For coordinates that are not smooth, the NASA AFSMO smoothing code (airfoil smoothing code) can be used to smooth the points.The original airfoils/coordinates do not, e.g. The coordinates give smooth inviscid velocity distributions, but some of Von Doenhoff) courtesy of Ralph Carmichael, PDAS: Corrected NACA coordinates from Theory of Airfoil Sections (Abbott and.NACA Report 93 (1921) includes coordinates and wind tunnel data on.Model airplane site, mostly focused on flying wings:.Martin Hepperle's site, including airfoil coordinates (mostly listed here as well) and lots.The TraCFoil website has many airfoils that are not included below.

IGES: Online CAD/CAM NURBS tool from Flusur.The plug-in can be installed via the Rhino Package Manager per: With Rhino 7 or newer and Rhino for Mac V7 or newer, Rhino Plug-In for importing airfoils into CAD/CAM NURBS.In addition to the links below, more airfoil-info links can be found back at the UIUC Airfoil Data Site homepage.The Incomplete Guide to Airfoil Usage: A useful aircraft/airfoil "reverse lookup" database from David Lednicer.The airfoils are listed alphabetically by the airfoil filename (which is usually close to the airfoil name).Īnswers to frequently asked questions are posted UIUC Airfoil Data Site gives some background As such, all of the data on this website is offered free to use with proper reference/citation.Included below are coordinates for approximately 1,600 airfoils (Version 2.0). Therefore, the creaters of this database hope to provide a resource that can be used to advance the development of UAVs. Contributions from Jane's, Roskam, and the NACA / NASA provides researchers with similar datasets for full-scale aircraft, leading to the development of modern-day aircraft however, although data provided by these researchers is still applicable towards UAVs, it may not accurately represent UAVs, as factors such mass and Reynolds scaling can change. the Selig UIUC databases, which provide low-Reynolds number data for airfoils and propellers.ĭatasets from various aircraft configurations and size classifications can be used for model development and validation and to predict the flight characteristics of similar aircraft, such as high or low wing configuration. There do, however, exist databases of UAV components, e.g. At the time of launching, January 2019, there existed no such open resource that include flight testing data of unmanned aircraft. The goal of the database is to provide researchers and enthusiasts with UAV flight and ground testing data to enable advancement while minimizing the need for repeated testing. Conducting flight testing is also risky and often requires certification (e.g. The effort may span many months or possibly years to develop an aircraft, which may only be flight tested for a limited time. In summation, these stages become extremely costly in terms of resources as well as time. Then comes ground testing, which may involve loads testing, moment of inertia measurement, and pre-flight combined systems testing. Next, instrumentation follows a similar development route. First the airframe must be developed, which may involve design creation. The development of a new UAV platform is a time-consuming task. Research UAVs are being developed to study flight/aerodynamic qualities and new aircraft configurations, develop new flight hardware and control algorithms, validate prediction and simulation methods, and as low-cost stand-ins for their full-scale counterparts. In the past several years, there has been a major increase in the popularity of unmanned aerial vehicles (UAVs) for a variety of applications and part of this uptrend includes an increase in research. The database is freely-available with the intention of distributing information to aid the advancement of aeronautical science and engineering research. The Unmanned Aerial Vehicle Database is an online source for data collected on unmanned aircraft and their sub-components.
