4LB Thrust Thermojet Pulsejet Overview and Tutorial

This is a overview and tutorial video showing the Beck Technologies 4lb thrust thermojet.
The engine is a valveless pulsejet with no moving parts, and easily self starts on propane, just turn on the ignition and turn on the fuel....
A valveless pulsejet is a unique type of engine with no moving parts. Unlike ramjets, which must have air blown into them at high speed, either by a blower or by traveling very fast, pulsejets can run while completely still.
They can be throttled typically between 10% and 100% thrust in the blink of an eye, and dont require any spool up time like turbines or turbojets.
Because they have no moving parts, valveless pulse jets are much easier to own and operate than RC turbines. For the cost of a ducted fan setup, you could have your own real, high speed RC jet plane.
The truth is that by the time you add up turbojet planes engine weight, fuel and oil pump weight, the computerized control system, and any onboard starting systems, you not only have a small fortune invested in the plane, but its also quite heavy. Pulsejets can be made extremely light weight, and even valveless engines are capable of pumping their own liquid fuels by the venturi effect. All you then need is your standard reciever and servos and a small battery to power it, rather than a large battery to power a fuel pump.

you make some really cool stuff man, good job
That is very cool!! Your videos are so cool and informative and thats why I subscribed to your channel. The only pulse jets I have are Reynst pots but when I get that welder I'm gonna make me a jet bike.
what did you use as injectors (the small rods going into intake) and how did you manage to hook it up to torch line?
nice man. what's the thrust to weight ratio on one this size?
Can you tell me how far did you put in the fuel lines into the intake?
seem it might be a good idea to have a flash back aresstor on the fuel line and the combustion chamber seem to get hot enough to almost melt
Can we make it run on Keosene or HSD ? and how small can you make these? how about 12"
What happen if you put a after berner on the trust ametator by injectig fuel to it
Is there a way to calculate the dimensions for an engine like this?
I have built the same engine, but it dosn't self start, it does work, I just have to blow some air in. I have 2.5 mm (inside diameter) steel tubes. Anyone have any idea why it dosn't self start?
It doesnt, the engine re-ignites from the pressure pulses, go to our site and you will see a very informative flash animation.
Looks damn good. How economical is this? Like how long would it last on say 5lbs of propane?
need a bigger one for a gokart, but they will work great.
How does it get air??
Yes, they all can propel a plane
I want a thrust Augmenter. Can anyone tell me how to phone Beck ?? They do not answer any e-mails.
how amount of fuel use?
I'm a professional stainless steel fabricator/ welder, looking forward to building a thermo pulse jet, your vids and site are great but now I'm needing a decent set of plans, plenty on the internet but I would rather use a tried and tested design from yourself, could you please let me know if you are going to upload any plans? if not can you recommend a good thermojet plan, you can trust that I will build with precision and show the final test run on my channel 😀

This would work better is the engine's hull was made of a Cobalt alloy like the X-15. Tungsten is too heavy, but then again this is a static test
cool
Tremendous amount of white hot heat for 4lbs of thrust
it can work by gas feul
How does the spark plug keep sparking after you remove the wire?

it dosent
Where can I obtain the plans for this engine? I'd like to build one myself.

that's fuckin sick
Why not put cluster of these kind of engine for air craft

Can’t believe I’m responding to a 5 year old comment but whatever. The engines just don’t produce enough thrust and aren’t efficient enough, that’s really it
