A highly technological 3D cross-sectional infographic showcasing the internal structure and operational principles of a modern commercial jet aircraft. The image features a semi-disassembled cross-section of the fuselage, wings, tail, and turbofan engine, with key components such as cockpit avionics, cabin framework, cargo hold, fuel tanks, wing ribs/spars, engine compressor/turbine, and landing gear mechanisms neatly disassembled and floating in arrangement, connected to the main body by guide lines. Each major part is labeled with clear, professional English annotations indicating structural names and brief functional descriptions. The overall layout is extremely clean and logical, with a pristine background, styled like a futuristic interactive high-end engineering blueprint, rendered in a cool color palette, evoking a professional, precise, and cutting-edge technological atmosphere.
