Class Information
Number: 244/210
Name: Aeronautics > Aircraft sustentation > Sustaining airfoils > With lift modification > Variable > By controlling boundary layer > With nose slot
Description: Boundary layer control means comprising either an opening through the airfoil adjacent its leading edge, or an auxiliary element adjacent the leading edge for forming a slot therebetween, thus providing for deflection of the flow of the air at the leading edge.
