FAA -H-8083-1A, Aircraft Weight and Balance Handbook, has been prepared in recognition of the importance of weight and balance technology in conducting safe and efficient flight. This handbook begins with the basic principle of aircraft weight and balance control, emphasizing its importance and including examples of documentation furnished ...

This paper presents a three-dimensional airframe design methodology for low noise emission and high fuel efficiency, based on a blended-wing-body type aircraft. The design methodology uses a combination of high and low fidelity tools to assess the performance and acoustics of the aircraft. Three-dimensional view of the current ...

Although a high initial investment is necessary, laser welding is being more widely employed by companies requiring large quantities of multi-point welds. This method employs robots, welding at speeds of up to 150 inches (3.8 m) per minute. Other processes--plasma arc, ultrasonic, and electron beam welding--are also available, ...

Only authorized employees who have been properly trained shall be permitted to perform welding or cutting. Employees performing cutting or welding must wear the personal protective equipment required for the job. Clothing shall be free of excessive grease and oil. Fire extinguishers shall be readily available wherever cutting ...

How to Exploring Electric Circuits Using a Water Analogy, Water circuits provide an excellent comparison to simple electric circuits, but few students have experience with fluid dynamics. This lab allows a hands-on investigation of water flow: including current, pressure and resistance, in series and parallel arrangements, which can ...

It is thus the responsibility of the physics instructor to introduce his/her students to a variety of electric circuit models that will
enable those students encountering circuits for the first time to come up with their own coherent mental picture of current flow in an electric circuit. Electric circuit ...

Single view sketch-based modelers like SKETCH and Teddy can be powerful tools, but sometimes their inferences are inadequate: in Teddy, for example, if one draws an animal shape, the centerline of the tail will always lie in a plane rather than being curved in 3D. In these cases, ...

We present an image guided pen-based suggestive interface for sketching 3D wireframe models. Rather than starting from a blank canvas, existing 2D images of similar objects serve as a guide to the user. Image based filters enable attraction, smoothing, and resampling of input curves, and allows for their ...
