I guess once you light the solid state fuel, you can’t modulate it for performance and just have to let it burn. I guess that’s how it works.
You guys are great. Hahaha.
The whole vehicle is the engine. The compression needed to make the jet work is achieved by the vehicles speed.
“How would this work? “
think “bottle rocket”
You need one moving part.
Sounds like a ramjet. Nothing new about that. Just need to pack it full of fuel to keep it going.
I’ve said this before, and some here don’t like it, but the rate of innovation in commercial aviation during the last 60 years have been pretty pathetic compared to the incredible innovation of the first 60 years (from the Wright brothers in 1903 to 1963). Sure commercial jets are safer, and there have been improvements in fuel efficiency and auto-pilot tech and a lot of that, but from the passenger side, it’s been very stagnant. I’m not flying to Europe any faster than I did 50 years ago. I get it that government regulations ( sonic-boom rules specifically) have limited what the aerospace companies can do. But, still, it’s been disappointing.
(flights from London to Sydney)
I gotta go from a’1984’ Tourist Trap
to a place where I can’t concealed carry?
Are there other, better choices?

Ramjets and Scramjets require the aircraft to be going supersonic speeds before they can even work.
So there has to be some separate way of getting them up to speed.
Just light the fuse and stand back.
I doubt it’s listed in the Bill of Materials, but the air passing through a forward inlet could be considered a moving part since it factors so heavily into the sustained dynamics of the engine’s operation. I’d think that a unit cost could be calculated reliably. $$$ per volume @ altitude x duration of combustion?
Ask Dyson. ;-)

If so here’s the stinker...
“...A ramjet is a variant of an air breathing jet engine that does not include a rotary compressor; rather, it uses the engine’s forward motion to compress the incoming air. A ramjet cannot function at zero airspeed and therefore cannot be used to power an aircraft in all phases of flight...”
The Nazi’s had similar in WWII with the V1, it had no rotating compressor components and was referred to as a pulsejet. The French had actual ramjet’s flying in the 50’s.
โNot only could it turn flights from London to Sydney into an afternoon jaunt instead of a 22-plus-hour ordeal,โฆโ
At one time and not very long ago that 22 hours would have been a jaunt.
What is an engine test that doesn’t really test the actual engine?
Our cat did that the other day with a Plastic Straw she found ,LOL
“I don’t get how they can develop an engine with no moving parts.”
Me either. How do you turn the fuel off?
Yes. All scramjets (supersonic combustion ramjets) have no moving parts. Once a plane is to speed, the wind pressure takes over and forces air through the scramjet where it is ignited and blasted out. Nothing moves.
See my book, “The Quest for the Orbital Jet,” in “The Hypersonic Revolution, volume III.
They mean a ramjet? 40s technology.
Its called a ramjet. The technology has been around a long time.
