Aircraft Sustainment and Repair

DescriptionAircraft Sustainment and Repair is a one-stop-shop for practitioners and researchers in the field of aircraft sustainment, adhesively bonded aircraft joints, bonded composites repairs, and the application of cold spray to military and civil aircraft. Outlining the state-of-the-art in aircraft sustainment, this book covers the use of quantitative fractography to determine the in-service crack length versus flight hours curve, the effect of intergranular cracking on structural integrity and the structural significance of corrosion. The book additionally illustrates the potential of composite repairs and SPD applications to metallic airframes.Key FeaturesCovers corrosion damage assessment and management in aircraft structuresIncludes a key chapter on U.S. developments in the emerging field of supersonic particle deposition (SPD)Shows how to design and assess the potential benefits of both bonded composite repairs and SPD repairs to metallic aircraft structures to meet the damage tolerance requirements inherent in FAA ac 20-107b and the U.S. Joint ServicesReadershipMaterials and aerospace scientists and engineers; practitioners in airworthiness, fatigue and fracture, adhesive bonding, maintenance and aircraft certification, fleet management; Researchers in the fields of cold spray, surface treatments and structural integrityTable of ContentsIntroduction and overviewFatigue requirements for aircraft structuresTypical fatigue-initiating discontinuities in metallic aircraft structuresPractical computational fracture mechanics for aircraft structural integrityCrack growth from naturally occurring material discontinuitiesAdhesively bonded repair/reinforcement of metallic airframe components: materials, processes, design and proposed through-life managementSurface treatment and repair bondingAnalysis, design and assessment of composite repairs to operational aircraftRepair of multi-site damage in civil transport aircraft – an example of the damage tolerant design of composite repairsThe F111C wing pivot fitting repair and implications for the design/assessment of bonded joints and composite repairsDevelopment and validation of bonded composite double repairs for commercial aircraftComputing the growth of naturally-occurring disbonds in adhesively-bonded jointsDelamination growth in polymer-matrix fibre composites and the use of fracture mechanics data for material characterisation and life predictionIntroduction to supersonic particle depositionAdditive metal technologies for aerospace sustainmentApplications of SPD to enhance the structural integrity of corroded airframesApplication of SPD to enhance the structural integrity of fuseage skins and centre barellsMultiplicative manufacturing and aircraft sustainment
