"The culprit was a faulty swashplate actuator pressure switch, which has been traced back to a manufacturing error by supplier Eaton Aerospace, according to ITN.
A V-22 has six swashplate actuators with two pressure switches each. The swashplate is a device that allows the pilot to control the movements of the rotors. "
Looks like the processes necessary to control the actions of a swashplate actuator can be complicated. I wonder how Torvec is coming with the controllers for the IVT swashplate.
Has anyone heard of any update on that? I heard that it was production ready, but I was wondering if that is still being tweaked.
National defense funding project sent to the Senate...
"$3.5 million for the development of a digital hydraulic hybrid system. The goal of this project is to develop a series hybrid hydraulic system that achieves significant weight and volume reduction while also gaining a 50 percent improvement in fuel efficiency over current technology. It is intended that the hybrid hydraulic system resulting from this research will be demonstrated on a High Mobility Multipurpose Wheeled Vehicle (HMMWV)."
"$3 million for hydraulic hybrid vehicle technology. This research seeks to produce a new line of advanced, highly efficient, hydraulic pump and motor products which will replace the conventional automatic transmission and could significantly improve overall drivetrain efficiency in military ground vehicles."
