The main items of equipment used in the experimental tests were: a 30 kW Capstone microturbine, a compact heat recuperator
, a hot water tank, a 10 TR absorption chiller, a chilled water tank, a cooling tower, and a water pumping system for the water circuits.
The fundamental technology for development of the more advanced 200 shp class turbine engine that RASPS will develop over the next 5 years has been demonstrated in UAVT's UTP50R propulsion system, a 50 hp class turbine engine with a recuperator
, high-speed gearbox, variable-pitch propeller, and Full Authority Digital Engine Control (FADEC).
The high-temperature low pressure s-C[O.sub.2] enters the recuperator
to heat the s-C[O.sub.2] to required inlet temperature for the reactor at the high pressure side.
An additional high pressure C[O.sub.2] split flow extracted from LTR outlet to the economizer (ECO) can not only utilize flue gas heat but also increase high temperature recuperator
(HTR) effectiveness, which is a valid method employed by aforementioned studies.
The McIntosh plant could achieve considerably higher efficiency over Huntorf plant using a recuperator
to reduce exergy loss.
2-3 Constant pressure heat transfer in a recuperator
, recovering exhaust heat.
Destruction exergy in the recuperator
is written as follow:
Complete unlocking takes place after 21mm of travel, at which time a spring-loaded plunger (called the barrel recuperator
spring assembly) on the interior of the receiver body on the left side returns the barrel to its forward position and the empty case is extracted.

[m.sub.l] represents the canon muzzle and it suffers the shock force [F.sub.C] and recoil resistance R in the axis direction; recoil resistance R includes recuperator
force [F.sub.FJ], recoil brake force [F.sub.ZT], and constant friction [F.sub.[phi]].
In this design, another heat exchanger (recuperator
) is added before the evaporator, using the steam from the expander to preheat the working fluid.
