Flight Speed Evaluation Using a Special Multi-Element High-Speed Temperature Probe

open access: yesAerospace, 2022
In the context of aircraft aerodynamics, the compressibility of air flowing around the aircraft must always be considered. This fact brings with it one inconvenience: to evaluate the velocity of the flowing air (airspeed), it is necessary to know its ...

Analysis and Recovery of Aircraft Deep-Stall Phenomena Using Bifurcation Analysis

open access: yesIEEE Access, 2020
In this paper, the problem of deep-stall recovery will be studied for the aircraft without longitudinal static stability. A new longitudinal short-period deep-stall model is established in the presence of time-varying distributed delays.

Solving Multiple Fleet Airline Disruption Problems Using a Distributed-Computation Approach to Integer Programming

open access: yesIEEE Access, 2017
The execution of the airline operation is often deviated from the original schedule due to some unexpected disruptions, such as aircraft breakdowns and severe weather conditions. In this situation, a recovery plan is needed to get the irregular operation

Model-Reference Reinforcement Learning for Safe Aerial Recovery of Unmanned Aerial Vehicles

open access: yesAerospace, 2023
In this study, we propose an aerial rendezvous method to facilitate the recovery of unmanned aerial vehicles (UAVs) using carrier aircrafts, which is an important capability for the future use of UAVs.

Fast Variable Neighborhood Search for Flight Rescheduling After Airport Closure

open access: yesIEEE Access, 2018
When an extreme weather event occurs, the temporary closure of airports is inevitable. In this case, airlines need to optimize their flight schedules in short order to reduce losses.

Application of dynamical systems theory to the high angle of attack dynamics of the F-14 [PDF]

open access: yes, 1990
Dynamical systems theory has been used to study the nonlinear dynamics of the F-14. An eight degree of freedom model that does not include the control system present in operational F-14's has been analyzed.
