Additive manufacturing of Kevlar reinforced epoxy composites
(American society of mechanical engineers (ASME), 2020-01)Additive manufacturing is defined as layer-by-layer deposition of materials on a surface to fabricate 3D objects with reduction in waste, unlike subtractive manufacturing processes. Short, flexible Kevlar fibers have been ... -
Aerodynamic Analysis Of A Vertically Landing Lifting Body
(Turkish Soc Thermal Sciences Technology, 2015)The vertical landing lifting body (VLLB) is a new concept for reusable launch vehicles, which launches vertically, but re-enters the atmosphere at a high angle of attack (alpha) for its entire flight. The VLLB remains at ... -
Aircraft Structural Safety : Effects of Explicit and Implicit Safety and Measures Uncertainty Reduction Mechanisms
(University of Florida, 2006)Aircraft structural safety is achieved by using different safety measures such as safety and knockdown factors, tests and redundancy. Safety factors or knockdown factors can be either explicit (e.g., load safety factor of ... -
Air ventilation and thermal comfort in a tramcar
