Report Criteria

Use the four designs in Figure 6. on The Safety of Aircraft Windows discussions page. and analyze the stress distribution around that feature. Assume the material is an aluminum alloy of: E = 70 GPa = 240 MPa Assume the a max • 240 MPa is the operating stress that must not be exceeded. If each of the four windows will have the stress facto ‘IC as that value. what will be the nominal stress around the window? Use Figure 7. on the The Safety of Aircraft Windows discussions page. as the relaxation ratio for all windows and determine how far away the windows must be to ensure the nominal stress level is reached.

Your aircraft shall show the estimate of the what and where the maximum stress will be on that window; estimate dimensions. Assume the height of each of the windows in Figure 6 is 350 mm. State any other assumptions you use. Comment on one of the following designs: • Why the 8 787 windows are larger than conventional aircraft • What window designs do they use on the Virgin Galactic or • The windows used on the Apollo 11 Capsule
No need to calculate but comment on an esoterical level what would be understood for this course content and what would need to be determined from any additional research.
