U.S. Navy Develops Revolutionary Ram Jet Engine – Vintage Photograph

The U.S. Navy Department has successfully developed working models of the Ram Jet, a propulsion system for supersonic flight up to 1,500 miles per hour. Known as the “Flying Stovepipe,” this engine weighs only 70 pounds and operates without moving parts. Oxygen is compressed by the jet’s speed, fuel is injected, and exhaust exits the rear opening. Unlike rockets, the ram jet uses oxygen from the air.The U.S. Navy Department has successfully developed working models of the Ram Jet, a propulsion system for supersonic flight up to 1,500 miles per hour.

M 1103 Pertin BILDSERVICE THE “FLYING STOVEPIPE” US NAVY DEVELOPS REVOLUTIONARY RAM JET ENGINE 12-6-46 Development of successful working models of the Ram Jet, a means of propulsion for flight at supersonic speeds up to 1,500 miles per hour, has been announced by the U.S. Navy Department, Termed the “Flying Stovepipe” because of its form and fact that it has no moving parta, the complete Ram Jet weighs but 70 pounds. Its operating theory has been known for more than 30 years, yet it remained for the U.S.Navy scientists to perfect those principles that have rendered the Ram jet a practical method of achieving high speed flight at high altitudes. Oxygen is scooped into the front opening of the engine from the air during flight and is compressed by the speed of the jet; fuel is injected and buried, and the exhaust streams out the rear opening. As compared to rocket power, the ram jet has a great advantage in that it draws its oxygen from the air.
