Apparatus And Method To Test Abrasion Resistance Of Material Using Airborne Particulate (Blown Sand Abrader - BSA)

The US Army NSRDEC seeks to commercialize through patent licensing, US Patent No. 7,347,768, Issued: March 25, 2008; Apparatus and Method to Test Abrasion Resistance of Material Using Airborne Particulate.
Abstract: 
In one embodiment, the apparatus comprises a conduit network, a primary air stream generating device to generate a primary air stream in the conduit network, a secondary air stream generating device to produce a secondary air stream in the conduit network, and a particulate handling device to deposit particulate into the conduit network so that the particulate enters the secondary air stream. The conduit network merges the secondary air stream into the primary air stream to allow the particulate to enter the primary air stream, and allow the primary air stream to blow the particulate at a test sample positioned within the conduit network.
