First Flights with Neil Armstrong (39/39) : Propellers - Wings With A Twist

For educational purposes<br /><br />The Wright brothers realized that a propeller was a rotating wing – giving it a twist made it practical. <br /><br />By the mid 1930s, variable pitch and NACA research revolutionized propeller design. With the coming of the jet age, propellers fell out of favor for large aircraft. <br /><br />But designers soon realized that a fast turboprop with an advanced propeller could be more efficient than the best jetliners.<br /><br />Featured Aircraft: <br />- Wright Flyer<br />- scimitar prop Stiletto<br />- NASA Gulfstream 2 propfan testbed
