波音707-320（B）汉莎航空 3D模型

This is low-poly model of Boeing 707-320B in Lufthansa livery. Model is fully textured (PBR textures, metalness and specular workflow); all animatable objects is separate (ailerons, slats, flaps, rudder, elevators, landing gears etc). Model is currently not rigged; delivered with all its parts in a static position and the landing gear down. Model made for games, real-time simulations, backgrounds and so on. Previews rendered in Unreal Engine 4. ******************************** Model info: *Polys: 3 596 *Verts: 3 561 *Tris: 6 633 Textures: 4096x4096 .TGA.

The wing was modified from the 320 by adding a second inboard kink, a dog-toothed leading edge, and curved low-drag wingtips instead of the earlier blunt ones. These wingtips increased overall wingspan by 3.0 ft. Takeoff gross weight was increased to 328,000 lb (149,000 kg). The 175 707-320B aircraft were all new-build; no original 320 models were converted to fan engines in civilian use. First service was June 1962, with Pan Am.
