ramen noodles,
There is no questioning the intelligence of Jayant Sirohi.
However, his primary field appears to be ornithopters, mechanisms for controlled actuation, and micro aircraft (MAV). He has one patent entitled 'Biomimetic mechanism for micro aircraft' and he has a patent pending entitled 'Fluid-Driven Artificial Muscles as Mechanisms for Controlled Actuation'.
None of the above has anything to do with the three primary claims, which were mentioned in the first post on this thread.
After the University of Maryland he worked for Sikorsky for a short period of time and then left for the University of Texas in the Fall of 2008.
Ironically, while at the University of Maryland, Dr. Sirohi co-presented a paper to the AHS entitled
"Design and Testing of a Rotary Wing MAV with an Active Structure for Stability and Control". A picture of the MAV shows that the motor and the driven rotor have a common axis of rotation. The paper was presented 2-1/2 years before this patent application and this, in and of itself, should negate the first claim in this patent application.
The lack of any substance in the application suggests that the source may not be the named inventors, or even an engineering department.
Perhaps other major rotorcraft companies should be made aware of the future ramifications of such a patent, if it was to be approved.
