On the subject of airfoil section development , can anyone shed any light on the story about the VR-8 ( well one of the Chinook Airfoil sections) being discovered by accident during icing trials?
There is an apocryphal story that it was noticed that after a certain time in the hover under the icing rig the Tq required to hover went DOWN noticeably.
This was found to be repeatable so the tests were conducted enough to map the new blade profile that the ice had formed before it melted off.
Anyone out there who "was that soldier"? its a super story and I like to think it has genuine roots
