About this app
Paul Aerospace Works provides industry grade tools to generate Weibull and Lognormal failure probability distributions from data sets, calculates aircraft range and endurance from aircraft performance parameters, and compressible flow including normal shocks - with plan to regularly improve and add new tools and calculators. In the Pro version, Weibull's can be generated with suspension data, and all results can be exported. Also in Pro for compressible flow, you can select from multiple gases at different temperatures and generate the compressible flow and normal shock tables for your specific gas.
Latest release
What’s New
A reliability calculator has been added to quickly calculate unreliability given time or time given unreliability for both Weibull and Lognormal distributions. From the reliability distribution generators you can go directly to this calculator to quickly look at what-if scenarios. For generating Weibull and Lognormal distributions, you can now use shorthand to quickly add a number of parts with the same failure or suspension time. For example, "8@1300" would be 8 parts, each with 1300 hours.
