Hello Boydouse's members

Some refreshing news in the world of Stirling's engines...

SYCOMOREEN is a french family company which works on a whole range of inventions and focuses on renewable energies.

Her last baby is just born :razz: :
Stirling with Rotary Annular Trilobic Pistons

adapted by Remundo from the original Pascal HA PHAM's engine.

You can also see the dedicated web page
and Pascal HA PHAM's website


We are waiting your reactions on this new Stirling's engine with general purpose: thermal powering (cold or hot), mechanical, electrical power, cogeneration, thermolysis, hydrolysis for various products(hydrogen, metals...) from clean and/or waste energies like organic rejected materials, torched natural gas, sun's concentrated radiance, etc...

At this time, we develop our own engines, but we are open to any proposal of industrial partnership

Hello Boydouse members,

What about SPRATL and trilobic engines ?

Hello Stirling's Fans,

Perhaps do you enjoy wind too ? Renewable Energies in general ?

If it is the case, see our notices about ROBIPLAN Wind turbine of Pascal HA PHAM, and another amazing concept on SYCOMOREEN, the naturally energetic movement.

Best regards and see you soon ! :smile:

Hi the Stirling's fans !

I'm sure you enjoy new designs of engines and, altough you may prefer Stirling, you also enjoy quite Internal Combustion Engines. Isn't it ? :razz:

I have what you need to relax yourselves : the Octogonal Piston with Controlled Deformable Geometry (POGDC)

Best Regards from France :grin:

Hi the Stirling Men,

Here is a video about MPRBC (rotary pistons machine with controlled beating), not basically a Stirling (initially designed for internal combustion), but it could be adapted for Stirling cycles.

And nevertheless, the clip is quite interesting ; it's indeed the first 3D video of the engine...

You will discover in our "renewable energy production" activity the photovoltaic farm over since one week.

For our engineering works, the anti-erosion epicyclic rotary valve (SAERE) is notably unveiled.

And we keep to think about our SPRATL, but shuuuutt... :razz:

Good reading and see you soon !

Hi the Stirling men and Women,

Today, I'm pleased to show you a little poster which summarizes the technical points to use SAERE on conventionnal machines with cylinders.

Surely a nice valve for high pressure Stirling's application like the Ericsson engines.

See you soon ! 8)

Hi The Stirling's Fans,

A resuming article on the French "Anti-Friction rotary epicyclic valve" (SAERE) has been published on the Invention-Europe Portal.

For those who were looking for an easy approach of SAERE, that is the opportunity to find one. :razz:

More information and many other amazing concepts : http://sycomoreen.free.fr

Bye !

Hi the Stirling Fan's

In France, our MPRBC makes one's life... First prototypes have been assemblied...

On the wall in a way...

and the reverse way.

Happy Christmas ! :cool:

Hi the Friends,

Unveiled views and amazing motions ?

Sycomoreen offers you a full immersion through the MPRBC's kinematics

Enjoy, and read you soon :cool:

Hi the Stirling's fans,

News about the SYCOMOREEN's Stirling

Some recall
Image
The Stirling Engines with Rotary annular TriLobic Pistons TriLobiques (SPRATL) are coming from the adaptation by SYCOMOREEN of the original machines trilobiques RPATL trilobic machines by Pascal HA PHAM

The design of the SPRATL has especially worked to reduce or suppress all the drawbacks currently known about the Stirling engines, notably:
1) Defect of volumetrie for the Vmin and the Vmax
2) No respect of the cold and hot isothermal changes
3) Bad caloric regeneration of the working fluid through the 2 isochoric changes
4) Spontaneous thermal flows from the hot parts towards the cold parts inside the engine and without to make the fluid work.
Image

The point 1 is totally deleted

Le point 2 is strongly optimized by big outflows inside the cold and hot engines

The point 3 is widely improved by a thermal exchanger with opposite and continuous outflow of fluid

The point 4 is managed by the nearly complete separation between the hot parts and the cold parts in the engines as showed below:
Image

All these improvements will allow to go nearly the ultimate thermodynamical Carnot's efficiencies, for the motors and also for the heating pumps and the refrigerators

The News
Firstly we're preparing the build of a prototype, but it is a little too early to speak about it now

But there is much more interessant Pascal HA PHAM and Yves SAUGET work in narrow collaboration on the spherical ZZ machines (see notices of 01/01/2010 and 11/12/2009, and weave some ties with another inventor of spherical engines, Shi Zhe and his Fuhandaïgu machine..

The first sketches and thoughts let foresee some adaptations in Stirling of these spherical machines with the same qualities of the SPRATL's design

Perhaps will Pascal HA PHAM write you soon some words... Bye ! :cool:

Hi,
I am pascal HA PHAM and i hope to be technicla friend on your forum...
but...my english is not easy...hum just !

to have the basic cinématic for a STRILING engine in ZZ fraisoïdal concept ?

two engine (cold and hot) with two volumètrics step/level (up level and down level)each one have a different "volume"

thèses engines like that :

Pascal HA PHAM
SHI ZHE ?

And a spécial new aréa of FRAISOIDALES engine (ZZp à FF)

yes !

Have a great day.

Hello the Stirling's fans,

Why does SAERE achieve a variable valve timing with an epicyclic gearing ?

Here is the short and illustrated in the SAERE's FAQ which has just been updated.

You're friendly invited to discover or see again our Anti Friction epicyclic rotary valve from France

Bye ! :cool:
