From the ever-authoritative Wikipedia:

A jet engine is a reaction engine that discharges a fast
moving jet which generates thrust by jet propulsion in
accordance with Newton's laws of motion. This broad
definition of jet engines includes turbojets, turbofans,
rockets, ramjets, and pulse jets. In general, most jet
engines are internal combustion engines[1] but non-
combusting forms also exist.

In common parlance, the term jet engine loosely refers
to an internal combustion airbreathing jet engine (a
duct engine). These typically consist of an engine with
a rotary (rotating) air compressor powered by a turbine
("Brayton cycle"), with the leftover power providing
thrust via a propelling nozzle...

So, yeah, in the strict technical sense you are correct: Any reaction
motor that discharges a jet of exhaust can be called a jet. But I'm
going to claim the broad low ground of "common parlance."

Anyhow, your winch project with Bob Korves is looking good!

Let me know if you need some occasional welding or fabrication. If
you've got one Bob K. on your project, two is going to be better,
right?

Thanks, (the other) Bob K.

As late as the mid-60s, it was still common parlance to refer to
"turbojet" engines, to distinguish them from other forms of jet
propulsion (thus cleverly revealing that I'm old enough to remember).
As a completely random aside, for those who might be interested in a
key but now nearly forgotten figure in the history of both Jet
Propulsion Labs and Aerojet, look up Jack Parsons in your favorite
search engine. He was the quintessential "rocket scientist"...

We've hit that point where we're 90% done, and the remaining 10% is
taking as long as the rest. Thanks for the offer!

Can this one be aero-towed or winch launched? Getting the fuel for the small rocket engine might become a problem. That stuff was said to have some nasty habits like catching fire when it comes in contact with certain materials and being extremely corrosive.

Alexander Lippisch (the Me163's designer): "If you put in your
finger, you get back only the bone". I don't remember whether the
fuel or the oxidizer was worse.

i think i saw something online that the US acquired a few after the
war and towed them with B-29's while test pilots checked them out.
Perhaps we need to notify the Commemorative Air Force and see if they
will put a towhook on Fifi!

That's obviously the unpowered replica.

Nearly a year ago I visited RAF Cosford on a wet day during a CGC
gliding expedition to The Mynd. Cosford which has a fantastic collection
of Cold War British aircraft including all the V-bombers as well as a
wonderful collection of late 60s British experimental jets and a
selection of WW2 aircraft including a Me-163B. I was intrigued to see it
has a tow hook in exactly the same place as that replica and wonder why.
Was it for aero-towed retrieves if it had to land out after a combat
sortie and/or for moving them between airfields?

The 163 used 100% peroxide as the oxidizer. Nasty stuff that would
"burn" anything it could come in contact with.

F-16 doesn't glide any better than a lawn dart.

F-15 glides beautifully. I once rode in one that glided 75 miles from
flight level 400, in flight idle, joker fuel, to pattern altitude
without touching the throttle.

Here's an excellent video with lots of detailed shots. Tost hook is
clearly shown. Also, I'd never noticed the split flaps / drag devices
which are deployed in this video. Revolutionaly airplane in many aspects.
