- Chrysler actually tried this in the early 1960's. The gas turbine engine
- (that's what a turboprop is) was front mounted and featured a type of
- recuperator in the cycle. It consisted of a rotating wheel thru which
- exhaust would passed, heating the wheel. The other part of its rotation
- was in the high-pressure stream.
-
- Apparently, there were many practical propblems with make this type
- of engine impractical for passenger car transportation - cost of material
- for the blades etc (titanium), hot exhaust, and susceptibility to damage
- by debris in the exhaust. Foreign object damage (FOD) is a major concern
- at airports, for that reason.
-
- However, I have no doubt that some new technology may change things.
- Already, turbocharged engines are featured in many cars. These integrate
- an element of gas turbine propulsion into a reciprocating engine (compressor
- driven by exhaust gas).
