What are the options for engine placement on aircraft?

Engine placement options: Wing-mounted podded - Common for large transports, good accessibility, reduced cabin noise, ground clearance limits engine diameter; Fuselage-mounted (aft) - Cleaner wing aerodynamics, lower asymmetric thrust issues, but aft CG range and structural challenges (MD-80, 727); Buried in fuselage - Minimum drag, used on fighters and some business jets, but access difficulties and inlet challenges; Embedded in wing - Flying wing concepts, reduced drag but integration complexity; and Wing-tip - Reduced induced drag potential, but structural and failure asymmetry concerns. Selection factors: Engine size and number, Noise considerations (shielding), Maintenance access, Flutter and whirl considerations, and Foreign object damage risk. Modern transports predominantly use under-wing podded engines for access, efficiency, and flexibility to accommodate engine upgrades.
