Modeling the Detectability of Energetic Heliospheric Ions at Pluto During the New Horizons Flyby
Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.Abstract We investigate the detectability of heliospheric helium ions at energies up to 100 keV by the New Horizons (NH) spacecraft during its flyby through Pluto's induced magnetosphere. The Pluto Energetic Particle Spectrometer Science Investigation energetic ion detector observed a reduction in their flux by an order of magnitude as the spacecraft ...

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 5, Page 1656-1679, May 2026.ABSTRACT Metal additive manufacturing (AM) provides a pathway for creating highly optimized components that would be difficult to produce using traditional manufacturing methods. However, regardless of printing parameters or postprocessing, porosity remains a prevalent challenge in AM components because strain concentrates in the vicinity of the pore ...

Numerical simulation of ice growth on a MS-317 swept wing geometry [PDF]
An effort to develop a 3-D ice accretion modeling method was initiated. This first step towards creation of a complete aircraft icing simulation code builds on previously developed methods for calculating 3-D flow fields and particle trajectories ...

Nonlinear Analysis of a Two-Parachute System Undergoing Pendulum Motion [PDF]
Motion resembling that of a pendulum undergoing large-amplitude limit cycle oscillation was observed during a series of flight tests of an unoccupied Orion Capsule Parachute Assembly System (CPAS) comprised of two parachutes and a capsule payload.

Automatic computation of wing-fuselage intersection lines and fillet inserts with fixed-area constraint [PDF]
Procedures for automatic computation of wing-fuselage juncture geometry are described. These procedures begin with a geometry in wave-drag format. First, an intersection line is computed by extrapolating the wing to the fuselage.

Off-design correlation for losses due to part-span dampers on transonic rotors [PDF]
Experimental data from 10 transonic fan rotors were used to correlate losses created by part-span dampers located near the midchord position on the rotor blades.
