Pascal HA PHAM was
asking SYCOMOREEN a few time after his discoveries about the ROBIPLAN
®
to achieve
scientific studies.
There works and
researches have focused on the the main following axes :
1) To set a State of the Art of the windturbines technologies and to
theorically estimate the yield of a ROBIPLAN ® wind turbine
2) To propose ROBIPLAN's ® cinematics which benefit from all
the swept surface by the ROBIPLAN's ® blades
3) Theory of the kinetic limit of vehicles moving while facing the wind
and with the only power of the wind
1) State of the
art about wind technologies and yield[
February 9th, 2009]
This scientific survey
put
in place the ROBIPLAN's ® technology in comparison to existing
devices and developped a
mathematical outstanding model to estimate the theoretical yield of
this new type of wind turbine,
classically defined as the ratio between the power given by the blades
to the flow of kinetic power on the turbine.
1) The
BIROBIPLAN's kinematics [
June 30th, 2009]
Pascal HA PHAM,
inventor of the original concept about ROBIPLAN's ®
windturbine, and also the scientific study of Februar 2009 achieved by
SYCOMOREEN
have put to the light
a
promising possibility to use 2 contra rotary ROBIPLAN ®
windturbines contrarotatives, and place one after the
other in the direction of the flow of the fluid.
This special organization is
called BIROBI, or BIROBIPLAN.

3) Theory
of the kinetic limit of vehicles facing the wind and moving with the
only power of wind
3.b) [
May
29th,
2009] Then
the
definition of the purely theoretical issue : is it possible to move
while facing the wind with a wind turbine ? If yes, what is the
theoretical maximum ratio of the windspeed that one can reach while
neglecting all the drags of the vehicle (except the drag of the wind
turbine) ?
Sycomoreen is answering YES with a theoretical
maximal limit of 80% of the absolute speed of the facing wind (while
using the Betz's
limit). The ROBIPLAN ®
wind turbine of Pascal
HA PHAM, of MONOROBI type, are reaching 25%, and the BIROBI type is
better with 66% ; the classical tri-blade windturbines are
reaching 56%.
To see the
scientific notice which give the detailed hypotheses.
