Just dug this up .....print is small in the side-by-side, so I opened them as single pages so this short piece might be made more legible. , Kevin

I came across this NACA photo of a ramjet missile. It could be a Burner Test Vehicle, but I can't find anything online that confirms what it actually is. Anyone know?

"16-Inch Diameter Ramjet Prepared for Flight Test
A NACA researcher prepares a 16-inch diameter and 16-foot long ramjet for a launch over Wallops Island in July 1947. The Lewis Flight Propulsion Laboratory conducted a wide variety of studies on ramjets in the 1940s and 1960s to determine the basic operational data necessary to design missiles. Although wind tunnel and test stand investigations were important first steps in determining these factors, actual flight tests were required. Lewis possessed several aircraft for the ramjet studies, including North American F-82 Mustangs, a Northrup P-61 Black Widow, and a Boeing B-29 Superfortress, which was used for this particular ramjet. This was Lewis’ first flight at over the experimental testing ground at Wallops Island. The NACA’s Langley laboratory established the station on the Virginia coast in 1945 to conduct early missile tests. This ramjet-powered missile was affixed underneath the B-29’s left wing and flown up to 29,000 feet. The ramjet was ignited as the aircraft reached Mach 0.5 and released. The flight went well, but a problem with the data recording prevented a successful mission. Nonetheless additional flights in November 1947 provided researchers with data on the engine’s combustion efficiency at different levels of fuel-air ratios, thrust coefficients, temperatures, and drag. Transonic flight data such as the rapid acceleration through varying flight conditions could not be easily captured in wind tunnels."

Google image search. Took less than a minute. (Very handy tool.)

Thanks for that. I figured it was something at Wallops Island but didn't have specific details.

I saw photos of these ramjets on the tips of F-80 Shooting Stars whenever I read articles on American ramjet development during the 1950's .....
 
Is Marquardt still an extant corporation or has it gone bust or been acquired?
 
Some of the last chapters are empty, but the first part is still interesting. So I collected the entire history in a single pdf file. If a moderator thinks I broke some IP or something similar, please delete this post and the attached file.
