think theres a difference, the body of a pulse jet gets white hot and takes a long time to cool. it just looks like more of a burn hazard to me. And in my opinion rockets make a loud "whoosh" sound that doesn't have the same "oomf" as the noise from a pulse jet.

[DiamondPilotDan]

worlds loudest lantern

[alex0rz]

alright guys...it's time to go global and work as a community to get these innovations in the spotlight. our nations are way too busy trying to win a never-ending pissing contest...

[magnum9987]

You should get gov't funding. Should be easy.

And couldn't you run two combustion chambers through a single exhaust like a Y-Pipe? And then time the pulses to coincide and use the venturi effect to get more thrust and efficiency?

[BeckTechnologies]

@magnum9987 You only get gov. funding if you give the politicians lots of $

[arnold02000]

@BeckTechnologies True. Senators must be greased for favors, especially during election campaigns.

[DynaDuctINC]

@BeckTechnologies But what about the Y pipe thing?

[MultiIPwnage]

IS IT POSSIBLE YOU CAN CREATE A BETTER PULSE ENGINE VTOL, I WOULD LIKE TO PROPOSE A IDEA... MAKE A QUAD PULSE ENGINE PLATFORM SQUARE HAVE THE THRUST FACE DOWNWARD, THEN HAVE A COMPUTER CHIP THAT CAN CREATE A VIRTUAL GRID (SURFACE) AND HAVE IT KNOW HOW HIGH YOU ARE FROM THIS VIRTUAL SURFACE, THEN HAVE EACH ENGINE ONLY INJECT FUEL IF ~ A CERTAIN HEIGHT. THAT WAY YOU CAN HOVER, AND THE SQUARE QUAD ENGINE SHAPE WILL NATURAL STABLE IT AS EACH THRUSTER WILL LEVEL AT MULTIPLE CENT GRAV AT A ALTIUDE

[FireDropTechnologies]

And steam tripples from 370-200 deg. but begins to shrink after that point in temp, but for a rocket? you want it coming in to the exaughst Gas at about 375 deg, F. and cooling as it exits the Tail cone , best if it's fired in pulses like the intaks fuel is, so that it gives a burst of fuel air fire, (jet breaths in)/ Steam hit's exaughst port, (jet fires)

[FireDropTechnologies]

you can compress steam alot like you can compress air.

You can infact compress it back to a liquid, and call it Wet steam

Or super heated steam. This form of steam not only flashes to gassious state

The second it is freed of it's container, but if the temprature it is free'ed in to? Is lower than the boiler temp? It will expand to about 3 times it's super heated volume, untill it cools past 375 deg. or so and starts to shrink volume again.

[FireDropTechnologies]

Your forgetting heat exchange sir, when it hit's the air in your house it cool's drasticly. changing volume. That's why steam cars have a super heater befor the throughtle. But to use it in a combustion chambe of a rocket it only needs to hold super hot volume long enough to displace the air at the tail cone creating thrust, for a millisecond or two, then the rocket is past, and it can cool and shrick volume and no one will give a shit the rocket or you and I. And that 1400 volume at 0 preshure.

[BeckTechnologies]

@FireDropTechnologies I'm gonna have to call BS, you quoted a volume expansion that could only occur in a vacuum pumped full of radiation, and are now googling you're way through steam references. Steam does not expand 5 million times in volume on earth, nor the vast majority of the universe.

[wurft]

let one fly up into te sky!

[BeckTechnologies]

@wurft that sounds like a great idea... just make sure you have a really good helmet before you do so.

[wurft]

@BeckTechnologies A wild pulsejet appears, it used tackle, it's super effective!

[FireDropTechnologies]

See I want too take one of these and Wrap it with some boiler tubeing, and then insulate it with some exaughst header tape, and use it for a flash boiler. So that one could have a boiler that would get red hot in a matter of seconds. Then once hot? you would spray water in to the tube with a nozel like a paint nozel. (As a mist) Better yet? a boiler with the tubes wound in side against the wals of the combustion chamber!

[BeckTechnologies]

@FireDropTechnologies could work! would be interesting to put a steam rocket nozzle on such a device.

[FireDropTechnologies]

@BeckTechnologies

1 ccm of liquid water = 1400, galons by volume of steam .

So by spritzing 1ccm in too a red hot tube you get 1,400 Gallons

of steam. That will do alot of work fellows, alot of work. Look at

Air preshure engins, or the old Case steam tractors, 120hp steam engine,

will make 5,700flb. at 1200psi. Go have a look at the old Doble steam cars of the 20's and 30's.

They used a tube boiler like I was talking about.

[BeckTechnologies]

@FireDropTechnologies I dont think its that high, that would be over a 4 million fold expansion. I think its 1 part water to 1400 parts steam

[FireDropTechnologies]

@BeckTechnologies

Go look at the enthropic chart 1 ccl = 140 galons volume

[BeckTechnologies]

@FireDropTechnologies I'm not sure what charts you're looking at, but the ones I am are saying at 1 atmosphere its about 1.7 cubic meters for 1 kg of water. 1kg = 1000 ml, so 1 ml would be about 1.7 liters. If it expanded to 1400 gallons, water would be extremely dangerous, every time someone tried to boil a cup of tea, all the air would be pushed out of their house. 1 ccm of water would expand to 5 299 576. Thats more than any explosive i know of.

[FireDropTechnologies]

@BeckTechnologies

And yes, think what injecting steam in too the rear of the combustion chamber on one of these would do to the exaughs gas volume!

[FireDropTechnologies]

@BeckTechnologies

Next question!

What happens if you take a Round wheel shaped spool and cut it so it has paddles around the center, then make the paddles part of the intake for the jet. So the sucktion gives the Disk gyroscopic force and acts as a one way valve. then, could you put a motorcycle carb on the intake?, and for start up spin the disk as a forced induction fan? I think so.

[MrNik1001]

In the video you compare pulse jets to conventional turbine jets, are you implying pulse jets can be used to move people? I always thought they don't because of the vibration produced?

[BeckTechnologies]

@MrNik1001 Anything that produces thrust could be used to move people, just a matter of how much the people dislike vibrations. Last I checked a V twin vibrates quite a bit.

[Dookiedolf]

I think you should attach some wings to one of these engines.

A WW2 German V1 rocket model replica would great to see flying.

[matbenn]

That is one angle little engine... Cruise missile perhaps.

[teodormafia]

If you would consider making a rocket, you need to test in on some massive concrete field ;) Did you measure the max temperature it gets to in active zone?

[BeckTechnologies]

@teodormafia We plan on testing a bigger one of these in the winter, once there is a foot or two of snow pack on the ground. :)

[teodormafia]

@BeckTechnologies looking forward to seeing it

[Enigma4072]

Do you think it would be practical to attempt to keep this engine cool?

[teodormafia]

@Enigma4072 as far as material can take this temperature without melting down - it is not necessary. The only problem - placement of the engine, and limiting noize pollution. If these problems would be solved - it can find use in low-budget projects. About cooling - if engine is used in higher grounds or as an engine for flying aparatus, the temperature around it would be quite cold, so partly it would be cooled.

[Enigma4072]

@teodormafia Yeah, that's true. (Thanks for the reply by the way) But, if you made an actual rocket or anything like that with one, what about the components around it? They might not be able to take the temperature

[teodormafia]

@Enigma4072 yep. That is the problem. That is why the position of th engine would play big part in the project. Defenetly it goes at the bottom of the rocket, if there would be fresh air intake from sides, then the hot air would flow down the rocket body shaft. Epoxy can stand temps above 177 C, and Fiberglass has 846 softening point and 1121 melting point, I am sure that properly connected and engine would work all right. The connection could be done by some heat resistant material, foam glass?

[BeckTechnologies]

@Enigma4072 Nope. Jet engines get hot. Rocket engines get just as hot. If you notice he is able to hold his hands and arms close to the engine in order to adjust things and turn it off. Stainless does not radiate heat away like other metals!
