Abstract A novel methodology is presented for the reliability-based manufacturing cost optimisation of composite aircraft structures. comprehensive bottom-up costing approach employed, enabling precise estimation in terms material, machine, labour, tooling, and indirect costs. This splits process into many individual activities, which can be combined different ways, allowing proposed to applied...

During the design phase of an aircraft manufacturing system, different industrial scenarios need to be evaluated according key performance indicators achieve optimal system performance. It is a highly complex process involving multidisciplinary stakeholders, various digital tools and protocols. To address discontinuity challenge during this process, paper proposes tradespace framework based on ...

Laser-based ultrasonic techniques have been investigated for the nondestructive testing of advanced aeronautic composite structures for more than twenty years. Several organizations have evaluated the technology at various levels during this period. In one case, EADS (formerly Aerospatiale) acquired, jointly with Dassault Aviation, a laser ultrasonic system from a now defunct provider. In anoth...

Small, low-cost unmanned aerial vehicles (UAVs) are more prone to actuator failure and manufacturing variability than their larger, more expensive counterparts. To build a controller that was robust to this variability and these failure modes a linear quadratic regulator (LQR) was implemented to make the aircraft follow a desired trajectory, and then at regular intervals, a discrete time contin...

The aim of this paper is to explain the relationship between air pollutant-emissions and waiting times whilst aircrafts queue to access London Heathrow (LHR) runways. The approach to this problem is to develop a discrete-event simulation that describes the current landing and take-off operations, aircraft inter-arrivals and inter-departures, runway utilisation, and average waiting times for the...

Over recent years there has been a substantial growth in the number of industries employing project management methods (Chaffey, 1997), construction being one of the recognised first users of these techniques. Following the Latham (1994) and Egan (1998) reports in the UK, there appears to be a consensus that the construction industry could benefit by an examination of certain sectors of manufac...
