Quick Summary
The National Aeronautics and Space Administration (NASA), specifically the NASA Shared Services Center (NSSC), has issued a Special Notice indicating its intent to award a sole source contract to SCIENCE ENGINEERING ASSOCIATES, INC. for the Purchase of Optical Array Probe 1D2DX. This probe is crucial for calibrating the Icing Research Tunnel (IRT) at NASA Glenn Research Center. Interested organizations may submit capabilities by May 26, 2026, to challenge the sole source determination.
Scope of Work
The requirement is for an Optical Array Probe (OAP-1D2DX) capable of measuring droplet sizes from 15 µm to at least 450 µm, providing both 1D histogram and 2D image data streams. This probe will replace an aging OAP-230X and must:
- Interface with the existing SEA M300 Data Acquisition System.
- Include deice capabilities with a full heat front dome.
- Be cleaned, aligned, and calibrated.
- Be shipped to NASA, with training/guidance provided on the new interface.
Deliverables
One SEA 1D2DX Probe system, including a spinning disk, 220VAC instrument & deice power, sapphire window modification, pigtail interface, shipping/storage case, new canister with fully heated dome, and calibration specifications.
