Parametrisation of the orographic enhancement of precipitation and deposition in a long-term, long-range transport model [PDF]
Annales Geophysicae, 2000 Orographic enhancement of wet deposition arising from the 'seeder-feeder' effect is, by necessity, highly parametrised in long-range transport models of acid deposition that are long-term (i.e.

Acoustic and propulsion performance facility [PDF]
The Journal of the Acoustical Society of America, 1974 A unique facility has been developed at the Lockheed-Georgia Company to evaluate, simultaneously, acoustic and propulsion performance characteristics of lift augmentation systems of the type considered for V/STOL aircraft. The facility is ideally suited for concept parametric and systematic noise-reduction investigations where the relationship between ...

Comparison of Aero-Propulsive Performance Predictions for Distributed Propulsion Configurations [PDF]
55th AIAA Aerospace Sciences Meeting, 2017 NASA's X-57 "Maxwell" flight demonstrator incorporates distributed electric propulsion technologies in a design that will achieve a significant reduction in energy used in cruise flight. A substantial portion of these energy savings come from beneficial aerodynamic-propulsion interaction.
