Spacecraft entering a planetary atmosphere are surrounded by a plasma layer containing
high levels of ionization, due to the extreme temperatures in the shock layer. The high …

A new methodology to accurately and efficiently examine the radio frequency blackout
phenomenon during the hypersonic reentry process is introduced and validated. The current …

This paper presents numerical results in hypersonic aerothermodynamics, a critical field
within aerospace engineering, traditionally focusing on reentry capsules and more recently …

During the atmospheric entry phase at hypersonic speed, the radio communication from/to a
space vehicle can be disrupted due to the formation of a plasma sheath within the …

In view of the demand for high-energy and high-bandwidth signal detection in X-ray
communication (XCOM) during spacecraft reentry blackout, a detection module using fast …

numerical methodology to properly characterize and predict the communications blackout …

In hypersonic computational fluid dynamics, the two-temperature (2-T) model is widely used
to simulate thermochemical nonequilibrium. The 2-T model incorporates translational …

The radio blackout phenomenon poses a significant challenge during hypersonic spacecraft
re-entry, particularly due to its extended duration (several minutes). This study demonstrates …

At high hypersonic flight velocities, the accompanying intense kinetic energies increase the
temperature of the flow which in turn promotes chemical reactions that break up the air into …

Blackout emerges in the reentry phase of reusable launch vehicles (RLV). Therein, large
uncertainties exist in the telemetry signals of RLV, leading to potential safety problems. To …
