Why didn't the Cessna 337 make it?

I have been thinking that it would be cool to refit an old 337 with
twin jet engines mounted in place of the rear engine with snorkles for
the intakes and a nose extension fairing in place of the front engine
for drag reduction and CG adjustment. Given the advances in small jet
engines in recent years, this might be feasible. Imagine the rate of
climb you would get. You could run the throttles at a modest setting
for cruise.

There is an experimental aircraft for you!

I'm waiting to see the real world numbers for the HondaJet - Plane and/or
engine.

Engine guys at Oshkosh said Honda was considering selling just the power
plant to others.

The Eclipse 500 will sell for about what a new Beech 58G
Baron will sell for, as soon as I win the lottery, I'll make
my deposit.

Actually, you would be implementing / developing an STC, not building a new
experimental aircraft... The rules are a bit stricter for that...

Knowing how flimsily Cessna tends to make their designs,
using the thinnest possible metals, etc, a re-engine job is
critical. Airplanes have speed and power limits, both for
structural strength and aerodynamics...the 337 is pretty
well at that point as sold by Cessna.

Hi Jim,

That is true, but if the jet engines were small enough they wouldn't
necessarily overpower the airframe. There are some really small
turbines out these days...

Dean

A jet needs to be faster to be efficient, the airframe is
not designed for Mach 0.60, let alone real jet speeds.
