ARIANE 5 Flight 501 Failure
FOREWORD On 4 June 1996, the maiden flight of the Ariane 5 launcher ended in a failure. Only about 40 seconds after initiation of the flight sequence, at an altitude of about 3700 m, the launcher veered off its flight path, broke up and exploded. Engineers from the Ariane 5 project teams of CNES and Industry immediately started to investigate the failure. Over the following days, the Director G...
متن کاملModel Checking Ariane-5 Flight Program
This paper reports a veriication experiment carried out on a re-engineered description of a part of Ariane-5 Flight Program. This is the embedded software which solely controls the Ariane-5 launcher during its ight, from the ground, through the atmosphere and up to the nal orbit. In this case study, the Sdl language was used to describe the main functional behavior of the ight program including...
متن کاملMinimizing Flight Delay
In this paper, we model the problem of finding the minimum-delay route as a shortest path problem with stochastic costs. Our solution algorithm uses Monte Carlo simulation and network optimization techniques. Of particular novelty in our approach is the air network sampling that we use in order to accurately model the cascading effect of delays on flights. Our statistical models and simulations...
متن کاملCountdown to launch of the first microsatellites qualified for flight on Ariane-5 ASAP
In the fourth quarter of 2000, the first Ariane-5 to carry “piggy-back” payloads on the newly-designed ASAP ring is planned to be launched into a geo-synchronous orbit. The two 100kg spacecraft carried on the ring will be the second generation of microsatellites from the UK Defence Evaluation & Research Agency (DERA), called STRV-1c and –1d. Between them, these spacecraft carry 25 separate expe...
متن کاملAn analysis of the Ariane 5 flight 501 failure-a system engineering perspective
The report issued by the Inquiry Board in charge of inspecting the Ariane 5 flight 50.1 failure concludes that causes of the failure are rooted into poor S/W Engineering practice. From the failure scenario described in the Inquiry Board report, it is possible to infer what, in our view, are the real causes of the 501 failure. We develop arguments to demonstrate that the real causes of the 501 f...
