Chris Pocock write an article for AIN Online on September 8th 2016, talking about how Lord Corporation is providing a newly improved vibration control system of IVCS for the Boeing CH-47 Chinook helicopter. Completion of this program milestones under a contract that was rewarded by Boeing in late 2013.
Here is what Stuart Hartwell, the business development manager for Lord Global Aerospace & Defense says that
“The IVCS represents a major step in bringing significant weight savings to the H-47 platform.”
In order to measure aircraft vibration levels, the IVCS technology uses accelerometers. In addition to this there is a centralized computer that signals throughout a software algorithm in order to read data and send commands to force generators. The force generators are located under the seats of the pilot. In turn, these force generators will create an “anti vibration” that will then stop the progression of vibration. From these, this will create a comfortable vibration environment for the cabin.
There will also be a direct replacement or drop in replacement that can be used as a heavy passive turned vibration absorber. Here is was Pocock has mentioned that Mike Janowski stated.
“According to Mike Janowski, manager of electromechanical design at Lord, the IVCS is easily installed using existing mounts on the aircraft and outperforms the legacy system. It could be retrofitted to the MH-47Gs of U.S. Special Operations Command, as well as existing CH-47Fs and Chinooks that have been exported via the Foreign Military sales (FMS) process.”
