Assessing the Performance of Hypersonic Inlets by Applying a Heat Source with the Throttling Effect

Aerospace, 2022
Utilization of a heat source to regulate the shock wave–boundary layer interaction (SWBLI) of hypersonic inlets during throttling was computationally investigated. A plug was installed at the intake isolator’s exit, which caused throttling.

Analytical tuning of regulators in a cascade automatic discharge control system

Современная наука и инновации, 2023
When synthesizing automatic control systems, there is a problem with complex definition of controller parameters, and the main criterion becomes the achievement of stable operation, and the quality of the transient becomes of secondary importance.

Magnetars as cooling neutron stars with internal heating [PDF]

, 2006
We study thermal structure and evolution of magnetars as cooling neutron stars with a phenomenological heat source in a spherical internal layer. We explore the location of this layer as well as the heating rate that could explain high observable thermal
