The purported advantages of the blended wing body approach are efficient high-lift wings and a wide airfoil-shaped body. This enables the entire craft to contribute to lift generation with the result of potentially increased fuel economy. A fuselage is a long, thin body, usually with tapered or rounded ends to make its shape aerodynamically smooth. The fuselage may contain the flight crew, passengers, cargo or payload, fuel and engines. The pilots of manned aircraft operate them from a cockpit located at the front or top of the fuselage and equipped with controls and usually windows and instruments. The angle between two intersecting planes is called the Dihedral angle. A diamond is a 2-dimensional flat figure that has four closed and straight sides. Yes, it is a plane shape as it has two dimensions- length and width. The figure shown above is a flat surface extending in all directions. In geometry, a plane is a flat surface that extends into infinity. A fuselage, a long, thin body, ...
