Jet is an airbreather, right?
Rocket makes its own oxygen?
JATO just became better known than RATO through wider usage.
It was ONA
that developed the JATO mod for the DC-9. It was a freighter. There do exist photos of them being fired. A good friend of mine has ridden a JATO takeoff at ONA
. The bottles did have a shelf life. All they were for was to help get the thing up through V2
with an engine out.
The total thrust was rather slight. It would take a lot of forward-firing rockets to have much effect on a 737 landing distance. Just not worthwhile.
your point is made by the Avco Lycoming engine. One version powers the BAe-146, a jet. One version powers the OV
-1 Mohawk, a turboprop. The third version powers the CH47 Chinook, a helicopter. Turbofan, turboprop, turboshaft - all in one engine.
To further muddy the jet-powered waters, lots of turboprops gain measurable thrust from the exhaust. The Convair 240/340/440 had augmentor tubes that aided engine cooling but they too produced measurable thrust. All that from piston engine exhaust and exhausted cooling air.
Happiness is not seeing another trite Ste. Maarten photo all week long.
