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 ...

The race for speed ruled the early Jet Age on aviation. Aircraft manufacturers chased faster and faster planes in a fight for pride and capability. In the early 1970s, dreams were that the future would be supersonic, but fuel economy and unacceptable noise levels made that era never happen. After the 1973 oil crisis, the paradigm changed. The average cruise speed on newly developed aircraft started to decrease in exchange for improvements in many other performance parameters. At the same pace, the airliner’s power-plants are evolving to look more like a ducted turboprop, and less like a pure jet engine as the pursuit for the higher bypass ratios continues. However, since the birth of jet aircraft, the propeller-driven plane has lost its dominant place, associated with the idea that going back to propeller-driven airplanes, and what it represents in terms of modernity and security, has started a propeller avoidance phenomenon with travelers and thus with airlines. Today, even with the modest research effort since the 1980s, advanced propellers are getting efficiencies closer to jet-powered engines at their contemporary typical cruise speeds. This paper gives a brief overview of the performance trends in aviation since the last century. Comparison examples between aircraft designed on different paradigms are presented. The use of propellers as a reborn propulsive device is discussed.
About Me
Assistant Professor at University of Beira Interior (UBI). Currently, he is a researcher at C-MAST-Center for Mechanical and Aerospace Science and echnologies of UBI. He was a visiting researcher, in 1999, at CNRS Orleans. He has obtained his PhD at UBI in 2009 on Aerodynamics of SVTOL Aircraft Propulsion. He is experienced in developing aerospace vehicles and structures. He has been a consultant by UBI for Lockheed Martin Corporation (LMCO) designing a propeller for the DHIII UAV and lead a UBI team for a project of development of an unmanned underwater gliding vehicle in collaboration with the University of Saint Thomas,St Paul, MN, USA. Formerly, he has been invited and sponsored to participate in the LMCO co-organized quiet UAV competition: Silent Stamina. He has been the advisor teacher, pilot and team leader for UBI participations in Air Cargo Challenge design-build-fly international competition, winning the contest in 2003, 2007 and 2011. Currently he is faculty advisor and team member of the Aero@UBI Shell Eco Marathon Electric Prototype vehicle with two 6th positions as the best results obtained by Portugal in the category in 2018 and 2019. Main research interests are focused in aerodynamics, propulsion, performance and development of Aerospace Vehicles and structures.
