HyperSizer
HyperSizer is computer-aided engineering (CAE) software used for stress analysis and sizing optimization of metallic and composite structures. Originally developed at the US National Aeronautics and Space Administration (NASA) as ST-SIZE, it was licensed for commercial use by Collier Research Corporation in 1996. Additional proprietary code was added and the software was marketed under the name HyperSizer. History HyperSizer developed from the NASA Langley Research Center (LaRC) ST-SIZE research code. ST-SIZE was originally developed because NASA identified a need for accurate methods of formulating panel stiffness and thermal expansion coefficients, leading to the development of ST-SIZE from 1988 to 1995. Another need was the reduction of mass on high-speed aircraft and weight reduction for optimization. ST-SIZE was developed by a team of engineers working on the National Aerospace Plane X-30. Two major versions of ST-SIZE were created. The original version included formulations ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Wind Turbine Design
Wind turbine design is the process of defining the form and configuration of a wind turbine to extract energy from the wind. An installation consists of the systems needed to capture the wind's energy, point the turbine into the wind, convert mechanical rotation into electrical power, and other systems to start, stop, and control the turbine. In 1919, German physicist Albert Betz showed that for a hypothetical ideal wind-energy extraction machine, the fundamental laws of conservation of mass and energy allowed no more than 16/27 (59.3%) of the wind's kinetic energy to be captured. This Betz' law limit can be approached by modern turbine designs which reach 70 to 80% of this theoretical limit. In addition to the blades, design of a complete wind power system must also address the hub, controls, generator, supporting structure and foundation. Turbines must also be integrated into power grids. Aerodynamics Blade shape and dimension are determined by the aerodynamic perfor ...

Learjet 85
The Learjet 85 was a Learjet development program by aircraft manufacturer Bombardier Aerospace. The program was launched on October 30, 2007 and a mockup of the aircraft was unveiled in October 2008 at the NBAA show in Orlando. The Learjet 85 was to fit between the midsize and the super midsize segments of the market. Designed for type certification under FAR-25, it was the first Bombardier Aerospace business jet to feature a composite structure. The plane was intended to have a high-speed cruise of Mach 0.82 and a transcontinental range of up to . On January 15, 2015, Bombardier announced their decision to suspend the Learjet 85 program and cut 1000 associated jobs. On October 29, 2015, Bombardier chief executive Alain Bellemare announced a 2015 $4.9 billion third quarter loss, including the cancellation of the Learjet 85 program. Design and development Computer software design tools were used on the project, including CATIA and HyperSizer, and similar wing technology employ ...

Failure Mode And Effects Analysis
Failure mode and effects analysis (FMEA; often written with "failure modes" in plural) is the process of reviewing as many components, assemblies, and subsystems as possible to identify potential failure modes in a system and their causes and effects. For each component, the failure modes and their resulting effects on the rest of the system are recorded in a specific FMEA worksheet. There are numerous variations of such worksheets. An FMEA can be a qualitative analysis, but may be put on a quantitative basis when mathematical failure rate models are combined with a statistical failure mode ratio database. It was one of the first highly structured, systematic techniques for failure analysis. It was developed by reliability engineers in the late 1950s to study problems that might arise from malfunctions of military systems. An FMEA is often the first step of a system reliability study. A few different types of FMEA analyses exist, such as: * Functional * Design * Process Sometime ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Micromechanics
Micromechanics (or, more precisely, micromechanics of materials) is the analysis of composite or heterogeneous materials on the level of the individual constituents that constitute these materials. Aims of micromechanics of materials Heterogeneous materials, such as composites, solid foams, polycrystals, or bone, consist of clearly distinguishable constituents (or ''phases'') that show different mechanical and physical material properties. While the constituents can often be modeled as having isotropic behaviour, the microstructure characteristics (shape, orientation, varying volume fraction, ..) of heterogeneous materials often leads to an anisotropic behaviour. Anisotropic material models are available for linear elasticity. In the nonlinear regime, the modeling is often restricted to orthotropic material models which does not capture the physics for all heterogeneous materials. Micromechanics goal is to predict the anisotropic response of the heterogeneous material on the b ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Lunar Atmosphere And Dust Environment Explorer
The Lunar Atmosphere and Dust Environment Explorer (LADEE; ) was a NASA lunar exploration and technology demonstration mission. It was launched on a Minotaur V rocket from the Mid-Atlantic Regional Spaceport on September 7, 2013. During its seven-month mission, LADEE orbited around the Moon's equator, using its instruments to study the lunar exosphere and dust in the Moon's vicinity. Instruments included a dust detector, neutral mass spectrometer, and ultraviolet-visible spectrometer, as well as a technology demonstration consisting of a laser communications terminal. The mission ended on April 18, 2014, when the spacecraft's controllers intentionally crashed LADEE into the far side of the Moon, which, later, was determined to be near the eastern rim of Sundman V crater. Planning and preparations LADEE was announced during the presentation of NASA's budget in February 2008. It was initially planned to be launched with the Gravity Recovery and Interior Laboratory (GRAIL) satell ...

Virgin Atlantic GlobalFlyer
The Scaled Composites Model 311 Virgin Atlantic GlobalFlyer ( registered N277SF) is an aircraft designed by Burt Rutan in which Steve Fossett first flew a solo nonstop airplane flight around the world in slightly more than 67 hours (2 days 19 hours) in 2005. The flight speed of set the world record for the fastest nonstop non-refueled circumnavigation, beating the mark set by the previous Rutan-designed Voyager aircraft at 9 days 3 minutes with an average speed of . The aircraft was owned by the pilot Steve Fossett, sponsored by Richard Branson's Virgin Atlantic airline, and built by Burt Rutan's company, Scaled Composites. The two companies subsequently worked together on Virgin Galactic. In February 2006, Fossett flew the GlobalFlyer for the longest aircraft flight distance in history: .
