Editing Ramjet (section)

====René Lorin====
The ramjet was designed in 1913 by French inventor [[René Lorin]], who was granted a patent (FR290356) for his device. He could not test his invention due to the unavailability of adequate equipment since there was no way at the time for an aircraft to go fast enough for a ramjet to function properly.<ref>{{cite book |last=Zucker |first=Robert D. |author2=Oscar Biblarz |title=Fundamentals of gas dynamics |publisher=John Wiley and Sons |year=2002 |isbn=0-471-05967-6}}</ref> His patent showed a piston internal combustion engine with added 'trumpets' as exhaust nozzles, expressing the idea that the exhaust from internal combustion engines could be directed into nozzles to create jet propulsion.<ref>[http://www.flightglobal.com/pdfarchive/view/1941/1941%20-%202218.html 1941 ''Flight'' article] explaining ramjets and mentioning Lorin's work</ref><ref>[http://www.nps.gov/nr/travel/aviation/usn.htm "Aviation: From Sand Dunes to Sonic Booms: A National Register of Historic Places Travel Itinerary," National Park Service web site]</ref><ref name=lorin>{{cite web |title=Lorin Ramjet |website=enginehistory.org |url=https://www.enginehistory.org/Rockets/LorinRamjet/LorinRamjet.shtml}}</ref>
