Mechanical failure is a significant issue in the aerospace industry. High material and manufacturing costs make the component repair an attractive option, avoiding the need to scrap parts when defects are detected. Low Energy Welding (LEW) is a micro-welding process that offers several advantages in repairing sensitive high-cost components. Extensive work has been carried out with the manual process. However, the process is relatively slow and the manual process is difficult to maintain constant quality.
Nowadays in aerospace industry, the main concern is to reach an optimum, reliable, and reproducible manufacturing process with a high predictability of the components service life and the lowest production cost. Machining is one of the main manufacturing processes for industrial parts which can change the surface characteristics of materials. The main aspects of these alterations are metallurgical, topographical, mechanical, and thermal which could affect microstructure, roughness, and residual stresses at the surface and near the surface of machined components, respectively.
We will fabricate cylindrical glass microstructures that keep light traveling in circles for a very long time. The circular trajectory of the confined light changes very sensitively due to rotational motion of the cylinders, and these changes can be measured by detecting angular velocity. Therefore, the project aims at developing these cylinders that allow light for many rounds of propagation without leaking, as a way to increase the sensitivity to rotations.
The aircraft flight deck has increased substantively in its complexity in recent years. The input systems are more complex, and the information feeds are much more detailed. In order for a pilot to interface effectively with the aircraft systems, the cockpit control functions must be laid out in an intuitive format. To do this, a trial and error approach is required, with meaningful input at each design phase.
Quadrotors are one of the most popular choices for unmanned aerial vehicles (UAVs) in situations where fast disturbance rejection, vertical takeoff and landing (VTOL) capabilities, and maneuverability are required. However, the quadrotor is inherently underactuated, and as a result, it is impossible to independently control the orientation and position of the vehicle. One solution to this problem involves rotors that can rotate relative to the vehicle frame, allowing for the angle of each rotor relative to the main vehicle frame to be independently controlled.
The world we live in is becoming increasingly dependent on electronic devices. With emerging technologies such as autonomous vehicles and smart cities, these devices will strongly influence the way we work, live, and play. In many applications, high reliability is desired, and the understanding of how and why a device should fail is essential in preventing future, potentially catastrophic events from occurring.
This project is intended to develop the technology to form high performance plastics reinforced with carbon fibre (polymer composites) in order to produce lighter parts to replace conventional metallic parts. As the parts may be exposed to fire during use, a comparison between different material systems under fire exposure is also required to have a better understanding of those materials in this condition and if they would withstand the necessary requirements.
Skyplan Services Ltd. is a company active in the air traffic management domain. The company is interested in expanding their current working application by benefiting from advanced technology to develop an integrated environment and solutions for air traffic management in order to provide better service at the international arena. Students to be involved in this project will build a data repository to host data to be collected, cleaned, built, integrated and processed for knowledge discovery which will guide more focused decision making.
Detecting maneuvers is important to a number of operational needs, such as to ease tracking of active satellites, discern and forecast the regular activity of a satellite, and detect deviations from nominal maneuver patterns. Although data on the orbits of satellites are publicly available on the internet, their precision is low and uncertain, which makes the task of detecting maneuvers complicated. The aim of this project is to develop and implement new techniques to recognize when maneuvers have occurred, and to give a first estimate of the magnitude and direction of such maneuvers.
The proposed project will contribute to Bombardiers research initiative Virtual Aircraft with the overall objective to improve modelling and simulation throughout the development process to enable innovation and reduce development risk to extensive design space exploration.
The objective of the project is to develop models of thermal aspects, traditionally investigated later in the design, when the aircraft architecture is already defined, to enable the development of an aircraft thermal architecture analysis and optimization.
