On the Measurement of Roller Skew of Tapered Roller Bearings
Roller skew in roller bearings can cause heat generation and reduce bearing life. Therefore, design to minimise its occurrence is essential in bearing development. This study investigated the roller skew of a double row ...
An integrated Solar-Fuel Cell Powered System for Airships
Development of a general model of power, propulsion and control of a novel airship is discussed in this paper. The airship design is based on the concept of the Multibody Advanced Airship for Transport (MAAT). The energy ...
Computational Modelling of Blades for a Novel Wind Turbine
Blades of a novel wind turbine system based on the principles of impulse turbines were designed in 3D and tested by computational fluid dynamics (CFD) simulation. This new turbine system is suitable to construct on the ...
Load sequence effect on fatigue damage
Reliable damage tolerant design of airframe structures relies on the accurate life prediction of fatigue cracks propagating from a detectable size to the critical size, which is challenging due to the complex load sequence ...
The Use of Pseudo-Inverse Methods in Reconstructing Loads on a Missile Structure
A missile during air carriage is subjected to high vibratory forces. These forces consequently impose high levels of stress on the attachment points to the aircraft. A repetitive application of stress causes fatigue. ...
Experimental evaluation into novel, low cost, modular PEMFC stack
The Polymer Electrolyte Membrane Fuel Cell (PEMFC), despite being regarded as an ideal replacement to the internal combustion engine, is still not an economically attractive pri-mover due to a number of key challenges that ...
