My take on the dissertation is that air
 bleed like used on turbine
 engines is used to control boost
 pressure. One problem I can see with
 that is possible overspeed of the
 turbine which could have catastrophic
 results. Using a wastegate and putting
 that back into the exhaust going
 through an axial flow power recovery
 turbine makes more sense to me.

 Hi, it is a turbocharged intercooler
 system for conventional turbocharged
 engines. It is not intended for rotary
 charge cooling but might be useful
 for that.  The turbocoolers
 turbine is powered by boosted intake air which
 drops in pressure and temperature going
 through it.  They claim sub ambient
 temp air to the intake manifold.

 Paul,
I think the aircycle system is similar to Aircraft air conditioning systems.
They cool the hot compressed gas with intercoolers and then re-release it for cooling.
Attached is an example.  Notice that they even use the condensation to spray across the coils for added efficiency.
This system will spit snow and ice if not properly balanced.

Lowering the intake air below 150 F has little benefit.
The cost and additional weight would not be worth it.
An intercooler will do that particularly with a water spray.

With a rotary we can get all the HP we want.
