FORD FREE-PISTON ENGINE DEVELOPMENT

SAE Technical Paper Series, 1959
<div class="section abstract"><div class="htmlview paragraph">THE Free-Piston Engine Program described in this paper was concerned with determining thermodynamic relationships of small, high-speed engines. The purpose was to establish proper engine geometry and mechanical design which could then be applied to developing larger automotive ...

Large Free-Piston Stirling Engines

1985
The word ‘large’ applied to Stirling engines means different things to different people. An engine having a 3 kW output would be large to those working on artificial hearts or cryocoolers for electronic applications. It would be small, negligibly so, to those interested in locomotive propulsion.

A two-stage free-piston driver

Shock Waves, 1999
The overall cost of free-piston driven facilities can be substantially reduced if the contraction between the compression and shock tubes is replaced with a constant area section. However, with such an implementation, a new driver concept is required in order to achieve a realistic facility length. This paper describes a new free-piston driver type for

The Free-Piston Shock Tube

Aeronautical Quarterly, 1966
SummaryA study of shock tube operation with free-piston compression of the driver gas is presented. It is shown theoretically and experimentally that shock Mach numbers exceeding 30 in air may be obtained with an apparatus of moderate size. The operating limitations imposed by the maximum pressures allowed in the apparatus, by the ratio of the volume ...

Recent developments with free piston drivers

AIP Conference Proceedings, 1990
The history of free piston drivers is reviewed and the free piston facilities established at the Australian National University in the late 1960’s are described, with mention of the sustained and fruitful tradition of research which has been maintained in these facilities.

SUPERCHARGING in the FREE-PISTON CYCLE

SAE Technical Paper Series, 1959
<div class="section abstract"><div class="htmlview paragraph">THE RESULTS of analytical studies backed by actual tests concerning the use of supercharging in the free-piston cycle are reviewed. They indicate that, under conditions of increased cycle pressure ratio and of adequate cooling of the air, supercharging has power possibilities far

Free-piston Space Stirling Technology Program

Proceedings of the 25th Intersociety Energy Conversion Engineering Conference, 2005
MTI was awarded a competitive multi-year contract in August 1988 by NASA for the development of the free-piston Stirling power converter technologies required for space and a demonstration of the technology in a prototype Space Stirling power converter. Free-piston Stirling power converters have the potential to provide high reliability, Long Life, and

Design of Free-Piston Linear Generator

2020
Hydrocarbon fuels have high energy density compared to batteries (reference); hence, converting the energy of fuels through conventional engines into electrical energy with the help of rotary generators is a common practice. But this process involved lot of inefficiencies. Coupling of two new concepts, i.e.

Modelling of a free piston problem

2006
We give a qualitative analysis of the free boundary value problem which models the motion of a piston. A basic role is played by a third-order operator, whose properties are used for solving preliminary problems. The differential equations are transformed into a nonlinear Volterra system, which is dealt with by the fixed point theorem.
