A combined configuration (αβ filter- TRIAD algorithm) for spacecraft attitude estimation based on in-Orbit Flight Data
Aerospace Systems - Tập 5 - Trang 223-232 - 2022
The attitude estimation has been viewed as one of the key technologies in space research works. It is used to convert the sensor measurement data to an estimated attitude using different estimation methods. However, because of the difficulty of space missions and tight computational budget most estimators suffer from height consuming which render them unsuitable. In this paper, the latter problem ...... hiện toàn bộ
Lattice flocking of multi-quadrotor system: an algorithm based on artificial potential field
Aerospace Systems - Tập 1 Số 1 - Trang 13-22 - 2018
Modal identification of double-layer hollow stiffened plate structure using variational mode decomposition based on high-speed digital image correlation
Aerospace Systems - Tập 5 - Trang 429-444 - 2022
The purpose of this study is to verify the applicability of the proposed non-contact optical vibration measurement techniques to identify modal parameters and the stiffness enhancement effect of the designed new stiffened plate structure. A thin-wall structure can bear a large load with less weight and fewer materials, which has attracted more and more attention in the field of aerospace, but its ...... hiện toàn bộ
Backstepping sliding mode-based anti-skid braking control for a civil aircraft
Aerospace Systems - Tập 6 - Trang 187-197 - 2023
Taking off and landing are critical phases and it is easy to happen flight disaster for them due to complex environment and weather. To improve flight safety of the aircraft, an anti-skid control method is proposed. First, the ground dynamics model of the civil aircraft is established. Second, a baseline controller is designed to control the velocity and yaw angle of the civil aircraft by Proporti...... hiện toàn bộ
Airfoil smoothing using unconditional optimization
Aerospace Systems - - Trang 1-11 - 2023
The paper considers the smoothing of tabulated curves describing airfoils. Smoothing is required to eliminate airfoil contour distortions that occur during the design of the aircraft wing surface. The problem of ensuring a smooth change in the curvature of the smoothed contour is presented as a problem of minimizing the quadratic function of many variables. To minimize the objective quadratic func...... hiện toàn bộ
Behavior of mixing enhancement in microscale shock cylindrical bubble interaction
Aerospace Systems - Tập 4 - Trang 143-149 - 2021
The investigation in the mixing characteristics of microscale shock cylindrical bubble interaction (SBI) provides a fundamental perspective into the microscale fuel injection. In present paper, the mixing performance of multi-scale SBI is numerically studied based on compressible Navier–Stokes equation. Starting from the bubble morphology, a scaling behavior of concentration distribution is exhibi...... hiện toàn bộ
Assessment of the use of electric power plants on the propeller-driven aircraft noise

Unscented Kalman filter-based method for spacecraft navigation using resident space objects
Aerospace Systems - Tập 3 - Trang 197-205 - 2020
The number of resident space objects (RSOs) in orbit has increased dramatically within the last 10 years. While RSOs pose a serious challenge to our continued use of space, these objects also provide an opportunity to improve on-orbit state estimation by detecting and identifying these objects using star trackers. While star trackers are currently used to determine the orientation of their host sp...... hiện toàn bộ
