A computer program which simulates life and reliability of helicopter transmissions is presented. The helicopter transmissions may be composed of spiral bevel gear units and planetary gear units - alone, in series or in parallel. The spiral bevel gear units may have either single or dual input pinions, which are identical. The planetary gear units may be stepped or unstepped and the number of planet gears carried by the planet arm may be varied. The reliability analysis used in the program is based on the Weibull distribution lives of the transmission components. The computer calculates the system lives and dynamic capacities of the transmission components and the transmission. The system life is defined as the life of the component or transmission at an output torque at which the probability of survival is 90 percent. The dynamic capacity of a component or transmission is defined as the output torque which can be applied for one million output shaft cycles for a probability of survival of 90 percent. A complete summary of the life and dynamic capacity results is produced by the program.

System Life and Reliability Modeling for Helicopter Transmissions

When the Coalition Government came to power in 2010 in claimed it would deliver not just austerity, as necessary as that apparently was, but also fairness. This volume subjects this pledge to critical interrogation by exposing the interests behind the policy programme pursued and their damaging effects on class inequalities. Situated within a recognition of the longer-term rise of neoliberal politics, reflections on the status of sociology as a source of critique and current debates over the relationship between the cultural and economic dimensions of social class, the contributors cover an impressively wide range of relevant topics, from education, family policy and community to crime and consumption, shedding new light on the experience of domination in the early 21st Century.
