Utilization of Exhaust Gas of Aircraft Engines 460259

THIS paper-relates to the recovery of energy from the exhaust gas of aircraft reciprocating engines by means of the exhaust jet, the steady-flow turbine, and the blowdown turbine.
The performance of a reciprocating engine compounded with these energy-recovery devices is discussed in detail.
The operating conditions for maximum performance are presented, and the effects of engine cooling and knock limit on these conditions are considered.
A comparison is made of the overall weight of the engine plus fuel for the various exhaust energy-recovery systems at several operating conditions and durations.
