An airframe is the main structure of an aircraft, designed to support its various components and withstand aerodynamic forces during flight. It includes the fuselage, wings, tail, and landing gear, all of which work together to ensure stability and control. The airframe is typically made from materials like aluminum, composite materials, or titanium to balance strength and weight. The design of an airframe is crucial for the overall performance and safety of the aircraft. Engineers must consider factors such as aerodynamics, weight distribution, and structural integrity. Properly designed airframes contribute to the efficiency and effectiveness of aircraft like commercial airliners and military jets.
