Why are multiple engines different?

The reason we use jet engines is that they are inherently more powerful
and they can operate at high altitudes where the efficiency penalty
compared to piston engines is less. At high speeds, drag is a more
important factor in fuel economy than engine efficiency, so jet
airliners get their best fuel economy at high altitude. But for short
hauls where it would just be a waste of fuel to climb to high altitude
and descend again, a turboprop will deliver more power than a piston
engine with greater fuel economy than a jet.

There are still the questions of simplicity and reliability, which I
thought were both higher for gas turbines. They are certainly more
reliable; and I should think they'd be simpler, too.



Turbine engines cost a lot. I know a guy who bought a Bell 206 and shortly
after burned up the engine during start-up. That little booboo cost him in
the neighborhood of $80,000.

Sounds painful. How much does the entire helicopter cost, though?

Over half a million for a 25 year old one.

So it's like spending $15,000 for a car and then having to replace the
engine for $2400. That's not so bad, relatively speaking.

How much does it cost to replace a piston engine in a single-engine
aircraft?

Add the words "about a month after you bought it" and you'd be about right.

One time some years ago when my Warrior was in the shop for an annual,
one of the A&Ps pointed to a nearby 206 and told me with a smile, "We
just did a hot section inspection on that helicopter that cost
$70,000." I thought that was significant at the time since it was 3
times what my Warrior was worth.

Sounds like it didn't pass the inspection.
