GENERAL LASERTRONICS CORPORATION — Department of Defense SBIR Phase I: ABSTRACT: The proposed portable, hand held, laser tool will enable efficient field mainte

Description

ABSTRACT: The proposed portable, hand held, laser tool will enable efficient field maintenance of specialty coatings and outer mold line (OML) materials of advanced aircraft. Laser pulses are scanned over the surface with optimal power, energy, and control to remove coatings without substrate damage. In Phase I, the contractor will demonstrate automated closed loop removal. The laser produces 10,000 pulses per second, and optics in the tool move the laser pulses to avoid dwell on one spot. The operator selects surface colors to remove. Between pulses, sensors interrogate the surface and electronics decide if the laser should fire. The proposed tool concept includes guides to position the tool for cleaning OML materials and for tapering coating layers. Automation of the guide system in future systems could enable"set-and-forget"operation. The proposed tool also includes integrated waste collection to eliminate hazardous emissions. Work area cleanup requirements are eliminated, and concurrent maintenance can occur elsewhere on the aircraft. Aircraft maintenance time is substantially reduced. The proposed laser is commercially available, and the laser delivery subsystem has demonstrated technology readiness level of 9. The project will focus on tool development and operational approval for the specific objectives of this topic. BENEFIT: Higher level of weapons system readiness. Reduced environmental impact. Reduced health-risk and injury potential of maintenance personnel
