ALFLEX was built to establish the basic technology of automatic landing. The design featured a streamlined metal hull,
delta planiform wings, and large
winglets
Wingtip devices are intended to improve the efficiency of fixed-wing aircraft by reducing drag. Although there are several types of wing tip devices which function in different manners, their intended effect is always to reduce an aircraft's ...
