Resource reallocation across successive systemic innovations: How Rolls‐Royce shaped the evolution of the turbojet, turboprop, and turbofan

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary Despite the importance of resource reallocation in shaping a variety of strategic outcomes, strategy scholars have paid only limited attention to the processes by which firms reallocate their resources across successive systemic innovations.

The macro-fibre composite–bonded effect analysis on the micro-energy harvester performance and structural health–monitoring system of woven kenaf turbine blade for vertical axis wind turbine application

open access: yesAdvances in Mechanical Engineering, 2018
The application of vertical axis wind turbine is suitable in a low wind speed environment. Nevertheless, vertical axis wind turbine with kenaf turbine blade will promote an additional green concept by utilising biocomposite materials.

Investigating Breathing Dynamics of a 110 kV Oil‐Immersed Transformer Using Thermal‐Fluid‐Structure Interaction Modelling

open access: yesHigh Voltage, EarlyView.
ABSTRACT The breathing system of an oil‐immersed transformer is of vital importance for maintaining equilibrium between internal and external pressures, with any malfunction potentially disrupting the transformer's stable operation. This study develops a thermal–fluid–structure interaction (TFSI) model to simulate the breathing phenomenon in a 110 kV ...

Numerical Study on the Impact Pressure of Droplets on Wind Turbine Blades Using a Whirling Arm Rain Erosion Tester

open access: yesFluids
The leading-edge erosion of a wind turbine blade was tested using a whirling arm rain erosion tester, whose rotation rate is considerably higher than that of a full-scale wind turbine owing to the scale effect.

Study of Positive Corona Discharge of Needle Plate Electrodes in Airflow

open access: yesHigh Voltage, EarlyView.
ABSTRACT For high‐speed moving objects such as aircraft and wind turbine blades, discharge occurs under strong airflow. Research on lightning attachment characteristics has been extensive, whereas the role of corona discharge in pre‐breakdown streamer development has received less attention.

The Wind of Change: Mapping Wind Energy Growth and Multi‐Species Vulnerability in Sardinia, Mediterranean

open access: yesAnimal Conservation, EarlyView.
The rapid expansion of wind energy across the Mediterranean region calls for more advanced tools to assess and mitigate its impacts on biodiversity. In this study, we present an innovative approach combining 13‐year satellite imagery analysis and ecological modelling, to assess the spatiotemporal overlap between wind energy development and habitat ...

Use of the WEST-1 wind turbine simulator to predict blade fatigue load distribution [PDF]

open access: yes
To test the ability of WEST-1 to predict blade fatigue load distribution, actual wind signals were fed into the simulator and the response data were recorded and processed in the same manner as actual wind turbine data.
