Stereolithography‚ was developed by 3D Systems of Valencia. Rapid Prototyping has also been referred to as solid free-form manufacturing‚ computer automated manufacturing‚ and layered manufacturing. RP models can be used for testing‚ such as when an airfoil shape is put into a wind tunnel. RP models can be used to create male models for tooling‚ such as silicone rubber molds and investment casts. In some cases‚ the RP part can be the final part‚ but typically the RP material is not strong or accurate

These effects can cause the aircraft to increase stalling speed or cause the aircraft to force downward in flight. Over the years‚ aircraft engines and airframes have changed dramatically. Modern day aircraft are aerodynamically less accepting of airfoil contamination than planes preceding them thus‚ giving the newer era aircraft somewhat of a handicap‚ creating more avenues for icing problems to arise. Because of this‚ investigators need to understand the scope of how icing and how it affects

CHAPTER 4 AIRCRAFT BASIC CONSTRUCTION INTRODUCTION Naval aircraft are built to meet certain specified requirements. These requirements must be selected so they can be built into one aircraft. It is not possible for one aircraft to possess all characteristics; just as it isn’t possible for an aircraft to have the comfort of a passenger transport and the maneuverability of a fighter. The type and class of the aircraft determine how strong it must be built. A Navy fighter must be fast‚ maneuverable

various systems that support the operation of an airplane. Wing A wing is a type of fin with a surface that produces aerodynamic force for flight or propulsion through the atmosphere‚ or through anothergaseous or liquid fluid. As such‚ wings have an airfoil shape‚ a streamlined cross-sectional shape producing a useful lift to drag ratio. Fuselage The fuselage (/ˈfjuːzəlɑːʒ/; from the French fuselé “spindle-shaped”) is an aircraft’s main body section that holds crew and passengers or cargo. In single-engine

Resource Management is the part of the initiative that will simplify and improve the manufacturing processes that are driven by the airplane configuration data. b) Wing Design- Aerodynamic Efficiency The 777 wing is the most aerodynamically efficient airfoil ever developed for subsonic commercial aviation. In a further refinement of designs introduced on the Boeing 757 and 767‚ the 777 wing features a long span with increased thickness. This advanced wing enhances the airplane’s ability to achieve higher
