Our jet-engine plans fully detail the construction of not just one, but 2 extraordinary pulsejet engines! Full construction prints are provided for both engines. These pulsejets are easily built from materials that can be obtained for $200, or even less, making them among the most affordable sources of power available. Although lightweight and compact in size, each engine can produce an amazing 25 to 37+ lbs. of thrust—power that is readily adaptable to a wide spectrum of air, ground or water-based vehicles

Unlike simpler ramjet engines, the pulsejet can be started from a standstill and is much more fuel efficient. The pulsejet achieves its performance edge by use of an intake valve that is sonically resonant with the engine's tailpipe. The vacuum and resonance created by the thrust of the exhaust opens the intake valves to admit a fresh fuel-air mixture, while the combustion then reseals the valve, and the cycle repeats. Thus, the key to a pulsejet's efficiency lies in the construction of the valve and its sonic attunement.

One of the very special features of the pulsejet is its ability to run on a variety of fuels, including regular gasoline, diesel fuel and kerosene. It is this versatility combined with its simplicity and low cost of construction and upkeep that will make this project highly rewarding.
