\The

study assessed the
capability of the free-piston
Stirling
engine (FPSE) to meet
requirements for military
mobile electric
ground power. Operational
requirement parameters
included physical,

that, with continued
development, the FPSE can
meet or exceed all
of the military requirements
for 3 kW silent tactical

SUMMARY
Free-piston
Stirling engines (FPSE) are advanced conversion power syytems
that operate with two moving parts to produce electrical power from most
any fuel source,
with high efficiency and high reliability. Mechanical
Technology Incorporated (MTI) is developing the FPSE
for stationary com-
mercial applications in the size range below
10
kW. Because of the
poten-
tial strategic
and logistics advantages offered by these machines, the
U.S. Army Mobility Equipment Development
Command has contracted MTI to
project the capability of the FPSE to meet requirements for military ground
power. This report documents the results of that study.
The methodology employed in this study
involves the comparison of test
.
documents.
Because the current development is oriented toward commercial
applications, engineering projections were made to evaluate the feasibility
of adapting the FPSE for
military use.
Operational requirement parameters were divided into six categories:
physical. thermodynamic, audio, material, operational,
and electrical.
The results of
the ensuing parametric assessment are summarized in the
table that follows.

data and design calculations
with military requirements and standard
Of the six categories assessed, only the physical requirement for low
system weight would demand additional technological development for FPSEs
t
to have the capability for complying with military specifications.
In
all
othitr
regards, the FPSE was found to have the capability
for meeting
or exceeding the requirements. Further,
when comparing the projected
militarized FPSE generator system with alternative geaqrators from the
existing standard family, the FPSE was determined to be potentially
superior
in all aspects.
The specific conclusions that were drawn from the study are stated as
follows:
*
The state of the art of FPSEs allows for current
commercial
hardware designs to achieve a significant
portion
or
the military requirements and standards.
• Engineering projections show that, in the
near term,
the FPSE can be developed to comply with all
military requirements for ground power.
e
Present FPSE hardware designs compare most favorably
with alternative generator sets now in the standard
family.
•Adv&nced FPSEs will surpass the operational
characteristics
of alternative standard family
generator sets
ir
All
respects.
a
The onerational and developmental testing of a FPSE
generator operating with military logistic! fuel
capability could be established
by 1984.
*
A system development program needs to be implemented
in order to adapt commercially oriented FPSF technology
for military application.
