Size and Number Dust (SAND) Detector

The Army is seeking a real-time engine intake dust detector for initial application as a part of the new designs currently in process for the A1 Abrams Engine Program. The desired dust detector system will measure particle concentrations and the size ofparticles to warn the driver when either the concentration level or size of particles detected is sufficient to potentially cause internal damage to the engine. To meet this need, POC is developing an innovative Number Dust (SAND) Detector based onacoustic wave scattering technology as a novel inline particle sensor capable of real-time monitoring of particle size and number distribution (concentration). The successful demonstration of the proof-of-concept in Phase I proved that the SAND Detectorconcept satisfies the Army's need. In Phase II we will optimize the SAND Detector design and fabricate an engineering prototype. The Phase II SAND Detector prototype will be tested under simulated test conditions for easy transition to Phase IIIcommercialization.POC believes that the SAND technology will add an important new safeguard to protect the $50 billion invested in new gas turbine engines each year. POC's unique SAND design will offer a compact, low-cost solution that will, for the firsttime, give the operator an alarm when particulate contamination is present, then characterize the contamination in terms of quality and size of particulates.
