Algorithm for Determining Three Components of the Velocity Vector of Highly Maneuverable Aircraft

open access: yesComputation, 2023
We developed a signal processing algorithm to determine three components of the velocity vector of a highly maneuverable aircraft. We developed an equation of the distance from an aircraft to an underlying surface.

Estimation of the Induced Incidence of a High Reaction Axial Turbine Bucket

open access: yesEnergies, 2022
This paper describes the effect of the incidence angle of the bucket on the performance of the axial turbine stage. The off-design operating conditions of the turbine stage result in a change in the velocity diagrams.

Research on control strategy of vehicle stability based on dynamic stable region regression analysis

open access: yesFrontiers in Neurorobotics, 2023
The intervention time of stability control system is determined by stability judgment, which is the basis of vehicle stability control. According to the different working conditions of the vehicle, we construct the phase plane of the vehicle's sideslip ...

Bulk interactions and boundary dual of higher-spin-charged particles

open access: yesJournal of High Energy Physics, 2021
We consider higher-spin gravity in (Euclidean) AdS 4 , dual to a free vector model on the 3d boundary. In the bulk theory, we study the linearized version of the Didenko-Vasiliev black hole solution: a particle that couples to the gauge fields of all ...
