This paper reports the development of a new propeller design and analysis tool. JBLADE uses an improved version of blade element momentum that embeds a new model for the three-dimensional flow equilibrium. In addition, a new method for the prediction of the airfoil drag coefficient at a 90 deg angle of attack for a better poststall modeling is also presented. The software is developed as an open-source tool for the simulation of propellers and has the capability to estimate the performance of a given propeller geometry in design and offdesign operating conditions. The software allows the introduction of the blade geometry as an arbitrary number of sections. To validate the code, the propellers from NACA Technical Report 530 by Gray ("Wind-Tunnel Tests of Two Hamilton Standard Propellers Embodying Clark Y and NACA 16-Series Blade Sections," 1941) and NACA Technical Report 594 by Theodorsen et al. ("Characteristics of Six Propellers Including the High-Speed Range," 1937) were simulated and the results were checked against the experimental data and against those of other available codes. Although current development work is focused in the design of airship propellers, the long-term goal of the JBLADE development is to provide a user-friendly, accurate, and validated open-source code that can be used to design and optimize propellers for distinct applications. Presented as Papers 2013-4220 and 2013-4379 at the 2013 International Powered Lift Conference, Los Angeles, CA, 12-14 August 2013
