Free ROV Plans Underwater Ram Jet Plans This little-known type of pro­pulsion was devised back during World War II. It was developed originally for use in naval submarines. The chemical engine works on the principle of the aviation ram-jet. It takes in water, adds a charge of spontane­ously reacting chemical fuel and vents the resulting mass of ex­panding gas through a rearward nozzle. This propulsive jet drives the boat forward just as an air­plane is driven forward by its air-breathing jet engines. Hinged nozzle deflectors can be added to permit braking and reversing. From the Navy's viewpoint the system had one fatal defect. It left a trail of gas bubbles that ascended to the surface and made the sub easily detectable from the air or surface craft. For the sport or working diver this trail would be a safety feature. Possible commercial use of this jet includes: long range cargo submarines able to cross under the Artic ice shelf at high speeeds, cutting down distance and duration of shipments from Asia to Europe and the East Coast of North America. These engines offer long lasting, maintenance free, high performance. After all the engine is nothing but a hollow pipe with tubing to inject fuel.
