I first proposed this engine (in raw schematic form) in response to Mike's assertion that a Reynst-breathing engine and a Lockwood are basically the same thing, taking the front-end reflector into account:
Here is his very interesting original discussion of this subject:
Even the traditional Reynst Pot obeys the Hinote Criteria (L/3, L/5 and L/8 critical points), if you hold your mouth right when you look at it:
But specifically, the only things that make this more like a Lockwood than anything else all derive from the fine points in the details:
- This engine has the uniformly tapered tail cone
- The tail cone inlet (front end) area is very small
- The intake area is very large
- The intake area tapers from full size at the chamber to smaller at the throat of the flare
- There is significant chamber nozzling out through the intake
- Kadenacy breathing action will be dominated by the intake
- Intake velocities and massflows will be relatively high
- Tailpipe velocity will be quite low, though massflows will be fairly high
- Much of the tailpipe air mass will be more-or-less stalled in the cone for a significant part of the cycle
- A very large fraction of total developed thrust will be from the intake
Some of these traits will be similar to a Chinese; some not. Some will be like the FWE, some not. Some like a Reynst Pot; some not. It is only the flows that are essentially modified by the geometric details. The acoustics are practically the same.
Optically, there is almost no difference between a 40-foot long room and a 20-foot long room with a mirror for one of its end walls. It's when you design the air conditioning that you'd see the difference.
