A318/A319/A320/A321 Manufacturing Support Various projects were done for single aisle manufaturing support. These are: 1. Static and fatigue analyses was done on A320 Family spar flanges and butt strap joints for the use of oversize fasteners. The work involved methods and tool development for Concessions. 2. Evalution of fastener non-conformances for development of rules to support improved disposition of minor deviation and SRM concessions and repairs for AUK Broughton. Analysis covered all current single aisle derivatives including A318, A319, A320 and A321 for a variety of wing structural non-conformances.Wing analysis covered Spar flanges, Rib feet and skins / covers for fastener oversize, reduction of fasteners spacing and loss of edge distance conditions. 3. In developing the minor deviation rules tools for Auk Broughton, the calculation of fastener strength allowables, parametric lug analysis and edge distance evaulation were automated using Micosaoft excel and VBA code.
A320/A321 Aileron Re-Design The impact of a new aileron structural design on the loading, fatigue and crack growth life on the aileron support structure was analysed.
A320 Extended Service Goal (ESG)STRAND did a preliminary investigation of extending the current design service goal of A320 to Airbus requirements. Detailed crack growth analyses were done at attachments holes for gear rib support, forward pintle fittig and retraction jack fitting. New fatigue thresholds were calculated for spar flanges taking into accounts the EF2 tests.
A320 WingletThe performance of A320 can be improved by doing design changes to the exisiting A320 winglet. Two models were proposed by Airbus - Airbus Large Winglet and The Winglet Technology Elliptical Winglet. STRAND was involved in analysing the fatigue implications of using the new winglets. Two options for fit were considered - Retrofit or as a new build. |
