JNTUK B.Tech Aerospace Vehicle Structures –II gives you detail information of Aerospace Vehicle Structures –II R13 syllabus It will be help full to understand you complete curriculum of the year.
Course Objective
The main objective of the subject is to make the students to understand about structural analysis of most commonly used aircraft structures.The type of load come over the members like strigers,stiffeners.logirons,ribs and spars etc.The subject review the all basic structures and its.
UNIT – I : Load Diffision In Stiffned Panels: Wagner’s theory of beams. Shear carrying capabilities of panels and introduction to Tension field webs. Semi tension and complete tension field beams. Monocoque and semi Monocoque structures.
SHEET STRINGER COMBINATIONS: Axial Load flow diagrams for boom in stiffened panels. Simple illustrative examples of A/C sheet stringer elements through free body diagrams. Load diffusion in thin walled panels with oblique stiffeners.
UNIT – II : Stability Of Panels : Stability of stiffened panels. Effective width concept. Simple estimations of load carrying capability of stressed skins of Aircraft wing shells.
UNIT – III : Shear Flow In Open Sections Subjected To Pure Bendings Thin walled beams – Shear centre and Elastic axis Concept of shear flow beams with one axis of symmetry, Unsymmetrical box beam with effective and ineffective skins
UNIT – IV : Stress Analysis Of Wing And Fuselage : Procedure – Shear and bending moment distribution for semi cantilever and other types of wings and fuselages – Thin webbed beam with parallel and non parallel flanges – Shear resistant web beams.
UNIT – V : Torsion Bending Of Opend Tubes : Torsion bending phenomena. Torsion bending constant and specific torsion bending strength Simple derivation of torsion bending equation. The phenomena of warping. Stresses in cantilever, I-beam by solution of general differential equation for torsion beam.
UNIT – VI : Inhibition Of Axil Constraint Stress : Torsion of thin walled beams with open sections effect of axial constraints. Primary and Secondary warping phenomena. Computation of torsion bending constant for open tubes with cross sections such as Channel, T and Angle. Aircraft Skin Stiffners Methods of improving torsion bending strength by lipping, as an effective means of improving torsion bending constant. Computation of improvement of specific torsion bending strength in lipped Channel, T, I, L, sections over the unlipped counter parts
