A few examples of the new PJ8C (with internal ceramic coating) are still available for US$299 including shipping by EMS international couriers with track and trace (where available). The video below shows the original revised PJ8 prototype installed in a Chinese ARF Long-EZ.
Although there are other pulsejets for sale on the net, few (if any) have been proven suitable for model aircraft use -- often being too heavy, lacking in thrust, too sensitive to fuel-head or requiring an inconvenient fuel such as propane. The PJ8C has its own fuel pressurization system that eliminates the effects of high G-forces and eliminates the need for an expensive fuel-pump. It is also built from 0.5mm stainless steel, then coated inside with a special layer of ceramic to improve performance, reduce radiated heat and extend engine life.
NEW: See how they're made.
PJ8 combustion-chamber/tailpipe units These bodies come with a full set of plans and a project-construction guide that covers machining a valve-plate and making the other components you'll need to build a full-blown, flight-ready pulsejet. Sorry, sold out. contact me if you want one from the next batch.
Ignitor units |
New batch of engines available
These little black boxes drive a regular car ignition coil to provide a spark
hot enough to start any pulsejet engine. They're small, convenient and robust.
Each unit has two LEDs to indicate when they have been connected to a battery and
when they are sparking. Having a reliable spark source makes starting your
pulsejet engine much easier.
Sorry, sold out.
