The Design and Simulation of High Impedance Surface in Airborne Telemetry Antenna

open access: yesITM Web of Conferences, 2017
Aiming to the problems that excessive reduction of airborne telemetry antenna’s size will cause a sharp deterioration of the antenna’s bandwidth and gain, this paper proposed that using a high-impedance surface in the airborne telemetry antenna.

Protecting the flight test programme [PDF]

open access: yes, 2007
Considerable effort is put into the safety risk assessment of any flight test programme - and rightly so, since failures to apply best practice in this area may cause significant expense, and in extremis loss of life.

Aircraft sensor fault detection based on temporal two-dimensionalization

open access: yesXibei Gongye Daxue Xuebao, 2023
Aerial sensor fault detection is of great importance in flight missions. However, the dimensionality of sensor time-series data is extremely high and the time span is extremely long, which lead to poor detection performance of existing methods.

Practical aspects of modeling aircraft dynamics from flight data [PDF]

open access: yes, 1984
The purpose of parameter estimation, a subset of system identification, is to estimate the coefficients (such as stability and control derivatives) of the aircraft differential equations of motion from sampled measured dynamic responses. In the past, the
