While the terms can change over time, my understanding in ME circles is that "engine" is usually referring something that converts a source of energy into a force. So in this case, a device is using chemical energy (LOX + kerosene) into thrush (5kN) so it would meet the definition of an "engine."
- dotancohen 2y agoErr... almost. An engine is something that has significant engineering effort put into it, you can see that the words are cognate. A motor is (usually an engine) that converts potential (stored) energy into motion, by way of some force. I do believe that motor and motion are also cognate. But outside the etymologies, there is no standard, agreed upon definition for either the term engine nor motor. I personally like these etymology-based definitions (otherwise how do you excuse the term "siege engine") but it's not a hill I'd die on.
