10 Lb Thrust Beck-Technologies Thermojet Valveless Pulsejet Engine -
All TIG Welded Stainless Steel


$300.00 USD + Shipping

Due to the ever increasing price of stainless, the price may increase in the future, although I try to keep things as reasonable as possible.

This thread is a copy of my ebay auction listings, you may see these engines on ebay, better known as feebay, but we do not have them listed 100% of the time, but you can still purchase directly through us using Paypal.

We can also do custom modifications of any of these, such as different materials, injection orifices, pressure taps, and heat exchange coils etc etc.

___________________________________________________

This thread is for a brand new 10 LB thrust Stainless Steel Thermojet style valveless pulsejet engine, with duel intake stainless fuel injector, spark plug, and a copy of my Pulsejet CD with tons of pictures, tutorial videos, instructions, and plans to build your own engines.

A valveless pulsejet is a type of jet engine with zero moving parts, and that produces thrust by burning fuel in pulses. Owning a pulsejet is a great way to get into hobby jet propulsion without spending $3000 or more on a turbine system.

The engine is made entirely from 20 gauge 304 Stainless Steel, and is fully TIG welded so that it is completely leak free. This is not a leaky spot welded junk engine that you may see here on ebay from time to time. Unlike the notorious spot welded thermojets being sold on ebay, this engine is rock solid and will not leak fuel / compression / exhaust and can be run over a very large throttle range, because of the unique characteristics of the engine, and its leak free construction, it can be throttled down to well below 5% max thrust.

It will "self start" and you can throttle it down to a very low idle so that it is quieter than a lawn mower, then instantly crank it up to max throttle for ground shaking power!

Image
The engine is brand new, not run at all. It will stay just as shiny in the picture until it is run for a while.
Even though the engine is not sent to you test run, its built to exact dimensions and guaranteed to run.


Its 20 gauge wall thickness means that it is light, but still plenty strong for extended static test runs without cooling air. The engine is 37" long, about 38" with the spark plug in place, and weighs in at 3.75 lbs.

A mounting stand is not included to make shipping internationally easier and keeping box size to a minimum, though if you are in the US and want a stand I can include one built to your design for extra.

The engine has a CM-6 size spark plug. The spark plug is not essential for starting, by using a small hand held torch the engine can be lit by holding a flame at the intake while turning on the fuel, but for instant reliable self starting you can also use a spark ignition system, giving you more options.

The Thermojet is a very interesting design. It has two intakes, and a fuel injector going into each intake. With propane as the fuel source, you simply need to provide a way to ignite the fuel for the engine to start. This behavior is called "self starting". The force of the fuel flowing out of the injectors pulls in additional air and mixes it in the combustion chamber, when this mixture ignites, the engine creates a pulse of thrust, and it is enough to start the repeating cycle of taking in fuel and air, burning the fuel air mixture, and expelling it out the engine at high speed.

Most pulsejet designs require some way to blow air into the engine in order to create the proper fuel air mixture in order for it to ignite and self sustain, typically air compressors, shop vacs, or leaf blowers. This adds another level of complexity to starting an engine, but this 10 lb thrust thermojet is self starting, so the starting procedure is extremely simple. Below is a starting tutorial video, the engine is the exact same design, built with the same techniques and welding jigs, to the same dimensions.

This engine can also be run on almost any kind of liquid fuel. Gasoline, kerosene, diesel, methanol and more. The engine will gladly run on almost anything flammable you can pump inside it. For best results with RC liquid fueling, a small liquid fuel pump like used with turbines will work best. To make starting on the flight field just as easy as using propane only, the engine can be started with a removable propane fuel injector, set at a low throttle. Once the engine is on a low idle from propane, then turn on the liquid fuel and throttle it up a ways, then shut off and remove the propane.

This engine is brand new and un-run. Even though it is not test run, it is built to exact dimensions using all the same tools, techniques, and welding jigs, as the engine in the video above, and it is guaranteed to run. Building your own engine can be a difficult process, there are many factors in building and running your own engines that can be a nightmare to work out and make everything work together on the first try.

This engine would be an excellent way to gain tons of experience if you have had limited success with building your own engines in the past, and the Pulsejet CD included with it contains tons of information, along with the plans for the ThermalPulse 180, and Chinese Valveless pulsejet engines. These designs are highly refined and combine ease of starting with excellent all around performance.

Image

The CD contains lots of extras beyond the plans; it is a comprehensive collection of documents, diagrams, and programs that go way beyond the average simple one page engine drawings that are normally found online.

There is a ton of information included on this CD, including pictures, videos, video tutorials, and "how to" documents on everything from finding materials to starting the engine for the first time, all 100% original content created by me. The Beginners Reference Book has all kinds of helpful information for beginners and the Advanced guide goes into more challenging and high performance methods for when your ready to move onto more in depth projects.

Covers of the Builders Guides, PDF format, can be printed with extreme print quality.



Warning:


Even small pulsejets are not toys, they are jet engines. They are intended for mature and responsible hobbyists. They produce tons of noise, glow orange hot, and shoot out high-speed high-temperature exhaust gas. By following a few simple safety steps pulsejets can be a very fun and safe hobby, but you should understand that there are still risks associated with things that glow orange hot, use highly flammable fuel, shoot fire, and produce tons of deafening noise. The safe and responsible use of this engine is entirely up to you.

You should always wear hearing protection when running the engine, along with safety goggles at all times. Anyone near the engine should also be provided with hearing and eye protection as well. Wearing a good pair of leather welding gloves is also a good idea if you plan on adjusting things around the engine. Pulsejets get so hot that if you mount them close to flammable materials, the radiant heat can cause them to melt or ignite. Do not run them indoors or near flamable materials.

I get a lot of questions whether or not these engines can be run indoors, the answer is NO! I know some of you really want to run a jet engine in your living room, and blow out your windows and light your wife's new drapes on fire, but just dont do it! If people are always saying you dont have any common sense, maybe jet engines arent for you.


Once again this engine listing is for:

10 Lb Thrust Stainless Steel Thermojet Pulsejet Engine with spark plug

Dual intake stainless fuel injector line optimized for propane.

Pulsejet CD with Chinese Valveless & TP-180 Pulsejet Plans + tons of pictures, videos, tutorial videos, documents, and more.

Extras you can purchase for this engine:

Mounting and display stand $20 with purchase of engine ( USA only, the size and shape make it difficult to ship internationally for a reasonable price)

Light weight aluminum thrust augmenter $40 with purchase of engine.

If you wish to purchase these items you need to send us a message before completing your checkout so they can be added to your checkout page.

SHIPPING

Shipping in the US will be by priority mail unless other shipping method is requested.

International shipping available by USPS Global Express Mail, which comes with tracking and insurance.

For international orders customs can sometimes be a delay, while the majority of items go through quickly and without incident, if you do not get your item in a timely manner do not wait weeks or months to to say anything!

------------------------------

Pulsejets, even small ones are absolutely not toys, they are for mature and responsible hobbyists. They get orange hot, and produce so much radiant heat that they can burn things close to them. They are also EXTREMELY loud. Pulsejets can be a fun and safe hobby if you follow a few simple safety rules like wearing hearing, and eye protection, and keeping the engine away from any flammable materials.

Hi Eric,

Thanks for the post, I am really interested in this model and tried a while ago to contact you via email and private messages but got no reply :-(

What is the shipping cost to Zurich? How do you prefer to continue the transaction? Do you have a preferred/private email? If so, please send it to me as a private message.

Regards,
Iyad
