Aircraft limitations

This thesis investigates the SPH capability available in the commercial Finite Element (FE) code LS-DYNA®, for water impact problems. Experiments have been conducted on rigid wedges impacting water, which were then simulated with the SPH method. Although certain limitations were experienced with the experimental results, a positive correlation was observed with the numerical technique, thus establishing SPH as a promising method for crashworthiness design.

The use of detailed chemical reaction mechanisms of kerosene is still very limited in analyzing the combustion process in the combustion chamber of the aircraft engine. In this work, a new reduced chemical kinetic mechanism for fuel n-decane, which selected as a surrogate fuel for kerosene, containing 210 elemental reactions (including 92 reversible reactions and 26 irreversible reactions) and 50 species was developed, and the ignition and combustion characteristics of this fuel in both shock tube and flat-flame burner were kinetic simulated using this reduced reaction mechanism.

On September 13th , European Union Environment Commissioner Margot Wallström voiced concern over efforts by the United States to secure an international agreement to exempt airlines from emission levies or fuel taxes. Wallström told the European Parliament that the U.S. idea of discarding fiscal options would be "clearly contrary" to European environmental objectives. "For many years, the ICAO has been looking at market-based options designed to limit aviation emissions and introduce the aircraft and operating practices that are best environmentally," Wallström said.

On 5 August 1981, for reasons then given, this Court ordered that these proceedings be removed as a whole from the High Court to this Court for hearing and determination. They are proceedings, brought by way of application for judicial review, in which certain parts of the report of the Royal Commission on the Mount Erebus aircraft disaster are attacked. In summary the applicants claim that these parts are contrary to law, in excess of jurisdiction and in breach of natural justice. .One of the reasons for ordering the removal was that it was important that the complaints be finally...

Housing loans are considered to be relatively less risky due to their collateralised nature (Fitch Ratings (2006)). Moreover, the Philippine government extends housing loans to households under its National Shelter Program, which is aimed at addressing the country’s chronic housing shortage.

Single sampling devices and methods have their limitations in obtaining adequate smears from the cervix. A combination of two devices, usually spatula and endocervical brush, give better results. Triple smear or the vaginal-cervical-endocervical (VCE) technique can provide the best results. However, feasibility and cost factor need to be taken into consideration. In postmenopausal women, the squamo-columnar junction recedes making it difficult to obtain good amount of endocervical cells and cells from TZ.

Shocks in fluids result from fluid flow that is more rapid than the speed of a compression wave. Thus there is no means for the flow to adjust gradually. Pressure, velocity, and temperatures change abruptly, causing severe fatigue and component destruction in military aircraft and engine turbines. This problem is not limited to supersonic aircraft; many parts of subsonic craft are supersonic.

Innovation in engineering often means the clever use of a new material - new to a particular application, but not necessarily (although sometimes) new in the sense of ‘recently developed’. Plastic paper clips and ceramic turbine-blades both represent attempts to do better with polymers and ceramics what had previously been done well with metals. And engineering disasters are frequently caused by the misuse of materials.

This article concerns the rationale, history, principal issues, and potential of fuel cell-powered rail vehicles. Issues include fuel cell type, hydrogen storage, special factors affecting fuel cell rail, and the question of which rail applications are appropriate for hybrid powertrains. It concludes with a brief discussion of a supersonic concept vehicle, a cross between a train and an airplane that operates in a hydrogen-filled tube and levitates on a gas film, thereby overcoming an inherent efficiency limitation of aircraft. ...
