Paul Aerospace Works

Paul Aerospace Works is a professional-grade engineering calculator app for aerospace and mechanical engineers. It brings Weibull reliability analysis, compressible flow and normal shock calculations, aircraft range and endurance, and the International Standard Atmosphere (ISA) together in one toolkit. WEIBULL & LOGNORMAL RELIABILITY ANALYSIS Fit Weibull and Lognormal failure probability distributions to your life data. A practical Weibull calculator for reliability engineering and failure analysis. COMPRESSIBLE FLOW & NORMAL SHOCK Solve compressible isentropic flow relations and normal shock problems for gas dynamics work. AIRCRAFT PERFORMANCE Calculate aircraft range and endurance from standard performance parameters. ISA STANDARD ATMOSPHERE Look up International Standard Atmosphere properties at altitude. PRIVATE BY DESIGN No accounts, no analytics, no tracking. All calculations run on your device. New tools and calculators are added regularly. PAUL AEROSPACE WORKS PRO unlocks: - Weibull analysis with suspensions (right-censored data) - Export of all results - Compressible flow and normal shock tables for multiple gases at different temperatures
