Technologies

MetroLaser has developed a Computational Fluid Dynamics (CFD) based simulation tool to estimate the aerodynamic effects of variable surface roughness, such as from surface abrasion of helicopter rotor blades and the protective coatings that are applied to counteract it. 

MetroLaser has developed a computational aero-optics test simulator (AOTS) code that models and simulates aero-optical effects on light propagating through an aerodynamic flow field.

ASSURES is an Authentication Technology to identify rogue components (flawed, defective, counterfeit, substandard manufacturing) in additively manufactured parts.

MetroLaser has developed Digital Holographic Technology (DHT) for characterizing the size and shape of particles from about 10 μm to over 1,000 μm.

Filtered Rayleigh scattering (FRS) is a technique for measuring gas flow properties, such as velocity, temperature, and/or pressure, that does not require seeding of the flow.

MetroLaser has developed a high frequency, digital photonic, two-dimensional wavefront sensor system for flow diagnostics and aero optics.

Filtered Rayleigh scattering (FRS) is a technique for measuring gas flow properties, such as velocity, temperature, and/or pressure, that does not require seeding of the flow.

Filtered Rayleigh scattering (FRS) is a useful and proven tool for flow diagnostics, and a key aspect of this technique is that no seeding of the flow is needed.

When monitoring the performance of jet engines, aerospace engineers typically are concerned with intake phenomena, such as how wind velocity, rain and shock waves affect the turbine at subsonic to supersonic speeds. 

MetroLaser has demonstrated a system to perform nondestructive inspection (NDI) of a variety of critical parts ranging from small turbine blades to large sections of the wing or fuselage.

Molten sand and ash may deposit on turbine blades and other hot section components of gas turbine engines, forming a glassy material composed mainly of calcium magnesium alumino-silicates (CMAS) that can cause damage.

Under an SBIR program from the Army Research Office MetroLaser developed a technique to measure the size distribution of droplets in a plane.

Planar Doppler Velocimtery (PDV) is capable of measuring instantaneous, three-dimensional velocity vectors of moving particles or solid material in a laser light sheet everywhere in the field of view.

MetroLaser has developed a diagnostic system for accurate temperature measurements on the surface of a rotating turbine blade in an operating engine using laser-induced excitation of thermographic phosphor coatings on the blades.
