Kharkiv KhAI-3
The Kharkiv KhAI-3 or Aviavnito-3 was one of several Soviet mid-1930s motor glider transports intended to reduce transport costs. Design and development Alexandr Alekseyevich Lazerev, who led the Kharkiv KhAI-3 Avianvito design team, already knew some of the problems posed by tailless aircraft. He was on the team which designed the almost uncontrollable KhAI-4 two years before (the Institute's designs did not always appear in their numerical order). That aircraft made only three flights before being grounded as dangerous. The much larger KhAI-3 was intended to show that low-powered aircraft could carry a useful eleven-passenger load with an engine producing just over . It was a tailless aircraft with a broad- chord wing and with a tractor engine, fin and rudder all on the centreline. Though there were initial thoughts of mounting the KhAI-3's Shvetsov M-11 five cylinder radial engine on a pylon over the wing, it was finally placed ahead of the leading edge on steel tubes fr ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Leading Edge
The leading edge of an airfoil surface such as a wing is its foremost edge and is therefore the part which first meets the oncoming air.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 305. Aviation Supplies & Academics, 1997. Characteristics Sweep Seen in plan the leading edge may be straight, curved, kinked or a combination of these. A straight leading edge may be swept or unswept, while curves or kinks always mean that part of the leading edge is swept. On a swept wing the sweep angle may differ from that of the wing, as wing sweep is conventionally measured at the airfoil 25% chord line. However on a delta wing the leading edge sweep defines the wing sweep. Radius and stagnation point A rounded leading edge helps to maintain a smooth airflow at varying angles of incidence to the airflow. Most subsonic airfoils therefore have a rounded leading edge. The degree of rounding is characterised by the profile radius at that point. The airflow divides to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
