Quelques ennuis de plus dans la vie agit\u00e9e du JSF<\/h4>\n

Un probl\u00e8me de software<\/em> activant des vannes de contr\u00f4le d’alimentation en carburant a conduit d’abord \u00e0 des restrictions de vol des avions prototype de production du JSF, par Lockheed Martin, puis \u00e0 une immobilisation totale de tous les JSF, sur consigne du Pentagone, jusqu’\u00e0 ce que le probl\u00e8me soit r\u00e9solu. L’affaire est rapport\u00e9e le 1er octobre 2010<\/a> par Graham Warwick, d’AviationWeek.com<\/em>.<\/p>\n<\/p>\n

\t\u00abFlight tests of the F-35 Joint Strike Fighter have been suspended following the discovery of issues with fuel-system software on all variants and with a door hinge on the short-takeoff-and-vertical-landing (Stovl) version.<\/em><\/p>\n<\/p>\n

\t\u00bbThe Defense Department says flights are suspended temporarily pending modification of software that controls the engine’s three fuel boost pumps. Incorrect signal sequencing that could trigger a shut-down of all three pumps was discovered in the laboratory.<\/em><\/p>\n<\/p>\n

\t\u00bbManufacturer Lockheed Martin originally said flights were restricted to below 10,000 ft., the altitude below which boost pumps are not required, but the Pentagon says all flights were suspended earlier this week as a routine safety precaution.<\/em><\/p>\n<\/p>\n

\t\u00bbFlights in Stovl mode were suspended last week after post-flight inspection revealed an issue with the auxiliary-inlet door hinge on test aircraft BF-1. Efforts to find the root cause of the hinge problem and identify a solution continue.<\/em>\u00bb<\/p>\n<\/p>\n

\tDans une autre nouvelle (sur Ares<\/em>, le 1er octobre 2010<\/a>), Warwick annonce que le mat\u00e9riel de r\u00e9paration est en route et que la r\u00e9paration devrait \u00eatre assez rapide. Mais il souligne l’\u00e9vidence, qui est le revers de la m\u00e9daille de la c\u00e9l\u00e9brit\u00e9 du JSF, de son statut d’avion-miracle capable de tout faire, de la chasse g\u00e9n\u00e9rale \u00e0 toute critique contre ce programme alors qu’il en alimente tant par des multiples d\u00e9boires Bref, l’incident, m\u00eame s’il n’est pas en soi catastrophique et passerait relativement inaper\u00e7u dans un autre programme, est une tr\u00e8s mauvaise publicit\u00e9 de plus pour le programme, et une confirmation de son statut g\u00e9n\u00e9ral de plus en plus douteux. Ainsi va la vie, dans le monde de la communication o\u00f9 le JSF a fait ses choux gras pendant des ann\u00e9es ; d\u00e9sormais, ce serait plut\u00f4t les vaches maigres, et le syst\u00e8me de la communication le lui fait pas plus de cadeaux qu’il ne lui a \u00e9pargn\u00e9 les \u00e9loges dithyrambiques et fort excessifs in illo tempore<\/em>.<\/p>\n<\/p>\n

\t\u00abPrecautionary groundings are indeed routine in development programs, but in this case they only increase the pressure on a flight-test program already running late.<\/em> []<\/p>\n<\/p>\n

\t\u00bbWith Congress back at work finalizing the FY2011 defense budget, the F-35 grounding and test-stand failure of a GE\/Rolls F136 alternative engine will provide much grist to the political mill.<\/em><\/p>\n<\/p>\n
