Avionics cooling-rate trade-off modelling for ultra-high capacity aircraft

Abstract: A computer aided conceptual aircraft design methodology (CACAD) has been developed to size ultra-high capacity jet transport aircraft. Modules were also developed for predicting maintenance costs of each airframe and avionics system and these were incorporated into CACAD. A methodology was developed to enhance the reliability of avionics systems, based on experimentally-proven engineering design solutions. A number of avionics cooling techniques were investigated, and reliability and maintainability models of thermal management were developed and linked to an avionics maintenance cost module. Further models were produced to investigate the impact of proposed changes on the environmental control systems, engine-provided bleeds and power off-takes. It was found that increased flowrates above the normally recommended values for the avionics bay, and to the flight deck instruments, may increase the reliability of the avionics systems, and also increase aircraft dispatch reliability. They may not, however, gre...

Aerospace and the environment what contribution can aerodynamics make

Abstract: For the past 50 years civil air transport has been dominated by the combination of the gas turbine and the B-47 airframe configuration. Both these machines owed their creation to WW2 and both represented revolutionary concepts at the time. Oyer the years, the engine and the airframe have undergone considerable detailed refinement. The changes have resulted in very impressive improvements in performance. However, it is now very clear that both are close to some well defined asymptotic limits that bound their performance. The result is that further potential improvements are smaller in percentage terms, become harder to achieve technically and, consequently, come at increasingly higher cost. A hugely successful global industry has developed around this standard configuration. Increasingly, more and more companies use aircraft and, as their businesses grow, the demand for aircraft and air transport increases. However, the ability of the environment to absorb this growth is beginning to be questioned and new ideas are required if aviation is to be regarded as an unbounded and a truly sustainable activity.

Análisis de la contaminación ambiental producida por el plasma frío de baja presión en la limpieza de láminas metálicas

Abstract: La presente investigacion aborda un analisis del nivel de contaminacion producido por los gases generados de monoxido de carbono (CO), dioxido de carbono (CO2) y los hidrocarburos (HC) en la limpieza de laminas metalicas de acero inoxidable AISI/SAE 304 aplicando plasma frio de oxigeno a baja presion para la remocion de los aceites ISO 32, ISO 68 e ISO 220, con diferentes parametros de control del generador de acuerdo con el aceite lubricante removido de la superficie de la lamina metalica de acero inoxidable. La experimentacion se realizo en un primer proceso con una descarga aplicada directamente a la superficie de la lamina impregnada con el aceite colocando con un volumen de 0,1 ml y en un segundo proceso donde la lamina con el aceite impregnado fue sumergida en un desengrasante para aceites y grasas con la finalidad de realizar una limpieza previa a la aplicacion del plasma frio a baja presion en la superficie. Para el analisis de los resultados en el nivel de gases generados por cada aceite se aplica un analisis estadistico para determinar si existe una diferencia significativa en el nivel de los gases generados en las dos etapas.
