The analysis will consider the preliminary design of the main technology enablers, i.e. the advanced power gearbox (PGB) and the pitch change mechanism (PCM), delving into sizing, mechanical integrity aspects and optimal positioning of the components within the propulsion system. The study will then be extended to assess: Design for performance through simulated flight trajectory assessments over selected missions; Lifing aspects of the components and their implication on maintenance costs; Economic benefits through a financial viability analysis. A key requirement is to optimize these objectives by determining the minimum size of the power transmission system of the CROR engine to transmit power from the free turbine to the counter-rotating propellers. This requirement will need to be met without compromising its mechanical integrity nor the overall performance of the engine.Item Open Access New solutions for old problems(Cranfield University, 2018-10-18 10:05) Pontillo, Alessandro3 Minute Thesis presented at the Cranfield Doctoral Network Annual Event, September 2018.Highly flexible structures are now a common scenario in the aeronautic industry due to the adoption of slender and longer wings in order to reduce drag and increase the overall aircraft efficiency. Such configuration brings new challenges as structural dynamics now overlaps flight dynamics. Testing is then more important than ever. The Cranfield BEam Reduction and Dynamic Scaling (BEARDS) programme aims to provide a numerical and experimental tool able to dynamically scale-down a full aircraft and to test it successfully in the wind tunnel. Being able to predict static response along with structure dynamics, allows either universities and industry to mitigate the risk of testing bigger and more expensive models. The presentation will focus on the BEARDS methodology, results obtained from tests already done in the Weybridge wind tunnel and on the future of the programme with the new designed eXperimental Beards (XB-2) model.Item Open Access Robot Light Skin' paper data for Figures 5-11(Cranfield University, 2018-11-08 11:38) chun gilbert Tang, Chi; Webb, Phil; Thrower, JohnExperiment data used in the publication "The development and evaluation of Robot Light Skin: A novel robot signalling system to improve communication in industrial human–robot collaboration" for the concept validation of the Robot Light Skin (RLS), the data included correspond to the following figures in the publication: Reaction time to light signals fig 5, hit-rate fig 6, task performance fig 7, ease of monitoring fig 8, level of tiredness fig 9, and eye tracking fixation time fig 10 and 11.Item Open Access Conceptual and preliminary design methods for use on conventional and blended wing body airliners(Cranfield University, 2019-02-19 11:40) Smith, Howard; Fielding, JohnTranscript of John Fielding and Howard Smith's 1999 lecture to Court, Cranfield University.Item Open Access Experimental data for the dynamic inter-fibre failure of composite laminates with through-thickness reinforcement(Cranfield University, 2019-04-10 12:14) Cui, HaoExperimental data as published in "Dynamic inter-fibre failure of unidirectional composite laminates with through-thickness reinforcement" DOI: 10.1016/j.compscitech.2019.04.004Item Open Access Air jet flow control on pitching aerofoils(Cranfield University, 2019-07-08 09:09) Prince, Simon; Green, Richard; Khodaglian, VahikExperimental data on the effect of steady and pulsed air jet vortex generator blowing on a RAE9645 aerofoil section in dynamic stall.Item Open Access Stencil selection algorithms publication data(Cranfield University, 2019-08-19 14:40) Tsoutsanis, PanagiotisDataset for simulation1) eps images of simulation outputs2) mp4 /mpg of video animation of simulations3) tecplot plt files (use Tecplot, or Paraview for visualisation)
