A Comprehensive Study on the Aerodynamic Characteristics of Electrically Controlled Rotor Using Lattice Boltzmann Method

Aerospace, 2023
An electrically controlled rotor (ECR) is a kind of swashplateless rotor that implements the primary control via the trailing-edge flap system instead of a swashplate and demonstrates great potential in vibration reduction and noise alleviation.

Design and Experimental Study of Pressure Maintenance and Temperature Control System for Hydrate Pressure Core Processing Device

Energy Science &Engineering, Volume 14, Issue 7, Page 3162-3178, July 2026.
This paper presents a hydrate pressure core processing device integrated with a high‐precision active control system to perform nondestructive transfer, cutting, and analysis. To address the limitations of slow dynamic response and high thermal inertia in traditional passive systems, a differentiated control scheme is implemented.

Prediction of Slipper Pressure Distribution and Leakage Behaviour in Axial Piston Pumps Using ANN and MGGP

Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019
The pressure distribution (PD) and leakage between the slipper and swash plate in an axial piston pump (APP) have a considerable impact on the pump efficiency, affecting aspects such as the load bearing and wear performance of the slipper. Herein, multigene genetic programming (MGGP) and artificial neural network (ANN) machine learning methods (MLMs ...

Vibration and Performance Analyses Using Individual Blade Pitch Controls for Lift‐Offset Rotors

International Journal of Aerospace Engineering, Volume 2019, Issue 1, 2019., 2019
This work attempts to reduce the hub vibratory loads of a lift‐offset rotor using IBC (individual blade pitch control) in high‐speed forward flight. As a lift‐offset rotor for the present study, the rigid coaxial rotor of a XH‐59A compound helicopter is considered and CAMRAD II is used to predict the hub vibration and rotor performance.

Measurement of Slipper Behavior in Swashplate-Type Axial Piston Pumps

Tribology Online
In swash plate type axial piston pumps, slipper/swash plate sliding surfaces is subject to high fluctuating load. Therefore, the slippers are required to provide stable operation and reduce losses due to sliding. The behavior of the slipper fluctuates in

Active noise control by means of high frequency injection in electric motors

IET Electric Power Applications, Volume 18, Issue 8, Page 897-911, August 2024.
Aiming to improve the acoustics surrounding motor drives, this paper proposes the application of High Frequency Injection (HFI), with the aim of creating acoustic noise that is in anti‐phase relation to an unwanted noise. The injected High Frequency (HF) voltage produces torque pulsations and vibrations within the motor. This vibratory energy initiates

Maximizing wind farm power output with the helix approach: Experimental validation and wake analysis using tomographic particle image velocimetry

Wind Energy, Volume 27, Issue 5, Page 463-482, May 2024.
Abstract Wind farm control can play a key role in reducing the negative impact of wakes on wind turbine power production. The helix approach is a recent innovation in the field of wind farm control, which employs individual blade pitch control to induce a helical velocity profile in a wind turbine wake. This forced meandering of the wake has turned out
