Aviation research, sourced & cited.
Curated index of aviation-relevant research from NASA NTRS, NTSB safety studies, FAA CAMI, and academic sources. Every record links back to its original — we don't host PDFs, we describe each paper and credit the authors. Built for cross-link with the rest of Atlas: search by topic, drill into a CFR section or airframe and see the research that bears on it.

International Space Station Bipropellant Plume Contamination Model update for short thruster pulse widths
The International Space Station (ISS) Bipropellant Plume Contamination Model has been a vital tool for characterizing the thruster plume-induced contamination environment at the ISS but was not intended to be used for ve…

Particulate Emissions Hazards Associated with Fueling Heat Engines
All hydrocarbon- (HC-) fueled heat engine exhaust (tailpipe) emissions (<10 to 140 nm) contribute as health hazards, including emissions from transportation vehicles (e.g., aircraft) and other HC-fueled power systems.

MEA Failure Mechanisms in PEM Fuel Cells Operated on Hydrogen and Oxygen
Polymer electrolyte membrane (PEM) fuel cells are candidates to replace alkaline fuel cells for space power programs. Broad power ranges, high peak to nominal power ratio, and low maintenance costs are the major advantag…
