Are those doohickies that propel rockets called "engines" or "motors"?
Let's get every single rocketeer in the English-speaking world together at one launch, and have a big tug-of-war to settle it once and for all.
I try to refer to them as 'Motors'.. I feel Estes is wrong.
An engine is defined (loosely!) as a machine that make energy from mechanical means. the pistons pumping up & down to creat<script id="gpt-impl-0.5655488697115063" src="https://partner.googleadservices.com/gpt/pubads_impl_105.js"></script>e rotational motion & power, a steam engine doing pretty much the same work.. (has moving parts, that all work together to produce the desired work)
A motor is defined as a device that changes energies to produce power directly. An electric motor uses magnetic energy to produce rotational motion & power.. A chemical motor produces energy from a (controlled) chemical reaction..
I was really confused for a couple seconds until it finally clicked. I rarely run into B5 appreciators.
I prefer Catastrophic Take-off for CATO. Comes in motor, stability, and airframe flavors!
